Topic:Medication
The topic of medication in horses encompasses the study and application of pharmaceutical substances used to treat, manage, or prevent diseases and conditions in equine patients. This field involves understanding the pharmacokinetics and pharmacodynamics of various drugs, including their absorption, distribution, metabolism, and excretion in horses. Medications commonly administered to horses include non-steroidal anti-inflammatory drugs (NSAIDs), antibiotics, anthelmintics, and sedatives. The appropriate use of these medications is critical for ensuring therapeutic efficacy and minimizing adverse effects. Research in this area focuses on dosage optimization, drug interactions, resistance development, and withdrawal times to ensure both the health of the horse and compliance with regulatory standards. This page aggregates peer-reviewed studies and scholarly articles that explore the pharmacological aspects, clinical applications, and regulatory considerations of equine medications.
Recurrent convulsions in a thoroughbred foal: management and treatment. A thoroughbred foal had a convulsive attack 12 hours after birth followed by further convulsions on the 10th, 11th and 12th days after birth. It was treated successfully by medication with primidone, feeding by stomach tube and careful nursing.
Amphotericin B for the treatment of localized subcutaneous phycomycosis in the horse. Amphotericin B was used systemically or locally, or both, in the treatment of localized subcutaneous phycomycosis in horses. In 8 of 10 cases, the results were satisfactory. Intravenous treatment was well tolerated at an average starting daily dosage of 0.38 mg/kg, increasing up to as high as 1.47 mg/kg. It was concluded that the ideal treatment regimen would include early surgical removal of the lesion followed by daily intravenous and topical administration of amphotericin B, with periodic extirpation of small necrotic tracts as necessary.
Observations on development of Strongyloides westeri in foals nursing dams treated with cambendazole or thiabendazole. In 1 experiment, a prepatent period of 8 or 9 days was recorded for Strongyloides westeri in 4 pony foals raised worm-free but infected with parasitic 3rd stage larvae in the postpartum milk of a mare via gastric intubation. This is about 2 to 6 days less than the usual age that eggs of S westeri appear in the feces of naturally infected suckling foals, in central Kentucky.
In other studies, mares were treated with cambendazole or thiabendazole at 0 to 2 days after parturition and continued for 7 to 16 days. Appearance of S westeri eggs in feces of foals nursing treated mares was prevented ...
A method of ether anaesthesia in ponies. A method of inhalation anaesthesia using diethyl ether, following induction with thiopentone, is described in ponies. The high concentrations of ether needed to maintain anaesthesia were obtained by using a Marrett head in circle vaporizer. This methods would only be used in ponies, since the diameter of the tubing is too small for use on larger horses.
Veterinary aspects of doping. Doping can improve or impair performance and can be done either deliberately or accidentally. Accidental doping to win is the offence which most concerns the veterinary surgeon. The distinction between legitimate therapy and assisting an unfit horse to win a race by giving it a drug is a fine one. General guidelines are presented for the veterinary surgeon in practice.
Liver fluke infection in horses and ponies. Thirty eight cases of Fasciola hepatica infection in horses with associated clinical signs are reported. A method of examining large amounts of faeces for fluke is described. A safe method of treatment for infected horses is given which involves oral medication with oxyclozanide at a dose rate of 15 ml/50 kg body weight.
Prostaglandin F2alpha treatment of cyclic dysfunction in mares. THE ABILITY OF PROSTAGLANDIN (PG)F2a and its synthetic analogues to induce luteolysis in the mare has been adequately demonstrated (3, 6). This luteolytic effect has been utilized in the treatment of several forms of cyclic dysfunction encountered in horse breeding. It has been shown that a high proportion of Thoroughbred mares with persistent luteal function (prolonged diestrus) treated with PCF2a analogues will come into estrus within four days of treatment and that they will ovulate normally (4, 10). Thus PG treatment of mares which exhibit aberrant estrous cycles during the breeding season...
Drug interactions in the horse: effect of furosemide on plasma and urinary levels of phenylbutazone. Horses pretreated with 6.6 mg/kg of phenylbutazone were injected with 1 mg/kg of furosemide intravenously. Furosemide had no clinically significant effect on either plasma levels or plasma half-life of phenylbutazone. Furosemide reduced urinary levels of phenylbutazone 18-fold to concentrations which may result in inconsistent drug detection in routine screening tests. The results show that it is not possible to monitor compliance with phenylbutazone medication rules by means of urinalysis alone if the use of furosemide is permitted. Furosemide treatment, however, does not interfere with monit...
