Impotence is the common name for erectile dysfunction. Oral treatment drugs for this disease mainly include type 5 phosphodiesterase inhibitors and androgens, but the specific efficacy varies from person to person, and it may not be a complete cure. 1. Type 5 phosphodiesterase inhibitors: such as sildenafil, tadalafil, vardenafil, etc., are currently the first-line drugs used in the treatment of erectile dysfunction. These drugs are prohibited for those who are allergic to them, and also prohibited from combining with nitrate drugs such as isosorbide mononitrate, which may cause adverse reactions such as headache and flushing during the use of the drug. 2. Androgens: such as testosterone undecanoate capsules, testosterone undecanoate pills, etc., applicable to androgen deficiency patients. These drugs are prohibited for those who are allergic to them, men with suspected or confirmed prostate cancer or breast cancer, and adverse reactions include nausea, diarrhea and so on. However, it should be noted that the specific efficacy of the use of the above drugs may vary depending on the severity of the disease, personal constitution and other factors, and in addition to oral medication, androgens (such as testosterone undecanoate injection), cavernous body active drugs (such as prostaglandin), etc. are also commonly used in the treatment of erectile dysfunction, and clinically there are also psychological treatment, surgical treatment and other methods to choose from. Therefore, young patients may not be able to achieve a complete cure for erectile dysfunction after taking medication, and those diagnosed with the disease must choose medication and other treatments under the guidance of a doctor and according to the actual situation of the individual, in order to strive for a good prognosis. Do not dispose of yourself, blindly use drugs, in order to avoid improper intervention, resulting in adverse consequences.
