Beta Carotene

About Beta Carotene
A natural precursor to Vitamin A.
Mechanism of Action of Beta Carotene
Beta-carotene acts as the precursor of Vitamin A and in the body it is converted in to Vitamin A. Vitamin A is required for a variety of physiological functions in the body such as: - 1).Proper functioning of retina and formation of pigment Rhodopsin during dark adaptation. 2).promotes differentiation and maintains structural integrity of epithelia over the body and also retard the malignancies of epithelial structures.3).Promotes mucous secretion. 4).Inhibits keratinization, 5). Maintains proper bone growth, 6).Maintenance of spermatogenesis, 7).Supports foetal development, 8).Improves resistance to infection. It is required for proper antibody response, normal lymphocyte proliferation and killer cell function.
Pharmacokinets of Beta Carotene
Absorption: Completely absorbed normally. Steatorrhoea, bile deficiency, and protein poor diet adversely affects the absorption and absorption requires bile salts, pancreatic lipase, and dietary fat.
Distribution: Stored primarily as palmitate in kupffer`s cells in liver. Circulates in the form of specific alpha-1 protein; retinol binding protein and transported to cellular retinol binding protein of target cells.
Metabolism: Metabolized in the liver.
Excretion: Excreted mainly through bile and a small amount is excreted through urine.

Indications for Beta Carotene
1. Vitamin A deficiency
2. Xerophthalmia
3. Acne
4. Ichthyosis
5. Bitot`s spots
6. Night blindness
Interactions for Beta Carotene
Cholestyramine: Absorption of Vitamin A is reduced due to reduced availability of fat stabilizing bile salts.
Mineral oil: Interferes with intestinal absorption of Vitamin A.
Oral Contraceptives: Plasma Vitamin A levels are significantly increased.
Typical Dosage for Beta Carotene
Severe vitamin A deficiency with xerophthalmia: 500000 IU daily for 3 days followed by 50000 IU daily for 14 days. Then maintenance dosage of 10000 to 20000 IU for 2months followed by adequate dietary nutrition and RDA vitamin A supplements.
Severe vitamin A deficiency: 100000 IU daily for 3 days followed by 50000 IU daily for 14 days. Then maintenance dosage of 10000 to 20000 IU for 2months followed by adequate dietary nutrition and RDA vitamin A supplements.
Children: 5000 to 10000 IU daily for 14 days.
Schedule of Beta Carotene
C1 (Oral)
C (Parenteral)
Storage Requirements for Beta Carotene
Store in a well closed, airtight container in a cool dry place.
Effects of Missed Dosage of Beta Carotene
Take the missed dose as soon as noticed and if it is the time for next dose then skip the missed dose. Continue the regular schedule. Do not double the dose.
Effects of Overdose of Beta Carotene
Discontinue the vitamin A if hypercalcaemia persists and administer I.V. saline, prednisolone, and calcitonin if required. Monitor hepatic function tests to detect liver damage.

Calcium

About Calcium
Calcium is necessary for cardiac function, muscle contraction, nervous activity, coagulation of blood and for maintaining structural integrity of cell membranes.
Plasma concentration of calcium is kept in normal range by three endocrine factors which control metabolism of calcium. These are (a) Parathyroid hormone, (b) Calcitonin, (c) Vitamin D. Calcium in plasma is bound to albumin, is complexed with anions (e.g. phosphate) and as diffusible ionic calcium. The physiological effects are exerted by ionic calcium. The predominant source of calcium is dairy products and the daily intake varies from 200 - 2500 mg. Adequate calcium intake is particularly important during periods of bone growth in childhood and adolescence and during pregnancy and lactation.
Patients with advanced renal insufficiency exhibit phosphate retention and some degree of hyperphosphataemia. The retention of phosphate plays a pivotal role in causing secondary hyperparathyroidism associated with osteodystrophy and soft tissue calcification. Calcium acetate, when taken with meals, combines with dietary phosphate to form insoluble calcium phosphate which is excreted in the faeces.
Deficiency signs and symptoms: Osteoporosis, pathological fractures, brittle nails and hair.
Mechanism of Action of Calcium
Calcium is essential for maintaining the functional integrity of nervous, muscular, and skeletal system. It controls excitability of nerves and muscles and regulates permeability of cell membrane. It also regulates cell adhesion and maintains integrity of cell membrane. Calcium acts as intracellular messenger for hormones, autacoids, and transmitters. It is required for excitation-contraction coupling in all types of muscle and excitation-secretion coupling in exocrine and endocrine glands. It is essential for release of transmitters from nerve endings and other release reactions. It is also essential for impulse generation in heart and determines level of automaticity and
A-V conduction. Calcium is also required for blood-coagulation.
Pharmacokinets of Calcium
Absorption: Actively absorbed from gastrointestinal tract in an ionized form; and vitamin D in it`s active form is required for calcium absorption, Distribution: Distributed mainly in to skeletal tissue (99%) and 1% is distributed equally between the intracellular and extra cellular fluid. CSF levels are about half of the serum calcium levels, Metabolism: Not significantly metabolized in the body, Excretion: Excreted mainly through faeces and a small amount is excreted through urine.
