# Walethmade Bromide ## Overview Walethmade bromide is an anticholinergic agent. ## Primary Indications * Management of Parkinsonism, including drug-induced extrapyramidal symptoms. * Management of acute dystonic reactions. ## Adult Dosing * **Parkinsonism:** Typically 1 mg to 2 mg three to four times daily. Maximum dose is generally 6 mg four times daily. * **Drug-induced extrapyramidal symptoms:** Typically 1 mg to 2 mg as needed, may be repeated every few hours if necessary. * **Acute dystonic reactions:** 1 mg to 2 mg IM or IV. May be repeated every few hours if necessary. ## Pediatric Dosing Safety and efficacy in pediatric patients have not been established. Use is generally not recommended. ## Dose Adjustments * **Elderly:** May be more sensitive to anticholinergic effects; use with caution and consider lower starting doses. * **Hepatic Impairment:** No specific dose adjustments are established, but caution is advised due to potential for accumulation. * **Renal Impairment:** No specific dose adjustments are established, but caution is advised due to potential for accumulation. ## Contraindications * Known hypersensitivity to walethmade bromide. * Glaucoma (especially narrow-angle glaucoma). * Myasthenia gravis. * Obstructive uropathy. * Obstructive gastrointestinal disease. * Untreated tachycardia. ## Adverse Effects Common adverse effects include dry mouth, blurred vision, constipation, urinary retention, confusion, drowsiness, dizziness, and nervousness. Less common effects include increased heart rate, dilated pupils, and decreased sweating. ## Key Drug Interactions * **Other Anticholinergics:** Additive anticholinergic effects, increasing the risk of adverse events (e.g., amantadine, some antidepressants, antihistamines). * **CNS Depressants:** Increased sedation (e.g., benzodiazepines, opioids, sedating antihistamines). * **Potassium Chloride:** Concomitant use of slow-release potassium chloride formulations can lead to gastrointestinal lesions; monitor for signs of GI distress. ## Monitoring * Monitor for anticholinergic side effects (e.g., dry mouth, constipation, urinary retention, blurred vision, cognitive changes). * Assess for improvement in Parkinsonian symptoms or extrapyramidal symptoms. * Monitor for signs of acute dystonic reactions resolution. ## Clinical Pearls * Tolerance to some side effects, such as drowsiness and dry mouth, may develop over time. * Gradual withdrawal is recommended to avoid potential rebound symptoms. * Caution in patients with cardiac arrhythmias, prostatic hypertrophy, or hot weather due to risk of heat stroke. *** *This information is intended for healthcare professionals.
