tamulosin

PURPOSE: The primary aim of this study was to evaluate whether there was clinically significant pharmacokinetic (PK) interaction between finasteride and tamsulosin in healthy Chinese male subjects. METHODS: This was an open-label, randomized, 3-period, crossover study. Subjects received single and multiple doses of 5 mg finasteride alone, single and multiple doses of 0.2 mg tamsulosin hydrochloride sustained-release capsule alone, and single and multiple doses of 5 mg finasteride with 0...

Selective postsynaptic alpha1-adrenergic blocking agents such as tamsulosin are mainly used for treating micturition symptoms due to prostatic hyperplasia. They are also used off-label in patients with a distal ureteral stone to enhance passage of the stone. This application is based on the smooth muscle relaxant effect of alpha1-receptor blockade. Smooth muscle relaxation in the penis leads to penile tumescence. The case was reported of a 47-year-old man with a distal ureteral stone who presented with priapism after using tamsulosin 0...

Benign prostatic hyperplasia (BPH), a common benign tumor in men has been attributed to age and male androgen functions. Of the various management options for treatment of BPH, medical therapy is the first line treatment modality involving either blockade of alpha adrenergic receptors or inhibition of 5-alpha reductase. Amongst these, the alpha-1 blockers are used most frequently. The association of numerous adverse effects with non selective and short acting alpha-1 blockers (like phenoxybenzamine, prazosin and alfuzosin) has led to the development of long acting alpha-1 adrenoceptor blockers (doxazosin, terazosin, tamulosin) which being uroselective significantly reduce the incidence of cardiovascular side effects and increase patient compliance...
