title: Lansoprazole potentiates vecuronium paralysis.
abstract: The effect of lansoprazole, a newer second generation proton pump inhibitor, on vecuronium induced muscle paralysis was evaluated. Fifty adult patients comprising grade I (normal healthy patient) and grade II (patient with a mild systemic disease) as classified by the American Society of Anesthesiologists were randomly allocated into two different groups each consisting of 25 patients. Group I (control) did not receive lansoprazole and group II (study) received 30 mg lansoprazole in the night before operation. There was no statistically significant difference (p > 0.05) in the time required for complete paralysis between group I (215.7 +/- 15.19 seconds) and group II (197.5 +/- 14.13 seconds). However, the duration of paralysis was significantly different (p < 0.05) between group I (32.7 +/- 8.7 minutes) and group II (43.9 +/- 9.3 minutes). It was concluded that there is a potential for interactions and one should carefully and closely monitor the patients to prevent prolonged paralysis in patients receiving lansoprazole, as a pre-anaesthetic medication.
