Final answer:
The two dihydropyridine calcium channel blockers (CCBs) are amlodipine (Norvasc, Lotrel) and nisoldipine (Sular). They are used to treat hypertension and angina by causing vasodilation and lowering blood pressure.
Step-by-step explanation:
The Two Dihydropyridine Calcium Channel Blockers (CCBs)
The dihydropyridine class of calcium channel blockers includes several medications, but the two specifically asked about are amlodipine and nisoldipine. These drugs are commonly used to treat conditions like hypertension and angina. Amlodipine is known by the brand names Norvasc and Lotrel, while nisoldipine is marketed as Sular. Both work by blocking calcium channels in vascular smooth muscle, leading to vasodilation and reduced blood pressure.
