About Cazosin
What is Cazosin?
Cazosin is a medication containing Doxazosin 2 mg as its active ingredient. It belongs to the Alpha-1 adrenergic blocker class in the Quinazolines subgroup. This medication is registered in Thailand and manufactured by T.O. Pharma Co., Ltd.
Cazosin is used to treat two main conditions:
Hypertension (High Blood Pressure) — Can be used alone or combined with other antihypertensive medications
Benign Prostatic Hyperplasia (BPH) — Relieves symptoms such as difficulty urinating, incomplete bladder emptying, or straining to urinate
This is a controlled medication that must be used under the guidance of a doctor or pharmacist.
How Does Cazosin Work?
Cazosin acts as a Selective Alpha-1 Adrenergic Antagonist with the following mechanisms:
Lowering Blood Pressure
The drug blocks Alpha-1 receptors in arteries and veins, causing blood vessels to relax (vasodilation). This reduces peripheral vascular resistance, resulting in lower blood pressure.
Relieving BPH Symptoms
The medication relaxes smooth muscles in the bladder neck and prostate, allowing urine to flow more easily and reducing urinary obstruction symptoms.
Receptor Selectivity
Doxazosin has minimal effect on Alpha-2 receptors, resulting in fewer side effects related to the sympathetic nervous system compared to older medications.
Absorption and Elimination
The drug is rapidly absorbed, metabolized in the liver, and primarily excreted through feces. Its long-acting nature allows for once-daily dosing.
