Determining the interaction of Carospir Suspension and Lanoxicaps and the possibility of their joint administration.

Check result:
Carospir Suspension <> Lanoxicaps
Relevance: 21.08.2022 Reviewer: Shkutko P.M., M.D., in

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Consumer:

Consumer information for this minor interaction is not currently available. Some minor drug interactions may not be clinically relevant in all patients. Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.

Professional:

Spironolactone may reduce the tubular secretion of digoxin. Plasma clearance of digoxin may be decreased, and plasma levels may increase. Also, limited data indicate that spironolactone may have a negative inotropic side effect. Finally, spironolactone may interfere with some digoxin radioimmunoassays, and digoxin concentrations may be overestimated. During coadministration, the patient should be monitored for signs and symptoms of digoxin toxicity, levels should be checked when necessary, and the clinician should keep in mind the possibility that digoxin levels may falsely appear to be elevated. Patients should be advised to notify their physician if they experience nausea, anorexia, visual changes, or irregular heartbeats.
