Interactions of calcium channel blockers with non-depolarising muscle relaxants in vitro.

The effects of two calcium channel blockers (verapamil and nicardipine) on indirectly elicited muscle twitch and possible interactions between these drugs and non-depolarising muscle relaxants (vecuronium, atracurium, pancuronium) were investigated using isolated rat phrenic nerve-hemidiaphragm preparations. Both verapamil 10(-5) M and nicardipine 10(-6) M caused significant depression of twitch amplitude. Verapamil significantly increased vecuronium- and atracurium-induced neuromuscular block, but not that produced by pancuronium. Nicardipine potentiated atracurium-induced neuromuscular block but had no effect on pancuronium- and vecuronium-induced twitch depression. Neostigmine 10(-6) M did not produce any significant changes in the maximal recovery of twitch depression induced with calcium channel blockers and muscle relaxants combinations; also, neostigmine had no effect on maximal recovery time of twitch depression.

A case of acute poisoning due to organophosphate insecticide.

A case of acute severe organophosphate poisoning by deliberate self administration is reported. The patient required intensive therapy for 30 days. Unusual features of the case were the avoidance of atropine, because of the high risk of ventricular fibrillation, and the ineffectiveness of pralidoxime.
