Diuretics

Diuretics are another class of drugs used to treat hypertension. These medications work by increasing the excretion of sodium and water from the body. By reducing the volume of blood circulating through the blood vessels, diuretics help lower blood pressure. They are often prescribed as a first-line treatment for hypertension and can be used in combination with other classes of drugs.

ACE Inhibitors and ARBs

ACE inhibitors (angiotensin-converting enzyme inhibitors) and ARBs (angiotensin receptor blockers) are two classes of drugs that work by blocking the action of certain hormones that constrict blood vessels. ACE inhibitors prevent the formation of angiotensin II, a hormone that causes blood vessels to narrow. ARBs, on the other hand, block the receptors that angiotensin II would normally bind to, preventing its effects. By inhibiting these constricting hormones, ACE inhibitors and ARBs help relax and widen the blood vessels, leading to lower blood pressure levels.

Beta Blockers

Beta blockers work by blocking the effects of adrenaline on the heart. Adrenaline is a hormone that increases heart rate and constricts blood vessels, both of which can lead to elevated blood pressure. By blocking the action of adrenaline, beta blockers reduce heart rate and blood pressure levels. They are commonly prescribed for individuals with hypertension, as well as for those with certain heart conditions.

By understanding how different classes of blood pressure drugs work, healthcare providers can tailor treatment plans based on individual patient needs. It’s important to note that these classes of drugs are not exhaustive, and other medications or combinations may be prescribed depending on the specific circumstances. Consulting with a healthcare provider is essential to determine the most suitable treatment approach for managing hypertension.

Formulation Options for Verapamil:

Verapamil, a medication commonly used to treat high blood pressure and certain heart conditions, is available in various formulations to cater to different patient needs.
