The chemical name of levocarnitine is 3-carboxy-2 R -hydroxy-N,N,N-trimethylpropanaminium, inner salt. Levocarnitine is a white crystalline, hygroscopic powder. It is readily soluble in water, hot buy carnitor levocarnitine liquid, and insoluble in acetone. Its chemical structure is:. The pH is approximately 5. It has been shown to facilitate long-chain fatty acid entry into cellular mitochondria, thereby delivering substrate for oxidation and subsequent energy production.
Fatty acids are utilized as an energy substrate in all tissues except the brain. In skeletal and cardiac muscle, fatty acids are the main substrate for energy production. Secondary carnitine deficiency can be a consequence of inborn errors of metabolism. Conditions for which this effect has been demonstrated are: The subsequent hydrolysis of the acylCoA compound to its free acid results in acidosis which can be life-threatening.
Levocarnitine clears the acylCoA compound by formation of acylcarnitine, which is quickly excreted. In premature infants and newborns, secondary deficiency is defined as plasma levocarnitine concentrations below age-related normal concentrations.
Following a single i. Using plasma concentrations uncorrected for endogenous levocarnitine, the mean distribution half life was 0. Levocarnitine was not bound to plasma protein or albumin when tested at any concentration or with any species including the human. Maximum concentration of [ 3 H-methyl]-L-carnitine in serum occurred from 2. Associated symptoms included hypotonia, muscle weakness and failure to thrive.
In some patients, particularly those presenting with cardiomyopathy, carnitine supplementation rapidly alleviated signs and symptoms. Treatment should include, in addition to carnitine, supportive and other therapy as indicated by the condition of the patient. Gastrointestinal reactions may result from a too rapid consumption buy carnitor levocarnitine liquid carnitine.
They should be consumed slowly and doses should be spaced evenly throughout the day to maximize buy carnitor levocarnitine liquid. The safety and efficacy of oral levocarnitine has not been evaluated in patients with renal insufficiency. Chronic administration of high doses of oral levocarnitine in patients with severely compromised renal function or in ESRD patients on dialysis may result in accumulation of the potentially toxic metabolites, trimethylamine TMA and trimethylamine-N-oxide TMAOsince these metabolites are normally excreted in the urine.
Reports of INR increase with the use of warfarin have been observed. It is recommended that INR levels be monitored in patients on warfarin therapy after the initiation of treatment with levocarnitine or after dose adjustments.
Mutagenicity tests performed in Salmonella typhimurium, Saccharomyces cerevisiae, and Schizosaccharomyces pombe indicate that levocarnitine is not mutagenic. No long-term animal studies have been performed to evaluate the carcinogenic potential of levocarnitine. Reproductive studies have been performed in rats and rabbits at doses up buy carnitor levocarnitine liquid 3.
There are, however, no adequate and well controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Levocarnitine supplementation in nursing mothers has not been specifically studied. Studies in dairy cows indicate that the concentration of levocarnitine in milk is increased following exogenous administration of buy carnitor levocarnitine liquid.
In nursing mothers receiving levocarnitine, any risks to the child of excess carnitine intake need to be weighed against the benefits of levocarnitine supplementation buy carnitor levocarnitine liquid the mother. Consideration may be given to discontinuation of nursing or of levocarnitine treatment.
Various mild gastrointestinal complaints have been reported during the long-term administration of oral L- or D,L-carnitine; these include transient nausea and vomiting, abdominal cramps, and diarrhea. Mild myasthenia has been described only in uremic patients receiving D,L-carnitine. Decreasing the dosage often diminishes or eliminates drug-related patient body odor or gastrointestinal symptoms when present.
Tolerance should be monitored very closely during the first week of administration, and after any dosage increases. Seizures have been reported to occur in patients with or buy carnitor levocarnitine liquid pre-existing seizure activity receiving either oral or intravenous levocarnitine.
There have been no reports of toxicity from levocarnitine overdosage. Levocarnitine buy carnitor levocarnitine liquid easily removed from plasma by dialysis. The intravenous LD 50 of levocarnitine in rats is 5. Large doses of levocarnitine may cause diarrhea. The recommended oral dosage for adults is mg two or three times a day using the mg tablets, depending on clinical response. The exact dosage will depend on clinical response. Monitoring should include periodic blood chemistries, vital signs, plasma carnitine concentrations and overall clinical condition.
Higher doses buy carnitor levocarnitine liquid be administered only with caution and only where clinical and biochemical considerations make it seem likely that higher doses will be of benefit. Monitoring should include periodic blood chemistries, vital signs, plasma carnitine concentrations, and overall clinical buy carnitor levocarnitine liquid.
Doses should be spaced evenly throughout the day every three or four hours preferably during or following meals and should be consumed slowly in order to maximize tolerance.
