Eplerenone (Inspra) and Ketamine Therapy | Tovani Health
Inspra (Eplerenone) — Selective aldosterone antagonist (heart failure, hypertension)
Verdict at Tovani Health
Fully compatible with KAP.
Eplerenone and ketamine have no clinically significant interaction. More selective for aldosterone receptor than spironolactone, so fewer hormonal side effects (no gynecomastia). Used in heart failure and resistant hypertension. Standard potassium monitoring is intrinsic.
If you take Inspra regularly and are considering at-home ketamine therapy, the combination is generally safe at therapeutic doses. This page covers the brief pharmacologic context and what we do at intake.
How Inspra interacts with ketamine
Eplerenone selectively antagonizes the mineralocorticoid receptor, reducing sodium reabsorption and potassium excretion. CYP3A4 substrate; strong CYP3A4 inhibitors (clarithromycin, ritonavir, itraconazole) substantially raise eplerenone levels — independent of KAP.
What we do at intake
Continue as prescribed. Maintain your usual potassium monitoring.
Bottom line
Eplerenone and ketamine have no clinically significant interaction. More selective for aldosterone receptor than spironolactone, so fewer hormonal side effects (no gynecomastia). Used in heart failure and resistant hypertension. Standard potassium monitoring is intrinsic.
