Indications
Ovit-A is used to treat conditions caused by Ovit-A deficiency, including eye problems such as night blindness and xerophthalmia, and skin-related problems such as changes in the skin, hair and nails. It may also be given alongside other treatment for illnesses of the mucous membranes, such as sinusitis and bronchitis, and in acne vulgaris, ichthyosis, Darier's disease, psoriasis and similar conditions. It helps meet the body's vitamin A needs during growth, supports resistance to infection and helps with night blindness. Ovit-A is also indicated to correct Ovit-A deficiency after diarrhoea and as a preventive measure against measles.
⚠️ Always consult a registered physician before taking any medicine.
Pharmacology
Beta-carotene, retinol, and retinal all show reliable vitamin A activity. Retinal and retinol exist in chemical equilibrium in the body and have equivalent antixerophthalmic activity. Retinal combines with the rod pigment opsin in the retina to form rhodopsin, which is needed for visual dark adaptation. Vitamin A prevents growth retardation and preserves the integrity of epithelial cells. Normal adult liver stores are enough to meet the body's vitamin A needs for about two years. Vitamin A is readily absorbed from the gastrointestinal tract, where it is also synthesized from beta-carotene. Its absorption depends on bile salts, pancreatic lipase, and dietary fat. It is carried in the blood to the liver by the chylomicron fraction of the lymph and is stored in the liver's Kupffer cells, mainly as retinol palmitate. Normal serum vitamin A levels are 80 to 300 units per 100 mL (a plasma range of 30 to 70 mcg per dL), and carotenoid levels are 270 to 753 units per 100 mL. The normal adult liver contains roughly 100 to 300 micrograms per gram, mostly in the form of retinol palmitate.
Pregnancy & Breastfeeding
Safety of amounts exceeding 6,000 Units of vitamin A daily during pregnancy has not been established at this time. The use of vitamin A in excess of the recommended dietary allowance may cause fetal harm when administered to a pregnant woman. Animal reproduction studies have shown fetal abnormalities associated with over-dosage in several species. Malformations of the central nervous system, the eye, the palate, and the urogenital tract are recorded. Vitamin Ain excess of the recommended dietary allowance is contraindicated in women who are or may become pregnant. If vitamin Ais used during pregnancy, or if the patient becomes pregnant while taking vitamin A, the patient should be apprised of the potential hazard to the fetus. The U.S. Recommended Daily Allowance (RDA) of vitamin A (5,000 Units) is recommended for nursing mothers.
