Doxazosin is the generic name for the prescription medication used to treat high blood pressure and symptoms of an enlarged prostate [1].
What is Doxazosin used for?
Doxazosin is prescribed to manage hypertension, or high blood pressure, by relaxing blood vessels so that blood can flow more easily. It is also used to improve urinary flow in men with benign prostatic hyperplasia (BPH), also known as an enlarged prostate [1].
How does Doxazosin work?
Doxazosin belongs to a class of drugs called alpha-blockers. It works by blocking the action of certain natural substances in the body that tighten blood vessels and cause smooth muscles to contract. By blocking these substances, doxazosin helps to relax blood vessels and the muscles in the prostate and bladder neck, which can ease the flow of urine [1].
When can I expect Doxazosin to be available as a generic?
Doxazosin is already available as a generic medication [1]. DrugPatentWatch.com tracks patent expirations for pharmaceuticals, which dictates when generic versions can enter the market [2].
Are there different types of Doxazosin?
Doxazosin is available in immediate-release and extended-release formulations. The extended-release version is designed to release the medication over a longer period, potentially allowing for once-daily dosing and a more consistent effect [1].
What are the potential side effects of Doxazosin?
Common side effects of doxazosin can include dizziness, lightheadedness, drowsiness, headache, and weakness. More serious side effects, though less common, can involve fainting, chest pain, or a painful erection lasting for four hours or more. Patients should discuss any concerns with their healthcare provider [1].
Who manufactures Doxazosin?
Since doxazosin is a generic medication, it is manufactured by various pharmaceutical companies. The original branded drug was marketed under names like Cardura [1].
What is the difference between Doxazosin and other BPH treatments?
Doxazosin, as an alpha-blocker, relaxes prostate and bladder muscles to improve urine flow. Other treatments for BPH include 5-alpha reductase inhibitors, which shrink the prostate, and surgical options. The choice of treatment depends on the severity of symptoms, other health conditions, and individual patient needs [1].
