How Kemadrin works
Kemadrin is a muscle relaxing medication. It works by decreasing the activity of excess acetylcholine in the brain. This improves muscle control and reduces stiffness. It helps patients with Parkinson's disease by improving muscle control and reducing stiffness so that they can move more naturally. It is also used to treat movement disorder (restlessness, involuntary movements or muscle spasm ) which can be caused by certain drugs.

Mode of Action
Procyclidine is a tertiary amine antimuscarinic which acts by blocking excess acetylcholine at cerebral synapses. It also exhibits direct antispasmodic effect on smooth muscle.
Precaution
Patient w/ mental disorders, CV disease (e.g. tachycardia, cardiac arrhythmias, hypertention, hypotension). Hepatic and renal impairment. Avoid abrupt withdrawal. Elderly. Pregnancy and lactation. Patient Counselling This drug may cause blurred vision, dizziness, confusion or disorientation, if affected, do not drive or operate machinery. Monitoring Parameters Monitor symptoms of extrapyramydal syndrome or Parkinson's disease, pulse, anticholinergic effects (e.g. CNS, bowel and bladder function).
Side Effect
Dry mouth, mydriasis, blurred vision, lightheadedness, giddiness, disorientation, GI effects (e.g. nausea, vomiting, epigastric distress, constipation), allergic reaction (e.g. rash), muscular weakness; vertigo, confusion, hallucinations at high doses; tremor, acute suppurative parotitis.
Interaction
Increased plasma concentrations w/ paroxetine. Enhanced anticholinergic action w/ MAOIs and other anticholinergic drugs. Reduced therapeutic effect w/ cholinergic drugs. May antagonise the effect of parasympathomimetic agents. May reduce the absorption and therapeutic effect of sublingual or buccal nitrate tab. May reduce the efficacy of levodopa. May antagonise the GI effects of cisapride, domperidone and metoclopramide. May potentiate the vagolytic effects of quinidine. May reduce the absorption of ketoconazole.
