Why is this medication prescribed?

Cartia XT is a prescription medication primarily prescribed for the treatment of high blood pressure (hypertension) and to prevent certain types of chest pain (angina). It belongs to a class of drugs known as calcium channel blockers. Here’s some detailed information on its prescription and usage:

• Hypertension (High Blood Pressure): Cartia XT helps lower blood pressure by relaxing blood vessels, making it easier for the heart to pump blood.
• Angina: It can prevent angina (chest pain) caused by reduced blood flow to the heart muscles due to coronary artery disease.
