Calcium is used to prevent or treat negative calcium balance. It also helps facilitate nerve and muscle performance as well as normal cardiac function. Bone mineral component; cofoactor in enzymatic reactions, essential for neurotransmission, muscle contraction, and many signal transduction pathways.

Mecobalamin is the neurologically active form of vitamin B12 and occurs as a water-soluble vitamin in the body. It is a cofactor in the enzyme methionine synthase, which functions to transfer methyl groups for the regeneration of methionine from homocysteine. In anaemia, it increases erythrocyte production by promoting nucleic acid synthesis in the bone marrow and by promoting maturation and division of erythrocytes.

Selenium is a trace metal in the human body particularly important as a component of glutathione peroxidase, an important enzyme in the prevention of cellular damage by free radicals and reactive oxygen species

Selenium is incorporated into many different selenoproteins which serve various functions throughout the body .

Silymarin possess hepatoprotective and antioxidant activity. The hepatoprotective effect is due to stimulation of synthesis of structural and functional proteins and phospholipids, as well as acceleration of the regeneration of hepatocytes.

Antioxidant effect is determined by interaction of bioflavones with free radicals in the liver and its detoxication. In such manner the process of peroxidation of the lipids is interupted and further liver destruction is prevented.

Clinically, these effects are manifested by improvement of the signs and symptoms and normalization of the liver variables (serum level of transaminases, gamma-globulins, and bilirubin).

Selenium is an ingredient found in a variety of supplements and vitamins.

For the supplementation of total parenteral nutrition to prevent hyposelenemia .

For the treatment of jaundice, chronic inflammatory liver conditions, i.e. hepatitis, alcoholic liver damage and hepatic cirrhosis. It has anti-oxidant property.

Silimac is also used to associated treatment for these conditions: Vitamin B12 Deficiency, Nutritional supplementationNutritional supplementation

How Silimac works

Selenium is first metabolized to selenophosphate and selenocysteine. Selenium incorporation is genetically encoded through the RNA sequence UGA . This sequence is recognized by RNA ste loop structures called selenocysteine inserting sequences (SECIS). These structures require the binding of SECIS binding proteins (SBP-2) to recognize selenocystiene. The specialized tRNA is first bound to a serine residue which is then enzymatically processed to a selylcysteyl-tRNA by selenocystiene sythase using selenophosphate as a selenium donor. Other unidentified proteins are required as part of the binding of this tRNA to the ribosome. Selenoproteins appear to be necessary for life as mice with the specialized tRNA gene knocked out exhibited early embryonic lethality .

The most important selenoproteins seem to be the glutathione peroxidases and thioredoxin reductases which are part of the body's defenses againts reactive oxygen species (ROS) . The importance of selenium in these anti-oxidant proteins has been implicated in the reduction of atherosclerosis by preventing the oxidation of low density lipoprotein . Selenium supplementation is also being investigated in the prevention of cancer and has been suggested to be beneficial to immune function .

Dosage

Silimac dosage

Slow intravenous or deep intramuscularas required or as directed by physician.

Tablet: The usual adult dosage is one 500 mcg tablet three times daily. The dosage should be adjusted according to the age of patient and the severity of symptoms.

Injection:

Peripheral neuropathies: The usual adult dosage is one ampoule equivalent to 500 mcg of Mecobalamin, administered intramuscularly or intravenously three times a week.The dosage should be adjusted according to the age of patient and the severity of symptoms.
Megaloblastic anemia: The usual adult dosage is one ampoule equivalent to 500 mcg of Mecobalamin, administered intramuscularly or intravenously three times a week. After about two months of administration, dosage should be changed to one ampoule equivalent to 500 mcg of Mecobalamin every one to three months as maintenance therapy

70 mg or 140 mg or 500 mg capsule should be taken 3 times daily as per the instruction of a physician. The medication should be continued until the relief of the symptoms according to the advice of a physician.

Side Effects

Mild gastrointestinal disturbances, bradicardia, arrythmia and irritation after IV injection

Generally Mecobalamin is well tolerated. However, a few side effects like GI discomfort (including anorexia, nausea or diarrhea) & rash may be seen after administration of Mecobalamin.

A mild laxative effect has occasionally been observed.

Toxicity

Oral LD50 of 6700mg/kg in rats . Selenium exposure is teratogenic and can result in fetal death as tested in mice. Chronic toxicity is characterized by hair loss, white horizontal streaking on fingernails, paronchyia, fatigue, irritability, hyperreflexia, nausea, vomiting, garlic odor on breath, and metallic taste . Serum selenium correlates weakly with symtoms. Blood chemistry as well as liver and kidney function are normally unnaffected. Acute toxicity presents as stupor, respiratory depression, and hypotension. ST elevations and t-wave changes characteristic of myocardial infarction may be observed.

Precaution

Renal impairment, sarcoidosis, concurrent administration of thiazide diuretics may increase the risk of hypercalcaemia.

The medicine should not be used for months if there is no response at all after its use for a certain period of time.

Interaction

There are no known drug interactions and none well documented.

Decreased GI tract absorption with neomycin, aminosalicylic acid, H2-blockers and colchicine. Reduced serum concentrations with oral contraceptives. Reduced effects in anaemia with parenteral chloramphenicol.

Elimination Route

Oral bioavailability of 90% when given as L-selenomethionine . Tmax of 9.17h.

Half Life

Half life was observed to increase with chronic dosing time . For day 1-2 half life was 1.7 days. For day 2-3 half life was 3 days. For day 3-14 half life was 11.1 days.

Elimination Route

Mainly excreted in urine as 1beta-methylseleno-N-acetyl-d-galactosamine and trimethylselenonium . The amount excreted as 1beta-methylseleno-N-acetyl-d-galactosamine plateaus at doses around 2microg after which the amount excreted as trimethylselenonium increases. Some selenium is also excreted in feces when given orally .

Pregnancy & Breastfeeding use

Pregnancy Category-C. Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks
