In the present study, we evaluated the therapeutic efficacy of acetyl-l-carnitine (ALC) administration on mitochondrial dysfunction following tenth thoracic level contusion spinal cord injury (SCI) in rats. Initial results from experiments in vitro with naïve mitochondria showed that, in the absence of pyruvate, ALC can be used as an alternative substrate for mitochondrial respiration. Addition...

The effect of short- and long-term feeding with L-carnitine, L-acetyl carnitine and L-propionyl carnitine on the production of eicosanoids from in vitro stimulated carrageenan-induced rat peritoneal macrophages was investigated. Both young (4 weeks) and old (18 months) rats were used. A lower number of cells was isolated from the peritonea of treated than control young rats after 4 d feeding, b...

Acetyl-L-carnitine (ALC) has gained clinical interest for its analgesic effect in different forms of neuropathies associated with chronic pain, such as diabetic and HIV-related peripheral neuropathies. The antinociceptive effect of ALC has been confirmed in several experimental models of neuropathic pain, including streptozotocin- and chemotherapy-induced neuropathy, and the sciatic nerve chron...

AIM The study aimed to evaluate the efficacy of acetyl-l-carnitine (ALC), at different doses, in relapse prevention and craving in anhedonic detoxified alcohol-dependent subjects. METHOD Randomized, double-blind, placebo-controlled, pilot study in 64 alcohol-dependent anhedonic patients: 23 received ALC at a dose of 3 g/day, 21 received ALC at a dosage of 1 g/day and 20 were given placebo. In...

The abnormalities underlying diabetic neuropathy appear to be multiple and involve metabolic neuronal and vasomediated defects. The accumulation of long-chain fatty acids and impaired beta-oxidation due to deficiencies in carnitine and/or its esterified derivatives, such as acetyl-L-carnitine, may have deleterious effects. In the present study, we examined, in the diabetic bio-breeding Worceste...

Acetyl-L-carnitine (ALC) is a naturally occurring substance that, when administered at supra-physiological concentration, is neuroprotective. It is involved in membrane stabilization and in enhancement of mitochondrial functions. It is a molecule of considerable interest for its clinical application in various neural disorders, including Alzheimer's disease and painful neuropathies. ALC is know...
