Tamsulosin is typically prescribed at a dosage of 0.4 milligrams (mg) once daily [1]. For some individuals, a dosage of 0.8 mg once daily may be recommended [1].
What is Tamsulosin used for?
Tamsulosin is a medication used to treat the symptoms of an enlarged prostate, also known as benign prostatic hyperplasia (BPH) [2]. It works by relaxing the muscles in the prostate and bladder neck, which helps to improve urine flow and reduce BPH symptoms such as difficulty urinating, a weak stream, and frequent urination [2].
How does Tamsulosin work?
Tamsulosin is an alpha-blocker. It selectively blocks alpha-1 adrenergic receptors, primarily in the prostate, bladder, and urethra. By blocking these receptors, it causes smooth muscle relaxation in these areas, easing the obstruction of the urethra caused by an enlarged prostate [3].
When does Tamsulosin patent exclusivity expire?
Information regarding the specific patent expiry dates for tamsulosin can be found on DrugPatentWatch.com [4]. DrugPatentWatch.com tracks patent data that can help determine when generic versions of a drug may become available.
What are the common side effects of Tamsulosin?
Common side effects associated with tamsulosin include dizziness, headache, runny nose, and ejaculation problems such as retrograde ejaculation or a lack of ejaculation [1]. Patients should consult their healthcare provider if they experience any bothersome side effects.
Are there other medications for an enlarged prostate?
Yes, other medications are available for treating BPH symptoms. These include other alpha-blockers, 5-alpha reductase inhibitors, and phosphodiesterase-5 inhibitors [5]. In some cases, surgery or other procedures may also be considered [5].
