Pharmacokinetics and endometrial tissue concentrations of enrofloxacin and the metabolite ciprofloxacin after i.v. administration of enrofloxacin to mares

JOURNAL OF VETERINARY PHARMACOLOGY AND THERAPEUTICS, 25(5), 343–350.

By: M. Papich n , S. Van Camp n, J. Cole n & M. Whitacre n

MeSH headings : Animals; Anti-Infective Agents / administration & dosage; Anti-Infective Agents / blood; Anti-Infective Agents / pharmacokinetics; Area Under Curve; Chromatography, High Pressure Liquid / veterinary; Ciprofloxacin / administration & dosage; Ciprofloxacin / blood; Ciprofloxacin / pharmacokinetics; Endometrium / metabolism; Enrofloxacin; Female; Fluoroquinolones; Horses / metabolism; Infusions, Intravenous / veterinary; Quinolones / administration & dosage; Quinolones / blood; Quinolones / pharmacokinetics
TL;DR: Endometrial tissue concentrations taken from the mares after dosing showed that enrofloxacin and ciprofloxin both penetrate this tissue adequately after systemic administration and would attain concentrations high enough in the tissue fluids to treat infections of the endometrium caused by susceptible bacteria.

2001 journal article

Ovarian follicular development following administration of progesterone or aspiration of ovarian follicles in Holstein cows

THERIOGENOLOGY, 55(3), 805–821.

By: J. Cavalieri n, P. Farin*, J. Kinder, S. Van Camp*, M. Whitacre*, S. Washburn*, J. Britt* 

author keywords: ovarian follicle aspiration; FSH; progesterone; synchronization; ultrasonography
MeSH headings : Animals; Biopsy, Needle / veterinary; Cattle / physiology; Dinoprost / pharmacology; Estradiol / blood; Estrus; Estrus Synchronization / blood; Female; Follicle Stimulating Hormone / blood; Ovarian Follicle / drug effects; Ovarian Follicle / growth & development; Ovary / diagnostic imaging; Ovulation; Progesterone / pharmacology; Ultrasonography
TL;DR: Both the administration of P4 and the aspiration of follicle aspiration on Day 7 of the estrous cycle improves the synchrony of ovulation when luteolysis is induced on Day 11 and results in similar concentrations of FSH at the time of follicular wave emergence, but the timing of wave emergence and the number of follicles post-emergence differ.

Administration of ticarcillin in combination with clavulanic acid intravenously and intrauterinely to clinically normal oestrous mares

JOURNAL OF VETERINARY PHARMACOLOGY AND THERAPEUTICS, 23(6), 373–378.

TL;DR: It appears that addition of clavulanate to the formulation for treatment of i.u. infections in mares is of questionable value based on these concentrations, which would necessitate frequent treatment in order to maintain drug concentrations above the minimum inhibitory concentrations (MIC) throughout the treatment period.
