Menadiol is one of the forms of vitamin K4. Chemically, it is closely related to menadione. Oral menadiol appears to be an effectiv ealternative to intravenous phytomenadione in the correction of coagulopathies associated with obstructiveliver disease. This simplifies the care of patients with deranged clotting times requiring cholangeopancrea-tography, particularly those to be managed as out-patients. Menadiol should receive clinical testing as a chemosensitizing agent in human lymphatic neoplasms (HLN). This effect occurred at a concentration (2.0 micrograms/ml; 4.7 microM) of menadiol which is probably clinically achievable and which did not deplete intracellular glutathione.

Acetomenaphthane, A vitamin K analogue used to treat and prevent hypoprothrombinemia caused by vitamin K deficiency. Also called menadiol diacetate. Hypoprothrombinemia is a blood disorder in which a deficiency of prothrombin results in impaired blood clotting, leading to an increased physiological risk for bleeding, especially in the gastrointestinal system, cranial vault, and superficial integumentary system.

Menadiol sodium sulfate is a metabolite of one of the forms of vitamin K4, which was found in a biofluid of rodents.
