Summary
Dichlorphenamide, a carbonic anhydrase inhibitor, causes potassium loss and hyperchloremic metabolic acidosis. Perioperative hypokalemia and acidosis may increase the risk of arrhythmia and complicate anesthetic management.
What this interaction means in plain words
Desflurane and Dichlorphenamide 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.
Desflurane belongs to Central Nervous System; Dichlorphenamide belongs to Miscellaneous.
Why it happens
Carbonic anhydrase inhibition causes renal bicarbonate and potassium wasting, producing electrolyte and acid-base disturbances that add to perioperative stresses.
What to do
Check serum potassium and bicarbonate before surgery and correct abnormalities. Monitor ECG, electrolytes and acid-base status during and after anesthesia.
