[Pathogenesis and drug therapy of acute laminitis in horses: a literature review].

The research article provides a literature review focusing on the cause and drug treatments of acute laminitis in horses. It assesses the use of drugs including anticoagulants and alpha-receptor blocking agents in managing acute laminitis symptoms.

Understanding the Pathogenesis of Laminitis

• Laminitis is a painful and debilitating disorder affecting the feet of horses. The researchers highlight impaired microcirculation in the distal part of the foot as a key element in its onset. This implies that blood flow abnormalities in the horse’s hooves play a substantive role in the development of this condition.
• The review notes that thrombosis, or the formation of blood clots, frequently occurs in the foot corium—a layer of skin between the hoof and the fleshy part of a horse’s foot. This supports the importance of maintaining normal blood circulation in the foot to prevent laminitis.

Approaches to Drug Therapy for Acute Laminitis

• The researchers introduce two therapeutical principles tested for treating acute laminitis. The first involves the administration of anticoagulant drugs like heparin. Anticoagulants help control thrombosis, which is a significant issue in the pathology of laminitis.
• The second therapeutic principle employed alpha-receptor blocking agents, specifically phenoxybenzamine. These type of drugs work by improving peripheral blood flow, thus promoting better circulation in the afflicted horse’s foot.

Use of Anti-inflammatory Agents in Treatment

• The review also discusses the possibility of using anti-inflammatory agents during the initial stages of acute laminitis. This suggests that the inflammation plays a role in the disease’s pathophysiology, and controlling this inflammation may, therefore, help manage the condition.

Focus of the Literature Review

• The research zooms in on the clinical application of these various drugs in abating the symptoms of acute laminitis in horses. This indicates an interest in paving the way for more effective treatments that address not just the symptoms, but also the root cause of the disease.
