Bendazac principally demonstrates an antidenaturant action on proteins. This effect has been shown to inhibit the denaturation of various proteins like ocular lens proteins by heat, ultraviolet radiation, free radicals, and other chemicals. The medication may be administered to patients via a number of different formulations, including orally as the lysine salt, as eye drops, or even topical applications for the skin. Some preliminary studies have suggested that an apparent improvement of the blood-retinal barrier had been observed in diabetic patients using bendazac lysine 500 mg three times a day for three to six months. Moreover, the use of topical bendazac has also been shown to demonstrate anti-inflammatory effects in animal models and clinical studies to effectively treat varied dermatoses, especially those involving a necrotic component. Additionally, bendazac has also demonstrated choleretic and antilipidaemic activities that have resulted in substantial reductions in beta/alpha lipoprotein ratio, and total lipid, total cholesterol, and triglyceride levels in patients with dyslipidaemia using oral bendazac lysine 500 mg three times daily. The medication has also elicited the inhibition of phytohaemagglutinin induced lymphocyte transformation in vitro.

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.
