Calcicard CR is a pharmaceutical medication primarily used in the management and treatment of various cardiovascular conditions. The "CR" in its name stands for "controlled release," indicating that the drug is formulated to release its active ingredient gradually over time, ensuring a more consistent therapeutic effect. Calcicard CR belongs to a class of drugs known as calcium channel blockers. These medications work by inhibiting the influx of calcium ions into cardiac and vascular smooth muscle cells, leading to relaxation of these muscles. This action effectively lowers blood pressure, reduces heart workload, and increases the supply of blood and oxygen to the heart. It is commonly prescribed for conditions such as hypertension (high blood pressure), angina pectoris (chest pain caused by reduced blood flow to the heart), and certain arrhythmias (irregular heartbeats). Patients are advised to follow their healthcare provider's instructions closely when taking Calcicard CR to ensure optimal outcomes and minimize potential side effects.
