Possible Interaction: Captopril and Potassium

supplement:

Potassium

Research Papers that Mention the Interaction

During combined Captopril treatments (also with a diuretic) two patients had so severe hypokalaemia that they needed potassium substitution or administration of a potassium-saving diuretic.

Captopril also suppressed the augmentation of P450c18 mRNA observed with potassium supplementation but had no effect on P450scc mRNA levels.

Finally, captopril inhibited potassium induction of aldosterone synthase P-450 mRNA levels despite the presence of low plasma renin activity in the potassium-treated rats.

It … that captopril pretreatment significantly reduced the magnitude of … secretory response to increments in potassium of 0.5 to 6.0 mM, from a baseline potassium concentration of 3.5 mM. Responses … the lowest increment in potassium, 0.5 and 1.0 mM, were virtually abolished by captopril treatment.
