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.

Schedule of Calcium
N/A
Storage Requirements for Calcium
Store in a well closed container in a cool and dry place. Protect from light.


Effects of Missed Dosage of Calcium
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 Calcium
Remove calcium from stomach by induced emesis and gastric lavage. Provide symptomatic treatment and supportive measures.

Phosphorus

About Phosphorus
Essential nutritional element , Mineral.
Mechanism of Action of Phosphorus
The second most abundant mineral in the body, phosphorus is needed for bone growth, kidney function and cell growth. It also plays a role in maintaining the body`s acid-alkaline balance. Phosphorus is found in many foods, but in order to be properly utilized, it must be in proper balance with magnesium and calcium in the blood. Excessive levels of phosphorus in the blood, often due to the consumption of soft drinks containing phosphoric acid, can lead to calcium loss and to cravings for sugar and alcohol; too little phosphorus inhibits calcium absorption and can lead to osteoporosis. Best sources are animal products, whole grains, legumes and nuts.
