How does this medicine work?

• Beta-carotene, retinol, and retinal have effective and reliable vitamin A activity.
• Vitamin A prevents retardation of growth and preserves the epithelial cells' integrity.
• Normal adult liver storage is sufficient to satisfy two years' requirements of vitamin A.
• Vitamin A is readily absorbed from the gastrointestinal tract, where the biosynthesis of vitamin A from beta-carotene takes place.
• Vitamin A absorption requires bile salts, pancreatic lipase, and dietary fat.
• It is transported in the blood to the liver by the chylomicron fraction of the lymph.
• Vitamin A is stored in Kupffer cells of the liver mainly as the palmitate.
• Normal serum vitamin A is 80–300 Units per 100 mL (plasma range is 30–70 mcg per dl) and for carotenoids 270–753 Units per 100 mL.
• The normal adult liver contains approximately 100 to 300 micrograms per gram, mostly as retinol palmitate.
