Zhitong Financial App News, Xiansheng Pharmaceutical (02096) announced that on May 20, 2024, the insomnia drug Daliraxen hydrochloride tablets, which the Group cooperated with Idorsia Pharmaceuticals Ltd., obtained a drug/ product registration certificate issued by the Hong Kong Pharmaceuticals and Poisons Board, permitting “QUVIVIQ TABLETS 50MG” and “QUVIVIQ TABLETS 25MG” to be sold, offered for sale, distribution and possession in Hong Kong, China.

Daly Rayson is a dual orexin receptor antagonist (DORA) that blocks the binding of orexin neuropeptides (orexin A and orexin B) that promote wakefulness to their receptors. Unlike normal sedation to promote sleep, Dali Rayson only blocks the activation of orexin neuropeptides on orexin receptors. Therefore, Dali Rayson reduces the drive to wake up and induces sleep to occur without altering the structure of sleep.
