Overview
Cardura 2mg Tablet contains doxazosin 2mg, an alpha-1 adrenergic blocker used to treat high blood pressure (hypertension) and the urinary symptoms of benign prostatic hyperplasia (BPH), a non-cancerous enlargement of the prostate gland in men.
Doxazosin works by blocking alpha-1 receptors in the smooth muscle of blood vessels, causing them to relax and widen, which lowers blood pressure. It also relaxes smooth muscle in the prostate and bladder neck, which eases the flow of urine in men with an enlarged prostate.
How it Works
Doxazosin selectively blocks postsynaptic alpha-1 adrenergic receptors, reducing the constricting effect of noradrenaline on vascular smooth muscle and lowering peripheral vascular resistance. In the prostate and bladder neck, the same alpha-1 blockade relaxes smooth muscle tone, reducing resistance to urine flow and easing BPH symptoms.
Directions for Use
Take Cardura 2mg Tablet at about the same time each day, with or without food. Swallow the tablet whole with a glass of water. Take special care with your first dose and after any dose increase, as a sudden drop in blood pressure on standing is most likely at these times – it is often advised to take the first dose before bed.
Dosage
The usual starting dose of Cardura 2mg Tablet is 1mg once daily, which your doctor may gradually increase depending on your blood pressure or urinary symptom response, up to a maximum typically around 8mg daily. The first dose is usually taken at bedtime to reduce the risk of dizziness.
