Concor 10mg contains the active ingredient bisoprolol, a beta-blocker medication primarily used to manage high blood pressure (hypertension) and heart-related conditions such as angina (chest pain) and heart failure. Bisoprolol works by blocking the effects of adrenaline on the heart, which helps to reduce heart rate, lower blood pressure, and improve the heart's ability to pump blood efficiently. This medication is typically taken once daily, and the dosage may vary based on the specific condition being treated. Common side effects may include fatigue, dizziness, slow heart rate, or cold hands and feet.
