Ak-Dilate is part of the Alpha-1 Agonists class and treats Pupil Dilation. Alpha-1 agonists are used to treat a variety of conditions such as hypotension, nasal congestion, droopy eyelid, and rosacea. They work by tightening your blood vessels to raise your blood pressure, reducing inflammation in the nasal passages, and causing the skin to become less red. Ak-Dilate is only available as a brand name drug.
