Use of pharmacological agents to aid management of ejaculatory and behavioral dysfunctions in stallions

Abstract

All stallions here were successfully collected after the adjustments and described medication. In some cases, a combination of different drugs was used to collect. Case 1, phenylbutazone was used for suspected orthopedic pain in combination with imipramine, a tricyclic drug known to decrease the threshold for ejaculation (cases 1 and 6) and to promote closure of the bladder neck (case 2). Benzodiazepine (diazepam and midazolam), anxiolytics and anti-depressants were used to promote libido (cases 3,4,6) and to decrease anxiety in a high libido horse stallion (case 6) afraid to mount, either due to previous bad handling experiences or punishments. We foresee that the discussion of the present case series will be of interest as continuing education for clinicians and trainees.
