Benign prostate hyperplasia (BPH) is a common urinary disease with pathological feature of non-malignant hyperplasia in prostatic tissue. 2007;29(1):1725. Meta-analysis of Qmax changes of tadalafil vs. tamsulosin. Myalgia, headache, backpain, nasopharyngitis, and dizziness were the most common TEAEs reported. published the results of the first randomized clinical trial (RCT) on the use of tadalafil to treat LUTS due to BPH [14]. The clinical improvement in IPSS-total score with tadalafil and tamsulosin was seen in approximately 70% of the patients in our study. Egerdie RB, Auerbach S, Roehrborn CG, Costa P, Garza MS, Esler AL, et al. In fact, the first clinical study evaluating whether tadalafil can improve LUTS due to BPH was conducted in 2006 [21], and since then numerous other RCTs were performed to explore the differences between tadalafil and tamsulosin [22]. Kaminetsky J. Comorbid LUTS and erectile dysfunction: Optimizing their management. Adverse events with tadalafil and tamsulosin, Clinical response with Tadalafil and Tamsulosin (A1, B1, B2, A2). Total IPSS decrease was 5.00.4 in the tadalafil 2.5mg group, 5.10.4 in tadalafil 5mg, 5.60.4 in tamsulosin 0.2mg, and 3.00.4 in the placebo group. Flomax and Cialis belong to different drug classes. Sairam K, Kulinskaya E, McNicholas TA, Boustead GB, Hanbury DC. Gacci, Mauro, Giovanni Corona, Matteo Salvi, Linda Vignozzi, Kevin T. McVary, Steven A. Kaplan, Claus G. Roehrborn et al. Search terms were tadalafil, tamsulosin, lower urinary tract symptoms, and controlled. 1 (2019): 44. Interestingly, several recent studies have found that tadalafil can relieve both storage and voiding symptoms [11,12], and an increasing number of studies have focused on comparing the efficacy of tadalafil versus tamsulosin in the treatment of LUTS. Line diagram showing change in various assessment parameters in tadalafil and tamsulosin during the study. Ultimately, the basic characteristics and results of the selected studies were extracted and recorded in the data extraction tables. Effects of tadalafil on lower urinary tract symptoms secondary to benign prostatic hyperplasia in men with or without erectile dysfunction. published the results of their 12-week RCT evaluating 151 Asian men complaining LUTS treated with tadalafil 2.5mg, 155 with tadalafil 5mg, 152 with tamsulosin 0.2mg as active control, and 154 with placebo. The meta-analysis results showed there was no statistical difference between tadalafil and tamsulosin in improving voiding subscores (SMD: 0.19, 95% CI: 1.78 to 1.41, P=0.82, Figure 3). This is the clinical response criteria as per the AUA guidelines which suggests a >3 point decrease in total IPSS score from the baseline is indicative of a clinically meaningful improvement and this change is also consistent with that observed in other published tamsulosin and tadalafil studies.[9,10,12,13,14,15,17,18]. Twenty patients were allocated to each of the two treatment groups in a randomized double blind manner. There are few reports in the literature showing that PDE 5 inhibitors (e.g., tadalafil) induce relaxation of smooth-muscle cells in the urethra, prostate, and bladder neck [20]. Oelke M, Giuliano F, Baygani SK, Melby T, Sontag A. Donatucci CF, Brock GB, Goldfischer ER, et al. Metabolic Syndrome (MetS) is a complex epidemic disorder with an impact on both lower urinary tract symptoms (LUTS) and erectile dysfunction (ED).

Next, the same 2 authors each read the full texts of the screened articles to confirm whether they met the inclusion criteria. Despite the interesting results, the authors stated that the study was not powered for a direct comparison of tadalafil and tamsulosin [26]. Kumar R, Nehra A, Jacobson DJ, McGree ME, Gades NM, Lieber MM, et al. Blocking specific receptors (e.g., alpha receptor, phosphodiesterase type-5) can relax smooth muscle in the prostate and bladder neck, which results in improved urinary flow and amelioration of LUTS [9,10]. Third, as the LUTS parameters did not return to baseline during the 4 week placebo wash out period, the treatment effect in period 2 (12 weeks to 18 weeks) could not be specifically evaluated. No potential conflicts of interest from any authors. Only tadalafil showed a significant improvement of ED [29]. Urios A, Ordoo F, Garca-Garca R, et al. They were advised to preserve the emptied blister packs of the drugs and mark in the compliance assessment sheet for the days on which they had taken the drug. Triumph Pan European Expert Panel. J Urol. IIEF-EF domain scores improved in both the tadalafil 2.5mg group (n=198) and the tadalafil 5mg group (n=208), compared with placebo (n=200).

At the end of the trial, total, voiding, and storage IPSS were significantly better in the combination arm compared with tamsulosin (9.75 vs 6, p=0.01; 6.3 vs 4.5, p=0.01; 3.9 vs 1.5, p=0.05) [32]. Whether they are safe and effective when combined is still under investigation. The mean difference in IPSS-total score, IPSS-voiding score, IPSS-storage score, IPSS-QOL score, PVR, cQmax and IIEF score between Tadalafil and Tamsulosin was 0.03, 0.19, 0.15, 0.26, 21.22, 0.04 and 1.55 respectively. Verhamme KMC, Dieleman JP, Bleumink GS, et al. 2008;5(9):21708. Choi WS, Heo NJ, Lee YJ, et al. Efficacy of continuous dosing of tadalafil once daily. Preclinical evidence demonstrated that penile tissue, along with bladder and prostate, is enriched of PDE5, thus rendering these tissues the preferential targets of PDE5 inhibitors and susceptible to their beneficial effects. Kim JH, Baek MJ, Sun HY, Lee B, Li S, Khandwala Y, et al. The prevalence of lower urinary tract symptoms in men and women in four centres. Likewise, IIEF-EF improved vs placebo with tadalafil (+4.0; p<0.001) but not with tamsulosin (0.4; p=0.699). Journal of clinical medicine8, no. In the group BA, the mean change during 28 weeks in IPSS-total score was -6.29, IPSS-voiding score was -4.58, IPSS-storage score was -1.70, IPSS-QOL score was -1.52, PVR was -41.23, cQmax was + 0.07 and IIEF score was +2.20. 1Department of Urology, Beijing Hospital, National Center of Gerontology; Institute of Geriatric Medicine, Chinese Academy of Medical Sciences/Graduate School of Peking Union Medical College, Beijing, P.R. Six studies [1419] described the number of and reasons for subject withdrawals prior to completion of treatment. Broderick GA, Brock GB, Roehrborn CG, Watts SD, Elion-Mboussa A, Viktrup L, et al. Total, storage, and voiding IPSS were significantly improved compared to baseline in all the 3 arms, being significantly better in the combination group (all p<0.05). Factors that influence lower urinary tract symptom (LUTS)-related quality of life (QoL) in a healthy population. Although both the classes of drugs have been shown to significantly improve LUTS when used as monotherapy and an additive effect has also been reported in a few studies,[7,9,11,12] there are many clinical questions which remain undefined.

Curr Urol Rep 21, 56 (2020). Three studies [13,15,17] used a stochastic approach (random sequence). Only tadalafil 5mg showed a significant least squares (LS) mean difference in total IPSS compared with placebo (=1.2; p=0.035). They were packed in blister packs in a GMP (good manufacturing practices) certified facility. Effect of the Treatment with respect to baseline in each of the treatment groups. Meta-analysis of the voiding subscores change using tadalafil vs. tamsulosin. Sebastianelli, A., Spatafora, P., Morselli, S. et al. Eur Urol. Therefore, the use of daily tadalafil 5mg in monotherapy for the treatment of patients complaining both LUTS and ED appears more and more persuasive, thanks also to the good safety and tolerability profile, as shown in our systematic review. Three of these were found to be on Tamsulosin treatment, revealed at the end of the study period. The observation that when tadalafil was crossed over to tamsulosin, there was a significant improvement in IPSS voiding, while when tamsulosin was changed over to tadalafil there was a significant improvement in IIEF score over the, hints about predominant effect of these two classes of drugs. ", Porst, Hartmut, Kevin T. McVary, Francesco Montorsi, Peter Sutherland, Albert Elion-Mboussa, Anne M. Wolka, and Lars Viktrup. enrolled 151 Korean men, randomly assigned to receive once daily tadalafil 5mg, tamsulosin 0.2mg, or placebo for 12weeks. Tadalafil treatment improves inflammation, cognitive function, and mismatch negativity of patients with low urinary tract symptoms and erectile dysfunction. 2013;10(3):85765. In the placebo group, 19.5% of men experienced 1 TEAE, compared with 29.8% in tadalafil 2.5mg, 30.3% in tadalafil 5.0mg, and 24.3% the in tamsulosin group. The combination of daily tadalafil 5mg and tamsulosin 0.4mg allows a better improvement of LUTS compared with both the monotherapies, even if with an increased, but acceptable and tolerated, adverse events rate. Int Urol Nephrol. Of the 4 retrieved trials, two evaluated daily tadalafil 5mg (one not in English language), one tadalafil 10mg, and one tadalafil 20mg. https://doi.org/10.1016/j.eururo.2012.02.033. How it works Upsides Downsides Bottom Line Tips Response/effectiveness Interactions 1. Available from:. Nevertheless, tadalafil, but not tamsulosin, was able to significantly improve IPSS QoL Index and Treatment Satisfaction ScaleBPH compared with placebo (both p<0.05 vs both p>0.1). All men reported urinary symptoms as well as erectile dysfunction. On one hand, these medicines provide multiple treatment options . BPH can cause uncomfortable. We did not perform a pharmacokinetic assessment of active drug which could have differentiated between the two. World J Urol. Symptoms of ED include. confirmed in 2010 the significant effect of tadalafil 20mg on IPSS, compared with placebo (mean difference between treatments: 4.2, p<0.001), but they failed to prove a significant impact of tadalafil on urodynamic parameters. ". Google Scholar. Drug and food interactions Moderate tamsulosin food Applies to: tamsulosin Food may affect the intestinal absorption of tamsulosin. As a first-line treatment for ED, tadalafil has been recently gaining popularity for managing LUTS secondary to BPH. Patients were provided with 2 weeks of therapy along with compliance assessment sheet and were required to report at each follow-up visit. Second, positive effects with tadalafil on voiding and storage scores were also confirmed by our analysis, as were the improvements in postvoid residual urine (WMD: 4.24, 95% CI: 1.74 to 10.22) and maximum flow rate (SMD: 0.59, 95% CI: 1.73 to 0.54). (Viagra), tadalafil (Cialis), and vardenafil (Levitra). Total (1.50.5 (2.4 to 0.6); p<0.001), storage (0.60.2 (0.9 to 0.2); p=0.002), voiding (0.90.3 (1.5 to 0.3); p=0.002), and QoL IPSS (0.20.1 (0.4 to 0.0); p=0.038) were all significantly improved compared with placebo. Dunn CJ, Matheson A, Faulds DM. compared, in a 12-week RCT, 171 men in the tadalafil 5mg group, 168 in the tamsulosin 0.4mg group, and 172 in the placebo group, after 4weeks of placebo run-in. Aim of our systematic review is to evaluate and summarize the efficacy and safety of tadalafil alone or in combination with tamsulosin for the management of LUTS/BPH and ED. Giuliano F, ckert S, Maggi M, et al. After all, if ED and LUTS-BPH can be alleviated with monotherapy, the role of combination therapy seems to be unnecessary, since a kill two birds with one stone strategy would be advisable. National Library of Medicine In conclusion, daily tadalafil, in particular at dosage of 5mg, is effective for the treatments of LUTS/BPH and ED. The process was accomplished independently by the first 2 authors. Low Urin Tract Symptoms. Moreover, tadalafil 5mg (1.7, p=0.021), but not tadalafil 2.5mg (1.5; p=0.072), significantly improved IPSS storage subscore compared with placebo, and a similar reduction was observed with tamsulosin 0.2mg (1.70.2) [25]. Out of these 10 articles, 7 randomized controlled trials (RCTs) [1319] with 1601 subjects met all of the inclusion criteria. Pogula VR, Kadiyala LS, Gouru VR, et al. There was significant change in IPSS-total score (P = 0.00), IPSS-voiding score (P = 0.00), IPSS-storage score (P = 0.00), IPSS QOL score (P = 0.00) and IIEF scores (P = 0.02) with Tadalafil. Our meta-analysis showed that tadalafil has a comparable effect as tamsulosin in managing LUTS. Discontinuation of tamsulosin or tadalafil, after combination therapy, seems to allow a preservation of the results obtained for LUTS relief. Tadalafil, as a long-acting PDE-5 inhibitor, is believed to increase activity of the NO/cGMP pathway and subsequently exert a positive effect on lower urinary tract function [2628], but existing studies comparing tadalafil and tamsulosin were all RCTs with short treatment duration (the duration of each study in this meta-analysis was 12 weeks). No significant placebo effects were observed. 2009;6(6):1594608. Out of the 40 patients, 36 completed the study. There was no significant change in PVR (P = 1.00) and cQmax (P = 1.00). Two patients had myalgia's, one had calf pain, one complained of decreased seminal volume and one patient developed herpes zoster during the study while on tadalafil. From 335 screened articles, 7 studies (totalling 1601 patients) were finally included in our analysis. Demographic and baseline characteristics were comparable between the two groups (AB and BA). LUTS and male sexual dysfunction: the multi-national survey of the aging male (MSAM-7). A comparative randomized prospective study to evaluate efficacy and safety of combination of tamsulosin and tadalafil vs. tamsulosin or tadalafil alone in patients with lower urinary tract symptoms due to benign prostatic hyperplasia. Erectile dysfunction and lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH) combined responders to tadalafil after 12 weeks of treatment. Before Data was expressed as mean + SD, scores (median and inter quartile range) or proportions as appropriate. Moreover, tadalafil 5mg significantly improved Sexual Encounter Profile Question 3 (SEP Q3) and BPH Impact Index (BII) (p<0.001) [18]. Thus, if the duration of trial is long, subjective scores depict higher response rates as shown in the alfuzosin and tamsulosin cross-over trial by Karada et al. Kim SC, Park JK, Kim SW, Lee SW, Ahn TY, Kim JJ, et al. Pilot study. "Monotherapy with tadalafil or tamsulosin similarly improved lower urinary tract symptoms suggestive of benign prostatic hyperplasia in an international, randomised, parallel, placebo-controlled clinical trial." A pilot crossover RCT aimed to assess the efficacy of tamsulosin plus tadalafil vs tamsulosin in the treatment of men with LUTS/BPH was published by Bechara et al. Tadalafil once daily for lower urinary tract symptoms suggestive of benign prostatic hyperplasia: a randomized placebo- and tamsulosin-controlled 12-week study in Asian men. Treatment effect of Tadalafil and Tamsulosin considering both the periods. An IIEF score 26 was reported by 46.7% in the combination group with tamsulosin 0.4mg, 50.68% in combination with tamsulosin 0.2mg, and 46.71% in tadalafil monotherapy. The allocation was concealed from the investigator who recruited the patients and assessed the outcomes. Only 2 studies [15,16] provided valid data on International Index of Erectile Function scores (IIEF scores). A comparative randomized prospective study to evaluate efficacy and safety of combination of tamsulosin and tadalafil vs. tamsulosin or tadalafil alone in patients with lower urinary tract symptoms due to benign prostatic hyperplasia. Write a review. Indeed, no statistically or clinically significant differences were observed between tadalafil and placebo groups in maximum urinary flow rate (Qmax), detrusor pressure at Qmax (PdetQmax), or bladder capacity [23]. PLoS One. Correspondence to Qmax and PVR significantly changed from baseline, without any statistically significant difference in the 2 groups (combination vs tamsulosin: +3 vs +2.1; p>0.05; and 38.7 vs 35.2; p>0.05). Discrepancies between the 2 authors were arbitrated by the senior author. Elderly men are more likely to experience LUTS [2], and the prevalence ranges from 10.3% to 25.1% [35]. Also, PGI-I and CGI-I were significantly better in the tadalafil group. The site is secure. being able to get an erection sometimes, but not every time you want to have sex.
