Abstract: It was discovered that bendazac, or (1-phenylmethyl-1H-indazol -3-yl)oxy acetic acid, when administered in a form suitable to obtain therapeutic tissue concentrations, determine an improvement in retinitis pigmentosa. The lysine salt of bendazac is well adapted for this use owing to its good oral absorption.

Abstract: It was discovered that bendazac, or [(1-benzyl-1H-indazol-3-yl)oxy] acetic acid, when administered in a form suitable to obtain therapeutic tissue concentrations, determines a regression of cataract. It was demonstrated in particular, that the lysine salt of bendazac is well adapted for this use since it produces adequate tissue concentrations following both oral administration and topical application on the eye. The chemical and physical characteristics of this bendazac salt are described here together with the preparation techniques.

Abstract: A new salt of [(1-benzyl-1H-indazol-3-yl)oxy] acetic acid (or bendazac) with L. lysine.Following oral administrations of this compound in man, the concentrations of bendazac found in the blood are higher than those obtained after administration of bendazac as such.This discovery extends the therapeutic use of bendazac. In fact, whereas up to now bendazac could only be used topically, the L. lysine salt of bendazac makes it possible to perform therapeutic treatments with the oral route of administration as an agent with a normalizing effect on blood lipids.
