UNDERSTANDING ZOLPIDEM: MECHANISM, PHARMACOKINETICS AND COMPARATIVE ANALYSIS AMONG Z-DRUGS – A COMPREHENSIVE REVIEW Authors: Kowsika G , SHANTHAKUMAR B AND KATHIRAVAN M K*
ABSTRACT
Insomnia is a prevalent medical condition and a major public health concern. In early stages
the benzodiazepines are used to treat the insomnia. To address the challenges possessed by
traditional benzodiazepine medications, commonly used to treat anxiety and insomnia, non-
benzodiazepine hypnotic agents known as z-drugs were introduced in the 1980s. Among these
agents, zolpidem stands out as an imidazopyridine hypnotic, selectively binding to the ?1 and
?5 subunits of the GABA-A receptor, offering a rapid onset and short-duration hypnotic effect.
Comparing with other non-benzodiazepines zolpidem has more potential for the treatment of
insomnia. Additionally, this article covers the recently developed area of deuterium
incorporation in drug design, showing how it can be used to enhance the therapeutic efficacy
and pharmacokinetic characteristics of drugs. This comprehensive review offers a thorough
summary of the state of insomnia medication today, pointing out the function of zolpidem and
the promising prospects for deuterium-based medication growth in addressing the unmet
requirements of patients with neurological disorders and sleep disorders.
