Laminil is the first injectable drug treatment for acute and active chronic laminitis that inhibits the inflammatory response and the laminitis cascade. Laminil can treat both acute laminitis and active chronic laminitis. The drug is a mast cell stabilizer that inhibits inflammatory mediators and other chemicals from being released from the mast cell in excess. When the inflammatory mediators are not released in excess, then the laminitis cascade is broken/halted, and the horse is able to heal and recover.
