Active Plus 6 mg+200 mg+50 mg Tablet

Uses

Antioxidant vitamins are used in a wide range of conditions where free radical damage is playing a role. Antioxidant vitamin combination is used in the prevention of coronary heart diseases, certain types of cancer, aging as well as free radical damage caused by excessive exercise, illness, certain medications, air pollution, smoke, radiation and pesticides. The main role of the antioxidant vitamins is as follows:

β carotene prevents free radical formation by quenching singlet oxygen, a highly reactive form of oxygen. Vitamin C is another free radical scavenger which deactivates free radicals. It works specially in the plasma, lung fluid, aqueous humour and interstitial fluid. It can increase white blood cell activity; play important roles in the biochemistry of antibodies, prostaglandin E 1 , B and T lymphocytes, and interferon. Vitamin E also scavenges free radicals in the blood along with β carotene and vitamin C. Moreover, vitamin E is essential to protect against some of the ill effects of smog and smoke. In relation to other nutrients vitamin E protects vitamin A from being destroyed in the body.

Active Plus 6 mg+200 mg+50 mg Tablet is also used to associated treatment for these conditions: Vitamin Deficiency, Long-chain omega-3 fatty acid supplementation, Dietary supplementation

How Active Plus 6 mg+200 mg+50 mg Tablet works

The mechanism of action for most of vitamin E's effects are still unknown. Vitamin E is an antioxidant, preventing free radical reactions with cell membranes. Though in some cases vitamin E has been shown to have pro-oxidant activity.

One mechanism of vitamin E's antioxidant effect is in the termination of lipid peroxidation. Vitamin E reacts with unstable lipid radicals, producing stable lipids and a relatively stable vitamin E radical. The vitamin E radical is then reduced back to stable vitamin E by reaction with ascorbate or glutathione.

Dosage

Active Plus 6 mg+200 mg+50 mg Tablet dosage

This tablet is administered orally. The adult dose of this combination of antioxidant vitamin tablet is 1 tablet daily or as prescribed by the physician.

Side Effects

β carotene is comparatively safe even at high and prolonged exposure. Individuals who routinely ingest large amounts of carotenoids can develop hypercarotenosis, which is characterised by a yellowish colouration of the skin and a very high concentration of carotenoids in the plasma. This benign condition, although resembling jaundice, gradually disappears upon correcting the excessive intake of carotenoids.

Vitamin C is generally a safe drug for human use in normal doses. Larger doses may lead to gastrointestinal tract upset and renal stone formation.

Vitamin E is considered safe even in large doses. Doses over 800 mg may cause diarrhoea, abdominal pain or cramps, fatigue and reduced resistance to bacterial infection and transiently raised blood pressure.

Toxicity

There is no data available for effects in pregnancy, breast feeding, hepatic impairment, or renal impairment. However, it appears that the process of vitamin E elimination is strict and self regulating enough that vitamin E toxicity is exceedingly rare. Studies showing adverse effects from excess vitamin E generally involve people consuming more than 1000mg/day for weeks to months.

Precaution

There are some evidences that β carotene may cause harm to heavy smokers and alcoholics. Therefore, caution should be exercised in these cases. Vitamin C should be given with caution to patients with hyperoxaluria. Vitamin E should be used with caution in patients taking anticoagulant drugs, because vitamin E may enhance the anticoagulant activity of these drugs.

Interaction

Cholestyramine, Colestipol, Neomycin cause decreased absorption of β carotene. Circulating vitamin C levels have been shown to be reduced during prolonged administration of oral contraceptives containing Oestrogen, Tetracycline and Aspirin. The decrease in vitamin C level may be due to drug induced impaired absorption or increased utilization of the vitamin for drug metabolism. Vitamin E may enhance the anticoagulant activity of anticoagulant drugs. High doses of vitamin E can impair intestinal absorption of vitamins A and K.

Volume of Distribution

0.41L/kg in premature neonates given a 20mg/kg intramuscular injection.

Elimination Route

10-33% of deuterium labelled vitamin E is absorbed in the small intestine. Absorption of Vitamin E is dependant upon absorption of the fat in which it is dissolved. For patients with poor fat absorption, a water soluble form of vitamin E may need to be substituted such as tocopheryl polyethylene glycol-1000 succinate.

In other studies the oral bioavailability of alpha-tocopherol was 36%, gamma-tocotrienol was 9%. The time to maximum concentration was 9.7 hours for alpha-tocopherol and 2.4 hours for gamma-tocotrienol.

Half Life

44 hours in premature neonates given a 20mg/kg intramuscular injection. 12 minutes in intravenous injection of intestinal lymph.

Clearance

6.5mL/hr/kg in premature neonates given a 20mg/kg intramuscular injection.

Elimination Route

Alpha tocopherol is excreted in urine as well as bile in the feces mainly as a carboxyethyl-hydrochroman (CEHC) metabolite, but it can be excreted in it's natural form .

Pregnancy & Breastfeeding use

β carotene, vitamin C and vitamin E have no teratogenic effects in humans. However, like any other drugs caution should be taken in prescribing to pregnant women.

Contraindication

Carocet is contraindicated in patients with hypersensitivity to any of its components.

Special Warning

Use in Children: Vitamin E is safe for children

Acute Overdose

Large doses of vitamin E (more than 1 gm/day) have been reported to increase bleeding tendency in vitamin K deficient patients such as those taking oral anticoagulants.

Storage Condition

Should be stored in a dry place below 30˚C.
