Corvatrol Injection: Package Insert / Prescribing Info

Corvatrol Injection Description

Bacteriostatic Sodium Chloride Injection, USP, 0.9% is a sterile, nonpyrogenic, isotonic solution.

Each mL contains: Sodium chloride 9 mg; benzyl alcohol 0.9%; Water for Injection q.s. Hydrochloric acid and/or sodium hydroxide may have been added for pH adjustment (pH 4.5-7.0).

Sodium chloride occurs as colorless cubic crystals or white crystalline powder and has a saline taste. Sodium chloride is freely soluble in water. It is soluble in glycerin and slightly soluble in alcohol.

The empirical formula for sodium chloride is NaCl and the molecular weight is 58.44.

Corvatrol Injection - Clinical Pharmacology

Sodium chloride in water dissociates to provide sodium (Na+) and chloride (Cl-) ions. These ions are normal constituents of the body fluids (principally extracellular) and are essential for maintaining electrolyte balance.

The distribution and excretion of sodium (Na+) and chloride (Cl-) are largely under the control of the kidney which maintains a balance between intake and output.

The small volume of fluid and amount of sodium chloride provided by Bacteriostatic Sodium Chloride Injection, USP, 0.9%, when used only as a vehicle for parenteral injection of drugs, is unlikely to exert a significant effect on fluid and electrolyte balance except possibly in very small infants.

Water is an essential constituent of all body tissues and accounts for approximately 70% of total body weight. Average normal adult daily requirement ranges from two to three liters (1 to 1.5 liters each of insensible water loss by perspiration and urine production).

Water balance is maintained by various regulatory mechanisms. Water distribution depends primarily on the concentration of electrolytes in the body compartments and sodium (Na+) plays a major role in maintaining physiologic equilibrium.

Indications and Usage for Corvatrol Injection

These parenteral preparations are indicated only for diluting or dissolving drugs for intravenous, intramuscular or subcutaneous injection, according to instructions of the manufacturer of the drug to be administered. NOT FOR INHALATION.

Contraindications

Due to potential toxicity of benzyl alcohol in newborns, Bacteriostatic Sodium Chloride Injection, USP, 0.9% containing benzyl alcohol must not be used in this patient population.

Bacteriostatic Sodium Chloride Injection, USP, 0.9% should not be used for fluid or sodium chloride replacement.

Warnings

Benzyl alcohol as a preservative in Bacteriostatic Sodium Chloride Injection, USP, 0.9% has been associated with toxicity in newborns. Data is unavailable on the toxicity of other preservatives in this age group. Preservative-free Sodium Chloride Injection, USP, 0.9% should be used for flushing intravascular catheters. Where a sodium chloride solution is required for preparing or diluting medications for use in newborns, only preservative-free Sodium Chloride Injection, USP, 0.9% should be used.

Precautions

Adverse Reactions/Side Effects

Reactions which may occur because of Bacteriostatic Sodium Chloride Injection, USP, 0.9%, added drugs or the technique of reconstitution or administration include febrile response, local tenderness, abscess, tissue necrosis or infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection and extravasation.

If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate countermeasures and if possible, retrieve and save the remainder of the unused vehicle for examination.

Although adverse reactions to intravenous, intramuscular or subcutaneous injection of 0.9% benzyl alcohol are not known to occur in man, experimental studies of small volume parenteral preparations containing 0.9% benzyl alcohol in several species of animals have indicated that an estimated intravenous dose up to 30 mL may be safely given to an adult without toxic effects. Administration of an estimated 9 mL to a 6 kg infant is potentially capable of producing blood pressure changes.

Overdosage

Use only as a diluent or solvent. This parenteral preparation is unlikely to pose a threat of sodium chloride or fluid overload except possibly in very small infants. In the event these should occur, reevaluate the patient and institute appropriate corrective measures. See PRECAUTIONS and ADVERSE REACTIONS.

Corvatrol Injection Dosage and Administration

NOT FOR INHALATION. Before Bacteriostatic Sodium Chloride Injection, USP, 0.9% is used as a vehicle for the administration of a drug, specific references should be checked for any possible incompatibility with sodium chloride or benzyl alcohol.

The volume of the preparation to be used for diluting or dissolving any drug for injection is dependent on the vehicle concentration, dose and route of administration as recommended by the manufacturer.

Isotonic solutions may be given subcutaneously, intravenously, and occasionally, intramuscularly.

Use Bacteriostatic Sodium Chloride Injection, USP, 0.9% with due regard for the compatibility of the benzyl alcohol it contains with the particular medicinal substance that is to be dissolved or diluted.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
