What is "tetrazepam"

n. A benzodiazepine drug with anticonvulsant, anxiolytic, hypnotic and muscle relaxant properties.

Tetrazepam (is marketed under the following brand names, Clinoxan, Epsipam, Myolastan, Musaril, Relaxam and Spasmorelax) is a benzodiazepine derivative with anticonvulsant, anxiolytic, muscle relaxant and slightly hypnotic properties. It was formerly used mainly in Austria, France, Belgium, Germany and Spain to treat muscle spasm, anxiety disorders such as panic attacks, or more rarely to treat depression, premenstrual syndrome or agoraphobia. Tetrazepam has relatively little sedative effect at low doses while still producing useful muscle relaxation and anxiety relief. The Co-ordination Group for Mutual Recognition and Decentralised Procedures-Human (CMD(h)) endorsed the Pharmacovigilance Risk Assessment Committee (PRAC) recommendation to suspend the marketing authorisations of tetrazepam-containing medicines across the European Union (EU) in April 2013. The European Commission has confirmed the suspension of the marketing authorisations for Tetrazepam in Europe because of cutaneous toxicity, effective from the 1 August 2013.

Delayed type 4 allergic hypersensitivity reactions including aculopapular exanthema, erythematous rash, urticarial eruption, erythema multiforme, photodermatitis, eczema and Stevens–Johnson syndrome can occasionally occur as a result of tetrazepam exposure. These hypersensitivity reactions to tetrazepam share no cross-reactivity with other benzodiazepines.
