Chromium picolinate has a chemical formula CrPic3 and reddish-pink color. It is a coordination complex consisting of chromium(III) and picolinic acid. Chromium picolinate is used as a nutritional supplement for optimal insulin function in patients with Type 2 diabetes or promotion of weight loss. Chromium ions are shown to regulate insulin by promoting glucose utilization and increasing the sensitivity of the insulin receptor .

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 .

How Surbex Xt 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

Surbex Xt dosage

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

Side Effects

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.

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

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

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 .
