1, clomipramine: This is a commonly used antidepressant, but in the process of clinical use, it is found that this drug can also delay the ejaculation time of men. When clomipramine is used to treat premature ejaculation, patients need to take a certain dose before going to bed. The effective rate of treating premature ejaculation reached 58% after 8 weeks, and the effective rate could be maintained at 52% after 3 months of continuous use. After use, some patients may have mild adverse reactions such as thirst, nausea and headache, which generally do not affect the continued treatment.

2. Phenoxybenzylamine: It is an α receptor blocker. In the treatment of male premature ejaculation, the effect of delaying ejaculation time can reach 66% according to statistics. However, there is no uniform time limit for the specific treatment of patients, depending on the condition. It should be noted that the clinical use of this drug will occasionally affect the smooth ejaculation of semen in some patients.

3. Amphetamine: This is a commonly used psychoactive drug, which is usually used to treat mental depression in clinic, but some patients with premature ejaculation will play a role in prolonging the ejaculation time after being used according to the dose. The administration method is 1-2 times a day. Patients with hypertension, coronary heart disease and neurasthenia should not take it.
