What is Aminobenzoate Potassium

Aminobenzoate potassium is an oral antifibrotic agent. It is the potassium salt of para-aminobenzoic acid (PABA) and is used to treat serious, often chronic diseases involving fibrosis and nonsuppurative inflammation.

The drug acts gradually, and length of therapy varies with disease state and extent of involvement. Therapy requires the maintenance of adequate dosage over a sufficient length of time, which is usually a minimum of 2 to 3 months.

This drug has been available since before 1938, prior to when Congress passed the 1962 amended Federal Food, Drug, and Cosmetic Act, requiring that the FDA establish both safety and efficacy for all subsequently approved drugs.
