3. Amlodipine (Norvasc): This medicationis a calcium channel blocker. People usually take it once per day. Amlodipineis also a treatment option forangina.
4. Losartan (Cozaar):This medication is an angiotensin II receptor blocker. In most cases, the dose is once per day. Doctors also use this drug to decrease the risk ofstrokein people with an enlarged heart.

Some commonly prescribed Trusted Source American Heart Association Highly respected national organization Go to source classes ofantihypertensivemedications include:

• ACE inhibitors: These drugs block an enzyme to reduce the body’s amount of angiotensin. Having less angiotensin in the body helps the blood vessels relax. Some common side effects of ACE inhibitors includea rashand a drycough. Examples include captopril, enalapril, and lisinopril.
• Angiotensin II receptor blockers: This class directly blocks angiotensin to relax the blood vessels. Common side effects includedizzinessand lightheadedness, especially when standing up from a seated position. Examples include losartan and valsartan.
• Alpha-blockers:This class relaxes the blood vessels. The drugs can also relax the muscles in organs, such as the bladder and prostate gland. Dizziness, especially when rising, is a common side effect.
• Beta-blockers: These drugs block the effects of adrenaline. This lowers blood pressure by decreasing your heart rate and the force of each beat. Examples include atenolol, metoprolol, and propranolol.
• Calcium channel blockers: This class relaxes the blood vessels and decreases the heart rate. Possible side effects include heartpalpitations,ankle swelling,constipation,headaches, and dizziness. Examples include amlodipine and felodipine.
• Central agonists: This class reduces the heart rate and relaxes the blood vessels by affecting certain nerve signals from the brain. Common side effects include dry mouth, constipation, and drowsiness. Examples include clonidine and guanfacine.
• Diuretics: These drugs work by increasing the amount of fluid the body eliminates through urination. Many people call diuretics “water pills.” By reducing your body’s volume of blood, the pressure inside the arteries decreases.
