Calan 40mg tablets contain the active ingredient verapamil hydrochloride, which is a calcium channel blocker medication used to treat high blood pressure (hypertension), angina (chest pain), and certain types of irregular heartbeats (arrhythmias).
Verapamil works by relaxing and widening the blood vessels, which helps to reduce blood pressure and increase blood flow to the heart. It also helps to reduce the heart's workload and oxygen demand, which can relieve chest pain and prevent irregular heartbeats.
Calan 40mg tablets are typically taken orally, with or without food, as directed by a healthcare provider. The recommended dosage and duration of treatment may vary depending on the patient's age, weight, and medical condition.
It is important to note that Calan may have side effects, including dizziness, headache, and constipation. Patients taking this medication should inform their healthcare provider if they experience any adverse reactions or have concerns about their treatment.
Additionally, patients taking Calan should inform their healthcare provider of any other medications they are taking, as it can interact with other drugs. Calan may also not be suitable for patients with certain medical conditions, such as severe heart failure or low blood pressure. It is important to consult with a healthcare provider before taking this medication, especially if you have any underlying medical conditions or are taking other medications.
