Antibiotics are routinely used in both human and animal medicine to treat many serious bacterial diseases. Their use in animals is highly regulated, and ensures better health and welfare of animals. Unfortunately, use of antibiotics over many decades has led to bacteria becoming resistant to these treatments, with antimicrobial resistance being one of the biggest future health risks for humanity.
The European Medicines Agency advocates the use of specific antibiotics for veterinary medicine. These are drugs which are classed as not critically important for human health. Unfortunately, since these drugs were often registered decades ago, with less requirements in terms of dose selection, it is highly probable that the dosage regimens fail to achieve optimal efficacy.
Our team are cross-European specialists in veterinary clinical microbiology and pharmacology and our project is focused on optimizing dosing levels; i.e. using the correct dose at the correct time, for the correct duration, of two drugs in combination: trimethoprim and sulfonamides in seven different animal species. The use of these drugs in an optimal way will both increase the likelihood of successful treatment in animals and reduce the risk of developing further antimicrobial resistance.
This project will lead to better future usage of these drugs in veterinary medicine. The use of accurate treatments will also result in lower reliance on other antibiotics which may be vital for use in human medicine.
