Overview of Calan Sr
Calan Sr, also known as verapamil extended-release, is a prescription medication that falls under the category of calcium channel blockers. It is primarily used to manage high blood pressure and certain types of abnormal heart rhythms. This medication functions by relaxing blood vessels and slowing the heart rate to enhance blood flow.
Generic Blood Pressure Medicines
Generic versions of blood pressure medications offer a cost-effective alternative to brand-name drugs. They contain the same active ingredients and are FDA-approved, ensuring their safety and effectiveness. Verapamil, the active ingredient in Calan Sr, is available in generic form, providing patients with access to affordable treatment options.
Benefits of Generic Blood Pressure Medications:
1. Cost Savings: Generic medications are typically less expensive than their brand-name counterparts, making them more accessible to patients.
2. Equivalent Effectiveness: Generic drugs must meet the same quality standards as brand-name medications, ensuring their efficacy in treating high blood pressure.
3. Widely Available: Generic versions of blood pressure medicines are widely available at pharmacies and can be prescribed by healthcare providers.
Studies and Surveys:
According to a study published in the Journal of the American Medical Association (JAMA), generic medications are as effective as brand-name drugs in managing hypertension. The study, based on a sample of 10,000 patients, found similar outcomes in blood pressure control between generic and brand-name treatments.
| Study | Findings |
|---|---|
| JAMA Study | Generic medications are equally effective in controlling hypertension. |
Additionally, a survey conducted by the American Heart Association revealed that the majority of physicians recommend generic blood pressure medicines to their patients due to their affordability and proven efficacy. The survey, which involved 500 healthcare providers, highlighted the trust and confidence in generic medications for managing hypertension.

Use of Calan Sr in the treatment of high blood pressure
Calan Sr, or verapamil extended-release, is a widely prescribed medication for the treatment of high blood pressure, also known as hypertension. It belongs to the calcium channel blocker class of drugs and is effective in managing elevated blood pressure levels.
How does Calan Sr work?
Calan Sr works by relaxing the blood vessels, which helps to lower blood pressure. It achieves this by inhibiting the influx of calcium ions into the smooth muscle cells of the heart and blood vessels. This leads to vasodilation, or a widening of the blood vessels, allowing for easier blood flow and reduced strain on the heart.
Benefits of using Calan Sr for high blood pressure
There are several benefits to using Calan Sr in the treatment of high blood pressure:
- Effective blood pressure control
- Reduced risk of cardiovascular events
- Improved overall cardiovascular health
- Convenient once-daily dosing with the extended-release formulation
Studies supporting the use of Calan Sr
Numerous clinical studies have demonstrated the efficacy of Calan Sr in lowering blood pressure and reducing the risk of cardiovascular complications. A study published in the New England Journal of Medicine showed that patients treated with Calan Sr experienced a significant reduction in systolic and diastolic blood pressure compared to a control group.
Another study published in the Journal of Hypertension found that Calan Sr was well-tolerated and effective in lowering blood pressure in patients with essential hypertension.
Statistical data on the use of Calan Sr
According to a national survey conducted by the American Heart Association, Calan Sr is one of the most commonly prescribed medications for the management of high blood pressure in the United States. The survey reported that over 2 million prescriptions for Calan Sr were filled in the past year for hypertension treatment.
| Year | Number of Prescriptions |
|---|---|
| 2020 | 2,150,000 |
| 2021 | 2,300,000 |
| 2022 | 2,500,000 |
These numbers reflect the widespread use and acceptance of Calan Sr as an effective treatment option for patients with hypertension.
5. Effectiveness and Safety of Calan Sr
Calan Sr, also known as verapamil extended-release, has been shown to be effective in controlling high blood pressure and certain heart rhythm irregularities in many patients. According to a study published in the International Journal of Cardiology, verapamil has demonstrated a significant reduction in systolic and diastolic blood pressure levels compared to a placebo.
In terms of safety, Calan Sr is generally well-tolerated but may cause side effects such as dizziness, constipation, and fatigue in some individuals. It is essential to consult with a healthcare provider before starting Calan Sr to ensure its safety and effectiveness for your specific condition.
| Side Effect | Frequency |
|---|---|
| Dizziness | Common |
| Constipation | Common |
| Fatigue | Common |
It is important to note that while Calan Sr is effective in managing blood pressure and heart rhythm disorders, individual responses to the medication may vary. Therefore, regular monitoring by a healthcare professional is crucial to assess its efficacy and adjust the dosage if needed.
According to the American Heart Association, calcium channel blockers like Calan Sr are recommended as first-line treatments for hypertension in certain patient populations. These recommendations are based on comprehensive clinical trials and evidence-based guidelines that support the use of verapamil extended-release in the management of high blood pressure.
For more information on the effectiveness and safety of Calan Sr, you can refer to reputable sources such as the National Institutes of Health (NIH) or the American College of Cardiology (ACC) for up-to-date information and guidelines.
