Introduction About CILACAR 20MG TABLET
CILACAR 20 TABLET contains cilnidipine, which belongs to the group of medicines called calcium channel blockers. It is used to manage high blood pressure (hypertension). It also helps to lowering the risk of heart attack and stroke.
Cilacar 20 Tablet may be used alone or with other medicines, depending on your condition. Your doctor will decide the right dose for you. You can take it any time of day, with or without food, but try to take it at the same time daily. Continue taking it as long as your doctor recommends. Do not stop this medicine on your own, even if you feel well, because high blood pressure may not show symptoms and stopping suddenly could worsen your condition.
Staying physically active, maintaining a healthy weight, and eating a nutritious diet can all help manage your blood pressure. Always follow your doctor’s instructions when taking this medication.
The most common side effects include swelling in ankles, feet and other body parts, headache, dizziness, fatigue, sleepiness and tiredness, flushing, skin reactions, low blood pressure, palpitations, gingival hyperplasia, other mouth related effects, abdominal and muscle pain. If you experience any side effects that bother you or do not go away, consult your doctor. Research indicates that this medication may also help protect the kidneys.
Before taking this medication, inform your doctor about any existing liver, kidney, or heart conditions. If you are pregnant or breastfeeding, consult your doctor before taking this medicine. Make sure to mention any other medications you are currently using, particularly those for high blood pressure or heart problems. Regular blood pressure checks are recommended to monitor how well the management is working.
Uses Of CILACAR 20MG TABLET
- High blood pressure (hypertension)
- Lowering the risk of heart attack and stroke
Benefits of CILACAR 20MG TABLET
1) Blood Pressure Management
One of the primary benefits of CILACAR 20 is its ability to effectively manage high blood pressure. By relaxing the blood vessels, the medication allows blood to flow more easily, reducing the pressure that the heart needs to exert to pump blood. It is suitable for patients with mild to moderate hypertension and is often used in combination with other antihypertensive drugs if blood pressure is not adequately controlled by a single medication.
2) Cardiovascular Support and Heart Function
CILACAR 20 supports overall cardiovascular health by reducing the workload on the heart. Lowering the resistance in the blood vessels helps the heart pump more efficiently, which can be particularly beneficial for patients at risk of developing heart failure. In the long term, this reduces the chances of cardiac complications such as heart attacks, strokes, and heart muscle thickening (left ventricular hypertrophy), which are common in people with uncontrolled hypertension.
3) Kidney Protection in Diabetic Patients
Cilnidipine also offers kidney-protective effects, especially in patients with diabetes and hypertension, a group at high risk of developing kidney disease. Studies have shown that cilnidipine can reduce proteinuria (excess protein in urine), an early sign of kidney damage. By managing blood pressure and reducing stress on the kidneys, CILACAR 20 helps preserve kidney function over time, making it a valuable choice in diabetic hypertensive patients.
4) Improved Tolerability and Fewer Side Effects
Compared to other calcium channel blockers such as amlodipine, cilnidipine is associated with fewer side effects, particularly pedal edema (swelling of the feet and ankles), which is a common complaint with other medications in this class. This improved tolerability can help patients adhere to their management plan more consistently, which is crucial for long-term blood pressure control.
5) Enhanced Quality of Life and Exercise Tolerance
By reducing blood pressure and improving blood circulation, CILACAR 20 can help patients experience better physical endurance and reduced fatigue. This may support greater engagement in daily activities and exercise, contributing to a better quality of life and helping to manage other conditions like obesity, diabetes, or heart disease.
How CILACAR 20MG TABLET Works
CILACAR 20 Tablet contains cilnidipine, a calcium channel blocker that acts by relaxing the smooth muscle in the walls of blood vessels. This relaxation widens (dilates) the blood vessels, allowing blood to flow more easily and reducing the pressure exerted on the vessel walls. As a result, the heart does not have to work as hard to pump blood, which helps maintain healthy blood pressure and supports overall cardiovascular function.
Blocks Calcium Channels for Vascular Relaxation
By blocking calcium channels, CILACAR 20 Tablet reduces calcium ion influx into vascular smooth muscle cells. This prevents the muscles from contracting tightly, leading to relaxation and dilation of blood vessels.
Supports Blood Vessel Relaxation and Improved Blood Flow
The relaxation of blood vessels improves blood flow throughout the body. Enhanced blood flow ensures that organs and tissues receive adequate oxygen and nutrients, which is essential for maintaining healthy cardiovascular function.
Reduces Strain on the Heart and Supports Cardiovascular Health
With blood vessels relaxed, the heart does not have to pump as hard to circulate blood. This reduces the workload on the heart, lowers the risk of heart-related complications, and supports overall heart health.
Inhibits Calcium Ion Influx to Lower Blood Pressure
The inhibition of calcium ion influx into vascular smooth muscle cells is central to the blood pressure-lowering effect of CILACAR 20 Tablet. By preventing calcium-mediated contraction, the drug maintains lower blood pressure.
Suppresses Norepinephrine Release for Stress Blood Pressure Control
Cilnidipine’s action on N-type calcium channels at sympathetic nerve endings reduces the release of norepinephrine. This suppresses the body’s stress response that would otherwise increase blood pressure, providing additional control over blood pressure spikes during stressful situations.
