Dilosyn Expt

Uses

1. Expectorant in cough syrups.
2. The ammonium ion (NH4+) in the body plays an important role in the maintenance of acid-base balance. The kidney uses ammonium (NH4+) in place of sodium (Na+) to combine with fixed anions in maintaining acid-base balance, especially as a homeostatic compensatory mechanism in metabolic acidosis. The therapeutic effects of Ammonium Chloride depend upon the ability of the kidney to utilize ammonia in the excretion of an excess of fixed anions and the conversion of ammonia to urea by the liver, thereby liberating hydrogen (H+) and chloride (Cl–) ions into the extracellular fluid. Ammonium Chloride Injection, USP, after dilution in isotonic sodium chloride injection, may be indicated in the treatment of patients with: (1) hypochloremic states and (2) metabolic alkalosis.

Used for the symptomatic relief of hypersensitivity reactions and particularly for the control of pruritic skin disorders

Sodium citrate is an ingredient used for the anticoagulation of whole blood as part of automated apheresis procedures.

Used as an anticoagulant during plasmophoresis as well as a neutralizing agent in the treatment of upset stomach and acidic urine .

How Dilosyn Expt works

Ammonium chloride increases acidity by increasing the amount of hydrogen ion concentrations.

Ammonium chloride can be used as an expectorant due to its irritative action on the bronchial mucosa. This effect causes the production of respiratory tract fluid which in order facilitates the effective cough.

Methdilazine binds to the histamine H₁ receptor. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine.

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.

Toxicity

LD50 "Rat" after oral administration is: 1650 mg/kg. Overdosage of Ammonium Chloride has resulted in a serious degree of metabolic acidosis, disorientation, confusion and coma. If metabolic acidosis occur following overdosage, the administration of an alkalinizing solution such as sodium bicarbonate or sodium lactate will serve to correct the acidosis.

Patients administering Ammonium chloride should be watched to the signs of ammonia toxicity including (pallor, sweating, irregular breathing, bradycardia, cardiac arrhythmias, local and general twitching, tonic convulsions and coma). It should be used with caution in patients with high total CO2 and buffer base secondary to primary respiratory acidosis. Intravenous administration should be slow to avoid local irritation and toxic effects.

Symptoms of overdose include clumsiness or unsteadiness, convulsions, drowsiness, dryness of mouth, nose, or throat, feeling faint, flushing or redness of face, hallucinations, muscle spasms (especially of neck and back), restlessness, shortness of breath or troubled breathing, shuffling walk, tic-like movements of head and face, trembling and shaking of hands, and trouble in sleeping.

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