## Primary Indications
* Management of Parkinson's disease symptoms, particularly tremor and rigidity.
* Treatment of drug-induced extrapyramidal symptoms.
## Adult Dosing
The usual starting dose is 1 mg orally once or twice daily, with gradual increases as tolerated. Typical maintenance doses range from 2 mg to 6 mg per day, divided into 2 or 3 doses. The maximum recommended daily dose is generally 10 mg. Titration should be slow to minimize side effects.
## Pediatric Dosing
There is no established pediatric dosing. Use in children is generally not recommended due to potential for severe anticholinergic effects.
## Dose Adjustments
* **Hepatic Impairment:** Use with caution, dose reduction may be necessary.
* **Renal Impairment:** Use with caution, dose reduction may be necessary.
* **Elderly:** Elderly patients are more susceptible to anticholinergic adverse effects; initiate at a lower dose (e.g., 1 mg once daily) and titrate cautiously.
## Contraindications
* Known hypersensitivity to the drug.
* Angle-closure glaucoma.
* Myasthenia gravis.
* Megacolon or paralytic ileus.
* Untreated or symptomatic urinary retention.
## Adverse Effects
Common adverse effects include dry mouth, blurred vision, constipation, urinary retention, drowsiness, dizziness, confusion, and memory impairment. Less common but serious effects include tachycardia, increased intraocular pressure, and exacerbation of glaucoma.
## Key Drug Interactions
* **Other Anticholinergics:** Additive anticholinergic effects, increasing the risk of toxicity.
* **CNS Depressants (e.g., alcohol, sedatives, opioids):** Increased sedation and CNS depression.
* **MAO Inhibitors:** May potentiate anticholinergic effects.
* **Tricyclic Antidepressants:** Increased anticholinergic effects.
* **Potassium Chloride:** Risk of gastrointestinal lesions when taken concurrently with slow-release potassium chloride preparations.
## Monitoring
* Monitor for signs and symptoms of anticholinergic toxicity (e.g., dry mouth, constipation, urinary retention, blurred vision, confusion, hallucinations).
* Assess for improvement in Parkinsonian symptoms or extrapyramidal symptoms.
* Monitor for changes in cognitive function, especially in elderly patients.
* Consider intraocular pressure monitoring in patients at risk for glaucoma.
## Clinical Pearls
* Administer with meals or milk if gastrointestinal upset occurs.
* For constipation, recommend increased fluid and fiber intake, and consider stool softeners.
* Caution patients about operating machinery or driving until they know how the medication affects them due to potential for drowsiness and blurred vision.
* Gradual withdrawal is recommended to avoid rebound cholinergic symptoms.
