Drug Guide
Sofpironium Bromide
Classification
Therapeutic: Topical Anticholinergic (used for hyperhidrosis)
Pharmacological: Muscarinic receptor antagonist
FDA Approved Indications
- Treatment of primary axillary hyperhidrosis (excessive underarm sweating)
Mechanism of Action
Sofpironium bromide inhibits muscarinic receptors in the eccrine sweat glands, reducing sweating.
Dosage and Administration
Adult: Apply a thin layer to affected areas once daily, as directed by the healthcare provider.
Pediatric: Use in children has not been established; consult specific guidelines.
Geriatric: Adjustments not typically required, but monitor for anticholinergic side effects.
Renal Impairment: Use with caution; no specific adjustments established.
Hepatic Impairment: Use with caution; limited data available.
Pharmacokinetics
Absorption: Minimal systemic absorption with topical application.
Distribution: Primarily localized; systemic levels are low.
Metabolism: Metabolized locally; systemic metabolism data limited.
Excretion: Excreted mainly unchanged in sweat and possibly via renal routes in minimal amounts.
Half Life: Data not widely published; likely short due to minimal systemic absorption.
Contraindications
- Hypersensitivity to sofironium bromide or other anticholinergic agents.
Precautions
- Use with caution in patients with urinary retention, close-angle glaucoma, or at risk for these conditions.
- Avoid contact with eyes.
Adverse Reactions - Common
- Dry skin or skin irritation at application site (Common)
- Eyes irritation if contact occurs (Uncommon)
Adverse Reactions - Serious
- Eye pain or visual disturbances (Rare)
- Allergic skin reactions (Rare)
Drug-Drug Interactions
- Little known systemic interactions due to minimal absorption.
Drug-Food Interactions
- No significant interactions known.
Drug-Herb Interactions
- No data available.
Nursing Implications
Assessment: Assess areas of hyperhidrosis before and after treatment.
Diagnoses:
- Excessive skin moisture
- Potential for skin irritation
Implementation: Apply as directed, with clean, dry skin.
Evaluation: Monitor reduction in sweating and skin tolerance.
Patient/Family Teaching
- Apply only to affected areas as directed.
- Avoid contact with eyes.
- Report any skin irritation or eye discomfort.
- Use regularly for optimal results.
Special Considerations
Black Box Warnings:
- No black box warnings reported.
Genetic Factors: No specific genetic considerations.
Lab Test Interference: No known interference with lab tests.
Overdose Management
Signs/Symptoms: Potential systemic anticholinergic effects such as dry mouth, urinary retention, blurred vision, tachycardia.
Treatment: Discontinue use; symptomatic and supportive care. Specific antidote is not established.
Storage and Handling
Storage: Store at room temperature, away from moisture and light.
Stability: Stable under recommended storage conditions.
