alpha-tocopherol Uses, Dosage, Side Effects, Food Interaction and all others data.
alpha-tocopherol Capsule is a alpha-tocopherol preparation. alpha-tocopherol acts as an antioxidant in the body. alpha-tocopherol protects polyunsaturated fatty acids (which are components of cellular membrane) and other oxygen-sensitive substances such as vitamin A & vitamin C from oxidation. alpha-tocopherol reacts with free radicals, which is the cause of oxidative damage to cell membranes, without the formation of another free radical in the process. The main pharmacological action of vitamin E in humans is its antioxidant effect.
In premature neonates irritability, edema, thrombosis and hemolytic anemia may be caused due to vitamin E deficiency. Creatinuria, ceroid deposition, muscle weakness, decreased erythrocyte survival or increased in vitro hemolysis by oxidizing agents have been identified in adults and children with low serum tocopherol concentrations.
alpha-tocopherol is a collective term used to describe 8 separate fat soluble antioxidants, most commonly alpha-tocopherol. alpha-tocopherol acts to protect cells against the effects of free radicals, which are potentially damaging by-products of the body's metabolism. alpha-tocopherol deficiency is seen in persons with abetalipoproteinemia, premature, very low birth weight infants (birth weights less than 1500 grams, or 3½ pounds), cystic fibrosis, and cholestasis and severe liver disease. Preliminary research suggests vitamin E may help prevent or delay coronary heart disease and protect against the damaging effects of free radicals, which may contribute to the development of chronic diseases such as cancer. It also protects other fat-soluble vitamins (A and B group vitamins) from destruction by oxygen. Low levels of vitamin E have been linked to increased incidence of breast and colon cancer.

alpha-tocopherol is also used to associated treatment for these conditions: Vitamin Deficiency, Long-chain omega-3 fatty acid supplementation, Dietary supplementation
How alpha-tocopherol works
The mechanism of action for most of vitamin E's effects are still unknown. alpha-tocopherol 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. alpha-tocopherol 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
alpha-tocopherol dosage
Betterment of Cardiovascular health: 400 mg - 800 mg / day
Deficiency syndrome in adults: 200 mg - 400 mg / day
Deficiency syndrome in children: 200 mg / day
Thalassemia: 800 mg / day
Sickle-cell anemia: 400 mg / day
Betterment of Skin & Hair: 200 mg - 400 mg / day (Topical use is also established for beautification)
Chronic cold in adults: 200 mg / day
Side Effects
Overdoses (>1g) have been associated with minor side effects, including hypertension, fatigue, diarrhea and myopathy
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
alpha-tocopherol may enhance the anticoagulant activity of anticoagulant drugs. Caution is advised in premature infants with high dose alpha-tocopherol supplementation, because of reported risk of necrotizing enterocilitis.
Interaction
alpha-tocopherol may impair the absorption of Vitamin A. Vitamin K functions impairement happens at the level of prothrombin formation and potentiates the effect of Warfarin.
Food Interaction
- Take with or without food. High-fat foods may increase absorption of alpha-tocopherol.
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 alpha-tocopherol 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
Use in pregnancy: alpha-tocopherol may be used in pregnancy in the normally recommended dose but the safety of high dose therapy has not been established.
Use in lactation: There appears to be no contraindication to breast feeding by mothers taking the normally recommended dose.
Contraindication
No known contraindications found.
Special Warning
Use in Children: alpha-tocopherol 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
Store at a cool and dry place, Protect from light and moisture.
