Tamsulosin hydrochloride capsule is a very effective drug for the treatment of prostate enlargement, which can relieve the symptoms of difficult urination relatively quickly. The main mechanism of action is to act on the smooth muscle of the bladder neck and prostate stroma, so that the tension of the smooth muscle weakens the main force of the urethra and improves the symptoms of difficulty in urination. Although these drugs work well, they also have side effects. For example, it can have a slight hypotensive effect and cause postural hypotension, so when taking the medication, it is usually taken at night before sleep to avoid symptoms such as falling or dizziness. Tamsulosin treatment for prostate enlargement is mostly combined with another drug, such as finasteride, and the two drugs together can have a more lasting effect.
