Ketamine and Pindolol: moderate interaction.
Last updated
For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Summary
Ketamine usually raises heart rate and blood pressure through sympathetic stimulation, and a beta-blocker such as pindolol can blunt this response. In catecholamine-depleted or hemodynamically fragile patients ketamine may act as a direct myocardial depressant, so hypotension or bradycardia may occur.
What this interaction means in plain words
Ketamine and Pindolol can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Pindolol's beta-adrenergic blockade opposes ketamine's sympathomimetic cardiovascular stimulation, unmasking its direct negative inotropic effects.
What to do
Monitor blood pressure and heart rate continuously during ketamine administration and titrate the dose slowly. Have vasopressors available in patients with limited cardiovascular reserve.
What to ask your pharmacist

- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
