Rocornal is primarily used in the field of veterinary medicine as a vasodilator. It is commonly administered to horses to improve blood circulation, particularly in cases of lameness or other conditions where enhanced blood flow to the limbs is necessary. By dilating blood vessels, it helps reduce pain and inflammation, promoting faster recovery and improved mobility. Additionally, it is sometimes utilized in the management of certain cardiovascular conditions in animals, aiding in the treatment of circulatory disorders. Its application is carefully monitored by veterinarians to ensure appropriate dosing and effectiveness.
