Side effects in adults. Common adverse drug reactions (≥ 1% of people) associated with use of the penicillins include diarrhea, hypersensitivity, nausea, rash, neurotoxicity, urticaria (hives), and superinfection (including candidiasis ). Infrequent adverse effects (0.1–1% of people) include fever, vomiting, erythema, dermatitis, angioedema ...
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. [ 1][ 2] They may either kill or inhibit the growth of bacteria.
Tetracyclines are a group of broad-spectrum antibiotic compounds that have a common basic structure and are either isolated directly from several species of Streptomyces bacteria or produced semi-synthetically from those isolated compounds. [ 1] Tetracycline molecules comprise a linear fused tetracyclic nucleus (rings designated A, B, C and D ...
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 for children and pregnant or lactate women.
Penicillins ( P, PCN or PEN) are a group of β-lactam antibiotics originally obtained from Penicillium moulds, principally P. chrysogenum and P. rubens. Most penicillins in clinical use are synthesised by P. chrysogenum using deep tank fermentation [ 2] and then purified. [ 3][ 4] A number of natural penicillins have been discovered, but only ...
It is a combination consisting of amoxicillin, a β-lactam antibiotic, and potassium clavulanate, a β-lactamase inhibitor. [ 5] It is specifically used for otitis media, streptococcal pharyngitis, pneumonia, cellulitis, urinary tract infections, and animal bites. [ 5] It is taken by mouth or by injection into a vein.
A broad- spectrum antibiotic is an antibiotic that acts on the two major bacterial groups, Gram-positive and Gram-negative, [ 1] or any antibiotic that acts against a wide range of disease-causing bacteria. [ 2] These medications are used when a bacterial infection is suspected but the group of bacteria is unknown (also called empiric therapy ...
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.
