Method 1: antibiotics: oral tetracycline, erythromycin, roxithromycin, minocycline (minocycline) can significantly reduce the concentration of free fatty acids in sebum, inhibit the chemotactic activity of acne propionate and leukocytes.

Method 2: tetracycline: 0.5-1 g / D, reduced according to the therapeutic response, maintained at 0.25 g / d. It is effective for moderate and severe papular pustular acne. Oral erythromycin has gastrointestinal irritation, so it is generally not advocated to take. Clindamycin (clindamycin) and clindamycin (clindamycin) were commonly used in the past, but they may produce pseudomembranous colitis, so they are rarely used in recent years.

Method 3: doxycycline (deoxytetracycline, doxycycline): the drug effect is better than tetracycline. Drug resistance is rare. The first dose was 0.2g, then 0.1-0.2g/time, once a day. However, the drug is easy to produce photosensitivity and should not be taken in summer.
