Abstract

Objective: The primary purpose of this research is to evaluate the risk of hyperkalemia in patients receiving co-trimoxazole. The secondary purpose is to detect the changes of potassium levels from baseline to 7, 14, 21, and 30 days, determine the association between co-trimoxazole dose and potassium level and examine the relationship between renal function and hyperkalemia. Methods: The approach was through retrospective observation of all patients treated with co-trimoxazole during Jan 2012 till Jan 2013. Key finding: There was no significant correlation between co-trimoxazole doses and hyperkalemia (29% in 480 mg, 31.6% in 960 and 19.4% in 1920 mg; p = 0.129) within each dose group, however, around 62% of hyperkalemia cases were associated with significant increase in serum creatinine (p = 0.00). The highest mean change of potassium level in once daily dosing was at “baseline–7 days” interval, while it was highest at 'baseline-30 days' interval in every other day dosing. However; none of the changes from baseline to 7, 14, 21 and 30 days was found to be significant. 40.9% of the studied patients were female and 59.1% were male and the mean age 54 ± 15 was significant higher in hyperkalemia group compare to 42.6 ± 20 in non hyperkalemia group (p = 0.001). Conclusion: Although many patients taking co-trimoxazoledeveloped Hyperkalemia, the effect of age, dose, renal function and the use of other concomitant medications can't be ignored.
