Dog medications dosage requirements are generally calculated by weight and measured in mg of medicine per pound of body weight. It's hugely important to get make sure that your dog gets exactly the right dose of medicine, at the correct time intervals. Too little medicine could mean that it won't work properly, too much could cause side-effects, potentially life-threatening ones. The charts below features many of the most commonly prescribed dog medications as well as several over-the-counter products which are routinely used to treat dogs. However, please don't give your dog any medicine or product without first checking with your vet to make sure that it's safe for YOUR dog. Example: Dog medication dosage for Amoxicillin is between 5mg and 10 mg per lb. So, the correct dosage of Amoxicillin for a 10lb dog would be a minimum of 50mg and a maximum of 100mg. When dosage and/or frequency is flexible your veterinarian will be able to tell you which end of the scale Some medicines are not safe for use by some dogs, or by those who have specific health conditions. The design of a dosing regimen begins with an assessment of the minimal inhibitory concentration (MIC) of the antibacterial agent for a particular pathogen. Depending on the antimicrobial, plasma or tissue drug concentrations should either markedly exceed the MIC by 10- to 12-fold (for concentration [sometimes referred to as dose-dependent antimicrobials], such as the aminoglycosides and the fluorinated quinolones) or be above the MIC (T], sulfonamides, and most “bacteriostatic” drugs). To compensate for drug disposition to tissue sites and the effect of host factors on antibiotics, dosages for most drugs should result in plasma drug concentrations several times higher than the calculated concentration-dependent or time-dependent MIC in the infected tissues or fluids. For dose-dependent drugs, efficacy is enhanced by increasing the dose; for time-dependent drugs, therapeutic efficacy is enhanced by increasing the dose and shortening the dosing interval or by choosing a drug with a long half-life. In today’s infectious disease environment, appropriate design of a dosing regimen should depend not on labeled doses, but rather on access to information regarding the current pharmacodynamics of the infecting microbe (ie, MIC from the pathogen cultured from the patient, or the MIC of a sample population of the pathogen collected from the target animal) and the pharmacokinetics of that drug in the target species. Appropriate pharmacokinetic parameters on which the dosing regimen should be designed include maximum plasma concentration, or C and drug elimination half-life for time-dependent drugs. Supportive information for design of dosing regimens often can be found in the literature.
Amoxicillin is a penicillin antibiotic that is used to treat a wide variety of infections in dogs, cats, and other species. Here's what you need to know about it. Learn about the veterinary topic of Dosing Regimens. Find specific. The half-life of amoxicillin is only 1–1.5 hr, indicating that dosing should occur every 3 hr.
