Betol, C_{6}H_{4}·OH·COO (C_{10}H_{7}) = C_{17}H_{12}O_{3}, 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. Manufactured by the Heyden Chemical Works, New York.
