Summary
Pyridostigmine raises acetylcholine levels while umeclidinium blocks muscarinic receptors, so they partly oppose each other. Muscarinic side effects of pyridostigmine may be masked, and the benefit on muscarinic-mediated symptoms may be reduced, though the nicotinic benefit in myasthenia is unaffected.
What this interaction means in plain words
Pyridostigmine and Umeclidinium have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Pyridostigmine belongs to Central Nervous System; Umeclidinium belongs to Respiratory.
Why it happens
Pharmacodynamic opposition between cholinesterase inhibition and muscarinic blockade.
What to do
Monitor myasthenia symptoms and for masked cholinergic effects, and adjust pyridostigmine dose according to clinical response.
