What is Stamlo 5?
Stamlo 5 is a brand name for a medication whose active ingredient is amlodipine. It belongs to a class of drugs known as calcium channel blockers (CCBs). These medications work by blocking the entry of calcium ions into the cells of the heart and blood vessel walls, which causes the blood vessels to relax and widen. This relaxation has a two-fold benefit for cardiovascular health, as it both lowers blood pressure and increases the supply of blood and oxygen to the heart. Stamlo 5 is manufactured by Dr. Reddy's Laboratories.
Primary Medical Uses of Stamlo 5
Stamlo 5 is prescribed for several key cardiovascular conditions. These include:
Treatment of Hypertension
One of the main uses of Stamlo 5 is the management of hypertension, or high blood pressure. By relaxing and widening blood vessels, it reduces the pressure on the arteries, which allows blood to flow more easily. This sustained reduction in blood pressure over time helps to significantly lower the risk of serious health complications, such as stroke, heart attack, and kidney problems.
Management of Angina
Stamlo 5 is also used for the symptomatic treatment of certain types of angina, which is chest pain caused by reduced blood flow to the heart muscle. It is effective for treating both chronic stable angina and vasospastic angina (Prinzmetal's or variant angina). By increasing the supply of blood and oxygen to the heart, it can help reduce the frequency and severity of angina attacks.
Other Cardiovascular Conditions
In patients with recently documented coronary artery disease (CAD), Stamlo 5 may be used to help reduce the risk of hospitalization for angina and the need for coronary revascularization procedures. It is a long-term treatment that can be used alone or in combination with other heart medications to protect overall heart health.
How Stamlo 5 Works: The Pharmacological Mechanism
The active ingredient, amlodipine, works by selectively inhibiting the flow of calcium ions into vascular smooth muscle cells and cardiac muscle cells. Amlodipine primarily affects the vascular smooth muscle, causing vasodilation. This effect reduces peripheral vascular resistance, the resistance to blood flow in the arteries. By decreasing this resistance, the heart does not need to pump as hard, thereby reducing blood pressure. For angina, the mechanism involves both the reduction of the heart's workload and the dilation of the coronary arteries, which increases oxygen delivery to the heart muscle.
Administration
The administration of Stamlo 5 (amlodipine) is determined by a physician based on the patient's condition and response to treatment. It is typically taken orally once a day, with or without food, at the same time each day for optimal results. Regular administration helps maintain consistent blood levels of the medication. It is crucial not to stop taking the medication abruptly, as this can cause a rapid increase in blood pressure or worsen angina symptoms.
Potential Side Effects and Precautions
Like all medications, Stamlo 5 can cause side effects. Many are mild and resolve as the body adjusts to the medicine.
Common side effects include:
- Swelling of the hands, feet, or ankles (edema)
- Headache
- Dizziness or lightheadedness
- Flushing (a feeling of warmth or redness)
- Fatigue or drowsiness
- Nausea or stomach pain
Serious but less common side effects can include:
- Chest pain that is more frequent or severe
- Rapid or irregular heartbeat
- Fainting
- Gum tenderness or bleeding
Precautions:
- Drug Interactions: Stamlo 5 can interact with other medications, such as certain antibiotics, antifungals, immunosuppressants (like cyclosporine or tacrolimus), and other blood pressure medicines. Patients should inform their doctor about all other drugs, including over-the-counter medications, herbal products, and supplements. Grapefruit juice should be avoided as it can affect drug levels.
- Medical Conditions: Individuals with liver problems, congestive heart failure, or severe aortic stenosis should use this medication with caution and under strict medical supervision.
Comparison: Stamlo 5 (Amlodipine) vs. Metoprolol
While both Stamlo 5 and Metoprolol are used to treat hypertension and other heart conditions, they belong to different classes of medication (calcium channel blocker vs. beta-blocker) and have distinct mechanisms and side effect profiles. Some combination products like Met Stamlo Active exist.
| Feature | Stamlo 5 (Amlodipine) | Metoprolol (Beta-Blocker) |
|---|---|---|
| Drug Class | Calcium Channel Blocker (Dihydropyridine) | Beta-Blocker (Cardio-selective) |
| Mechanism of Action | Relaxes and widens blood vessels by blocking calcium channels. | Blocks beta-receptors, primarily affecting the heart by slowing heart rate and reducing workload. |
| Effect on Blood Vessels | Direct vasodilation, most effective on arteries. | Decreases blood pressure through several mechanisms, but less direct vasodilation. |
| Effect on Heart Rate | Minimal effect on heart rate; can sometimes cause reflex tachycardia, but long-term use is associated with improved sympathetic activity control. | Directly slows heart rate. |
| Primary Use Cases | Hypertension, chronic stable angina, vasospastic angina. | Hypertension, angina, arrhythmia, post-heart attack management. |
| Common Side Effects | Ankle swelling, headache, dizziness, flushing. | Slow heart rate, fatigue, dizziness, depression. |
| Contraindications | Severe hypotension, cardiogenic shock, aortic stenosis. | Sinus bradycardia, heart block (2nd/3rd degree), overt cardiac failure. |
Lifestyle Changes and Long-Term Management
Effective management of high blood pressure and angina with Stamlo 5 often requires complementary lifestyle changes. A low-sodium diet, regular physical activity, maintaining a healthy weight, and limiting alcohol and smoking are all integral to achieving and maintaining optimal cardiovascular health. Your doctor will also recommend regular blood pressure monitoring to ensure the medication is working effectively.

Conclusion
Stamlo 5, containing the active ingredient amlodipine, is an effective and widely used calcium channel blocker for the treatment of high blood pressure and angina. By relaxing blood vessels and improving blood flow, it significantly reduces the risk of future cardiovascular events such as heart attacks and strokes. While generally well-tolerated, it is essential to be aware of its potential side effects and to inform your healthcare provider of any other medications or conditions you may have. Adherence to the prescribed administration and a healthy lifestyle are crucial for maximizing the benefits of Stamlo 5 and protecting your long-term heart health.
