Fesoterodine and Pyridostigmine: interaction and safety
This source-based reference is not a personal treatment recommendation. The relevance and management of an interaction depend on the exact products, route, dose and clinical situation.
Interaction mechanism
Antimuscarinics may oppose pyridostigmine muscarinic effects, while slower gastrointestinal transit may alter absorption.
Clinical significance and safety
Fesoterodine and Pyridostigmine: Some antimuscarinics, such as atropine, may be used deliberately by a specialist to manage adverse effects. Muscarinic opposition does not alone prove loss of the nicotinic muscle-strength benefit. Bladder antimuscarinics may have their own myasthenia-gravis contraindication. The clinician should assess muscle strength, bowel or bladder symptoms and toxicity together.
