The minimum inhibitory concentration (MIC) and minimum bactericidal concentration are used to measure in vitro activity of antimicrobial agents. They are good indicators of antimicrobial potency, but don't give any information relating to time-dependent antimicrobial killing (the so-called post antibiotic effect).
The bactericidal activity of marbofloxacin is concentration dependent, with susceptible bacteria cell death occurring within 20–30 minutes of exposure. Like other fluoroquinolones, marbofloxacin has demonstrated a significant post-antibiotic effect for both gram– and + bacteria and is active in both stationary and growth phases of bacterial ...
Drugs come with a recommended dose in milligrams or micrograms per kilogram of body weight, and that is used in conjunction with the patient's age and body weight to determine a safe dose. In single-dose scenarios, the patient's body weight and the drug's recommended dose per kilogram are used to determine a safe one-time dose.
Enrofloxacin, sold under the brand name Baytril, among others, is a fluoroquinolone antibiotic used for the treatment of animals. [1] It is a bactericidal agent. [1]The bactericidal activity of enrofloxacin is concentration-dependent, with susceptible bacteria cell death occurring within 20–30 minutes of exposure.
Due to the dependence on the length of x in the trapezoidal rule, the area estimation is highly dependent on the blood/plasma sampling schedule. That is, the closer time points are, the closer the trapezoids reflect the actual shape of the concentration-time curve.
Depending on the pathogen and antibiotics being tested, the media can be changed and/or adjusted. The antimicrobial concentration is adjusted into the correct concentration by mixing stock antimicrobial with media. The adjusted antimicrobial is serially diluted into multiple tubes (or wells) to obtain a gradient. The dilution rate can be ...
The AUC (from zero to infinity) represents the total drug exposure across time. AUC is a useful metric when trying to determine whether two formulations of the same dose (for example a capsule and a tablet) result in equal amounts of tissue or plasma exposure. Another use is in the therapeutic drug monitoring of drugs with a narrow therapeutic ...
Topics of pharmacodynamics. Pharmacodynamics (PD) is the study of the biochemical and physiologic effects of drugs (especially pharmaceutical drugs).The effects can include those manifested within animals (including humans), microorganisms, or combinations of organisms (for example, infection).
