TOKYO, Jul 1, 2021 - (JCN Newswire via SEAPRWire.com) - Eisai Co., Ltd. announced today that its Hong Kong subsidiary Eisai (Hong Kong) Co., Ltd. has launched the in-house-discovered and developed orexin receptor antagonist DAYVIGO (generic name: lemborexant) for the treatment of adults with insomnia, characterized by difficulties with sleep onset and/or sleep maintenance. Eisai received approval for DAYVIGO in Hong Kong on February 28, 2021, and this launch is the first for DAYVIGO in Asia outside of Japan. DAYVIGO is a dual orexin receptor antagonist that inhibits orexin neurotransmission regulating sleep-wake rhythm by binding competitively to the two subtypes of orexin receptors (OX1R and OX2R). DAYVIGO acts on the orexin neurotransmitter system and is believed to facilitate sleep onset, sleep maintenance, and wake by regulating sleep-wake rhythm.DAYVIGO binds to orexin receptors OX1R and OX2R and acts as a competitive antagonist with stronger inhibition effect on OX2R, which suppresses both REM and non-REM sleep drive, such that DAYVIGO may provide faster sleep onset and better sleep maintenance to patients.DAYVIGO was launched in the U.S. and Canada for the treatment of adult...
