Tripelennamine
Tripelennamine is a histamine H1-receptor antagonist. Tripelennamine effectively reverses histamine-induced bronchoconstriction, increased transpulmonary pressure, elevated pulmonary vascular resistance and reduced dynamic compliance. Tripelennamine does not significantly affect arterial hypoxemia, hemoglobin desaturation and hypercapnia in horses undergoing short-term high-intensity exercise. Tripelennamine exhibits local and central analgesic activity. Tripelennamine can be used in studies related to emphysema, urticaria and acute laminitis.

Animal Model:Thoroughbred (3 fillies, 4 geldings, 3-6 yr old, 460 kg)[1]
-
Dosage:1.10 mg/kg
-
Administration:i.v.; single dose 15 minutes preexercise
-
Result:Caused central nervous system excitement, significant tachycardia, systemic and pulmonary hypertension, and raised hemoglobin concentration from 12.7 g/dl to 17.7 g/dl.
Increased mixed venous blood O2 tension and hemoglobin-O2 saturation, and increased arterial and mixed venous blood O2 content with no change in arterial-to-mixed venous O2 content gradient.
Increased core temperature during exercise to 41.2°C at 120 seconds of galloping (vs.
40.7°C in controls).
Showed no statistically significant differences from controls in exercise-induced arterial hypoxemia (arterial O2 tension at 120 seconds of galloping: 71.3 Torr vs.
71.3 Torr), arterial hemoglobin-O2 saturation (80.6% vs.
83.8%), arterial CO2 tension (60.1 Torr vs.
56.2 Torr), arterial pH (7.040 vs.
7.090), arterial and mixed venous blood O2 content, arterial-to-mixed venous O2 content gradient (22.8 mL O2/dl blood vs.
23.2 mL O2/dl blood), or O2 extraction (92.2% vs.
91.5%).
Resulted in exercise-induced pulmonary hemorrhage in all treated horses, matching control rates.
