Excipient (pharmacologically inactive substance)
What is it?
As an inactive ingredient, tromethamine (C4H11NO3) is used in the synthesis of surface-active agents and pharmaceuticals; as an emulsifying agent for cosmetic creams and lotions, mineral oil and paraffin wax emulsions, as a biological buffer, and used as an alkalizer. Tromethamine as a pharmaceutical agent is used to treat metabolic acidosis (an electrolyte imbalance). Metabolic acidosis can have many causes. It often occurs after heart bypass surgery or cardiac arrest.
