Treatments for horses encompasses a range of medical and therapeutic interventions aimed at maintaining or restoring equine health. This field involves the use of pharmaceuticals, surgical procedures, and alternative therapies to address various conditions affecting horses. Common treatments include the administration of anti-inflammatory drugs, antibiotics, and vaccines, as well as physical therapies and nutritional management. Research in this area focuses on evaluating the efficacy, safety, and outcomes of different treatment modalities. This page collects peer-reviewed research studies and scholarly articles that explore the methods, advancements, and clinical outcomes associated with equine treatment practices.
Bishop WJ.GG is a useful sedative and anaesthetic agent in horses. Used
alone, or in conjunction with barbiturates, it produces a un-
iformly smooth recovery from anaesthesia.
The need to infuse large volumes to obtain the desired effect is
a disadvantage ofthis agent. Few critical studies have been made
on the short and long term effects of administration of GG to
horses. Its pharmacology and clinical use are described and
indicate that it is a safe and useful drug.
Allen WE, Clarke AR.Plasma concentrations of sodium benzylpenicillin following intrauterine infusion were increased by reducing the volume of solution and expelling air from the vagina after infusion. Instillation of 10 per cent Lugol's iodine solution into the uterus before penicillin infusion further increased the absorption rate, although peak plasma levels of penicillin were less than half those which resulted from intramuscular injection of the same dose.
David JS, McCullagh KG.A large anastomosis of the spermatic artery and vein is described. This was found while surgically removing an abdominal testis. Before surgery the animal wanted to rear after exercise and could not stand on 3 legs for any length of time while being shod. This unusual behaviour disappeared after removal of the mass. The performance and conformation of the horse has also greatly improved.
Edwards GB.Results of the clinical and radiographic examination of 8 lame horses with tarsal sheath distension are described. In chronic cases pathological exostoses were identified radiographically in the sustentaculum tali and were demonstrated at post mortem in 4 of the horses which were destroyed. The prognosis and the feasibility of treatment are discussed in the light of these changes and the associated damage found at post mortem in the deep flexor tendon and its sheath. Trauma to the hock was known to have occurred in half the cases and was suspected in the others.
Denny HR.The current trends in equine fracture treatment are reviewed. Surgical approach, method of fixation, the advantages of Association for the Study of Internal Fixation (ASIF) implants and the complications of treatment are discussed with reference to 21 fracture cases. Normal limb function was restored in four horses with fractures of the olecranon and one with a mid shaft fracture of the tibia following stabilisation of the fracture with plates. A horse with a chip fracture of the distal radius and three other animals with fractures of the lateral condyle of the third metacarpal bone were also ...
McBeath DG, Best JM, Preston NK, Duncan JL.Examination of faecal egg counts in horses and ponies has shown that after treatment with fenbendazole at dose levels of 7.5, 45 and 60 mg/kg, faeces remained free from strongyle eggs for periods of 6 to 18 weeks. The significance of these results is discussed in relation to routine anthelmintic treatment of horses. In particular, the activity of fenbendazole against mucosal stages of strongyle parasites allows for treatment to be recommended at less frequent intervals than when using other anthelmintics.
Sasse HH, Hajer R.The manufacturers state that NAB 365 is a beta2-receptor-stimulating sympathicomimetic agent. According to the medical literature it combines a bronchial antispasmodic effect with certain bronchia secretolytic properties and has few untoward side-effects on, for instance, the heart and intestine. The effectiveness of administration of NAB 365 in horses with chronic or acute respiratory disease was tested in the Department of Veterinary Internal medicine in Utrecht. NAB 365 administered at a dosage of 0.8 gamma/kg, of body weight was found to have a marked bronchodilative effect in horses. Ther...
Böhm D, Waibl H.Of 28 fractures of the first phalanx 21 were treated with osteosynthesis; one was treated conservatively. 2 to 4 compression screws have been applied, while the distal part of the limb was immobilized by a light cast bandage for 8 days. The implants were removed 2 to 3 months post operationem. All patients are again used in sports.
Yoxall AT.The principles of radiological protection are summarised and consideration is then given to problems, which may confront the equine practitioner, in the fulfillment of these principles during diagnostic radiography of the limbs, head, and spine of the horse. The place of anaesthesia in such procedures is discussed and the special problems associated with therapeutic radiography of the horse are considered.
Strömberg B, Tufvesson G.Four autologous tendon grafting techniques, bipedicle, pedicle and free grafts of the deep digital flexor tendon and free grafts from the lateral digital extensor tendon were described. The vascularization and remodelling of the transplant and the reactions in the donor, as well as the recipient tendon, were studied by means of microangiographic and histochemical methods. The results indicated that regardless of the technique used the grafts were revascularized and replaced by a highly orientated and organized tendon. The use of free grafts may therefore be worthwhile in treatment of severe te...
Bras GE, Kersjes AW.Comparative studies were done on healing of the wound following laparotomy through the ventral wall of the abdomen (paramedian incision or in the linea alba) in seventy horses and following surgical treatment of umbilical hernia in eighty-five (young) horses, in which perlon, (chromic) catgut, stainless steel wire and polyglycollic acid were used as suture material. Though with some reserve, as the study was concerned with the comparison of findings in clinical cases in which a number of conditions may vary, it is concluded that steel wire and polyglycollic acid are preferable to perlon and (c...
Hoffer RE, Barber SM, Kallfelz FA, Petro SP.Esophageal patch grafting, using the sternocephalicus muscle, was used for treatment of cervical esophageal stricture in a mare. The mare was maintained during the initial healing phase by total parenteral nutrition.
Frost GE, du Preez HR.A 3 year old thoroughbred colt in full training pulled up
acutely lame during a training gallop on a dirt track.
According to the trainer no reason for the injury was
evident. The horse refused to bear weight on the leg
and when forced to walk back to the stables it would
only touch the affected toe to the ground. The fetlock
soon became swollen and was very painful. The trainer
treated the animal for a sprain with ice packs and
bandages. No improvement occurred in 72 hours and
veterinary advice was sought.
Examination revealed the horse to be in obvious
pain. He was unable to bear ...
Hilbert BJ, Farrell RK, Grant BD.Squamous cell carcinoma around the eyes of 3 horses was treated with liquid nitrogen, using cryotherapy probes as the method of application. In 2 cases, there was complete regression of the tumor; in the 3rd case, remission and relief of discomfort were temporary.
McMullan WC, Joyce JR, Hanselka DV, Heitmann JM.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.
Lyons ET, Drudge JH, Tolliver SC.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 ...
Sanders RK, Martyn B, Joseph R, Peacock ML.In a two-year study of 322 conservatively treated, consecutive cases of tetanus in a rural hospital (all over twelve months old), intrathecal administration of 200 units of antitetanus serum (A.T.S.) (horse) reduced the overall mortality of 4-5% (5/110) compared with 14-5% (16/111) in the control series. 200 units intrathecal A.T.S. (horse) gave better results than 1500 units A.T.S. (horse). The results with lumbar and cisternal administration did not differ. It is suggested that tetanus is a polysystemic condition requiring polysystemic therapy. A regimen in which intrathecal A.T.S. is given ...
Spadari A, Saragoni G, Meistro F, Ralletti MV, Marzari F, Rinnovati R.This case report documents an unusual cheek tooth (CT) displacement in a 3-year-old Arabian filly. The horse was referred to the clinic for loss of appetite and right-sided facial deformity. At admission, an oral inspection was performed, followed by a dental radiographic examination. The radiographs showed a very oblique vertical angulation (135°) of the CT 106 compared to the other premolars (107 and 108 CTs) (40°). In consideration of the clinical and radiographic findings, surgical extraction of the 106 CT was indicated. Due to the unique positioning of the displaced tooth, traditional e...
Hefner EM, Stoppini R, McMullen RJ. This study is aimed at describing two unique case presentations of iris hypoplasia and the use of semiconductor diode laser for treatment in the horse. One 20-year-old American Quarter Horse gelding and one 11-year-old pony mare were studied. The presenting clinical signs, surgical technique, and postoperative results for two cases of iris hypoplasia treated with diode laser are described. Immediate postoperative complications-postoperative ocular hypertension (POH), corneal edema, and epithelial bullae-were possible anticipated effects but were controlled with topical medications in the fi...
Quinn CT.Catheterisation of the urinary bladder is a common procedure during perioperative care of horses. Benefits of urinary catheters include a reduction in the risk of recovery-associated slip hazards as a consequence of voided urine and the measurement of urine output during anaesthesia. However, there is little information regarding the risks associated with this procedure. A retrospective cohort study was undertaken in horses admitted to a university teaching hospital for surgery during which a urinary catheter was placed perioperatively. Data were retrieved from clinical records including signa...
Debald DC, Stanton VL, Sandow CB, Rodgerson DH, Spirito MA, Hunt RJ, Menarim BC.While radiographically evident carpal osteochondral fragments (COF) in Thoroughbred yearlings impair sales, their impact on future racing performance has been minimally investigated. Objective: To assess the impact of COF on Thoroughbred yearling sales and racing performance, and whether these are improved by arthroscopic removal. We hypothesised that surgical removal of COF improves Thoroughbred yearling sales and racing performance. Methods: Retrospective observational. Methods: Using clinical records from years 2015-2018, 46 Thoroughbred yearlings with COF were identified and allocated to a...

Connolly KM, Estell K.Dysphagia describes a clinical sign of pathologies of the oral cavity, pharynx, and oesophagus that carries potentially serious consequences for horses. Given the diversity of differential diagnoses that may cause dysphagia, an understanding of the prevalence of dysphagia in hospitalised patients, the distribution of aetiologies and clinical outcomes could inform diagnosis, treatment, and prognosis. Objective: This study aims to describe the incidence, signalment, history, aetiology, treatment, and outcome of horses presenting to a referral hospital for dysphagia. Methods: Retrospective case s...
Luque RM, Henderson B, McCorkell TC, Alizadeh AH, Russell KA, Koch TG, Koenig J.Mesenchymal stromal cells (MSCs) are widely used to treat osteoarthritis (OA). Optimising dose, timing, and safety while comparing efficacy with standard therapies like hyaluronic acid (HA) is essential for their standardisation. Objective: To assess the safety and efficacy of equine umbilical cord-derived (eCB) MSCs in client-owned horses with fetlock or carpus OA. Methods: Prospective single-blinded randomised clinical study. Methods: Horses diagnosed with fetlock or carpus OA via intra-articular (IA) anaesthesia were randomly assigned to receive either 10 or 20 million eCB-MSCs in HA or 3â€...
Beck AA, Paz LB, Frank MI, Pereira RCF, De La Côrte FD.To evaluate the effect of IA injections of botulinum toxin type A (BoNT-A) in horses with chronic, naturally occurring distal tarsal osteoarthritis. Unassigned: 9 horses were selected after physical and radiographic assessments. Horses also underwent an objective lameness examination and were included if they had a hindlimb impact lameness (Pmin ≥ 3 mm), which positively responded (≥ 50%) to the tarsometatarsal and centrodistal joints' anesthetic block. Horses randomly received an intra-articular injection of BoNT-A or an equivalent volume of saline solution. Horses were reevaluated at pos...
Bacon EK, Donnelly CG, Finno CJ, Haase B, Velie BD.Multimodal analgesic administration is a promising strategy for mitigating side effects typically associated with analgesia; nevertheless, variation in analgesic effectiveness still poses a considerable safety concern for both horses and veterinarians. Pharmacogenomic studies have started delving into genetic influences on varying drug effectiveness and related side effects. However, current findings have narrow implications and are limited in their ability to individualize analgesic dosages in horses. Hydromorphone and detomidine were administered to a cohort of 48 horses at standardized time...
Himmele M, Engl JPM, Schwarz BC.The present report describes an 8-week-old warmblood foal presented following two episodes of epistaxis. The foal had a history of an umbilical infection, which had been treated with antibiotics when it was 8 days old. Four days before admission the filly showed severe, self-limiting epistaxis. The second hemorrhage occurred on the day of admission. The foal was lethargic and the remainder of the clinical examination unremarkable. A latero-lateral radiograph of the head revealed a fluid line within the guttural pouch. Endoscopy showed large amounts of blood within the pharynx and the upper thi...
Munsterman AS, Dias Moreira AS, Kottwitz J.To evaluate the effects of detomidine on equine intestinal slow-wave activity and frequency distribution measured by electrointestinography (EIG). Methods: Prospective, experimental study. Methods: University teaching hospital. Methods: A convenience sample of twelve 7- to 21-year-old clinically normal horses. Methods: Horses were randomly assigned to saline control (four horses) or detomidine treatment (eight). After obtaining a 30-min baseline EIG, a saline or detomidine bolus was administered, followed by a constant rate infusion, and another EIG was recorded. Ultrasonographic examinations ...
Conrad MB, Leatherwood JL, Paris BL, George JM, Martinez RE, Vergara-Hernandez FB, Nielsen BD, Colbath AC, Arnold CE, Glass KG, Welsh TH, Bradbery AN.Extra-label bisphosphonate (BP) use in juvenile horses is anecdotally reported, primarily for analgesic effects, despite the limited scientific understanding of biologic impacts on skeletally immature horses undergoing exercise. The objective of this study was to determine the effects of clodronate disodium (CD), a form of BP, on endocrine regulators of calcium. Thus, 32 yearling Quarter Horses were stratified by age (500 ± 13 d), body weight (BW; 336 ± 26 kg), sex (n = 16 geldings, n = 16 fillies), and initial bone optical density into 1 of 4 treatment groups for a 168-d tr...
Albanese V, Straticò P, Fischer H, Petrizzi L.Injuries to the distal limb are common in horses. The clinical aspect of the lesions is variable based on the structures that are involved. Synovial structures as well as tendons and/or ligaments may be involved in such injuries, affecting treatment modalities and costs, and prognosis. This retrospective study compares wounds involving synovial structures to wounds without such involvement in terms of treatment duration and costs, and prognosis. Synovial wounds were much more expensive to treat and carried a lower prognosis. Involvement of tendons and/or ligaments in the wounds resulted in mor...
Shokry M, Ali LB, El-Sharkawy M.Showjumping athletic horses are frequently affected by back pain, which in turn influences their performance and equestrian activities. Unassigned: The aim of the present study was to determine the etiological factors predisposing to back problems in show jumping horses and how to diagnose, and manage them. Unassigned: A total of 75 cases (45 geldings and 30 mares, aged between 8 and 23 years and weighing 420-550 Kg) with histories suggestive of back problems and low competitive ability as show jumping were used in this study. The evaluation of data was based on the inputs of case history, cli...

Horses presented with moderate lameness and marked effusion of the affected metatarsophalangeal joint. Fractures had a medial bias extending from the central aspect of proximal P1 to involve the dorsomedial prominence. F...
Bernick A, Krohn J, Wehrend A.Patent urachus is a common disease in newborn foals. However, despite its frequency, studies investigating symptoms, comorbidities, treatment and prognosis in a large number of affected foals have rarely been conducted. This study aimed to describe the clinical symptoms, laboratory diagnostic findings and prognosis of foals with patent urachus. Data from 101 foals with a patent urachus from 2006 to 2017 were analysed. Patent urachus occurred at a frequency of 7.8% of all foals up to the 14th day of life during the study period. More colts (74.3%) than fillies (25.7%) were affected. In those wi...
Bardhi A, Lanci A, Mannini A, Castagnetti C, Barbarossa A.Background: Although antibiotic resistance is a well-known issue in veterinary medicine, studies proposing real-time therapeutic monitoring (TDM) are lacking. The objective of the present study was to develop a simple and rapid protocol for the real-time therapeutic monitoring of antibiotics in horses and dogs. Methods: A reliable TDM protocol should encompass guidelines for the definition of plasma/serum collection time points, sample management by the clinical staff, transportation to the laboratory, and the availability of robust and swift analytical technologies. Ampicillin and sulbactam w...
Hallman IAM, Raekallio MR, Karikoski NP.Vatinoxan is a peripherally acting alpha2-adrenoceptor antagonist used in veterinary medicine to attenuate the side effects of alpha2-adrenoceptor agonists. Vatinoxan also increases insulin response and reduces blood glucose (BG) after intravenous glucose in other species. The aim of this study was to investigate the effects of vatinoxan on BG and insulin concentration in horses after intravenous glucose. The design was an assessor-blind cross-over study. Nine horses were assigned to intravenous vatinoxan (0.2 mg/kg; VAT) or saline (SAL). Horses were administered an intravenous glucose bolus (...
Bouquet A, Nicol C, Knowles EJ, Schofield I, Menzies-Gow NJ.Clinical signs of pituitary pars intermedia dysfunction (PPID) are frequently mistaken for 'normal' ageing and may not be optimally assessed.

Lam KP, Keys DA, McMullen RJ.To describe infracyanine green-based photodynamic therapy (InfraCG-PDT) and evaluate outcomes in horses with immune-mediated keratitis (IMMK). Methods: Medical records from 2014 to 2020 from the Equine Clinic Munich-Riem, Germany, and Auburn University Equine Ophthalmology Service identified horses diagnosed with IMMK following ophthalmic examination that had undergone InfraCG-PDT. Methods: Multiple intrastromal injections of EmunDo (InfraCG, A.R.C. Laser, Nuernberg, Germany) within an affected quadrant or the entire cornea were treated with diffuse diode laser energy (FOX A.R.C., Laser, Nuern...
Warren AS, Werner LA, Thombs LA, Rodgerson DH, Spirito MA, Sandow CB, McCracken MJ.To report the impact of ventral midline colopexy on colic, recurrence of large colon volvulus (LCV) and time to next live foal. Methods: Retrospective case control study. Methods: A total of 188 Thoroughbred broodmares surgically treated for LCV (2016-2020). Methods: Horses treated for LCV were grouped based on whether they received a colopexy (CP) or did not (NCP). All broodmares that underwent a second LCV surgery were subsequently categorized into two groups: those that received a colopexy (RCP) and those that did not (NRCP). Differences in the number of horses with large colon compromise, ...
Wright JP, Gray SM, Bishop RC.To describe and demonstrate the collection of abdominal fluid from a standing, sedated equine patient. Unassigned: 1 healthy university-owned animal was used for abdominocentesis demonstration. Images from various clinical cases from the University of Illinois Veterinary Teaching Hospital are shown. Unassigned: Under standing sedation, a 10 X 10-cm area is clipped and aseptically prepared on the most dependent portion of the abdomen to the right of midline. One to 2 mL of 2% lidocaine is instilled subcutaneously and into the abdominal musculature at the abdominocentesis site. A stab incision i...
Reinthaler B, Gabner S, Apprich V, Jehle M, Licka T.Equine hoof canker is a chronic proliferative condition of the hoof tissues that is often time-consuming and frustrating to treat. After surgical debridement, topical application of cisplatin (cis-Diamindichlorplatin II) has been reported, requiring repeatedly handling this hazardous substance during bandage changes. Alternatively, intraarterial application of cisplatin could be used, similar to the treatment of some human neoplastic diseases. As the side effects of such a treatment are currently unknown, evaluation of associated risks is necessary before treating live horses. Thus, forelimbs ...
Serpa PBS, Bogers S, Byron C, Cardona G, Patton M.A 1-year-old American Quarter horse was presented with acute onset of right hind lameness. On physical examination, there was synovial effusion of the right tarsocrural joint. Synovial fluid cytology revealed a marked eosinophilic synovitis. Serology indicated evidence of acute and chronic infection with Borrelia burgdorferi, although PCR of the synovial fluid was negative. The filly was treated with phenylbutazone and oxytetracycline, and repeated synovial cytology indicated improvement. The filly was discharged with a prescription of minocycline for 30 days. Despite initial improvement, recu...
Berner D, Hellige M, Harvey GG, Gerlach K, Iglesias-Garcia M, Manso-Diaz G.Paranasal sinus cysts (PSC) and progressive ethmoid haematomas (PEH) are regularly observed in the paranasal sinus system. Due to their different prognosis and treatment options, differentiation of both lesions prior to surgery on computed tomographic (CT) images is important for guidance. It was hypothesised that PSC and PEH can be reliably differentiated on CT images. The database of four European equine referral centres were retrospectively searched for horses that had undergone a CT examination of the head and had a confirmed PSC or PEH. Additionally, cases with confirmed sinusitis were se...
Birkmann K, Waldern N, Jucker S, Balaschitsch K, Zablotski Y, Fettelschoss-Gabriel A.Recurrent urticaria is common in horses. The pathophysiology is poorly understood and treatment options are limited. Often, only glucocorticoids are effective for controlling clinical signs, albeit with potential adverse effects. Studies investigating new treatments need a validated objective scoring system for the grading of skin lesions to assess response. Objective: The aims were to investigate inter- and intraobserver reliability of the Equine Urticaria Activity Score (EqUAS) for the grading of skin lesions in horses with recurrent urticaria, and to examine agreement between experienced an...
van der Merwe LM, Schliewert EC.Colic is a common equine emergency requiring medical or surgical intervention. These interventions can be costly, making outcomes data and prognostic indicators essential for guiding referral and treatment decisions. Objective: To determine survival rates to hospital discharge and evaluate prognostic indicators in equine colic cases treated at a referral hospital (Onderstepoort Veterinary Academic Hospital [OVAH], South Africa). Methods: This retrospective observational cohort study analysed records from horses with colic that were presented to the OVAH from January 2019 to August 2021. Data i...
Ho HSM, Mizzi JX, Ho ENM, Wong WT.Ranitidine is a histamine H-receptor antagonist commonly used to treat gastric ulceration in horses. The author's laboratory conducted a study some years ago in the early 2000s on its metabolism as well as its urinary elimination profile in two geldings. With the technology advancement as well as popularity of blood for doping control testing, the laboratory has recently conducted another administration trials of the substance in six horses to study the in vivo metabolism of ranitidine, aiming to identify and reinvestigate the appropriate target(s) for controlling misuse of ranitidine in hors...
Stuart RB, Miles-Farrier F, Bard AM, Rees G.Antimicrobial resistance (AMR) is an increasingly serious threat to human and animal health. Antimicrobial use (AMU) in horses is gathering research interest, although there remain significant evidence gaps. Currently, there is scant qualitative research into equine owners' use of antimicrobials, specifically antibiotics, hindering the design of evidence-based stewardship interventions and policies. Objective: To understand Welsh equine owners' views and behaviours relating to antimicrobial usage. Methods: Cross sectional survey and qualitative data collection and analysis. Methods: An online ...
