Description: Benfotiamine, or S-benzoylthiamine O-monophosphate, is a synthetic S-acyl derivative of thiamine (vitamin B1). It is prescribed there for treating sciatica and other painful nerve conditions. It is marketed as a medicine and/or dietary supplement, depending on the respective Regulatory Authority. Benfotiamine upregulates antioxidative system in activated BV-2 microglia cells. Benfotiamine enhances antioxidant defenses and protects against cisplatin-induced DNA damage in nephrotoxic rats.

Additional Information

Benfotiamine is primarily marketed as an antioxidant dietary supplement. In a clinical study with six patients, benfotiamine lowered AGE by 40%. Benfotiamine may be useful for the treatment of diabetic retinopathy, neuropathy, and nephropathy however "Most of the effects attributed to benfotiamine are extrapolated from in vitro and animal studies. Unfortunately apparent evidences from human studies are scarce and especially endpoint studies are missing. Therefore additional clinical studies are mandatory to explore the therapeutic potential of benfotiamine in both diabetic and non-diabetic pathological conditions". It is thought that treatment with benfotiamine leads to increased intracellular thiamine diphosphate levels, a cofactor of transketolase. This enzyme directs advanced glycation and lipoxidation end products (AGE's, ALE's) substrates to the pentose phosphate pathway, thus reducing tissue AGEs.
