Theoretically, combining these casein peptides with antihypertensive drugs might increase the risk of hypotension.
Clinical research shows that some casein peptides, including the lactotripeptides isoleucine-proline-proline (IPP) and valine-proline-proline (VPP), can modestly reduce blood pressure in patients with hypertension.

Acetazolamide Overview
-
Acetazolamide is used to treat glaucoma, a condition in which increased pressure in the eye can lead to gradual loss of vision. Acetazolamide decreases the pressure in the eye. Acetazolamide is also used to reduce the severity and duration of symptoms (upset stomach, headache, shortness of breath, dizziness, drowsiness, and fatigue) of altitude (mountain) sickness. Acetazolamide is used with other medicines to reduce edema (excess fluid retention) and to help control seizures in certain types of epilepsy.
