Abstract
Insomnia is one of the major challenges in medical science nowadays as it leads to the great socio-economic burden by impairing daytime function as well as the development of exhaustion, depression and memory disturbance in affected individuals. Several important classes of drugs have been tried including the BZDs and Non-BZD hypnotics. Available drugs to combat this disease have the limitations of abuse potential, tolerance and cognitive impairments. In some instances, withdrawal symptoms have been observed on abrupt cessation of those drugs. The Orexin system has been very recently targeted as a therapeutic option to overcome those limitations. Daridorexant as a Dual Orexin Receptor Antagonists (DORA) in the treatment of insomnia has been evaluated in several preclinical and clinical studies. Available information obtained from those studies has shown promising future for this drug in the management of insomnia. Beyond its effectiveness in insomnia, it has been successfully used in patients suffering from Obstructive sleep apnoea, Chronic Obstructive Airway Disease (COAD), Alzheimer’s Disease (AD), hypertension and cardiovascular disorders. Larger studies need to address the safety issues as well as obtain robust pharmacovigilance information to safeguard the risk-benefit aspect of this drug in insomniac adults.
