Anti-inflammatory drugs are a common term for antibiotics in clinical practice, including cephalosporin antibiotics, penicillin antibiotics, quinolone antibiotics, and aminoglycoside antibiotics. Which anti-inflammatory drug is good, each antibiotic its antibacterial spectrum is different, the mechanism of action is different. For example, the common surface boils and folliculitis infections are usually treated with penicillin or cephalosporin antibiotics, which mainly target Gram-positive cocci and Staphylococcus aureus with better killing effect. For abscess formation in the hepatobiliary system or appendiceal abscess, cephalosporin antibiotics of the third generation or higher are usually used because of the combination of anaerobic bacterial infections, and the treatment is more effective. And for prophylactic infection of gastrointestinal surgery, second-generation cephalosporins are usually chosen, which can take into account both Gram-positive and Gram-negative bacilli. And for simple gastrointestinal inflammation, such as colitis, quinolones or aminoglycosides are usually used, which are mainly effective against Gram-negative bacilli.
