About Lorazepam
Lorazepam is approved in adults for the short-term management of anxiety disorders and anxiety-related insomnia, for the acute treatment of generalised tonic-clonic seizures and status epilepticus (parenteral form), and for pre-anaesthetic… Japan classifies medicines into prescription drugs (医療用医薬品) and OTC drugs (一般用医薬品), the latter further divided into pharmacist-only (第1類) and self-service classes. The Ministry of Health, Labour and Welfare (MHLW) sets the regulatory framework; PMDA reviews safety and efficacy.
Mechanism and action
Lorazepam binds the benzodiazepine site of the GABA-A receptor and allosterically enhances the action of the inhibitory neurotransmitter GABA.
Brands and generics in Japan
In Japan, Lorazepam is typically dispensed as one internationally recognised brand along with their corresponding authorised generics. Japanese pharmacies (薬局) and drugstores (ドラッグストア) such as Matsumoto Kiyoshi and Welcia are widespread. Prescription dispensing pharmacies (調剤薬局) are usually located near hospitals and clinics; pharmacist counselling at dispensing is mandated by the Pharmaceutical Affairs Law. Brand-to-generic substitution is decided by the pharmacist under local PMDA (Pharmaceuticals and Medical Devices Agency) equivalence rules, and the price difference in JPY is usually substantial.
Online and tele-prescribing access
Japan permits online sale of most OTC medicines under the 2014 amendments to the Pharmaceutical Affairs Law, with class-based restrictions. Online prescription dispensing is allowed via licensed pharmacies after a face-to-face or telemedicine consultation; personal importation of prescription medication is restricted to limited quantities for personal use. For Lorazepam specifically, the legal online options in Japan depend on its Rx-or-OTC classification under PMDA (Pharmaceuticals and Medical Devices Agency).
