Mechanism of Fosinopril-Potassium citrate Interaction (Severity Level: Major)
Increased risk of hyperkalemia Click to Show/Hide Mechanism Graph
Drug Name		Fosinopril				Potassium citrate
Mechanism		Hyperkalemia				Hyperkalemia
Key Mechanism Factor 1
		Factor Name		Hyperkalemia
		Factor Description		Hyperkalemia is a condition in which the level of potassium in the blood is higher than normal. While mild cases may not produce symptoms, severe hyperkalemia can lead to fatal arrhythmias if left untreated.
Mechanism Description		Increased risk of hyperkalemia by the combination of Fosinopril and Potassium citrate

Recommended Action
Management		Caution is advised if ACE inhibitors must be used concurrently with potassium salts, particularly in patients with renal impairment, diabetes, old age, severe or worsening heart failure, dehydration, or concomitant therapy with other agents that increase serum potassium such as nonsteroidal anti-inflammatory drugs, beta-blockers, cyclosporine, heparin, tacrolimus, trimethoprim, and licorice. The combination should generally be avoided in these patients unless absolutely necessary and the benefits outweigh the potential risks. Serum potassium and renal function should be checked prior to initiating therapy and regularly thereafter. Patients should be given counseling on the appropriate levels of potassium and fluid intake, and advised to seek medical attention if they experience signs and symptoms of hyperkalemia such as nausea, vomiting, weakness, listlessness, tingling of the extremities, paralysis, confusion, weak pulse, and a slow or irregular heartbeat.
