Vitamin B6

Dr Daniel J Bell and Dr Craig Hacking et al.

Vitamin B6 is a group of water-soluble vitamins, part of the vitamin B complex, and that are derivatives of pyridine, namely pyridoxine, pyridoxal and pyridoxamine. All three form part of the coenzyme pyridoxal 5'-phosphate (PLP) which is involved in many cellular reactions including the synthesis of several amino acids and the metabolism of glucose and lipids.

The antitubercular drug isoniazid is an inactive derivative of pyridoxal phosphate, hence vitamin B6 needs to be co-administered in patients on isoniazid.
