Lumitene Pharmacokinetics

Absorption

Bioavailability

Absorption depends on the presence of bile and absorbable fat in the intestinal tract.a e f

Supplemental forms of beta carotene have markedly greater bioavailability than dietary beta carotene.e

Only 20–30% of supplemental beta carotene is absorbed unchanged.a

Onset

Photosensitivity protecting action occurs after at least 2–4 weeks and usually coincides with the development of carotenodermia.a

Duration

Decreased tolerance to light usually is evident within 1–2 weeks after discontinuing beta carotene therapy.a

Plasma Concentrations

Blood carotene concentrations reach a maximum and carotenodermia usually develops about 4–6 weeks after beginning beta carotene therapy.a

Special Populations

Absorption is greatly decreased in patients with steatorrhea and chronic diarrhea.a

Distribution

Extent

Widely distributed in the body.a e Accumulates in the skin and in various tissues, particularly depot fat.a

Not known if distributed into human milk.a f

Elimination

Metabolism

Metabolized, principally in the small intestine, to vitamin A;a f smaller amounts metabolized in the liver.f

Elimination Route

Excreted in fecesf and urine as metabolites.a

Stability

Storage

Oral

Capsules

Tight, light-resistant containers.a

Advice to Patients

  • Inform patients that carotenodermia may develop after 2–6 weeks of therapy; usually first noticed as yellowness of the palms of the hands or soles of the feet and to a lesser extent of the face.a f

  • Advise patients against taking supplementary vitamin A because beta carotene will fulfill normal vitamin A requirements.a f

  • Advise EPP patients that the protective effect of beta carotene is not total and that they may still develop considerable burning and edema after sufficient exposure to sunlight.a f Explain that each patient must establish his own time limit of exposure to sunlight.a f

  • Inform EPP patients not to increase time of exposure to the sun until carotenodermia is evident.a f

  • Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.f

  • Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs, as well as any concomitant illnesses.f

  • Importance of informing patients of other important precautionary information.f (See Cautions.)

Uses For Lumitene

Vitamins are compounds that you must have for growth and health. They are needed in small amounts only and are usually available in the foods that you eat. Beta-carotene is converted in the body to vitamin A, which is necessary for healthy eyes and skin.

A lack of vitamin A may cause a rare condition called night blindness (problems seeing in the dark). It may also cause dry eyes, eye infections, skin problems, and slowed growth. Your health care professional may treat these problems by prescribing either beta-carotene, which your body can change into vitamin A, or vitamin A for you.

Some conditions may increase your need for vitamin A. These include:

  • Cystic fibrosis
  • Diarrhea, continuing
  • Illness, long-term
  • Injury, serious
  • Liver disease
  • Malabsorption problems
  • Pancreas disease

Increased need for vitamin A should be determined by your health care professional.

Claims that beta-carotene is effective as a sunscreen have not been proven. Although beta-carotene supplements are being studied for their ability to reduce the risk of certain types of cancer and possibly heart disease, there is not enough information to show that this is effective.

Beta-carotene may be used to treat other conditions as determined by your doctor.

Beta-carotene is available without a prescription.

For use as a dietary supplement:

  • For oral dosage forms (capsules or chewable tablets):
    • Adults and teenagers: 6 to 15 milligrams (mg) of beta-carotene (the equivalent of 10,000 to 25,000 Units of vitamin A activity) per day.
    • Children: 3 to 6 mg of beta-carotene (the equivalent of 5,000 to 10,000 Units of vitamin A activity) per day.

For other uses:

  • For oral dosage forms (capsules or tablets):
    • To treat or prevent a reaction to sun in patients with erythropoietic protoporphyria:
      • Adults and teenagers—30 to 300 milligrams (mg) of beta-carotene (the equivalent of 50,000 to 500,000 Units of vitamin A activity) a day.
      • Children—30 to 150 mg of beta-carotene (the equivalent of 50,000 to 250,000 Units of vitamin A activity) a day.
    • To treat or prevent a reaction to sun in patients with polymorphous light eruption:
      • Adults and teenagers—75 to 180 mg of beta-carotene (the equivalent of 125,000 to 300,000 Units of vitamin A activity) a day.
      • Children—30 to 150 mg of beta-carotene (the equivalent of 50,000 to 250,000 Units of vitamin A activity) a day.

If you have high blood levels of vitamin A, your body will convert less beta-carotene to vitamin A.

Precautions While Using Lumitene

Use of beta-carotene has been associated with an increased risk of lung cancer in people who smoke or who have been exposed to asbestos. One study of 29,000 male smokers found an 18% increase in lung cancer in the group receiving 20 mg of beta-carotene a day for 5 to 8 years. Another study of 18,000 people found 28% more lung cancers in people with a history of smoking and/or asbestos exposure. These people took 30 mg of beta-carotene in addition to 25,000 Units of retinol (a form of vitamin A) a day for 4 years. However, one study of 22,000 male physicians, some of them smokers or former smokers, found no increase in lung cancer. These people took 50 mg of beta-carotene every other day for 12 years. If you smoke or have a history of smoking or asbestos exposure, you should not take large amounts of beta-carotene supplements for long periods of time. However, foods that are rich in beta-carotene are considered safe and appear to lower the risk of some types of cancer and possibly heart disease.

Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:
