Medications for prostate enlargement include alpha 1 receptor blockers, 5 alpha reductase inhibitors and M receptor antagonists. It is recommended to use medication under the guidance of a doctor, and the specific medication program is different for different situations. 1. α1 receptor blocker: α1 receptor is mainly distributed in the prostate stromal smooth muscle, which has a greater impact on urination. Blocking α1 receptor can effectively reduce the smooth muscle tension of the bladder neck and prostate, reduce urethral resistance, and improve urination function. One of the commonly used drugs includes tamsulosin, etc., which has better efficacy and milder side effects for prostate enlargement patients with milder symptoms. 2. 5α reductase inhibitors: 5α reductase inhibitors prevent the conversion of testosterone to active dihydrotestosterone in the prostate, which in turn partially reduces the size of the prostate and improves urinary symptoms. This medication is more effective for larger prostates and needs to be taken for a longer period of time, and is more effective in combination with alpha blockers. Commonly used drugs include finasteride. 3.M receptor antagonist: M receptor antagonist selectively acts on the bladder, blocking acetylcholine and mediating the contraction of the urethral muscle M receptor binding, inhibiting the involuntary contraction of the urethral muscle, so as to improve the function of the bladder urinary storage. M receptor antagonists can be applied alone when the patient is predominantly suffering from urinary storage symptoms such as urgency and frequency. Commonly used drugs in this category include tolterodine and others. Besides, botanical preparations and traditional Chinese medicines can also be used in the treatment of prostate enlargement, and in case of severe symptoms, surgical treatments and other means such as transurethral resection of the prostate can be used. To summarize, if you suffer from prostate enlargement, you should consult the doctor in time. There may be individual differences in the treatment program, do not blindly self-medication.
