OBJECTIVES We evaluated the types of patient factors that influence the efficacy and safety of solifenacin add-on therapy to tamsulosin in men with overactive bladder (OAB) associated with benign prostatic hyperplasia (BPH). METHODS A total of 130 BPH patients with persistent OAB symptoms despite undergoing alpha1-adrenagic antagonist monotherapy were enrolled in this study. Their OAB symptom...

BACKGROUND Controversy remains on the superiority of combination therapy over monotherapy on ureteral stent-related symptoms (SRSs). We tend to explore if there is a necessity of combination therapy. METHODS One hundred cases of unilateral upper urinary tract calculi with stent insertion (pre and post flexible ureteroscopy) were randomized into 4 groups, given non-treatment, solifenacin, tams...

OBJECTIVES To develop a pharmacoeconomic study in order to know the average cost of BPH diagnosis and follow-up in Spain in the Urology Department setting from the perspective of the public health system, considering two frequently used drugs in the Spanish Healthcare environment, an alpha-blocker (tamsulosin) and the lipido-sterolic extract of Serenoa repens (Permixon). MATERIAL AND METHODS ...

OBJECTIVES To understand the mechanisms underlying ejaculation dysfunction caused by α1A-adrenocetor (AR) antagonists, the effects of α1A-AR antagonists on the contractile responses of the seminal vesicle were investigated. METHODS Isolated seminal vesicles from guinea pigs were cannulated and pressurized, and the changes in the intraluminal pressure were recorded. Periodic applications of el...

The efficacy of tamsulosin at the cost of a relatively benign side effect profile has been attributed to receptor selectivity directed at the alpha(1a) and alpha(1d) adrenergic receptor subtypes. The oral-controlled absorption system (OCAS((R))) represents a drug delivery refinement that incorporates a matrix of gel-forming and gel-enhancing agents to promote a constant drug release independent...

The study of distal ureter function was carried out on patients with stones in the upper urinary tract, who underwent ureteroscopy and lithotripsy procedures. The parameters of ureteral peristalsis such as peristalsis amplitude, peristalsis rate, ureteral wall tone, contractile wave duration, and its direction obtained by multichannel impedance ureterography were assessed and compared from two ...

Purpose. We evaluated the effectiveness and safety of tamsulosin, solifenacin, and combination of both in reducing double-J stent-related lower urinary symptoms. Materials and Methods. A total of 338 patients with double-J ureteral stenting were randomly divided, postoperatively, into 4 groups. In group I (n = 84), no treatment was given (control group), group II (n = 85) received tamsulosin 0....

In this study a sensitive, simple and accurate spectrophotometric method was suggested for determination of tamsulosin in bulk powder and pharmaceutical dosage form based on the formation of an ion-pair complex between the drug and bromocresol green in a buffer solution at pH 3.5. The formed yellow color complex was extracted with chloroform and measured at 415 nm. The optimum reaction conditio...

The present paper discusses the consequences of nocturia in patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) and summarises the available data on the impact of tamsulosin oral controlled absorption system (OCAS) on nocturia. The opinions of urologists on these data were assessed during a closed meeting in Marbella, Spain. Nocturia is the most both...

Objective: The present work was undertaken with the aim to develop and validate a rapid and consistent stability indicating RP-HPLC in which the peaks will be appear with short period of time as per ICH Guidelines. The proposed method was simple, fast, accurate and precise method for the Quantification of drug in the dosage form, bulk drug as well as for routine analysis in Quality control. Met...
