Tumscalcium acetatecalcium carbonatecalcium chloridecalcium citratecalcium gluconatecalcium lactatetricalcium phosphatePharmacologic class: Mineral Therapeutic class: Dietary supplement, electrolyte replacement agent Pregnancy risk category C (calcium acetate, chloride, glubionate, gluceptate, phosphate), NR (calcium carbonate, citrate, gluconate, lactate) ActionIncreases serum calcium level through direct effects on bone, kidney, and GI tract. Decreases osteoclastic osteolysis by reducing mineral release and collagen breakdown in bone. AvailabilityCalcium acetate- Gelcaps: 667 mg Tablets: 667 mg Calcium carbonate- Capsules: 1,250 mg Lozenges: 600 mg Oral suspension: 1,250 mg Powder: 6.5 g Tablets: 650 mg, 1,250 mg, 1,500 mg Tablets (chewable): 750 mg, 1,000 mg, 1,250 mg Tablets (gum): 300 mg, 450 mg, 500 mg Calcium chloride- Injection: 10% solution Calcium citrate- Tablets: 950 mg Calcium gluceptate- Injection: 22% solution Calcium gluconate- Injection: 10% solution Tablets: 500 mg, 650 mg, 975 mg Calcium lactate- Tablets: 325 mg, 650 mg Tricalcium phosphate- Tablets: 600 mg Indications and dosages➣ Hypocalcemic emergency Adults: 7 to 14 mEq I.V. of 10% calcium gluconate solution, 2% to 10% calcium chloride solution, or 22% calcium gluceptate solution Children: 1 to 7 mEq calcium gluconate I.V. Infants: Up to 1 mEq calcium gluconate I.V. ➣ Hypocalcemic tetany Adults: 4.5 to 16 mEq calcium gluconate I.V., repeated as indicated until tetany is controlled Children: 0.5 to 0.7 mEq/kg calcium gluconate I.V. three to four times daily as indicated until tetany is controlled Neonates: 2.4 mEq/kg calcium gluconate I.V. daily in divided doses ➣ Cardiac arrest Adults: 0.027 to 0.054 mEq/kg calcium chloride I.V., 4.5 to 6.3 mEq calcium gluceptate I.V., or 2.3 to 3.7 mEq calcium gluconate I.V. Children: 0.27 mEq/kg calcium chloride I.V., repeated in 10 minutes if needed. Check calcium level before giving additional doses. ➣ Magnesium intoxication Adults: Initially, 7 mEq I.V.; subsequent dosages based on patient response ➣ Exchange transfusions Adults: 1.35 mEq calcium gluconate I.V. with each 100 ml of citrated blood ➣ Hyperphosphatemia in patients with end-stage renal disease Adults: Two tablets P.O. daily, given in divided doses t.i.d. with meals. May increase gradually to bring serum phosphate level below 6 mg/dl, provided hypercalcemia doesn't develop. ➣ Dietary supplement Adults: 500 mg to 2 g P.O. daily Off-label uses• Osteoporosis Contraindications• Hypersensitivity to drug • Ventricular fibrillation • Hypercalcemia and hypophosphatemia • Cancer • Renal calculi • Pregnancy or breastfeeding PrecautionsUse cautiously in: • renal insufficiency, pernicious anemia, heart disease, sarcoidosis, hyperparathyroidism, hypoparathyroidism • history of renal calculi • children. AdministrationSee When infusing I.V., don't exceed a rate of 200 mg/minute. • Keep patient supine for 15 minutes after I.V. administration to prevent orthostatic hypotension. • Administer P.O. doses 1 to 1½ hours after meals. • Know that I.M. or subcutaneous administration is never recommended. • Be aware that I.V. route is preferred in children. • Be alert for extravasation, which causes tissue necrosis. Adverse reactionsCNS: headache, weakness, dizziness, syncope, paresthesia CV: mild blood pressure decrease, bradycardia, arrhythmias, cardiac arrest (with rapid I.V. injection) GI: nausea, vomiting, diarrhea, constipation, epigastric pain or discomfort GU: urinary frequency, renal calculi Metabolic: hypercalcemia Musculoskeletal: joint pain, back pain Respiratory: dyspnea Skin: rash Other: altered or chalky taste, excessive thirst, allergic reactions (including facial flushing, swelling, tingling, tenderness in hands, and anaphylaxis) InteractionsDrug-drug. Atenolol, fluoroquinolones, tetracycline: decreased bioavailability of these drugs Calcium channel blockers: decreased calcium effects Cardiac glycosides: increased risk of cardiac glycoside toxicity Iron salts: decreased iron absorption Sodium polystyrene sulfonate: metabolic alkalosis Verapamil: reversal of verapamil effects Drug-diagnostic tests. Calcium: increased level Drug-food. Foods containing oxalic acid (such as spinach), phytic acid (such as whole grain cereal), or phosphorus (such as dairy products): interference with calcium absorption Patient monitoring• Monitor calcium levels frequently, especially in elderly patients. Patient teaching• Instruct patient to consume plenty of milk and dairy products during therapy. • Refer patient to dietitian for help in meal planning and preparation. • As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, and foods mentioned above. calcium carbonate(kal-see-um kar-bo-nate) calciumcarbonate,Alka-Mints(trade name),Amitone(trade name),Apo-Cal(trade name),BioCal(trade name),Calcarb(trade name),Calci-Chew(trade name),Calciday(trade name),Calcilac(trade name),Calci-Mix(trade name),Calcite(trade name),Calglycine(trade name),Cal-Plus(trade name),Calsan(trade name),Caltrate(trade name),Chooz(trade name),Dicarbosil(trade name),Equilet(trade name),Gencalc(trade name),Liqui-Cal(trade name),Liquid Cal-600(trade name),Maalox Antacid Caplets(trade name),Mallamint(trade name),Mylanta Lozenges(trade name),Nephro-Calci(trade name),Nu-Cal(trade name),Os-Cal(trade name),Oysco(trade name),Oyst-Cal(trade name),Oystercal(trade name),Rolaids Calcium Rich(trade name),Surpass(trade name),Surpass Extra Strength(trade name),Titralac(trade name),Tums(trade name),Tums E-X(trade name)ClassificationTherapeutic: mineral electrolyte replacements supplementsIndicationsActionTherapeutic effectsPharmacokineticsTime/action profile (effects on serum calcium)

InteractionsDrug-Drug interactionHypercalcemia increases the risk of digoxin toxicity.Chronic use with antacids in renal insufficiency may lead to milk-alkali syndrome.Ingestion by mouth decreases the absorption of orally administered tetracyclines, fluoroquinolones, phenytoin, and iron salts.Excessive amounts may decrease the effects of calcium channel blockers.Decreases absorption of etidronate and risedronate (do not take within 2 hr of calcium supplements).May decrease the effectiveness of atenolol.Concurrent use with diuretics (thiazide) may result in hypercalcemia.May decrease the ability of sodium polystyrene sulfonate to decrease serum potassium.Cereals, spinach, or rhubarb may decrease the absorption of calcium supplements.Calcium acetate should not be given concurrently with other calcium supplements.Route/Dosage1 gram of calcium carbonate contains 400 mg elemental calcium (20 mEq calcium). Doses expressed in terms of elemental calcium.AvailabilityNursing implicationsNursing assessment
