Description

Magnesium chloride salts are typical ionic halides, being highly soluble in water. The hydrated magnesium chloride can be extracted from brine or sea water.

Indication

Magnesium chloride is used in several medical and topical (skin related) applications. Magnesium chloride usp, anhydrous uses as electrolyte replenisher, pharmaceutic necessity for hemodialysis and peritoneal dialysis fluids.

Mechanism of Action

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.

Pharmacokinetics

Absorption
Oral: Inversely proportional to amount ingested; 40% to 60% under controlled dietary conditions; 15% to 36% at higher doses
Distribution
Bone (50% to 60%); extracellular fluid (1% to 2%)
Metabolism
Magnesium levels are efficiently regulated by the kidneys. Magnesium also undergoes efficient enterohepatic circulation
Elimination

Clearance

Maximum magnesium clearance is directly proportional to creatinine clearance.

Toxicity

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.

Description

A white crystal or crystalline powder used as an electrolyte replenisher, in the treatment of hypokalemia, in buffer solutions, and in fertilizers and explosives.

Indication

For use as an electrolyte replenisher and in the treatment of hypokalemia.

Mechanism of Action

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

Pharmacokinetics

Absorption
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.
Distribution
Metabolism
Elimination

Toxicity

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).

Description

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.

Indication

Injection, USP 40 mEq is indicated as a source of sodium, for addition to large volume intravenous fluids to prevent or correct hyponatremia in patients with restricted or no oral intake. It is also useful as an additive for preparing specific intravenous fluid formulas when the needs of the patient cannot be met by standard electrolyte or nutrient solutions. Sodium acetate and other bicarbonate precursors are alkalinising agents, and can be used to correct metabolic acidosis, or for alkalinisation of the urine.

Mechanism of Action

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.

Pharmacokinetics

Absorption
It is readily available in the circulation after IV administration.
Distribution
Metabolism
In liver, sodium acetate is being metabolized into bicarbonate. To form bicarbonate, acetate is slowly hydrolyzed to carbon dioxide and water, which are then converted to bicarbonate by the addition of a hydrogen ion.
Elimination

Toxicity

LD50: 25956 mg/kg (Rat.)

Description

Sodium chloride, also known as salt, common salt, table salt or halite, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. Sodium chloride is the salt most responsible for the salinity of seawater and of the extracellular fluid of many multicellular organisms. It is listed on the World Health Organization Model List of Essential Medicines.

Indication

This intravenous solution is indicated for use in adults and pediatric patients as a source of electrolytes and water for hydration. Also, designed for use as a diluent and delivery system for intermittent intravenous administration of compatible drug additives.

Mechanism of Action

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.

Pharmacokinetics

Absorption
Absorption of sodium in the small intestine plays an important role in the absorption of chloride, amino acids, glucose, and water. Chloride, in the form of hydrochloric acid (HCl), is also an important component of gastric juice, which aids the digestion and absorption of many nutrients.
Distribution
The volume of distribution is 0.64 L/kg.
Metabolism
The salt that is taken in to gastro intestinal tract remains for the most part unabsorbed as the liquid contents pass through the stomach and small bowel. On reaching the colon this salt, together with the water is taken in to the blood. As excesses are absorbed the kidney is constantly excreting sodium chloride, so that the chloride level in the blood and tissues remains fairly constant.Further more, if the chloride intake ceases, the kidney ceases to excrete chlorides. Body maintains an equilibrium retaining the 300gm of salt dissolved in the blood and fluid elements of the tissue dissociated into sodium ions and chloride ions.
Elimination

Toxicity

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.
