Abuse
Information about the types of abuse that can occur with the drug and adverse reactions pertinent to those types of abuse, primarily based on human data. May include descriptions of particularly susceptible patient populations.9.2 Abuse Abuse and addiction are separate and distinct from physical dependence and tolerance. Abuse is characterized by misuse of the drug for non-medical purposes, often in combination with other psychoactive substances. Tolerance is a state of adaptation in which exposure to a drug induces changes that result in diminution of one or more of the drug effects over time. Tolerance may occur to both desired and undesired effects of drugs and may develop at different rates for different effects. Addiction is a primary, chronic, neurobiological disease with genetic, psychosocial, and environmental factors influencing its development and manifestations. It is characterized by behaviors that include one or more of the following: impaired control over drug use, compulsive use, continued use despite harm, and craving. Drug addiction is a treatable disease, using a multidisciplinary approach, but relapse is common. Studies of abuse potential in former drug abusers found that the effects of single doses of 40 mg of oral zolpidem tartrate were similar, but not identical, to diazepam 20 mg, while 10 mg of oral zolpidem tartrate was difficult to distinguish from placebo. Because persons with a history of addiction to or abuse of drugs or alcohol are at increased risk for misuse, abuse and addiction of zolpidem, they should be monitored carefully when receiving Zolpidem Tartrate Sublingual Tablets.
Controlled substance
Information about the schedule in which the drug is controlled by the Drug Enforcement Administration, if applicable.9.1 Controlled Substance Zolpidem tartrate is classified as a Schedule IV controlled substance by federal regulation.
Dependence
Information about characteristic effects resulting from both psychological and physical dependence that occur with the drug, the quantity of drug over a period of time that may lead to tolerance or dependence, details of adverse effects related to chronic abuse and the effects of abrupt withdrawl, procedures necessary to diagnose the dependent state, and principles of treating the effects of abrupt withdrawal.9.3 Dependence Physical dependence is a state of adaptation that is manifested by a specific withdrawal syndrome that can be produced by abrupt cessation, rapid dose reduction, decreasing blood level of the drug, and/or administration of an antagonist. Sedative-hypnotics have produced withdrawal signs and symptoms following abrupt discontinuation. These reported symptoms range from mild dysphoria and insomnia to a withdrawal syndrome that may include abdominal and muscle cramps, vomiting, sweating, tremors, and convulsions. The following adverse events which are considered to meet the DSM-III-R criteria for uncomplicated sedative-hypnotic withdrawal were reported during U.S. clinical trials with other oral zolpidem formulations following placebo substitution occurring within 48 hours following the last zolpidem treatment: fatigue, nausea, flushing, lightheadedness, uncontrolled crying, emesis, stomach cramps, panic attack, nervousness, and abdominal discomfort. These reported adverse events occurred at an incidence of 1% or less. However, available data cannot provide a reliable estimate of the incidence, if any, of dependence during treatment at recommended doses. Post-marketing reports of abuse, dependence, and withdrawal resulting from use of oral zolpidem tartrate have been received.
Drug abuse and dependence
Information about whether the drug is a controlled substance, the types of abuse that can occur with the drug, and adverse reactions pertinent to those types of abuse.9 DRUG ABUSE AND DEPENDENCE 9.1 Controlled Substance Zolpidem tartrate is classified as a Schedule IV controlled substance by federal regulation. 9.2 Abuse Abuse and addiction are separate and distinct from physical dependence and tolerance.

Overdosage of zolpidem tartrate
Information about signs, symptoms, and laboratory findings of acute ovedosage and the general principles of overdose treatment.10 OVERDOSAGE 10.1 Signs and Symptoms In post-marketing experience of overdose with oral zolpidem tartrate alone, or in combination with CNS-depressant agents, impairment of consciousness ranging from somnolence to coma, cardiovascular and/or respiratory compromise, and fatal outcomes have been reported. 10.2 Recommended Treatment General symptomatic and supportive measures should be used along with immediate gastric lavage where appropriate. Intravenous fluids should be administered as needed. Zolpidem's sedative-hypnotic effect was shown to be reduced by flumazenil and therefore flumazenil may be useful; however, flumazenil administration may contribute to the appearance of neurological symptoms (convulsions). As in all cases of drug overdose, respiration, pulse, blood pressure, and other appropriate signs should be monitored and general supportive measures employed. Hypotension and CNS depression should be treated by appropriate medical intervention. Sedating drugs should be withheld following zolpidem overdosage, even if excitation occurs. The value of dialysis in the treatment of overdosage has not been determined, although hemodialysis studies in patients with renal failure receiving therapeutic doses have demonstrated that zolpidem is not dialyzable. As with management of all overdosage, the possibility of multiple drug ingestion should be considered. The healthcare provider may wish to consider contacting a poison control center for up-to-date information on the management of hypnotic drug overdosage.
Adverse reactions
Information about undesirable effects, reasonably associated with use of the drug, that may occur as part of the pharmacological action of the drug or may be unpredictable in its occurrence. Adverse reactions include those that occur with the drug, and if applicable, with drugs in the same pharmacologically active and chemically related class. There is considerable variation in the listing of adverse reactions. They may be categorized by organ system, by severity of reaction, by frequency, by toxicological mechanism, or by a combination of these.6 ADVERSE REACTIONS Most commonly observed adverse reactions (> 1% in adult patients) are headache, nausea, and fatigue. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Lupin Pharmaceuticals, Inc. at 1-866-403-7592 or FDA at 1-800-FDA-1088 or http://www.fda.gov/medwatch The following serious adverse reactions in zolpidem-treated patients are discussed in greater detail in other sections of the labeling: Complex Sleep Behaviors [ See Warnings and Precautions (5.1) ] CNS-Depressant Effects and Next-Day Impairment [ see Warnings and Precautions (5.2)] Serious Anaphylactic and Anaphylactoid Reactions [ see Warnings and Precautions (5.2) ] Abnormal Thinking and Behavioral Changes [ see Warnings and Precautions (5.5) ] Withdrawal Effects [ see Warnings and Precautions (5.8) ] 6.1 Clinical Trials Experience The safety data described below are based on two double-blind placebo-controlled trials of Zolpidem Tartrate Sublingual Tablets in adult patients with insomnia characterized by difficulty returning to sleep after a middle-of-the-night awakening [see Clinical Studies (14.1) ]. These two trials included 230 and 82 patients treated with 3.5 mg and 1.75 mg of Zolpidem Tartrate Sublingual Tablets, respectively. The first study was a 3-way crossover sleep-laboratory study in 82 patients (58 female and 24 male; median age 47 years; 51% Caucasian, 44% African-American) of 1.75 mg and 3.5 mg of Zolpidem Tartrate Sublingual Tablets compared to placebo (Study 1). The second study was a 4-week, parallel-group at-home study in 295 patients (201 female and 94 male; median age 43 years) of 3.5 mg of Zolpidem Tartrate Sublingual Tablets compared to placebo, used on an as needed basis after spontaneous middle-of-the-night awakenings (Study 2). In Study 2, patients took Zolpidem Tartrate Sublingual Tablets during the night on 62% of study nights. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in actual practice. Table 1 shows the incidence of adverse reactions reported in Study 2 that occurred in 2% or more of Zolpidem Tartrate Sublingual Tablet-treated (3.5 mg) patients in which the incidence was greater than the incidence in placebo-treated patients. For women and other patients taking the 1.75 mg dose in Study 1, the incidence of adverse reactions was similar to the incidence seen with 3.5 mg of Zolpidem Tartrate Sublingual Tablets in Table 1. The most commonly reported adverse reactions in all treatment groups were headache, nausea, and fatigue.

zolpidem tartrate Drug Interactions
Information about and practical guidance on preventing clinically significant drug/drug and drug/food interactions that may occur in people taking the drug.7 DRUG INTERACTIONS CNS depressants, including alcohol: Possible adverse additive CNS depressant effects ( 5.1 , 7.1 ) Imipramine: Decreased alertness observed ( 7.1 ) Chlorpromazine: Impaired alertness and psychomotor performance observed ( 7.1 ) Rifampin: Combination use may decrease effects ( 7.2 ) Ketoconazole: Combination use may increase effects ( 7.2 ) 7.1 CNS-active Drugs Co-administration of zolpidem with other CNS depressants increases the risk of CNS depression [see Warnings and Precautions (5.2) ]. Zolpidem tartrate was evaluated in healthy volunteers in single-dose interaction studies for several CNS drugs. Imipramine Imipramine in combination with zolpidem produced no pharmacokinetic interaction other than a 20% decrease in peak levels of imipramine, but there was an additive effect of decreased alertness. Similarly, chlorpromazine in combination with zolpidem produced no pharmacokinetic interaction, but there was an additive effect of decreased alertness and psychomotor performance. Haloperidol A study involving haloperidol and zolpidem revealed no effect of haloperidol on the pharmacokinetics or pharmacodynamics of zolpidem. The lack of a drug interaction following single-dose administration does not predict the absence of an effect following chronic administration. Alcohol An additive adverse effect on psychomotor performance between alcohol and oral zolpidem was demonstrated [see Warnings and Precautions (5.2) ]. Sertraline Concomitant administration of zolpidem and sertraline increases exposure to zolpidem and may increase the pharmacodynamic effect of zolpidem. Fluoxetine After multiple doses of zolpidem tartrate and fluoxetine, an increase in the zolpidem halflife (17%) was observed. There was no evidence of an additive effect in psychomotor performance [see Clinical Pharmacology (12.3) ]. 7.2 Drugs that Affect Drug Metabolism via Cytochrome P450 Some compounds known to inhibit CYP3A may increase exposure to zolpidem. The effect of other P450 enzymes on the exposure to zolpidem is not known. Rifampin Rifampin, a CYP3A4 inducer, significantly reduced the exposure to and the pharmacodynamic effects of zolpidem. Use of Rifampin in combination with zolpidem may decrease the efficacy of zolpidem. Ketoconazole Ketoconazole, a potent CYP3A4 inhibitor, increased the pharmacodynamic effects of zolpidem. Consideration should be given to using a lower dose of zolpidem when ketoconazole and zolpidem are given together.
Clinical pharmacology
Information about the clinical pharmacology and actions of the drug in humans.12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Zolpidem, the active moiety of zolpidem tartrate, is a hypnotic agent with a chemical structure unrelated to benzodiazepines, barbiturates, or other drugs with known hypnotic properties. It interacts with a GABA-BZ complex and shares some of the pharmacological properties of the benzodiazepines. In contrast to the benzodiazepines, which nonselectively bind to and activate all BZ receptor subtypes, zolpidem in vitro binds the BZ 1 receptor preferentially with a high affinity ratio of the alpha 1 /alpha 5 subunits. This selective binding of zolpidem on the BZ 1 receptor is not absolute, but it may explain the relative absence of myorelaxant and anticonvulsant effects in animal studies as well as the preservation of deep sleep (stages 3 and 4) in human studies of zolpidem at hypnotic doses. 12.3 Pharmacokinetics Absorption Zolpidem Tartrate Sublingual Tablets disintegrates in the sublingual cavity after administration. On average, Zolpidem Tartrate Sublingual Tablets are rapidly absorbed in both genders, with a mean T max across studies of about 35 minutes to about 75 minutes. In healthy normal volunteers (age 21 to 45 years) dosed with 3.5 mg Zolpidem Tartrate Sublingual Tablets, the average C max and AUC were 77 ng/mL and 296 ng·h/mL, respectively in women. The average C max and AUC were 53 ng/mL and 198 ng·h/mL, respectively in men. In women, the average C max and AUC of the 1.75 mg Zolpidem Tartrate Sublingual Tablets dose were 37 ng/mL and 151 ng·h/mL, respectively. Food decreased the overall C max and AUC of Zolpidem Tartrate Sublingual Tablets 3.5 mg by 42% and 19%, respectively, and increased the time to peak exposure (T max ) to nearly 3 hours. For optimal effect, Zolpidem Tartrate Sublingual Tablets should not be administered with or immediately after a meal. Distribution Based on data obtained with oral zolpidem, the total protein binding was found to be 93% ± 0.1% and remained constant independent of concentration between 40 ng/mL and 790 ng/mL. Metabolism Based on data obtained with oral zolpidem, zolpidem tartrate is converted to inactive metabolites that are eliminated primarily by renal excretion. Elimination The elimination half-life of a single dose of a 3.5 mg Zolpidem Tartrate Sublingual Tablet is approximately 2.5 hours (range 1.4 to 3.6 hours). Special Populations Elderly : The recommended dose for Zolpidem Tartrate Sublingual Tablets is 1.75 mg. A pharmacokinetic study of 1.75 mg and 3.5 mg doses of Zolpidem Tartrate Sublingual Tablets showed that the plasma C max and AUC 0-4hr in elderly subjects following the 3.5 mg dose was higher by 34% and 30%, respectively, than the non-elderly subjects. The C max and AUC of 1.75 mg in elderly subjects were consistently lower than those observed for the 3.5 mg dose in non-elderly subjects but consistently higher than the 1.75 mg dose in non-elderly subjects. The elimination half-life remained unchanged. Hepatic Impairment : The pharmacokinetics of oral zolpidem tartrate in eight patients with chronic hepatic insufficiency were compared to results in subjects with normal hepatic function. Following a single 20 mg oral zolpidem tartrate dose, mean C max and AUC were found to be two times (250 ng/mL vs. 499 ng/mL) and five times (788 ng·hr/mL vs. 4203 ng·hr/mL) higher, respectively, in hepatically compromised patients compared to subjects with normal hepatic function. T max did not change. The mean half-life in cirrhotic patients of 9.9 hr (range: 4.1 to 25.8 hr) was greater than that observed in subjects with normal hepatic function of 2.2 hr (range: 1.6 to 2.4 hr). Dosing should be modified accordingly in patients with hepatic insufficiency [see Dosage and Administration (2.5)]. Renal Impairment: The pharmacokinetics of zolpidem tartrate were studied in 11 patients with end-stage renal failure (mean Cl Cr = 6.5 ± 1.5 mL/min) undergoing hemodialysis three times a week, who were dosed with zolpidem tartrate 10 mg orally each day for 14 or 21 days. No statistically significant differences were observed for C max , T max , half-life, and AUC between the first and last day of drug administration when baseline concentration adjustments were made. Zolpidem was not hemodialyzable. No accumulation of unchanged drug appeared after 14 or 21 days. Zolpidem pharmacokinetics were not significantly different in renally-impaired patients. No dosage adjustment is necessary in patients with renal impairment. Drug Interactions CNS-depressants Co-administration of zolpidem with other CNS depressants increases the risk of CNS depression [see Warnings and Precautions (5.1)]. Zolpidem tartrate was evaluated in healthy volunteers in single-dose interaction studies for several CNS drugs. Imipramine in combination with zolpidem produced no pharmacokinetic interaction other than a 20% decrease in peak levels of imipramine, but there was an additive effect of decreased alertness. Similarly, chlorpromazine in combination with zolpidem produced no pharmacokinetic interaction, but there was an additive effect of decreased alertness and psychomotor performance. A study involving haloperidol and zolpidem revealed no effect of haloperidol on the pharmacokinetics or pharmacodynamics of zolpidem. The lack of a drug interaction following single-dose administration does not predict the absence of an effect following chronic administration. An additive adverse effect on psychomotor performance between alcohol and oral zolpidem was demonstrated [see Warnings and Precautions (5.1)]. Following five consecutive nightly doses at bedtime of oral zolpidem tartrate 10 mg in the presence of sertraline 50 mg (17 consecutive daily doses, at 7:00 am, in healthy female volunteers), zolpidem C max was significantly higher (43%) and Tmax was significantly decreased (-53%). Pharmacokinetics of sertraline and N-desmethylsertraline were unaffected by zolpidem. A single-dose interaction study with zolpidem tartrate 10 mg and fluoxetine 20 mg at steady-state levels in male volunteers did not demonstrate any clinically significant pharmacokinetic or pharmacodynamic interactions. When multiple doses of zolpidem and fluoxetine were given at steady state and the concentrations evaluated in healthy females, an increase in the zolpidem half-life (17%) was observed. There was no evidence of an additive effect in psychomotor performance. Drugs that Affect Drug Metabolism via Cytochrome P450 Some compounds known to inhibit CYP3A may increase exposure to zolpidem. The effect of inhibitors of other P450 enzymes on the pharmacokinetics of zolpidem is unknown. A single-dose interaction study with zolpidem tartrate 10 mg and itraconazole 200 mg at steady-state levels in male volunteers resulted in a 34% increase in AUC 0-∞ of zolpidem tartrate. There were no pharmacodynamic effects of zolpidem detected on subjective drowsiness, postural sway, or psychomotor performance. A single-dose interaction study with zolpidem tartrate 10 mg and rifampin 600 mg at steady-state levels in female subjects showed significant reductions of the AUC (-73%), C max (-58%), and T 1/2 (-36 %) of zolpidem together with significant reductions in the pharmacodynamic effects of zolpidem tartrate. Rifampin, a CYP3A4 inducer, significantly reduced the exposure to and the pharmacodynamic effects of zolpidem. A single-dose interaction study with zolpidem tartrate 5 mg and ketoconazole, a potent CYP3A4 inhibitor, given as 200 mg twice daily for 2 days increased C max of zolpidem (30%) and the total AUC of zolpidem (70%) compared to zolpidem alone and prolonged the elimination half-life (30 %) along with an increase in the pharmacodynamic effects of zolpidem. Consideration should be given to using a lower dose of zolpidem when ketoconazole and zolpidem are given together. Other Drugs with No Interactions with Zolpidem A study involving cimetidine/zolpidem tartrate and ranitidine/zolpidem tartrate combinations revealed no effect of either drug on the pharmacokinetics or pharmacodynamics of zolpidem. Zolpidem tartrate had no effect on digoxin pharmacokinetics and did not affect prothrombin time when given with warfarin in healthy subjects.
Mechanism of action
Information about the established mechanism(s) of the drugÕs action in humans at various levels (for example receptor, membrane, tissue, organ, whole body). If the mechanism of action is not known, this field contains a statement about the lack of information.12.1 Mechanism of Action Zolpidem, the active moiety of zolpidem tartrate, is a hypnotic agent with a chemical structure unrelated to benzodiazepines, barbiturates, or other drugs with known hypnotic properties.

An additive adverse effect on psychomotor performance between alcohol and oral zolpidem was demonstrated [see Warnings and Precautions (5.1)]. Following five consecutive nightly doses at bedtime of oral zolpidem tartrate 10 mg in the presence of sertraline 50 mg (17 consecutive daily doses, at 7:00 am, in healthy female volunteers), zolpidem C max was significantly higher (43%) and Tmax was significantly decreased (-53%). Pharmacokinetics of sertraline and N-desmethylsertraline were unaffected by zolpidem. A single-dose interaction study with zolpidem tartrate 10 mg and fluoxetine 20 mg at steady-state levels in male volunteers did not demonstrate any clinically significant pharmacokinetic or pharmacodynamic interactions. When multiple doses of zolpidem and fluoxetine were given at steady state and the concentrations evaluated in healthy females, an increase in the zolpidem half-life (17%) was observed. There was no evidence of an additive effect in psychomotor performance. Drugs that Affect Drug Metabolism via Cytochrome P450 Some compounds known to inhibit CYP3A may increase exposure to zolpidem. The effect of inhibitors of other P450 enzymes on the pharmacokinetics of zolpidem is unknown. A single-dose interaction study with zolpidem tartrate 10 mg and itraconazole 200 mg at steady-state levels in male volunteers resulted in a 34% increase in AUC 0-∞ of zolpidem tartrate. There were no pharmacodynamic effects of zolpidem detected on subjective drowsiness, postural sway, or psychomotor performance. A single-dose interaction study with zolpidem tartrate 10 mg and rifampin 600 mg at steady-state levels in female subjects showed significant reductions of the AUC (-73%), C max (-58%), and T 1/2 (-36 %) of zolpidem together with significant reductions in the pharmacodynamic effects of zolpidem tartrate. Rifampin, a CYP3A4 inducer, significantly reduced the exposure to and the pharmacodynamic effects of zolpidem. A single-dose interaction study with zolpidem tartrate 5 mg and ketoconazole, a potent CYP3A4 inhibitor, given as 200 mg twice daily for 2 days increased C max of zolpidem (30%) and the total AUC of zolpidem (70%) compared to zolpidem alone and prolonged the elimination half-life (30 %) along with an increase in the pharmacodynamic effects of zolpidem. Consideration should be given to using a lower dose of zolpidem when ketoconazole and zolpidem are given together. Other Drugs with No Interactions with Zolpidem A study involving cimetidine/zolpidem tartrate and ranitidine/zolpidem tartrate combinations revealed no effect of either drug on the pharmacokinetics or pharmacodynamics of zolpidem. Zolpidem tartrate had no effect on digoxin pharmacokinetics and did not affect prothrombin time when given with warfarin in healthy subjects.

Nonclinical toxicology
Information about toxicology in non-human subjects.13 NONCLINICAL TOXICOLOGY 13.3 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis: Zolpidem was administered in the diet to rats and mice for 2 years at doses of 4, 18, and 80 mg base/kg/day. In mice, these doses are approximately 7, 30, and 140 times, respectively, the recommended human dose (RHD) of 3.5 mg/day (approximately 2.8 mg zolpidem base) on a mg/m 2 basis. In rats, these doses are approximately 15, 60, and 280 times, respectively, the RHD on a mg/m 2 basis. No evidence of carcinogenic potential was observed in mice. In rats, renal tumors (lipoma, liposarcoma) were seen at the mid- and high doses. Mutagenesis: Zolpidem was negative in in vitro (bacterial reverse mutation, mouse lymphoma, and chromosomal aberration) and in vivo (mouse micronucleus) genetic toxicology assays. Impairment of fertility: Oral administration of zolpidem (doses of 4, 20, and 100 mg base/kg/day) to rats prior to and during mating, and continuing in females through postpartum day 25, resulted in irregular estrus cycles and prolonged precoital intervals at the highest dose tested. The no-effect dose for these findings is approximately 70 times the RHD on a mg/m 2 basis. There was no impairment of fertility at any dose tested.

Clinical studies
This field may contain references to clinical studies in place of detailed discussion in other sections of the labeling.14 CLINICAL STUDIES 14.1 Middle-of-the-Night Awakening Trials Zolpidem Tartrate Sublingual Tablets were evaluated in two randomized, double-blind, placebo-controlled studies (Studies 1 and 2) in patients with insomnia characterized by difficulty returning to sleep after a middle-of-the-night (MOTN) awakening. In these studies, patients met the diagnosis for primary insomnia as defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) and had at least three prolonged MOTN awakenings per week that were at least 30 minutes in duration. Sleep Laboratory Study (Scheduled Dosing) Adult patients aged 19 to 64 years (N=82; 58 female, 24 male) with a history of difficulty returning to sleep after middle-of-the-night awakenings were evaluated in a double-blind, placebo-controlled, 3-period cross-over sleep laboratory study (Study 1). The primary outcome measure was latency to persistent sleep (LPS). Doses of 3.5 mg and 1.75 mg of Zolpidem Tartrate Sublingual Tablets significantly decreased both objective (by polysomnography) and subjective (patient-estimated) sleep latency after a scheduled middle-of-the-night awakening as compared to placebo. The effect on sleep latency was similar for females receiving 1.75 mg of Zolpidem Tartrate Sublingual Tablets and males receiving 3.5 mg of Zolpidem Tartrate Sublingual Tablets. Outpatient Study (As-needed Dosing) Adult patients aged 18 to 64 years (N=295; 201 women, 94 men) with difficulty returning to sleep after middle-of-the-night awakenings were evaluated in a double-blind, placebo-controlled 4-week outpatient study of Zolpidem Tartrate Sublingual Tablets. Patients took study drug (3.5 mg of Zolpidem Tartrate Sublingual Tablets or placebo) on an as needed (prn) basis, when they had difficulty returning to sleep after waking in the middle of the night, provided they had at least 4 hours time remaining in bed. Subjective (patient-estimated) time to fall back to sleep after middleof-the-night awakening was significantly shorter for Zolpidem Tartrate Sublingual Tablets 3.5 mg compared to placebo. 14.2 Special Safety Studies Driving Study A randomized, double-blind, placebo-controlled, active-control, single-center, four-period, crossover study in 40 healthy subjects was conducted to evaluate the effects of middle-of-the-night administration of Zolpidem Tartrate Sublingual Tablets on next-morning driving performance. The four randomized treatments included Zolpidem Tartrate Sublingual Tablets 3.5 mg four hours before driving, Zolpidem Tartrate Sublingual Tablets 3.5 mg three hours before driving, placebo, and a positive control (an unapproved sedative-hypnotic) given nine hours before driving. The primary outcome measure was the change in the standard deviation of lateral position (SDLP), a measure of driving impairment. The results were analyzed using a symmetry analysis, which determined the proportion of subjects whose change from their own SDLP in the placebo condition was statistically significantly above a threshold thought to reflect clinically meaningful driving impairment. When driving began 3 hours after taking Zolpidem Tartrate Sublingual Tablets, testing had to be terminated for one subject (a 23-year old woman) due to somnolence. Overall, the symmetry analysis showed a statistically significant impairing effect at 3 hours. When driving began 4 hours after taking Zolpidem Tartrate Sublingual Tablets, statistically significant impairment was not found, but numerically Zolpidem Tartrate Sublingual Tablets was worse than placebo. Zolpidem blood levels were not measured in the driving study, and the study was not designed to correlate specific blood level with degree of impairment. However, the estimated blood level of zolpidem in patients whose SDLP worsened according to the symmetry analysis is considered to present a risk for driving impairment. In some women, the 3.5 mg dose of Zolpidem Tartrate Sublingual Tablets results in zolpidem blood levels that remain at or sometimes considerably above this level 4 or more hours after dosing. Therefore, the recommended dose for women is 1.75 mg. A small negative effect on SDLP may remain in some patients 4 hours after the 1.75 mg dose in women, and after the 3.5 mg dose in men, such that a potential negative effect on driving cannot be completely excluded. Rebound effects In studies performed with other zolpidem formulations (5 mg to 10 mg oral zolpidem tartrate) given at bedtime, there was no objective (polysomnographic) evidence of rebound insomnia at recommended doses seen in studies evaluating sleep on the nights following discontinuation. There was subjective evidence of impaired sleep in the elderly on the first post-treatment night at doses above the recommended elderly dose of 5 mg oral zolpidem tartrate. Memory impairment in controlled studies Controlled studies in adults utilizing objective measures of memory yielded no consistent evidence of next-day memory impairment following the administration at bedtime of 5 mg to 10 mg oral zolpidem tartrate. However, in one study involving zolpidem tartrate doses of 10 mg and 20 mg, there was a significant decrease in next-morning recall of information presented to subjects during peak drug effect (90 minutes post-dose), i.e., these subjects experienced anterograde amnesia. There was also subjective evidence from adverse event data for anterograde amnesia occurring in association with the administration of oral zolpidem tartrate, predominantly at doses above 10 mg.
Geriatric use
Information about any limitations on any geriatric indications, needs for specific monitoring, hazards associated with use of the drug in the geriatric population.8.5 Geriatric Use Zolpidem Tartrate Sublingual Tablets dosage adjustment is necessary in geriatric patients. Sedating drugs may cause confusion and over-sedation in the elderly; elderly patients generally should be started on low doses of Zolpidem Tartrate Sublingual Tablets and observed closely [see Dosage and Administration (2.4) , and Clinical Pharmacology (12.3) ]. Clinical trial experience with other zolpidem formulations (5 mg to 10 mg oral zolpidem tartrate) given at bedtime: A total of 154 patients in U.S.-controlled clinical trials and 897 patients in non-U.S. clinical trials who received oral zolpidem were ≥ 60 years of age. For a pool of U.S. patients receiving oral zolpidem tartrate at doses of ≤ 10 mg or placebo, there were three adverse reactions occurring at an incidence of at least 3% for zolpidem and for which the zolpidem incidence was at least twice the placebo incidence (see Table 2). Falls in geriatric patients: A total of 30/1,959 (2%) non-U.S. patients receiving other zolpidem formulations (5 mg to 10 mg oral zolpidem tartrate) reported falls, including 28/30 (93%) who were ≥ 70 years of age. Of these 28 patients, 23 (82%) were receiving zolpidem tartrate doses > 10 mg. A total of 24/1,959 (1%) non-U.S. patients receiving zolpidem reported confusion, including 18/24 (75%) who were ≥70 years of age. Of these 18 patients, 14 (78%) were receiving zolpidem tartrate doses >10 mg. The dose of Zolpidem Tartrate Sublingual Tablets in elderly patients is 1.75 mg to minimize adverse effects related to impaired motor and/or cognitive performance and unusual sensitivity to sedative-hypnotic drugs. Table 2: Adverse Reactions in Geriatric Patients in Pooled Trials of 5 mg to 10 mg of Oral Zolpidem Tartrate Given at Bedtime Adverse Reaction 5 to 10 mg Oral Zolpidem Tartrate Placebo Dizziness 3% 0% Drowsiness 5% 2% Diarrhea 3% 1%

Information about any limitations on any pediatric indications, needs for specific monitoring, hazards associated with use of the drug in any subsets of the pediatric population (such as neonates, infants, children, or adolescents), differences between pediatric and adult responses to the drug, and other information related to the safe and effective pediatric use of the drug.8.4 Pediatric Use Zolpidem Tartrate Sublingual Tablets are not recommended for use in children. Safety and effectiveness of Zolpidem Tartrate Sublingual Tablets have not been established in pediatric patients below the age of 18. In an 8-week study in pediatric patients (aged 6 to 17 years) with insomnia associated with ADHD, an oral solution of zolpidem tartrate dosed at 0.25 mg/kg at bedtime did not decrease sleep latency compared to placebo. Hallucinations were reported in 7% of the pediatric patients who received zolpidem; none of the pediatric patients who received placebo reported hallucinations.
Pregnancy
Information about effects the drug may have on pregnant women or on a fetus. This field may be ommitted if the drug is not absorbed systemically and the drug is not known to have a potential for indirect harm to the fetus. It may contain information about the established pregnancy category classification for the drug. (That information is nominally listed in the teratogenic_effects field, but may be listed here instead.)8.1 Pregnancy Pregnancy Category C There are no adequate and well-controlled studies of zolpidem in pregnant women. Studies in children to assess the effects of prenatal exposure to zolpidem have not been conducted; however, cases of severe neonatal respiratory depression have been reported when zolpidem was used at the end of pregnancy, especially when taken with other CNS-depressants. Children born to mothers taking sedative-hypnotic drugs may be at risk for withdrawal symptoms during the postnatal period. Neonatal flaccidity has also been reported in infants born to mothers who received sedative-hypnotic drugs during pregnancy. Zolpidem Tartrate Sublingual Tablets should be used during pregnancy only if the potential benefit outweighs the potential risk to the fetus. Administration of zolpidem to pregnant rats and rabbits resulted in adverse effects on offspring at doses greater than the recommended human dose (RHD) of 3.5 mg/day (approximately 2.8 mg/day zolpidem base); however, teratogenicity was not observed. When zolpidem was administered at oral doses of 4, 20, and 100 mg base/kg/day to pregnant rats during the period of organogenesis, dose-related decreases in fetal skull ossification were observed at all but the lowest dose, which is approximately 15 times the RHD on a mg/m 2 basis. In rabbits treated during organogenesis with zolpidem at oral doses of 1, 4, and 16 mg base/kg/day, increased embryo-fetal death and incomplete fetal skull ossification were seen at the highest dose tested. The no-effect dose for embryo-fetal toxicity in rabbits is approximately 30 times the RHD on a mg/m 2 basis. Administration of zolpidem to rats at oral doses of 4, 20, and 100 mg base/kg/day during the latter part of pregnancy and throughout lactation produced decreased offspring growth and survival at all but the lowest dose, which is approximately 15 times the RHD on a mg/m2 basis.
Use in specific populations
Information about use of the drug by patients in specific populations, including pregnant women and nursing mothers, pediatric patients, and geriatric patients.8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, zolpidem may cause fetal harm. ( 8.1 ) Pediatric use: Safety and effectiveness of zolpidem not established. With bedtime dosing of zolpidem, hallucinations observed (incidence 7%) ( 8.4 ) 8.1 Pregnancy Pregnancy Category C There are no adequate and well-controlled studies of zolpidem in pregnant women.

Hallucinations were reported in 7% of the pediatric patients who received zolpidem; none of the pediatric patients who received placebo reported hallucinations. 8.5 Geriatric Use Zolpidem Tartrate Sublingual Tablets dosage adjustment is necessary in geriatric patients. Sedating drugs may cause confusion and over-sedation in the elderly; elderly patients generally should be started on low doses of Zolpidem Tartrate Sublingual Tablets and observed closely [see Dosage and Administration (2.4) , and Clinical Pharmacology (12.3) ]. Clinical trial experience with other zolpidem formulations (5 mg to 10 mg oral zolpidem tartrate) given at bedtime: A total of 154 patients in U.S.-controlled clinical trials and 897 patients in non-U.S. clinical trials who received oral zolpidem were ≥ 60 years of age. For a pool of U.S. patients receiving oral zolpidem tartrate at doses of ≤ 10 mg or placebo, there were three adverse reactions occurring at an incidence of at least 3% for zolpidem and for which the zolpidem incidence was at least twice the placebo incidence (see Table 2). Falls in geriatric patients: A total of 30/1,959 (2%) non-U.S. patients receiving other zolpidem formulations (5 mg to 10 mg oral zolpidem tartrate) reported falls, including 28/30 (93%) who were ≥ 70 years of age. Of these 28 patients, 23 (82%) were receiving zolpidem tartrate doses > 10 mg. A total of 24/1,959 (1%) non-U.S. patients receiving zolpidem reported confusion, including 18/24 (75%) who were ≥70 years of age. Of these 18 patients, 14 (78%) were receiving zolpidem tartrate doses >10 mg. The dose of Zolpidem Tartrate Sublingual Tablets in elderly patients is 1.75 mg to minimize adverse effects related to impaired motor and/or cognitive performance and unusual sensitivity to sedative-hypnotic drugs. Table 2: Adverse Reactions in Geriatric Patients in Pooled Trials of 5 mg to 10 mg of Oral Zolpidem Tartrate Given at Bedtime Adverse Reaction 5 to 10 mg Oral Zolpidem Tartrate Placebo Dizziness 3% 0% Drowsiness 5% 2% Diarrhea 3% 1% 8.6 Gender Difference in Pharmacokinetics Women cleared zolpidem tartrate from the body after sublingual administration of a 3.5 mg dose of Zolpidem Tartrate Sublingual Tablets at a lower rate than men (2.7 mL/min/kg vs. 4.0 mL/min/kg). C max and AUC parameters of zolpidem were approximately 45% higher at the same dose in female subjects compared with male subjects. Given the higher blood levels of zolpidem tartrate in women compared to men at a given dose, the recommended dose of Zolpidem Tartrate Sublingual Tablets for women is 1.75 mg, and the recommended dose for adult men is 3.5 mg.
