Phenoxymethylpenicillin, also known as penicillin V (PcV) and penicillin VK, is an antibiotic useful for the treatment of a number of bacterial infections. [2] Specifically it is used for the treatment of strep throat , otitis media , and cellulitis . [ 2 ]
For example, the first chemically altered penicillin, methicillin, had substitutions by methoxy groups at positions 2’ and 6’ of the 6-APA benzene ring from penicillin G. [41] This difference makes methicillin resistant to the activity of β-lactamase, an enzyme by which many bacteria are naturally unsusceptible to penicillins. [44]
The aminopenicillins are a group of antibiotics in the penicillin family that are structural analogs of ampicillin (which is the 2-amino derivative of benzylpenicillin, hence the name). [1] Like other penicillins and beta-lactam antibiotics , they contain a beta-lactam ring that is crucial to its antibacterial activity.
Amoxicillin is also commonly used. He explains that within 24 hours of starting antibiotics, the infected person "is no longer contagious and should be fever-free soon after."
Amoxicillin is an antibiotic medication belonging to the aminopenicillin class of the penicillin family. The drug is used to treat bacterial infections [ 9 ] such as middle ear infection , strep throat , pneumonia , skin infections , odontogenic infections , and urinary tract infections . [ 9 ]
In addition, penicillin is available in different forms. There are different penicillin medications (penicillin G benzathine, penicillin G potassium, Penicillin G sodium, penicillin G procaine, and penicillin V) [3] as well as a number of β-lactam antibiotics derived from penicillin (e.g. amoxicillin).
Monobactam antibiotics exhibit no IgE cross-reactivity reactions with penicillin but have shown some cross reactivity with cephalosporins, most notably ceftazidime, which contains an identical side chain as aztreonam. [8] Monobactams can trigger seizures in patients with history of seizures, although the risk is lower than with penicillins.
Ampicillin and amoxicillin: These antibiotics are a part of the penicillin group of antibiotics but are effective against a broader range of organisms. [15] Amoxicillin is a derivative of ampicillin. In Dentistry, Ampicillin is sometimes used when dealing with dentoalveolar infections, when the antibiotic sensitivity patterns of the causative ...
