4 Drug and Medication Information
4.1 Therapeutic Uses

/CLINICAL TRIALS/ ClinicalTrials.gov is a registry and results database of publicly and privately supported clinical studies of human participants conducted around the world. The Web site is maintained by the National Library of Medicine (NLM) and the National Institutes of Health (NIH). Each ClinicalTrials.gov record presents summary information about a study protocol and includes the following: Disease or condition; Intervention (for example, the medical product, behavior, or procedure being studied); Title, description, and design of the study; Requirements for participation (eligibility criteria); Locations where the study is being conducted; Contact information for the study locations; and Links to relevant information on other health Web sites, such as NLM's MedlinePlus for patient health information and PubMed for citations and abstracts for scholarly articles in the field of medicine. Lactic acid is included in the database.

NIH/NLM; ClinicalTrials.Gov. Available from, as of March 17, 2016: https://clinicaltrials.gov/ct2/results?term=lactic+acid&Search=Search


(VET): Has been used as a caustic, and in dilute solutions to irrigate tissues; as an intestinal antiseptic and antiferment.

5.3 Absorption, Distribution and Excretion

L-lactic acid occurs in small quantities in the blood and muscle fluid of humans and animals; the concentration of lactic acid in these fluids increases after vigorous activity. L-lactic acid is also present in the liver, kidneys, thymus gland, human amniotic fluid, and other organs and body fluids.

Cosmetic Ingredient Review Expert Panel; International Journal of Toxicology, 17 (Suppl.1): 1-203 (1998)


A primed infusion study was performed /in humans/ using radioactive L-lactic acid. The virtual volume of distribution of lactate was 49.4% of body weight. The lactate pool size and turnover time were estimated as 0.029 g/kg and 18.4 min, respectively.

Cosmetic Ingredient Review Expert Panel; International Journal of Toxicology, 17 (Suppl.1): 1-203 (1998)


In the body, lactate is distributed equivalently to, or slightly less than, total body water. It diffuses readily across cell membranes, primarily by passive transport; under certain conditions, the distribution could be uneven or the lactate pool could consist of several smaller pools with differing rate constants.

Cosmetic Ingredient Review Expert Panel; International Journal of Toxicology, 17 (Suppl.1): 1-203 (1998)


The percutaneous absorption of topically applied 5% [14C]-lactic acid in an oil-in-water cream was measured using rats. After 3 days, 50% of the applied lactic acid had penetrated the skin.

5.4 Metabolism/Metabolites

... Propylene glycol ... is oxidized to lactic acid or pyruvic acid by two pathways. These two metabolites are then used by the body as sources of energy either by oxidation through the tricarboxylic acid cycle or by generation of glycogen through the glycolytic pathway.

Bingham, E.; Cohrssen, B.; Powell, C.H.; Patty's Toxicology Volumes 1-9 5th ed. John Wiley & Sons. New York, N.Y. (2001)., p. V7 31


Lactic acid diffuses through muscle tissue and is transported to the liver in the bloodstream. In the liver, it is converted to glucose by gluconeogenesis. Lactic acid can also be further catabolized in the lactic acid cycle (also known as the Cori cycle).

Joint FAO/WHO Expert Committee on Food Additives; WHO Food Additives Ser 48: Lactic acid (2002). Available from, as of April 19, 2006: https://www.inchem.org/documents/jecfa/jecmono/v48je16.htm


L-lactic acid is a normal metabolic intermediate produced by most mammalian cells and other organisms, such as bacteria; it is metabolized in preference to D-lactic acid in man, dogs, and rats. Lactic acid is converted to pyruvic acid by lactic acid dehydrogenase.

Cosmetic Ingredient Review Expert Panel; International Journal of Toxicology, 17 (Suppl.1): 1-203 (1998)


In animals, lactate that is generated by anaerobic metabolism can be transported to other more aerobic tissues, such as the liver, where it can be reconverted to pyruvate. The pyruvate can then be further metabolized, reconverted to carbohydrate material as free glucose, or stored as glycogen.

Cosmetic Ingredient Review Expert Panel; International Journal of Toxicology, 17 (Suppl.1): 1-203 (1998)


For more Metabolism/Metabolites (Complete) data for LACTIC ACID (8 total), please visit the HSDB record page.


5.5 Mechanism of Action

Lactate ions are metabolized ultimately to carbon dioxide and water, which requires the consumption of hydrogen cations.
