Alcex Lc

Uses

Calcium is a mineral found in over-the-counter supplements or prescription formulations used for the treatment of specific medical conditions related to calcium deficiency.

Calcium plays a vital role in the anatomy, physiology and biochemistry of organisms and of the cell, particularly in signal transduction pathways. It is vital in cell signaling, muscular contractions, bone health, and signalling cascades.

The supplemental Levocarnitine use is widely established in the management of cardiac ischemia and peripheral arterial disease. It is generally used for cardio protection. It lowers triglyceride levels and increases levels of HDL cholesterol. It is used with benefits in those with primary and secondary carnitine deficiency syndromes. There is also evidence of its use in liver, kidney and immune disorders or in diabetes and Alzheimer's disease. There is little evidence that supplemental Levocarnitine boosts energy, increases athletic performance or inhibits obesity. The indications of Levocarnitine may be summarized as follows:

• Heart Diseases
• Congestive Heart Failure
• Kidney Disease
• Chronic Fatigue Syndrome
• High Cholesterol
• Intermittent Claudication
• Dementia and memory impairment
• Down Syndrome
• Male infertility
• Hyperthyroidism

Alcex Lc is also used to associated treatment for these conditions: Calcium Deficiency, Deficiency, Vitamin D, Osteodystrophy, Osteomalacia, Osteoporosis, Chronic Hypocalcemia, Chronic Hypocalcemia caused by anticonvulsant medications, Care of the Joint, Mineral supplementation, Nutritional supplementationCarnitine Deficiency, Congenital carnitine deficiency, Secondary Carnitine deficiency

How Alcex Lc works

Calcium plays a vital role in the anatomy, physiology and biochemistry of organisms and of the cell, particularly in signal transduction pathways. More than 500 human proteins are known to bind or transport calcium. The skeleton acts as a major mineral storage site for the element and releases Ca2+ ions into the bloodstream under controlled conditions. Circulating calcium is either in the free, ionized form or bound to blood proteins such as serum albumin. Parathyroid hormone (secreted from the parathyroid gland) regulates the resorption of Ca2+ from bone. Calcitonin stimulates incorporation of calcium in bone, although this process is largely independent of calcitonin. Although calcium flow to and from the bone is neutral, about 5 mmol is turned over a day. Bone serves as an important storage point for calcium, as it contains 99% of the total body calcium. Low calcium intake may also be a risk factor in the development of osteoporosis. The best-absorbed form of calcium from a pill is a calcium salt like carbonate or phosphate. Calcium gluconate and calcium lactate are absorbed well by pregnant women. Seniors absorb calcium lactate, gluconate and citrate better unless they take their calcium supplement with a full breakfast. The currently recommended calcium intake is 1,500 milligrams per day for women not taking estrogen and 800 milligrams per day for women on estrogen. There is close to 300 milligrams of calcium in one cup of fluid milk. Calcium carbonate is currently the best and least expensive form of calcium supplement available.

Levocarnitine can be synthesised within the body from the amino acids lysine or methionine. Vitamin C (ascorbic acid) is essential to the synthesis of carnitine. Levocarnitine is a carrier molecule in the transport of long chain fatty acids across the inner mitochondrial membrane. It also exports acyl groups from subcellular organelles and from cells to urine before they accumulate to toxic concentrations. Only the L isomer of carnitine (sometimes called vitamin BT) affects lipid metabolism. Levocarnitine is handled by several proteins in different pathways including carnitine transporters, carnitine translocases, carnitine acetyltransferases and carnitine palmitoyltransferases.

Dosage

Alcex Lc dosage

Tablet-

• Adults: The recommended oral dosage for adults is 990 mg, two or three times a day using the 330 mg tablets, depending on clinical response.
• Infants and children: The recommended oral dosage for infants and children is between 50 and 100 mg/kg/day in divided doses, with a maximum of 3 g/day. Dosage should begin at 50 mg/kg/day. The exact dosage will depend on clinical response.

Monitoring should include periodic blood chemistries, vital signs, plasma carnitine concentrations and overall clinical condition.Syrup-

• Adults: 10 to 30 ml/day. Dosage should start at 10 ml/day in divided doses, and be increased slowly while assessing tolerance and therapeutic response.
• Infants and children: 50 to 100 mg/kg/day which is equivalent to 0.5 ml/kg/day. Dosage should start at 50 mg/kg/day, and be increased slowly to a maximum of 3 g/day (30 ml/day) while assessing tolerance and therapeutic response. Solution may be consumed alone or dissolved in drink or other liquid food. 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.

Side Effects

Generally Levocarnitine is well tolerated. However, few side effects including transient nausea and vomiting, abdominal cramps, and diarrhoea may occur

Toxicity

LD₅₀ > 8g/kg (mouse, oral). Adverse effects include hypertension, fever, tachycardia and seizures.

Precaution

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 (TMAO), since these metabolites are normally excreted in the urine

Interaction

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.

Volume of Distribution

The steady state volume of distribution (Vss) of an intravenously administered dose, above endogenous baseline levels, was calculated to be 29.0 +/- 7.1L. However this value is predicted to be an underestimate of the true Vss.

Elimination Route

Absolute bioavailability is 15% (tablets or solution). Time to maximum plasma concentration was found to be 3.3 hours.

Half Life

17.4 hours (elimination) following a single intravenous dose.

Clearance

Total body clearance was found to be a mean of 4L/h.

Elimination Route

The kidney excretes 250 mmol a day in urine, and resorbs 245 mmol, leading to a net loss in the urine of 5 mmol/d.

Following a single intravenous dose, 73.1 +/- 16% of the dose was excreted in the urine during the 0-24 hour interval. Post administration of oral carnitine supplements, in addition to a high carnitine diet, 58-65% of the administered radioactive dose was recovered from urine and feces in 5-11 days.

Pregnancy & Breastfeeding use

Levocarnitine is categorized by the USFDA as Pregnancy Category B. There are no adequate and well-controlled studies in pregnant women. Supplemental Levocarnitine should be used by pregnant women only if clearly indicated and only under medical supervision. It is not known whether Levocarnitine is excreted in human milk. Supplemental Levocarnitine is not advised for nursing mothers. Those with seizure disorders should only use Levocarnitine under medical advisement and supervision.

Contraindication

There is no known disease or syndrome in which Levocarnitine administration is contraindicated. It is contraindicated in patients with hypersensitivity to any of its components.

Acute Overdose

There have been no reports of toxicity from levocarnitine overdosage. Levocarnitine is easily removed from plasma by dialysis. The intravenous LD50 of levocarnitine in rats is 5.4 g/kg and the oral LD50 of levocarnitine in mice is 19.2 g/kg. Large doses of levocarnitine may cause diarrhea.
