Short General Description of the Drug Calan
Calan, also known by its generic name verapamil, is a medication commonly prescribed for the management of hypertension or high blood pressure. It belongs to the class of drugs called calcium channel blockers, which work by relaxing and widening the blood vessels, allowing for smoother blood flow and reducing the strain on the heart.
This medication is available in two main forms: Calan SR, which stands for sustained-release, and Calan 80mg, which refers to the specific dosage strength of 80 milligrams. Both forms contain verapamil as the active ingredient and are used to treat hypertension, angina, and certain heart rhythm disorders.
It’s important to note that Calan should only be taken under the guidance and prescription of a healthcare professional, as they will determine the appropriate dosage and monitor its effectiveness for each individual.
How Different Classes of Blood Pressure Drugs Work in Managing Hypertension
Hypertension, commonly known as high blood pressure, affects millions of people worldwide and is a significant risk factor for cardiovascular diseases. Fortunately, there are various classes of drugs available to effectively manage this condition. Understanding how different classes of blood pressure drugs work can aid in selecting the most suitable treatment option for individuals.
1. Angiotensin-Converting Enzyme (ACE) Inhibitors
ACE inhibitors, such as Lisinopril and Enalapril, work by blocking the action of an enzyme called angiotensin-converting enzyme. This enzyme plays a crucial role in the production of angiotensin II, a hormone that constricts blood vessels and raises blood pressure. By inhibiting this enzyme, ACE inhibitors help relax blood vessels, reduce fluid retention, and lower blood pressure.
2. Angiotensin Receptor Blockers (ARBs)
ARBs, including Losartan and Valsartan, work differently than ACE inhibitors. Instead of blocking the production of angiotensin II like ACE inhibitors, ARBs directly block the receptors to which angiotensin II binds. By doing so, ARBs prevent angiotensin II from exerting its effects, resulting in blood vessel relaxation and lowered blood pressure.
3. Calcium Channel Blockers
Calcium Channel Blockers, such as Verapamil and Amlodipine, work by blocking calcium channels in the cells of blood vessels. These channels are responsible for regulating the amount of calcium that enters the cells, which is necessary for blood vessels to contract. By blocking calcium entry, calcium channel blockers cause blood vessels to relax, reducing blood pressure.
4. Diuretics
Diuretics, such as Hydrochlorothiazide and Furosemide, increase the excretion of sodium and water from the body through the urine. This action reduces fluid buildup in blood vessels, leading to a decrease in blood volume and lower blood pressure. Diuretics are often used as a first-line treatment for hypertension.
5. Beta-Blockers
Beta-blockers, including Atenolol and Metoprolol, work by blocking the beta receptors on cells in the heart and blood vessels, reducing the effects of stress hormones like adrenaline. By doing so, beta-blockers decrease heart rate and cardiac output, relax blood vessels, and lower blood pressure.
6. Alpha-Blockers
Alpha-blockers, such as Prazosin and Doxazosin, block the alpha receptors located on the smooth muscles of blood vessels, allowing them to relax and widen. This relaxation helps to lower blood pressure and reduce resistance to blood flow.
7. Combined Alpha- and Beta-Blockers
Combined alpha- and beta-blockers, such as Carvedilol and Labetalol, block both alpha and beta receptors, offering a dual mechanism for reducing blood pressure. They not only decrease heart rate and cardiac output but also relax blood vessels, leading to effective blood pressure control.
Choosing the right class of blood pressure medication depends on several factors, including the individual’s specific needs, medical history, and potential side effects. It is crucial to consult with a healthcare professional to determine the most suitable drug or combination of drugs for managing hypertension effectively.
Drug Interactions with Common Over-the-Counter Medications or Nutritional Supplements
When taking any medication, it is important to be aware of potential drug interactions that can occur. Verapamil, commonly sold under the brand name Calan, is no exception.

The Nomenclature of Blood Pressure Medications
When it comes to managing hypertension, understanding the different classes of blood pressure medications is crucial. These medications, which target different mechanisms in the body, play a vital role in lowering high blood pressure and reducing the risk of complications associated with hypertension.
Class 1: Angiotensin-Converting Enzyme (ACE) Inhibitors
ACE inhibitors, such as Lisinopril and Enalapril, work by blocking the production of a hormone called angiotensin II. Angiotensin II causes blood vessels to constrict and triggers the release of another hormone called aldosterone, which promotes salt and fluid retention. By inhibiting this hormone, ACE inhibitors relax blood vessels, reducing blood pressure and improving blood flow.
Class 2: Angiotensin Receptor Blockers (ARBs)
ARBs, like Losartan and Valsartan, work by blocking the action of angiotensin II at specific receptors. By doing so, they prevent the constriction of blood vessels and the release of aldosterone. ARBs are often prescribed for patients who cannot tolerate ACE inhibitors or experience side effects.
Class 3: Calcium Channel Blockers (CCBs)
CCBs, such as Amlodipine and Diltiazem, work by blocking the entry of calcium into the muscle cells of blood vessels and the heart. Without calcium, the muscle cells relax, reducing the force of contractions and enabling blood vessels to dilate. This leads to lower blood pressure and improved blood flow.
Class 4: Beta-Blockers
Beta-blockers, like Metoprolol and Propranolol, work by blocking the effects of adrenaline and noradrenaline on the heart and blood vessels. By doing so, they reduce the heart rate, decrease the force of contractions, and relax blood vessels. This results in reduced blood pressure and a lower workload for the heart.
Class 5: Diuretics
Diuretics, such as Hydrochlorothiazide and Chlorothiazide, work by increasing the excretion of salt and water from the body through urine. By reducing fluid volume, diuretics decrease the amount of fluid that the heart needs to pump, leading to lower blood pressure. They are often used as initial therapy or in combination with other blood pressure medications.
It’s important to note that these classifications are not exhaustive and that there are other sub-classes and combination medications available. The choice of medication depends on various factors, including the patient’s overall health, response to treatment, and potential side effects.
Consulting with a healthcare professional is essential to determine the most appropriate blood pressure medication for individual cases. They will consider factors such as coexisting medical conditions, potential drug interactions, and overall treatment goals.
