Commonly Prescribed Blood Pressure Medications – Overview of Calan and Other Options

Calan: An Overview

Calan is a widely used medication that belongs to a class of drugs known as calcium channel blockers. It is primarily prescribed for the treatment of high blood pressure, also known as hypertension. This medication works by relaxing the blood vessels, allowing for smoother blood flow and reducing the pressure on the arterial walls.

How does Calan work?

Calan inhibits the influx of calcium ions into the smooth muscle cells of the blood vessels. By blocking the calcium channels, it prevents the muscle cells from contracting too strongly, thereby promoting relaxation and dilation of the blood vessels. This mechanism of action leads to a decrease in blood pressure levels.

Common uses of Calan

Aside from its effectiveness in treating hypertension, Calan is also prescribed for other medical conditions. These include:

  1. Angina: Calan helps relieve chest pain by dilating the coronary arteries and improving blood flow to the heart.
  2. Arrhythmia: This medication can normalize irregular heart rhythms, such as atrial fibrillation or atrial flutter, by regulating the electrical conductivity of the heart.
  3. Migraine prevention: Calan is sometimes used to prevent migraines, although the exact mechanism for its effectiveness in migraine management is not fully understood.

Forms and dosage

Calan is available in various forms, including immediate-release tablets, extended-release tablets, and oral suspension. The dosage will depend on the specific condition being treated and the patient’s response to the medication.

For hypertension, the usual starting dose of immediate-release Calan is 80 mg orally, three times a day. The dosage may be increased gradually if necessary. Extended-release Calan tablets are typically started at 120-240 mg once daily and can be increased based on individual response.

It is crucial to follow the prescribing doctor’s instructions and consult with them regarding any dosage adjustments or concerns.

Possible side effects of Calan

As with any medication, Calan may cause some side effects in certain individuals. Common side effects can include dizziness, constipation, headache, and nausea. These symptoms are usually mild and transient, but it is important to report any persistent or severe adverse effects to the prescribing healthcare professional.

Rare but serious side effects may include an allergic reaction, severe dizziness or fainting, shortness of breath, rapid or irregular heartbeat, and swelling of the hands, feet, or lower legs. If any of these occur, immediate medical attention should be sought.

Conclusion

Calan is a widely prescribed calcium channel blocker that effectively treats hypertension, angina, arrhythmia, and migraines. By relaxing the blood vessels and reducing arterial pressure, it plays a crucial role in managing these conditions. However, as with any medication, it is essential to use Calan under the supervision of a healthcare professional and adhere to the prescribed dosage and guidelines.

Commonly Prescribed Blood Pressure Medications

Blood pressure medications are commonly prescribed to help manage and control high blood pressure, also known as hypertension. These medications work by reducing the pressure of blood against the walls of blood vessels, thereby decreasing the risk of heart disease, stroke, and other complications associated with high blood pressure. One of the commonly prescribed blood pressure medications is Calan.

1. Calan (Verapamil)

Calan, also known as Verapamil, is a medication that belongs to the calcium channel blocker drug class. It works by relaxing and widening the blood vessels, allowing blood to flow more easily and reducing the workload on the heart.

Benefits of Calan:

  • Effective in lowering blood pressure
  • Reduces the frequency and severity of chest pain (angina)
  • Helps manage certain types of irregular heartbeat (arrhythmias)

Calan is available in different forms, including immediate-release tablets, extended-release tablets, and sustained-release capsules. The appropriate form and dosage of Calan may vary depending on the individual’s condition and response to the medication.

2. Other Common Blood Pressure Medications

Aside from Calan, there are several other blood pressure medications commonly prescribed by healthcare professionals. These medications may be used alone or in combination with other drugs to achieve optimal blood pressure control.

2.1 ACE Inhibitors

Angiotensin-converting enzyme (ACE) inhibitors are a type of medication that blocks the production of a hormone called angiotensin II, which narrows blood vessels. By inhibiting angiotensin II, ACE inhibitors help relax and widen blood vessels, resulting in lower blood pressure. Commonly prescribed ACE inhibitors include:

  • Lisinopril
  • Enalapril
  • Ramipril

2.2 ARBs

Angiotensin II receptor blockers (ARBs) are another class of blood pressure medications. Instead of blocking the production of angiotensin II like ACE inhibitors, ARBs work by blocking the receptors that angiotensin II binds to. This action helps relax blood vessels and lowers blood pressure. Examples of commonly prescribed ARBs include:

  • Losartan
  • Valsartan
  • Telmisartan

2.3 Diuretics

Diuretics, often referred to as “water pills,” are medications that promote the elimination of excess salt and water from the body through increased urine production. By reducing fluid volume in the blood vessels, diuretics help lower blood pressure. Commonly prescribed diuretics include:

  • Hydrochlorothiazide
  • Chlorthalidone
  • Furosemide

2.4 Beta Blockers

Beta blockers are medications that block the effects of adrenaline, a hormone that increases heart rate and blood pressure. By blocking these effects, beta blockers help slow down the heart rate and lower blood pressure. Commonly prescribed beta blockers include:

  • Metoprolol
  • Atenolol
  • Propranolol

It’s important to note that the choice of blood pressure medication depends on multiple factors, including the individual’s overall health, any underlying medical conditions, and potential drug interactions. Therefore, it is crucial to consult a healthcare professional before starting or changing any blood pressure medication regimen.
