Summary
Echothiophate is an irreversible cholinesterase inhibitor that increases acetylcholine activity, while scopolamine blocks muscarinic receptors. Scopolamine can counteract the miotic and intraocular pressure-lowering effects of echothiophate.
What this interaction means in plain words
Echothiophate iodide and Scopolamine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Pharmacodynamic antagonism: muscarinic blockade opposes the effects of cholinesterase inhibition.
What to do
Monitor intraocular pressure and pupil response, and avoid the combination if possible. Reassess glaucoma therapy if control worsens.
