Antibiotics commonly used in the treatment of prostatitis include macrolides, quinolones, sulfonamides, tetracyclines, etc. The appropriate antibacterial drugs need to be selected according to the drug sensitivity test. 1. Macrolides: Roxithromycin and azithromycin are commonly used. They have strong ability to penetrate the prostate membrane, dissociate into non-fat soluble state in acidic environment, and have higher concentration in prostate fluid. 2. Quinolones: i.e. the most common ones such as ciprofloxacin and ofloxacin. These antibiotics have strong penetration properties and a broad antibacterial spectrum, and are commonly used in the treatment of prostatitis. 3. Sulfonamides: these drugs can easily penetrate into the prostate, and are more effective in treating sensitive bacteria, and are now commonly used in the treatment of cotrimoxazole. 4. Tetracyclines: such as minocycline, prednisone, etc., on mycoplasma, chlamydia infection has a strong sensitivity. The above drugs are for reference only, the specific dosage and usage should follow the doctor’s instructions. Prostatitis should be treated in a timely manner, in accordance with the doctor’s instructions for joint medication, not blindly use drugs.
