Metamizil is a central anticholinergic drug and a tranquilliser with powerful sedative and hypnotic effects; it was studied during the Soviet era by Soviet scientists alongside amizil.

Pharmacology

Metamizil acts as a muscarinic antagonist and, at a dose of 2 mg/kg, blocks the symptoms of parkinsonism (hypokinesia, rigidity and tremor). Metamizil was used as premedication, and is a strong sedative.

The median lethal dose following intraperitoneal administration was 118 mg/kg (mouse).

Uses

It has been suggested that it be used in the treatment of neuroses in dogs and humans. Sometimes as premedication (as a tranquilliser). As well as in the treatment of vascular parkinsonism and cerebral palsy.

Side effects

The reported side effects included dizziness and a dry mouth.
