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
The BNF for Children developed from the British National Formulary (BNF), which prior to 2005 had provided information on the treatment of children, with the doses largely determined by calculations based on the body weight of the child. The guidance was provided by pharmacists and doctors whose expertise was in the care of adults.
Narrow-spectrum antibiotics have low propensity to induce bacterial resistance and are less likely to disrupt the microbiome (normal microflora). [3] On the other hand, indiscriminate use of broad-spectrum antibiotics may not only induce the development of bacterial resistance and promote the emergency of multidrug-resistant organisms, but also cause off-target effects due to dysbiosis.
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 ]
Porins are large enough to allow diffusion of most penicillins, but the rate of diffusion through them is determined by the specific size of the drug molecules. For instance, penicillin G is large and enters through porins slowly; while smaller ampicillin and amoxicillin diffuse much faster. [50]
Many antibacterial compounds are relatively small molecules with a molecular weight of less than 1000 daltons. [80] Since the first pioneering efforts of Howard Florey and Chain in 1939, the importance of antibiotics, including antibacterials, to medicine has led to intense research into producing antibacterials at large scales.
The average body weight of women in America has been steadily increasing over the past few decades. According to national surveys, about 42 percent of U.S. women have obesity and an additional 27 ...
Clark's rule is a medical term referring to a mathematical formula used to calculate the proper dosage of medicine for children aged 2–17 based on the weight of the patient and the appropriate adult dose. [1] The formula was named after Cecil Belfield Clarke (1894–1970), a Barbadian physician who practiced throughout the UK, the West Indies ...
