Hypertension yaani high BP ek silent killer hai—symptoms kam dikhte hain but damage zyada karta hai. Isko control karne ke liye use hote hain antihypertensive drugs. Sabse pehle—Diuretics. Yeh body se extra salt aur water nikalte hain, jisse BP kam hota hai. Next—Beta blockers. Yeh heart rate slow karte hain, so pressure automatically reduce hota hai. ACE inhibitors—jaise Enalapril. Yeh blood vessels ko relax karte hain. Calcium channel blockers bhi vessels ko dilate karte hain.
