Funny-channel (If) inhibitor (heart rate reduction; HF, angina)Reviewed May 19, 2026

Ivabradine (Corlanor) and Ketamine Therapy | Tovani Health

Corlanor (Ivabradine)Funny-channel (If) inhibitor (heart rate reduction; HF, angina)

Verdict at Tovani Health

Compatible; CYP3A4 inhibitors meaningfully raise ivabradine levels — flag for KAP patients on those.

Ivabradine and ketamine are compatible. Ivabradine selectively lowers heart rate without affecting BP or contractility, used in heart failure and chronic angina. The relevant flag isn't a KAP interaction — it's that strong CYP3A4 inhibitors (clarithromycin, Paxlovid, itraconazole) substantially raise ivabradine levels and can cause bradycardia. Patients prescribed any of those alongside ivabradine need careful drug review.

If you take Corlanor regularly and are considering at-home ketamine therapy, the combination is safe with monitoring or dose adjustment. This page covers the brief pharmacologic context and what we do at intake.

How Corlanor interacts with ketamine

Ivabradine inhibits the cardiac pacemaker funny current (If) at the sinoatrial node, lowering heart rate selectively. Major CYP3A4 substrate. No direct ketamine interaction.

What we do at intake

Disclose dose and indication. Tell us about all medications, especially any CYP3A4 inhibitors.
