Eligibility Criteria

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Adult males who based on physician's recommedations will receive DINAPLEX®- Each hard capsule contains 0.5 mg dutasteride and 0.4 mg tamsulosin hydrochloride (equivalent to 0.367 mg tamsulosin) Tamsulosin hydrochloride Tamsulosin binds selectively and competitively to postsynaptic α1A adrenergic receptors and to a lesser extent to α1D adrenergic receptors. It relaxes the smooth muscles of the prostate and urethra. By relaxing the smooth muscle fibers of the bladder sphincter, it relieves obstructive effects and increases urine flow. It has little antihypertensive effect. Doutasteride Dutasteride lowers circulating dihydrotestosterone (DHT) levels by inhibiting the 5a-reductase isoenzymes type I and II, which are responsible for converting testosterone to DHT. The effect of dutasteride on DHT levels is dose-dependent and is observed within 1-2 weeks (85% and 90% reduction respectively).

You may qualify if:

  • Adult male patient with moderate to severe BPH symptoms receiving either monotherapy, dual medication as monoproducts or other stable combination and not responding adequately to treatment.
  • Adult male patient with BPH who has fully understood the study procedures and has signed a consent form after information.

You may not qualify if:

  • Patient who does not meet the criteria for taking the study drug (s), according to the Summary of Product Characteristics of each drug in the study.
