Calcium chloride is an ionic compound of calcium and chlorine. It is highly soluble in water and it is deliquescent. It is a salt that is solid at room temperature, and it behaves as a typical ionic halide. It has several common applications such as brine for refrigeration plants, ice and dust control on roads, and in cement. It can be produced directly from limestone, but large amounts are also produced as a by-product of the Solvay process. Because of its hygroscopic nature, it must be kept in tightly-sealed containers.

Calcium is the fifth most abundant element in the body and the major fraction is in the bony structure. Calcium plays important physiological roles, many of which are poorly understood. It is essential for the functional integrity of the nervous and muscular systems. It is necessary for normal cardiac function and is one of the factors that operates in the mechanisms involved in the coagulation of blood.

Magnesium chloride salts are highly soluble in water and the hydrated form of magnesium chloride can be extracted from brine or sea water.

Magnesium is important as a cofactor in many enzymatic reactions in the body involving protein synthesis and carbohydrate metabolism (at least 300 enzymatic reactions require magnesium). Actions on lipoprotein lipase have been found to be important in reducing serum cholesterol and on sodium/potassium ATPase in promoting polarization (eg, neuromuscular functioning).

Potassium chloride is a major cation of the intracellular fluid. It plays an active role in the conduction of nerve impulses in the heart, brain and skeletal muscle; contraction of cardiac skeletal and smooth muscles; maintenance of normal renal function, acid-base balance, carbohydrate metabolism and gastric secretion.

The potassium ion is in the principle intracellular cation of most body tissues. Potassium ions participate in a number of essential physiological processes including the maintenance of intracellular tonicity, the transmission of nerve impulses, the contraction of cardiac, skeletal and smooth muscle, and the maintenance of normal renal function. The intracellular concentration of potassium is approximately 150 to 160 mEq per liter. The normal adult plasma concentration is 3.5 to 5 mEq per liter. An active ion transport system maintains this gradient across the plasma membrane. Potassium is a normal dietary constituent and under steady-state conditions the amount of potassium absorbed from the gastrointestinal tract is equal to the amount excreted in the urine. The usual dietary intake of potassium is 50 to 100 mEq per day. Potassium depletion will occur whenever the rate of potassium loss through renal excretion and/or loss from the gastrointestinal tract exceeds the rate of potassium intake. Such depletion usually develops as a consequence of therapy with diuretics, primarily or secondary hyperaldosteronism, diabetic ketoacidosis, or inadequate replacement of potassium in patients on prolonged parenteral nutrition. Depletion can develop rapidly with severe diarrhea, especially if associated with vomiting. Potassium depletion due to these causes is usually accompanied by concomitant loss of chloride and is manifested by hypokalemia and metabolic alkalosis. Potassium depletion may produce weakness, fatigue, disturbances of cardiac rhythm (primarily ectopic beats), prominent U-waves in the electrocardiogram, and, in advanced cases, flaccid paralysis and/or impaired ability to concentrate urine. If potassium depletion associated with metabolic alkalosis cannot be managed by correcting the fundamental cause of the deficiency, e.g., where the patient requires long-term diuretic therapy, supplemental potassium in the form of high potassium food or potassium chloride may be able to restore normal potassium levels. In rare circumstances (e.g., patients with renal tubular acidosis) potassium depletion may be associated with metabolic acidosis and hyperchloremia. In such patients, potassium replacement should be accomplished with potassium salts other than the chloride, such as potassium bicarbonate, potassium citrate, potassium acetate, or potassium gluconate.

Sodium Acetate is chemically designated CH3COONa, a hygroscopic powder very soluble in water. Sodium acetate could be used as additives in food, industry, concrete manufacture, heating pads and in buffer solutions. Medically, sodium acetate is important component as an electrolyte replenisher when given intravenously. It is mainly indicated to correct sodium levels in hyponatremic patients. It can be used also in metabolic acidosis and for urine alkalinization.

Sodium is the principal cation of extracellular fluid. It comprises more than 90% of total cations at its normal plasma concentration of approximately 140 mEq/liter. The sodium ion exerts a primary role in controlling total body water and its distribution. Acetate ions acts as hydrogen ion acceptor which is alternative to bicarbonate.

Sodium chloride is the major extracellular cation. It is important in electrolyte and fluid balance, osmotic pressure control and water distribution as it restores sodium ions. It is used as a source of electrolytes and water for hydration, treatment of metabolic acidosis, priming solution in haemodialysis and treatment of hyperosmolar diabetes. It is also used as diluents for infusion of compatible drug additives.

Sodium, the major cation of the extracellular fluid, functions primarily in the control of water distribution, fluid balance, and osmotic pressure of body fluids. Sodium is also associated with chloride and bicarbonate in the regulation of the acid-base equilibrium of body fluid.Chloride, the major extracellular anion, closely follows the metabolism of sodium, and changes in the acid-base balance of the body are reflected by changes in the chloride concentration.

Sodium citrate is the sodium salt of citric acid. It is white, crystalline powder or white, granular crystals, slightly deliquescent in moist air, freely soluble in water,practically insoluble in alcohol. Like citric acid, it has a sour taste.From the medical point of view, it is used as alkalinizing agent. It works by neutralizing excess acid in the blood and urine. It has been indicated for the treatment of metabolic acidosis.

Citrate prevents activation of the clotting cascade by chelating calcium ions. Citrate neutralizes acid in the stomach and urine, raising the pH .

How Lacrimist Tube works

Calcium chloride in water dissociates to provide calcium (Ca²⁺) and chloride (Cl^-) ions. They are normal constituents of the body fluids and are dependent on various physiological mechanisms for maintenance of balance between intake and output. For hyperkalemia, the influx of calcium helps restore the normal gradient between threshold potential and resting membrane potential.

Mechanism of action of magnesium chloride studied in 10 adult volunteers. Results suggested magnesium ion in duodenum is relatively weak stimulus to pancreas and gall bladder. It is weak stimulant to cholecystokinin release and inhibits net jejunal water absorption. The oral administration of a single 800 mg dose of magnesium chloride in healthy volunteers resulted in a diminished rate of intraluminal lipid and protein digestion. The most pronounced effect of magnesium chloride, however, was a decreased gastric emptying rate of both test meals. After correction for gastric emptying, no differences were noted in intraluminal lipid or protein digestion. Therefore, the lower lipid levels noted after magnesium supplementation are unlikely to be the result of altered lipid assimilation. Magnesium chloride slows gastric emptying but does not influence lipid digestion.

Supplemental potassium in the form of high potassium food or potassium chloride may be able to restore normal potassium levels.

It works as a source of sodium ions especially in cases of hyponatremic patients. Sodium has a primary role in regulating extracellular fluid volume. It controls water distribution, fluid and electrolyte balance and the osmotic pressure of body fluids. Sodium is also involved in nerve conduction, muscle contraction, acid-base balance and cell nutrient uptake.

Sodium and chloride — major electrolytes of the fluid compartment outside of cells (i.e., extracellular) — work together to control extracellular volume and blood pressure. Disturbances in sodium concentrations in the extracellular fluid are associated with disorders of water balance.

Citrate chelates free calcium ions preventing them from forming a complex with tissue factor and coagulation factor VIIa to promote the activation of coagulation factor X . This inhibits the extrinsic initiation of the coagulation cascade. Citrate may also exert an anticoagulant effect via a so far unknown mechanism as restoration of calcium concentration does not fully reverse the effect of citrate . Citrate is a weak base and so reacts with hydrochloric acid in the stomach to raise the pH. It it further metabolized to bicarbonate which then acts as a systemic alkalizing agent, raising the pH of the blood and urine . It also acts as a diuretic and increases the urinary excretion of calcium.

Dosage

Lacrimist Tube dosage

Oral:Dosage must be adjusted to the individual needs of each patient.

Adults: In severe deficiencies 3-6 tablets or 4-8 teaspoonful or 25-50 mmol per day orally in divided doses for some days with fruit juice, sweet or plain water.
Children: ½-1 teaspoonful twice daily or 1-3 mmol/kg body weight a day in several divided doses.

Patient should take Potassium chloride with meals.

Intravenous:

Severe acute hypokalaemia:

Adult: If serum potassium level >2.5 mEq/L, give at a rate not exceeding 10 mEq/hr in a concentration of up to 40 mEq/L. Max dose: 200 mEq/24 hr. If serum potassium level <2 mEq/L, may infuse at a rate of up to 40 mEq/hr. Continuous cardiac monitoring is essential. Max dose: 400 mEq/24 hr.

75 mg KCl equivalent to 1 mmol K+

Infants, children & adults: 2-6 drops into each nostril as needed daily

Use in Children: Safe for pediatrics

Side Effects

GI ulceration (sometimes with haemorrhage and perforation or with late formation of strictures) following the use of enteric-coated K chloride preparation; hyperkalaemia. Oral: Nausea, vomiting, diarrhoea and abdominal cramps. IV: Pain or phloebitis; cardiac toxicity.

No side Effects are expected to occur. However stinging, sneezing, increased nasal discharge, or salty taste may occur in some cases.

Toxicity

Too rapid injection may produce lowering of blood pressure and cardiac syncope. Persistent hypercalcemia from overdosage of calcium is unlikely because of rapid excretion.

Mouse LD50 775mg/kg (intraperitoneal) Mouse LD50 : 7600mg/kg (oral) Rat LD 50 : 8100mg/kg (oral) Rat LD50 176mg/kg (intravenous) Severe toxicity occurs most often after intravenous infusions. It can also occur after chronic excessive oral doses, often in patients with renal insufficiency. Early manifestations are lethargy, hyporeflexia, followed by weakness, paralysis, hypotension, ECG changes (prolonged PR and QRS intervals), CNS depression, seizures, and respiratory depression. In overdose, magnesium impairs neuromuscular transmission, manifested as weakness and hyporeflexia.

The administration of oral potassium salts to persons with normal excretory mechanisms for potassium rarely causes serious hyperkalemia. However, if excretory mechanisms are impaired, of if potassium is administered too rapidly intravenously, potentially fatal hyperkalemia can result. It is important to recognize that hyperkalemia is usually asymptomatic and may be manifested only by an increased serum potassium concentration (6.5-8.0 mEq/L) and characteristic electrocardiographic changes (peaking of T-waves, loss of P-wave, depression of S-T segment, and prolongation of the QT interval). Late manifestations include muscle paralysis and cardiovascular collapse from cardiac arrest (9-12 mEq/L).

LD50: 25956 mg/kg (Rat.)

The rare inadvertent intravascular administration or rapid intravascular absorption of hypertonic sodium chloride can cause a shift of tissue fluids into the vascular bed, resulting in hypervolemia, electrolyte disturbances, circulatory failure, pulmonary embolism, or augmented hypertension.

Overdose toxicity is mainly due to alkalosis as well as tetany or depressed heart function due to lack of free calcium .

Precaution

Renal or adrenocortical insufficiency; cardiac disease; acute dehydration; extensive tissue destruction. Pregnancy. Ensure adequate urine output; monitor plasma-potassium and other electrolyte concentrations. Discontinue treatment if severe nausea, vomiting or abdominal distress develops. Accumulation of potassium may occur in renal impairment.

Interaction

Potassium-sparing diuretics, ACE inhibitors, ciclosporin and potassium-containing drugs. Antimuscarinics delay gastric emptying time consequently increasing risk of GI adverse effects esp of solid oral dosage forms.

Volume of Distribution

18-54 min

Clearance

Maximum magnesium clearance is directly proportional to creatinine clearance.

Total clearance of 313-1107mL/min .

Elimination Route

Approximately 80% of body calcium is excreted in the feces as insoluble salts; urinary excretion accounts for the remaining 20%.

Magnesium is excreted in urine. Unabsorbed magnesium is excreted in feces

Potassium is a normal dietary constituent and, under steady-state conditions, the amount of potassium absorbed from the gastrointestinal tract is equal to the amount excreted in the urine. Potassium depletion will occur whenever the rate of potassium loss through renal excretion and/or loss from the gastrointestinal tract exceeds the rate of potassium intake.

Both the sodium and bicarbonate ions are excreted mainly in the urine. Some sodium is excreted in the feces, and small amounts may also be excreted in saliva, sweat, bile and pancreatic secretions.
