"The mechanisms of action of acetylcarnitine have not been fully elucidated, but it seems that the main role of acetylcarnitine is to donate an acetyl group during fatty acid metabolism to help transport fatty acids, such as acetyl CoA, into the mitochondrial matrix where fatty acid metabolism occurs. Additionally several studies have found that separate from its metabolic role, acetylcarnitine has neuromodulatory, neurotrophic, and neuroprotective effects that most likely are involved in its positive effects in neurological diseases. In its role in treating male infertility, acetylcarnitine increases the active movement of sperm cells. One study has also mentioned a role for acetylcarnitine as an antioxidant. The study found that through the receptor, tyrosine kinase A, acetylcarnitine was able to decrease the production of free radicals, peroxidation of lipids, and oxidation of proteins as well as decrease glutathione levels and increase thioredoxin."@en . . . . . . "Humans and other mammals"@en . . . "Acetylcarnitine is not approved for any indication in the United states and Canada, but it is approved and indicated in Italy for cerebrovascular disorders, mental function disorders, peripheral nerve disorders, diabetic neuropathy, and nutritional supplementation; Portugal for mental function disorders; Argentina for cerebral vasculopathy, nutritional supplementation, and peripheral neuropathy; Chile for dementia; Philippines for cerebrovascular disorders and mental function disorders; Australia for nutritional supplementation; and India for nutritional supplementation to increase sperm count. Acetylcarnitine also has several potential therapeutic indications for which it is still being investigated: in Norway, acetylcarnitine is in a phase IV trial for prophylactic treatment of migraines; in Italy acetylcarnitine is in a phase II trial for use in patients with type 2 Diabetes Mellitus, a phase III trial for alleviating fatigue in patients with chronic hepatitis C, and for use in patients with Minimal Hepatic Encephalopathy; in the United States acetylcarnitine is in a phase II trial for the neurodegenerative disorder Progressive Supranuclear Palsy, a phase II and III trial for reducing peripheral neuropathy in cancer patients as an adjunct to chemotherapy, a phase I and II trial for treating patients in septic shock, a phase II trial for bipolar depression, a phase II trial to reduce oxidative stress in patients with Sickle Cell disease, a phase I and II trial for chronic fatigue syndrome, and a study for preventing nerve damage in HIV patients; in China acetylcarnitine is in a phase III trial for reducing peripheral neuropathy in cancer patients as an adjunct to chemotherapy; in the United Kingdom acetylcarnitine is being investigated for preventing nerve damage in HIV patients; and in Israel acetylcarnitine is being studied for the treatment of male infertility.
