Jalyn Elmes
Dutasteride/tamsulosin, sold under the brand name Jalyn among others, is a medication produced by GlaxoSmithKline for the treatment of adult male symptomatic benign prostatic hyperplasia (BPH). It is a combination of two previously existing medications: dutasteride, brand name Avodart, and tamsulosin, brand name Flomax. It contains 0.5 mg of dutasteride and 0.4 mg of tamsulosin, tamsulosin hydrochloride. Jalyn was the result of the Tamsulosin#Use in combination therapy, CombAT (Combination of Avodart and Tamsulosin) trial of 2008. It was approved by the U.S. Food and Drug Administration (FDA) on June 14, 2010. In June 2011, the FDA approved a label change to warn of "Increased Risk of High-grade Prostate Cancer" from Jalyn.

5α-Reductase Inhibitor
5α-Reductases, also known as 3-oxo-5α-steroid 4-dehydrogenases, are enzymes involved in steroid metabolism. They participate in three metabolic pathways: bile acid biosynthesis, androgen and estrogen metabolism. There are three isozymes of 5α-reductase encoded by the genes SRD5A1, SRD5A2, and SRD5A3. 5α-Reductases catalyze the following generalized chemical reaction: :a 3-oxo-5α-steroid + acceptor a 3-oxo-Δ4-steroid + reduced acceptor Where a 3-oxo-5α-steroid and acceptor are substrates, and a corresponding 3-oxo-Δ4-steroid and the reduced acceptor are products. An instance of this generalized reaction that 5α-reductase type 2 catalyzes is: :dihydrotestosterone + NADP+ \rightleftharpoons testosterone + NADPH + H+ where dihydrotestosterone is the 3-oxo-5α-steroid, NADP+ is the acceptor and testosterone is the 3-oxo-Δ4-steroid and NADPH the reduced acceptor. Production and activity The enzyme is produced in many tissues in both males and females, in the rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
