β-Adrenoblockers - increased action of pipecuronium. Aminoglycosides, vancomycin, capreomycin, lincomycin, massive infusions of citrated blood, local (including procaine and lidocaine) and general anesthetics, polymyxins, tetracyclines, trimetafan, ureidopenicillins - additive muscle relaxant effect.
Anesthetics common (halothane, isoflurane, methoxyflurane, trichlorethylene, chloroform, cyclopropane, enflurane, diethyl ether) - additive muscle relaxant effect.
Antimiasthenic drugs, calcium salts, and eudrophonia - decreased myorelaxing activity.
Aprotinin - the risk of apnea.
Blockers of slow calcium channels, ganglion blockers, lidocaine, procainamide, magnesium salts, quinidine - Increased neuromuscular blockade.
Botulinum toxin A - strengthening neuromuscular blockade.
Muscle relaxants, depolarizing - enhancement of muscle relaxation, if prescribed before the administration of nondepolarizing muscle relaxants.
Opioid analgesics are an additive depressive effect on respiratory function, a reduction in muscle rigidity caused by fentanyl and its derivatives, an additive depressive effect on hemodynamics, an additive effect on the release of histamine.
Anticonvulsants (carbamazepine, phenytoin), metoclopramide - Increase the duration of action of pipecuronium.
Means that reduce the concentration of potassium in the plasma (amphotericin B, bumetanide, glucocorticoids, especially with high mineralocorticoid activity, inhibitors of carbonic anhydrase, indapamide, thiazide diuretics, chronic use of ACTH, furosemide, ethacrynic acid) - increased muscle relaxancy.
