Benzylpenicillin, also known as penicillin G (PenG [4]) or BENPEN, [5] is an antibiotic used to treat a number of bacterial infections. [6] This includes pneumonia , strep throat , syphilis , necrotizing enterocolitis , diphtheria , gas gangrene , leptospirosis , cellulitis , and tetanus . [ 6 ]
This is a list of common β-lactam antibiotics—both administered drugs and those not in clinical use—organized by structural class. Antibiotics are listed alphabetically within their class or subclass by their nonproprietary name. If an antibiotic is a combination drug, both ingredients will be listed.
Effective for gram-positive, gram-negative, anaerobic, and against multi-antibiotic resistant bacteria (such as Staphylococcus aureus [MRSA] and Acinetobacter baumannii), but not effective for Pseudomonas spp. and Proteus spp. Teeth discoloration and same side effects as tetracycline. Not to be given to children and pregnant or lactating women.
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
Using any of these, bacteria commonly develop resistance to different antibiotics, a phenomenon called multi-drug resistance. The actual process of resistance mechanism can be very complex. In case of reduced permeability in bacteria, the mechanisms are different between Gram-positive and Gram-negative bacteria.
The FDA is, however, reporting a shortage of the antibiotic amoxicillin in its oral powder form, which is mixed with a suspension to create a liquid children can swallow.
Penicillins are a widely used group of medications that are effective for the treatment of a wide variety of bacterial infections in human adults and children as well as other species. Some side effects are predictable, of which some are common but not serious, some are uncommon and serious and others are rare. [ 2 ]
