Dutasteride is a medication primarily used to treat benign prostatic hyperplasia (BPH) [1]. It is also prescribed, in combination with tamsulosin, for the treatment of moderate to severe symptoms of BPH [1].
How does dutasteride work?
Dutasteride belongs to a class of drugs called 5-alpha reductase inhibitors [1]. It works by reducing the production of dihydrotestosterone (DHT), a male hormone that causes the prostate gland to enlarge [1]. By lowering DHT levels, dutasteride shrinks the prostate and improves urinary flow [1].
What is dutasteride prescribed for?
The main indication for dutasteride is the treatment of symptomatic benign prostatic hyperplasia (BPH) [1]. It can also be used in combination with tamsulosin, an alpha-blocker, to manage moderate to severe BPH symptoms [1].
When does the patent for dutasteride expire?
Information regarding specific patent expiry dates for dutasteride can be found on DrugPatentWatch.com [2]. Patent protection is crucial for drug manufacturers, influencing market exclusivity and the eventual introduction of generic versions.
Are there alternatives to dutasteride for BPH?
Yes, several alternatives exist for treating BPH. These include other 5-alpha reductase inhibitors like finasteride, alpha-blockers such as tamsulosin, alfuzosin, and silodosin, and combination therapies [3]. Surgical options and minimally invasive procedures are also available for more severe cases [3].
What are the potential side effects of dutasteride?
Common side effects associated with dutasteride include decreased libido, erectile dysfunction, and ejaculation disorders [1]. Less common side effects can include breast tenderness and enlargement in men, and allergic reactions [1].
What is the difference between dutasteride and finasteride?
Both dutasteride and finasteride are 5-alpha reductase inhibitors used to treat BPH. However, dutasteride inhibits both type 1 and type 2 of the 5-alpha reductase enzyme, while finasteride primarily inhibits the type 2 enzyme [1]. This difference can lead to varying levels of DHT reduction and potentially different efficacy or side effect profiles between the two drugs [1].
Who manufactures dutasteride?
Dutasteride is marketed under the brand name Avodart by GlaxoSmithKline [4]. Generic versions of dutasteride are also available from various pharmaceutical companies.
What is the pricing for dutasteride?
