RT Journal Article SR Electronic T1 Potassium para-aminobenzoate (potaba) in scleroderma JF Drug and Therapeutics Bulletin JO Drug Ther Bull FD BMJ Publishing Group Ltd SP 47 OP 48 DO 10.1136/dtb.6.12.47 VO 6 IS 12 YR 1968 UL http://dtb.bmj.com/content/6/12/47.abstract AB In the past fifteen years there have been numerous reports on the treatment of scleroderma and related conditions with potassium para-aminobenzoate (Potaba - Glenwood Laboratories). The use of this ‘antifibrotic’ treatment is empirical. p-Aminobenzoic acid (PABA) is not known to affect fibrosis or fibrous tissue experimentally. Many bacteria require it for the synthesis of folic acid, and sulphonamides antagonise their utilisation of it.
