Contents of the pack
Dutasteride/Tamsulosin Krka is used in men to treat an enlarged prostate (benign prostatic hyperplasia) - a non-cancerous growth of the prostate caused by overproduction of a hormone called dihydrotestosterone.
Dutasteride/Tamsulosin Krka is a combination of two different medicines called dutasteride and tamsulosin. Dutasteride belongs to a group of medicines called 5-alpha reductase inhibitors and tamsulosin belongs to a group of medicines called alpha blockers.
As the prostate grows, it can cause urinary problems such as difficulty in the flow of urine and a need to urinate more frequently. It can also cause the stream of urine to be weaker and less forceful. If left untreated, there is a risk that the flow of urine will be completely blocked (acute urinary retention). This requires immediate medical treatment. In some cases, surgery may be necessary to reduce the size of the prostate or to remove it.
Dutasteride reduces the production of the hormone called dihydrotestosterone, which helps to reduce the size of the prostate and relieve symptoms. This reduces the risk of acute urinary retention and the need for surgery. Tamsulosin works by relaxing the muscles in the prostate, making it easier to urinate and quickly improving symptoms.
