“An increase in acetylcholine concentration caused by neostigmine and calcium may enhance the use-dependent ion channel block of the nicotinic acetylcholine receptor caused by clindamycin.”
“Neostigmine and calcium antagonized the neuromuscular blockade caused by gentamicin, but augmented that caused by clindamycin.”
“The effective concentration of 50% maximal effect (EC50) values of clindamycin for tetanic fade in the presence of 5 mM calcium or 250 nM neostigmine were reduced by approximately 52%.ConclusionClindamycin and gentamicin interfere with neuromuscular transmission and cause tetanic fade.”
