Abstract: 

Objective: This study aims to evaluate the practice and knowledge of Saudi pharmacists regarding chronopharmacology of antihypertensive drugs.

However, 35% did not know that blood pressure has two peaks; around 9:00 am and 7:00 pm, and one drop around 3:00 am. In addition, 24% of pharmacists did not know whether or not evening dose of nifedipine and GTN was more successful in decreasing the blood pressure as compared to the early hours in the morning.
