The following is a list of antibiotics. The highest division between antibiotics is bactericidal and bacteriostatic. Bactericidals kill bacteria directly, whereas bacteriostatics prevent them from dividing. However, these classifications are based on laboratory behavior. The development of antibiotics has had a profound effect on the health of people for many years. Also, both people and animals have used antibiotics to treat infections and diseases. In practice, both treat bacterial infections.
By coverage
The following are lists of antibiotics for specific microbial coverage (not an exhaustive list):
MRSA
Antibiotics that cover methicillin-resistant Staphylococcus aureus (MRSA): Vancomycin Teicoplanin Linezolid Daptomycin Trimethoprim/sulfamethoxazole Doxycycline Ceftobiprole (5th generation) Ceftaroline (5th generation) Clindamycin Dalbavancin Delafloxacin Fusidic acid Mupirocin (topical) Omadacycline Oritavancin Tedizolid Telavancin Tigecycline (also covers gram negatives)
Pseudomonas aeruginosa
Antibiotics that cover Pseudomonas aeruginosa:
Certain cephalosporins, cephalosporin-beta-lactamase-inhibitor combinations, and new siderophore cephalosporins. Ceftazidime (3rd generation) Cefepime (4th generation) Ceftobiprole (5th generation) Ceftolozane/tazobactam Ceftazidime/avibactam Cefiderocol(siderophore cephalosporin)
Certain penicillins: Piperacillin and Piperacillin/tazobactam Ticarcillin/clavulanic acid
Certain carbapenems and carbapenem-beta-lactamase-inhibitors combinations: Carbapenems: (meropenem, imipenem/cilastatin, doripenem - NOT ertapenem) Meropenem/vaborbactam Imipenem/cilastatin/relebactam
Others: Fluoroquinolones: particularly levofloxacin, ciprofloxacin Polymyxins: Colistin, Polymyxin B Aztreonam (monobactam) Aminoglycosides - particularly tobramycin and amikacin
VRE
Antibiotics that usually have activity against vancomycin-resistant Enterococcus (VRE): Linezolid and Tedizolid Streptogramins such as quinupristin-dalfopristin Advanced generation tetracyclines: Tigecycline, Omadacycline, Eravacycline Daptomycin Oritavancin
Antibiotics with less reliable but occasional (depending on isolate and subspecies) activity: occasionally penicillins including penicillin, ampicillin and ampicillin-sulbactam, amoxicillin and amoxicillin-clavulnate, and piperacillin-tazobactam (not all vancomycin-resistant Enterococcus isolates are resistant to penicillin and ampicillin) occasionally doxycycline and minocycline occasionally fluoroquinolones such as moxifloxacin, levofloxacin, and ciprofloxacin
