Plasma-Lyte 56 and Dextrose

Uses

Magnesium acetate tetrahydrate is an ionic compound used for electrolyte replenishment and total parenteral nutrition (TPN) therapy.

Used as magnesium salf-containing laxatives to prevent constipation. It can bring synergistic effect to restore normal bowel function when using in combination with aluminum salts that induce bowel retention . Magnesium acetate tetrahydrate is used as a source of water and electrolytes when combined with dextrose and other salts to form intravenous infusions. This injection can be used for patients with carbohydrate or magnesium deficiency, insulin hypoglycemia, constipation or hypertension during pregnancy.

Potassium acetate is a medication used to treat hypokalemia.

Potassium is used to regulate hypokalemia as a primary condition or secondary to other medical conditions.

Sodium Chloride Nasal Drops is used for dry nasal membranes including dry nose resulting from cold and allergy medications. It moistens dry nasal passages from dry climates or from airplane travel, may help dissolve mucus from study noses and clears the nose after surgery. This sterile saline solution is also used to cleanse various parts of the body (wounds, body cavities) and medical equipment (e.g., bandages, catheters, drainage tubes). It is also used as a mixing solution (diluent) for other medications used to irrigate the body (e.g., bacitracin, polymyxin).

How Plasma-Lyte 56 and Dextrose works

Magnesium ions electrostatically stabilize the adenylyl cyclase complex and enhance its catalytic actions and production of cAMP. They also regulate the level of phosphorylation in various pathways by formation of transition state of phosphoryl transfer reaction by protein kinases and stabilize ATP binding to protein kinases via electrostatic interactions . Many metabolic enzymes involved in glycolysis and Krebs cycle are magnesium-dependent. Magnesium-containing laxatives cause diarrhea through water retention and increased fecal mass that stimulates peristalsis. When used as an electrolyte supplementation, magnesium acetate tetrahydrate induces diuresis and metabolic alkalinizing effect. Magnesium ions enhance reactivity of arteries to vasoconstrictors, promotes vasoconstriction, and increases peripheral resistance, leading to increased blood pressure through potential competition with calcium ions in the vascular system. Magnesium ions also regulate other ions entering and exiting the cell membrane by acting as a ligand in N-methyl-D-aspartate receptor.

Potassium is the major cation (positive ion) inside animal cells, while sodium is the major cation outside animal cells. The concentration differences of these charged particles causes a difference in electric potential between the inside and outside of cells, known as the membrane potential. The balance between potassium and sodium is maintained by ion pumps in the cell membrane. The cell membrane potential created by potassium and sodium ions allows the cell generate an action potential—a "spike" of electrical discharge. The ability of cells to produce electrical discharge is critical for body functions such as neurotransmission, muscle contraction, and heart function. Potassium is also an essential mineral needed to regulate water balance, blood pressure and levels of acidity.

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.

Dosage

Plasma-Lyte 56 and Dextrose dosage

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

Use in Children: Safe for pediatrics

Side Effects

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

Toxicity

Predicted oral LD50 value is >2000mg/kg. In case of mild to moderate toxicity, it may cause irritation in case of skin or eye contact,and nausea or vomiting from ingestion and inhalation. In overdose, magnesium impairs neuromuscular transmission, manifested as weakness and hyporeflexia. Early manifestations of severe toxicity are lethargy, hyporeflexia, followed by weakness, paralysis, hypotension, ECG changes (prolonged PR and QRS intervals), CNS depression, seizures, and respiratory depression.

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.

Volume of Distribution

Magnesium ions display approximate volume of distribution of 0.2 to 0.4 L/kg

The volume of distribution is 0.64 L/kg.

Elimination Route

Intestinal absorption is achieved mainly through passive diffusion.

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.

Half Life

Elimination half-life has been reported to be 27.7 hours following an overdose of 400mEq magnesium in an adult.

17 minutes

Elimination Route

Mainly renal exctretion, where up to 97% of magnesium may be excreted renally during hypermagnesemia.

Mostly urine but also skin and feces.

Substantially excreted by the kidneys.

Pregnancy & Breastfeeding use

It is unknown if this medication passes into breast milk. Consult with your doctor before breast-feeding.

Contraindication

Tell your doctor about your medical history, especially of heart problems (e.g., congestive heart failure), lung problems (pulmonary edema), kidney problems, low levels of potassium (hypokalemia), high levels of sodium (hypernatremia), and any allergies.
