What is Dimalgin?
Injection is an analgesic drug used to relieve severe pain and reduce fever in dogs, horses, and livestock like cows, goats, sheep, and pigs. It is an effective treatment for a high fever caused by infections, such as Eperythrozoon, toxoplasmosis, circovirus, and infectious pleurisy.
Due to its antispasmodic properties, it can also be used to treat gastrointestinal, biliary, or urinary colic, such as spasmodic pain in the reproductive system. The effectiveness of the drug in these scenarios is attributed to its ability to relax smooth muscles and alleviate the associated pain, thus providing comfort.
Active Ingredient:
Metamizole sodium belongs to the family of medicines called ampyrone sulfonates. It displays strong antipyretic, spasmolytic, and analgesic properties and weak anti-inflammatory action. Metamizole is thought to work by inhibiting central cyclooxygenase-3 and activating the cannabinoid and opioidergic system.
After administration, metamizole is rapidly absorbed and metabolized into various compounds, with its primary active metabolite being 4-methylaminoantipyrine (MAA). This metabolite is known for its potent pain-relieving and fever-reducing properties. The metabolites are predominantly excreted through the kidneys, making renal function an important consideration in its use. The relatively quick onset of action and the duration of the effect make metamizole a practical choice in acute pain and fever management in veterinary settings.

Responsible Use:
