Possible Interaction: Potassium and Terbutaline

“RESULTS Te butaline si gnificantly reduced plasma pot assium co ncentrations and significantly increased heart rates during the time course of the study (P < 0.001, repeated-measures analysis of variance).”

“We conclude that ritodrine and terbutaline induce profound hypokalemia by stimulating cellular potassium uptake and both drugs cause significant renal sodium and fluid retention and cardiac arrhythmias.”

“Administration of the beta2 adrenergic agonists fenoterol, salbutamol and terbutaline to volunteers significantly reduced plasma potassium concentration in a double-blind crossover study.”

“Fenoterol, salbutamol and terbutaline all significantly decreased plasma potassium when compared to saline; however, the magnitude and duration of this effect differed between the active agents.”

“Additional responses that can be readily characterized with such models include muscular contraction from pyridostigmine, diuresis from furosemide, bronchodilation from terbutaline, prolactin secretion after Cimetidine, and potassium suppression by terbutaline.”
