Betol, C6H4·OH·COO (C10H7) = C17H12O3, the salicylic ester of β-naphtol.
Actions and Uses.—Betol is not affected in the stomach, but is split up in its original components when it reaches the intestinal tract by the pancreatic juice and intestinal secretions. It is believed to act as an intestinal antiseptic and, being excreted in the urine, to act in a similar way in the bladder. It has the anti-rheumatic properties of salicylic acid. It is recommended for intestinal fermentations, catarrh of the bladder, particularly in gonorrheal cystitis, for rheumatism, etc. Dosage.—0·3 to 0·5 gramme (4 to 8 grains) in cachets, milk or emulsion.
