Composition
ফার্মাকোলজি
Zolpidem is a GABA A receptor positive modulator presumed to exert its therapeutic effects in the short-term treatment of transient insomnia through binding to the benzodiazepine site of α1 subunit containing GABA A receptors, increasing the frequency of chloride channel opening resulting in the inhibition of neuronal excitation. Zolpidem binds to GABA A receptors with greater affinity for α1 subunit relative to α2 and α3 subunit containing receptors. Zolpidem has no appreciable binding affinity for α5 subunit containing GABA A receptors. This binding profile may explain the relative absence of myorelaxant effects in animal studies. Zolpidem has no appreciable binding affinity for dopaminergic D2, serotonergic 5HT2, adrenergic, histaminergic or muscarinic receptors.

Use another zolpidem tartrate immediate-release product for 5 mg and 10 mg dosing. In both males and females: If a 5 mg nightly dose of another zolpidem tartrate immediate-release product is not effective, the zolpidem tartrate dosage may be increased to Zolpidem Tartrate Capsules 7.5 mg once nightly or 10 mg once nightly of another zolpidem tartrate immediate-release product. The maximum recommended dosage of zolpidem tartrate immediate-release is 10 mg once nightly. Zolpidem Tartrate Capsules are for short-term use only. Administer Zolpidem Tartrate Capsules orally once per night immediately before bedtime with at least 7 to 8 hours remaining before the planned time of awakening.

There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to psychiatric medications during pregnancy. Limited data from published literature report the presence of zolpidem tartrate in human milk. There are reports of excess sedation in infants exposed to zolpidem tartrate through breastmilk.

CNS-Depressant Effects : Impaired alertness and motor coordination including risk of morning impairment. Risk increases with dose and use with other CNS depressants and alcohol. Caution patients against driving and other activities requiring mental alertness the morning after use. Instruct patients on correct use. Need to Evaluate for Comorbid Diagnoses : Reevaluate if insomnia persists after 7 to 10 days of use. Severe Anaphylactic/Anaphylactoid Reactions : Angioedema and anaphylaxis have been reported. Do not rechallenge if such reactions occur. Abnormal Thinking and Behavioral Changes : Changes including decreased inhibition, bizarre behavior, agitation, and depersonalization have been reported. Immediately evaluate any new onset behavioral changes. Depression : Worsening of depression or suicidal thinking may occur. Prescribe the least amount of capsules feasible to avoid intentional overdose. Respiratory Depression : Consider this risk before prescribing in patients with compromised respiratory function. Precipitation of Hepatic Encephalopathy : Avoid zolpidem tartrate in patients with severe hepatic impairment. Withdrawal Effects : Symptoms may occur with rapid dose reduction or discontinuation.
