# Walethmade bromide
## Overview
Walethmade bromide is a quaternary ammonium compound with anticholinergic properties.
## Primary Indications
Historically used as an antispasmodic for gastrointestinal disorders. Its use is limited due to lack of efficacy and availability of safer alternatives.
## Adult Dosing
Dosing is not well-established due to limited current use. Historically, doses ranged from 5 mg to 15 mg orally three times daily.
## Pediatric Dosing
No established pediatric dosing.
## Dose Adjustments
No specific dose adjustments for renal or hepatic impairment are established.
## Contraindications
- Known hypersensitivity to walethmade bromide.
- Glaucoma.
- Prostatic hypertrophy or bladder neck obstruction.
- Myasthenia gravis.
- Certain cardiac conditions (e.g., tachycardia, heart failure).
## Adverse Effects
Common anticholinergic side effects include: dry mouth, blurred vision, urinary retention, constipation, drowsiness, confusion, and tachycardia.
## Key Drug Interactions
- Other anticholinergic agents: Increased risk of anticholinergic side effects.
- Digoxin: May decrease digoxin absorption.
- MAO inhibitors: May potentiate anticholinergic effects.
- Antacids: May decrease absorption.
## Monitoring
- Monitor for signs and symptoms of anticholinergic toxicity.
- Assess for gastrointestinal relief if used for spasms.
## Clinical Pearls
- Walethmade bromide is rarely used in current clinical practice due to concerns about efficacy and safety.
- Consider alternative agents with better safety profiles for gastrointestinal indications.
- Quaternary ammonium structure limits central nervous system penetration, potentially leading to fewer CNS side effects compared to tertiary amine anticholinergics, but peripheral effects are still significant.
