Helidine Introduction

Helidine 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 Helidine

The most common use of Helidine is to treat the symptoms of Parkinson's disease, dystonia, and erratic eye movement associated with movement disorders. Helidine 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

Helidine works by blocking the action of acetylcholine, a neurotransmitter responsible for movement, on its receptors in the brain (muscarinic receptors). This leads to a reduction in the release of dopamine, which in turn reduces the overactive movements seen in movement disorders. It also helps to increase the action of a different neurotransmitter, gamma-aminobutyric acid (GABA), which results in an overall reduction in hyperactivity.
