# Walethmade bromide
## Overview
Walethmade bromide is a synthetic anticholinergic and antispasmodic agent. It is primarily used to reduce smooth muscle spasms.
## Primary Indications
* Gastrointestinal spasms
* Biliary colic
* Renal colic
* Ureteral spasms
## Adult Dosing
* **Oral:** 10 mg to 20 mg three times daily. Maximum daily dose is typically 60 mg.
* **Intramuscular/Intravenous:** 10 mg to 20 mg every 4 to 6 hours as needed. Higher doses may be administered in acute settings under strict medical supervision, but precise maximums vary and should follow local protocol.
## Pediatric Dosing
Dosing in pediatric patients is not well-established and should be determined by a specialist based on the child's specific condition and weight, following local institutional guidelines.
## Dose Adjustments
* **Renal Impairment:** Use with caution. No specific dose adjustment guidelines are universally established; monitor for increased anticholinergic effects.
* **Hepatic Impairment:** Use with caution. No specific dose adjustment guidelines are universally established; monitor for increased anticholinergic effects.
* **Elderly:** Use with caution due to increased susceptibility to anticholinergic side effects. Lower doses may be more appropriate.
## Contraindications
* Hypersensitivity to walethmade bromide or any component of the formulation.
* Angle-closure glaucoma.
* Myasthenia gravis.
* Ileus or toxic megacolon.
* Severe ulcerative colitis.
* Prostatic hyperplasia with urinary retention.
* Tachyarrhythmias.
## Adverse Effects
Common adverse effects include dry mouth, blurred vision, constipation, urinary retention, drowsiness, dizziness, and tachycardia. Less common but serious effects can include confusion, hallucinations, and increased intraocular pressure.
## Key Drug Interactions
* **Anticholinergic agents:** Additive anticholinergic effects (e.g., atropine, scopolamine, certain antihistamines, tricyclic antidepressants).
* **MAO inhibitors:** May potentiate anticholinergic effects.
* **Potassium chloride:** Concurrent use, especially in slow-release formulations, can increase the risk of gastrointestinal ulceration and bleeding.
## Monitoring
* Monitor for efficacy in reducing spasms.
* Monitor for anticholinergic side effects (e.g., dry mouth, blurred vision, urinary retention, constipation, cognitive changes).
* Monitor vital signs, particularly heart rate, in patients receiving parenteral administration or those at risk for tachycardia.
## Clinical Pearls
* Walethmade bromide should be used cautiously in patients with conditions that can be exacerbated by anticholinergic effects.
* Parenteral administration may be preferred for rapid relief of severe colic.
* Adequate hydration and fiber intake can help mitigate constipation.
