Summary

Ketamine usually raises blood pressure and heart rate through sympathetic stimulation, but in catecholamine-depleted or beta-blocked patients it can act as a direct myocardial depressant. With sotalol this may cause hypotension or reduced cardiac output.

What this interaction means in plain words

Ketamine and Sotalol 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.

Ketamine belongs to Central Nervous System; Sotalol belongs to Cardiovascular.

Evidence level: Low

Why it happens

Beta-blockade limits the compensatory sympathetic response, unmasking ketamine's direct negative inotropic effect.

What to do

Monitor blood pressure, heart rate and ECG during induction and titrate ketamine cautiously. Have fluids and vasopressors ready.

What to ask your pharmacist

  • Should I take them at different times of day?
