Picidin Introduction

Picidin is an anticholinergic drug used to treat the symptoms of Parkinson's and other movement disorders.It is a dopamine receptor agonist, typically prescribed as either the hydrochloride or besilate salt and is marketed under the brand names Kemadrin and Procyclid. It is available as oral tablets, syrup, and injectable solution.

Uses For Picidin

The most common use of Picidin is to treat the symptoms of Parkinson's disease, dystonia, and erratic eye movement associated with movement disorders. Picidin can also help to reduce stiffness and trembling, alleviating the stiffness and bradykinesia associated with Parkinson's: it can help to reduce tremor, rigidity, and difficulty in initiating movement. It may also be beneficial for restless legs syndrome, spasticity, alcohol withdrawal, some types of epilepsy, and other neurological conditions.

Mechanism of Action

Picidin works by blocking the action of acetylcholine, a neurotransmitter responsible for movement, on its receptors in the brain (muscarinic receptors).
