Pyribenzamine

From Wikipedia, the free encyclopedia

Tripellenamine (Pyribenzamine) is a first generation antihistamine. It can be used in the treatment of asthma, hay fever, rhinitus and urticaria but is now less common as it has been replaced by newer antihistamines. This drug is sold in 50mg tablets, which are usually green in colour.

Pyribenzamine is a mildly sedating antihistamine. Other side effects can include gastrointestinal irritation, dry mouth, nausea and dizziness.

Pyribenzamine is sometimes abused recreationally in combination with the opiate pentazocine. It is dangerous to combine an opiate with a sedating antihistamine in this way.
