Function&Application
1. It can inhibit the activity of cholinesterase in plasma, make the local anesthetics of ester group hydrolyze slowly in vivo, and easy to cause toxic reaction.Therefore, it is advisable to use an amide local anesthetic during the use of this drug.
2. Aminoglycoside antibiotics, capreomycin, lincomycin, polymyxin, lidocaine intravenous injection or quinine intramuscular injection can all act on neuromuscular joint and weaken skeletal muscle tone. Therefore, different degrees of antagonism can be generated in the action of this drug.
3. Can weaken the muscle relaxation effect of ether, enflurane, isoflurane, methoxyflurane, cyclopropane and other inhaled anesthetics.
4. The antihypertensive drugs (such as guanidine, megammine and mifen) that block sympathetic ganglion can weaken the effect of this drug.
5. Even weak anti-muscarinoid drugs (such as procaine and quinidine, etc.) can weaken the effect of this drug on myasthenia gravis, so it is not suitable for use.
6. Atropine ACTS on m-cholinergic receptor, which can reduce the adverse reactions of the cholinesterase inhibitory drug overdose. Therefore, when this drug is used to antagonize non-depolarizing muscle relaxants, it can be used together with atropine.
