Clinical trials experience

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 practice. The adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse events that appear to be related to drug use and for approximating incidence rates.

Associated with discontinuation of treatment:
Approximately 4% of 1,701 patients who received zolpidem tartrate at all doses (1.25 to 90 mg) in U.S. premarketing clinical trials discontinued treatment because of an adverse reaction. Reactions most commonly associated with discontinuation from U.S. trials were daytime drowsiness (0.5%), dizziness (0.4%), headache (0.5%), nausea (0.6%), and vomiting (0.5%).

Approximately 4% of 1,959 patients who received zolpidem tartrate at all doses (1 to 50 mg) in similar foreign trials discontinued treatment because of an adverse reaction. Reactions most commonly associated with discontinuation from these trials were daytime drowsiness (1.1%), dizziness/vertigo (0.8%), amnesia (0.5%), nausea (0.5%), headache (0.4%), and falls (0.4%).

Data from a clinical study in which selective serotonin reuptake inhibitor (SSRI)-treated patients were given zolpidem tartrate revealed that four of the seven discontinuations during double-blind treatment with zolpidem (n=95) were associated with impaired concentration, continuing or aggravated depression, and manic reaction; one patient treated with placebo (n=97) was discontinued after an attempted suicide.

Most commonly observed adverse reactions in controlled trials:
During short-term treatment (up to 10 nights) with zolpidem tartrate at doses up to 10 mg, the most commonly observed adverse reactions associated with the use of zolpidem and seen at statistically significant differences from placebo-treated patients were drowsiness (reported by 2% of zolpidem patients), dizziness (1%), and diarrhea (1%). During longer-term treatment (28 to 35 nights) with zolpidem tartrate at doses up to 10 mg, the most commonly observed adverse reactions associated with the use of zolpidem and seen at statistically significant differences from placebo-treated patients were dizziness (5%) and drugged feelings (3%).

Adverse reactions observed at an incidence of ≥1% in controlled trials:
The following tables enumerate treatment-emergent adverse event frequencies that were observed at an incidence equal to 1% or greater among patients with insomnia who received zolpidem tartrate and at a greater incidence than placebo in U.S. placebo-controlled trials. Events reported by investigators were classified utilizing a modified World Health Organization (WHO) dictionary of preferred terms for the purpose of establishing event frequencies. The prescriber should be aware that these figures cannot be used to predict the incidence of side effects in the course of usual medical practice, in which patient characteristics and other factors differ from those that prevailed in these clinical trials. Similarly, the cited frequencies cannot be compared with figures obtained from other clinical investigators involving related drug products and uses, since each group of drug trials is conducted under a different set of conditions. However, the cited figures provide the physician with a basis for estimating the relative contribution of drug and nondrug factors to the incidence of side effects in the population studied.

The following table was derived from a pool of 11 placebo-controlled short-term U.S. efficacy trials involving zolpidem in doses ranging from 1.25 to 20 mg. The table is limited to data from doses up to and including 10 mg, the highest dose recommended for use.

The following table was derived from a pool of three placebo-controlled long-term efficacy trials involving oral zolpidem. These trials involved patients with chronic insomnia who were treated for 28 to 35 nights with zolpidem at doses of 5, 10, or 15 mg. The table is limited to data from doses up to and including 10 mg, the highest dose recommended for use. The table includes only adverse events occurring at an incidence of at least 1% for zolpidem patients.

Dose relationship for adverse reactions associated with oral zolpidem:
There is evidence from dose comparison trials suggesting a dose relationship for many of the adverse reactions associated with oral zolpidem use, particularly for certain CNS and gastrointestinal adverse events.

Oral tissue-related adverse reactions to Edluar:
The effect of chronic daily administration of Edluar on oral tissue was evaluated in a 60-day open-label study in 60 insomniac patients. One patient developed transient sublingual erythema, and another transient paresthesia of the tongue.

Adverse event incidence across the entire preapproval oral zolpidem database:
Zolpidem was administered to 3,660 subjects in clinical trials throughout the U.S., Canada, and Europe. Treatment-emergent adverse events associated with clinical trial participation were recorded by clinical investigators using terminology of their own choosing. To provide a meaningful estimate of the proportion of individuals experiencing treatment-emergent adverse events, similar types of untoward events were grouped into a smaller number of standardized event categories and classified utilizing a modified World Health Organization (WHO) dictionary of preferred terms.
The frequencies presented, therefore, represent the proportions of the 3,660 individuals exposed to zolpidem, at all doses, who experienced an event of the type cited on at least one occasion while receiving zolpidem. All reported treatment-emergent adverse events are included, except those already listed in the table above of adverse events in placebo-controlled studies, those coding terms that are so general as to be uninformative, and those events where a drug cause was remote. It is important to emphasize that, although the events reported did occur during treatment with zolpidem, they were not necessarily caused by it.
Adverse events are further classified within body system categories and enumerated in order of decreasing frequency using the following definitions: frequent adverse events are defined as those occurring in greater than 1/100 subjects; infrequent adverse events are those occurring in 1/100 to 1/1,000 patients; rare events are those occurring in less than 1/1,000 patients.

Side Effects by Body System - for Healthcare Professionals

General

In general, zolpidem is well-tolerated and causes little or no residual daytime effects in most young adult volunteers. Additionally, zolpidem does not significantly alter sleep architecture at recommended doses.

General side effects including fatigue have been reported.

Nervous system

Chronic use in high doses and subsequent withdrawal may induce grand mal seizures. Cases of falls have been reported in elderly patients.

Nervous system side effects most frequently have included visual disturbances, ataxia, and dizziness. Headache, drugged feeling, confusion, anterograde amnesia, excessive sedation, lightheadedness, delirium, nightmares, hallucinations, nervousness, and agitation have also been reported.

Hypersensitivity

Hypersensitivity side effects including rare cases of angioedema involving the tongue, glottis or larynx have been reported in patients after taking the first or subsequent doses of sedative-hypnotics, including zolpidem. Some patients have had additional symptoms such as dyspnea, throat closing, or nausea and vomiting that suggest anaphylaxis.

Some patients have required medical therapy in the emergency department. If angioedema involves the throat, glottis or larynx, airway obstruction may occur and be fatal. Patients who develop angioedema after treatment with zolpidem should not be rechallenged with the drug.

Gastrointestinal

Gastrointestinal side effects have included nausea, vomiting, dyspepsia, anorexia, and diarrhea. In clinical studies on the sublingual tablet, one patient developed transient sublingual erythema and another patient developed transient paresthesia of the tongue.

Other

Other side effects including tolerance to the pharmacologic effects of zolpidem have been reported rarely. Withdrawal symptoms after either abrupt cessation or fast tapering may occur. Withdrawal symptoms may include agitation, restlessness, anxiety, depression, insomnia, tremor, nausea, abdominal discomfort, and sweating.

Other side effects associated with the oral spray have included dry mouth.

A case of sleep driving has also been reported.

Psychiatric

Psychiatric side effects including cases of psychotic reactions have been reported in association with zolpidem therapy.

Respiratory

Zolpidem-induced respiratory depression may be responsive to flumazenil. Zolpidem-induced respiratory depression is generally not clinically significant at the usual hypnotic doses even in patients with impaired respiratory function.

One study has suggested that zolpidem doses of 20 mg (twice the usual dose) may cause apneic episodes in patients with obstructive sleep apnea.

Respiratory side effects have included respiratory depression which may occur at high doses. Upper respiratory infection and rhinitis have also been reported.

Cardiovascular

Cardiovascular side effects including palpitations have been reported in patients taking zolpidem.

Genitourinary

Genitourinary side effects including urinary incontinence and urinary tract infection have been reported.

Hepatic

Hepatic side effects include one case of hepatotoxicity associated with zolpidem given alone at therapeutic doses.

Immunologic

Immunologic side effects including infection have been reported infrequently.

Musculoskeletal

Musculoskeletal side effects including arthralgia and myalgia have been reported.
