Acetazolamide and theophylline are respiratory stimulants. They are indicated in central sleep apnea only to stimulate the respiratory drive. They are not indicated in obstructive sleep apnea.
Thanks for the guidance

Yes if you think about it without even referring to a book, acetazolamide basically is a carbonic anhydrase inhibitor that causes metabolic acidosis. In effect: respiratory alkalosis and respiratory stimulation. That's probably why it's given in sleep apnea.
Thanks for the above post!
