Bendazac seems to elicit an anticataract action by inhibiting the denaturation of ocular lens proteins, although the precise mechanisms by which this action occurs has not yet been formally elucidated - despite there being many proposed mechanisms . In particular, the denaturation of lens proteins may in part be prevented by inhibiting the binding of certain chemicals like cyanates or sugars and 5-hydroxybendazac - the major metabolite of bendazac - has been shown to be capable of inhibiting the glycosylation of lens proteins by sugars like galactose or glucose-6-phosphate in a dose-dependent manner . Moreover, the apparent ability for administered bendazac to elicit free radical scavenger activities due to interactions with protein molecules suggests that the medication may also be able to prevent the oxidation of lens proteins by free radicals in the development of cataracts . Furthermore, bendazac may also be capable of reducing the sulfhydryl group oxidation of lens proteins by the saliva, serum, or urine from patients with cataracts following single dose administration and reduce biological liquid oxidant activity (BLOA) in doing so . Otherwise, it is believed that bendazac also possesses non-steroidal anti-inflammatory actions, as well as analgesic, antipyretic, and platelet-inhibitory effects These effects may be accounted for in part by the substance's capability to inhibit prostaglandin synthesis by inhibiting cyclooxygenase activity in converting arachidonic acid to cyclic endoperoxides - the precursors of prostaglandins .
Prior to the withdrawal of bendazac from various international regions of use due to concerns for hepatotoxicity the chemical had demonstrated potential usefulness predominantly as the prescription medication bendazac lysine for the indication of managing the level of vision in patients with mild to moderate cataracts to facilitate delaying the need for surgical intervention . Elsewhere bendazac may still be available in a limited capacity as a non-prescription topical cream product for treating conditions like local pain, inflammation, dermatitis, eczema, pruritis, hives, insect bites, burns, erythema, and others - although such products may also be facing general discontinuation .
