Overview

What is Physicians EZ Use B-12 Compliance?

Cyanocobalamin Injection, USP is a sterile solution of cyanocobalamin for intramuscular or subcutaneous use.

Each mL contains 1000 mcg cyanocobalamin; sodium chloride 0.9%; benzyl alcohol 1.5%; Water for Injection q.s. Hydrochloric acid and/or sodium hydroxide for pH adjustment if necessary (4.5-7.0).

Cyanocobalamin appears as dark, red crystals or as an amorphous or crystalline, red powder. It is very hygroscopic in the anhydrous form, and sparingly soluble in water (1:80). It is stable to autoclaving for short periods at 121°C. The Vitamin B coenzymes are very unstable in light.

The chemical name is 5,6-dimethyl-benzimidazolyl cyanocobamide. The cobalt content is 4.34%. The structural formula is represented below:

How should I use Physicians EZ Use B-12 Compliance?

Cyanocobalamin is indicated for Vitamin B deficiencies due to malabsorption which may be associated with the following conditions:

            Addisonian (pernicious) anemia

            Gastrointestinal pathology, dysfunction, or surgery, including gluten enteropathy or sprue, small bowel bacterial overgrowth, total or partial gastrectomy

            Fish tapeworm infestation

            Malignancy of pancreas or bowel

            Folic acid deficiency

It may be possible to treat the underlying disease by surgical correction of anatomic lesions leading to small bowel bacterial overgrowth, expulsion of fish tapeworm, discontinuation of drugs leading to vitamin malabsorption (see ), use of a gluten-free diet in nontropical sprue, or administration of antibiotics in tropical sprue. Such measures remove the need for long-term administration of cyanocobalamin.

Requirements of Vitamin B in excess of normal (due to pregnancy, thyrotoxicosis, hemolytic anemia, hemorrhage, malignancy, hepatic and renal disease) can usually be met with oral supplementation.

Cyanocobalamin injection is also suitable for the Vitamin B absorption test (Schilling test).

Avoid using the intravenous route. Use of this product intravenously will result in almost all of the vitamin being lost in the urine.

WARNING: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

Patients with early Leber’s disease (hereditary optic nerve atrophy) who were treated with cyanocobalamin suffered severe and swift optic atrophy.

Hypokalemia and sudden death may occur in severe megaloblastic anemia which is treated intensely.

Anaphylactic shock and death have been reported after parenteral Vitamin B administration. An intradermal test dose is recommended before cyanocobalamin injection is administered to patients suspected of being sensitive to this drug.

This product contains benzyl alcohol. Benzyl alcohol has been reported to be associated with a fatal ‘‘Gasping Syndrome’’ in premature infants.

What are the precautions of Physicians EZ Use B-12 Compliance?

General

Vitamin B deficiency that is allowed to progress for longer than three months may produce permanent degenerative lesions of the spinal cord. Doses of folic acid greater than 0.1 mg/day may result in hematologic remission in patients with Vitamin B deficiency. Neurologic manifestations will not be prevented with folic acid, and if not treated with Vitamin B, irreversible damage will result.

Doses of cyanocobalamin exceeding 10 mcg daily may produce hematologic response in patients with folate deficiency. Indiscriminate administration may mask the true diagnosis.

Information for Patients

Patients with pernicious anemia should be instructed that they will require monthly injections of Vitamin B for the remainder of their lives. Failure to do so will result in return of the anemia and in development of incapacitating and irreversible damage to the nerves of the spinal cord. Also, patients should be warned about the danger of taking folic acid in place of Vitamin B, because the former may prevent anemia but allow progression of subacute combined degeneration.

A vegetarian diet which contains no animal products (including milk products or eggs) does not supply any Vitamin B. Patients following such a diet should be advised to take oral Vitamin B regularly. The need for Vitamin B is increased by pregnancy and lactation. Deficiency has been recognized in infants of vegetarian mothers who were breast fed, even though the mothers had no symptoms of deficiency at the time.

Laboratory Tests

During the initial treatment of patients with pernicious anemia, serum potassium must be observed closely the first 48 hours and potassium replaced if necessary.

Hematocrit, reticulocyte count, Vitamin B, folate and iron levels should be obtained prior to treatment. Hematocrit and reticulocyte counts should be repeated daily from the 5th to 7th days of therapy and then frequently until the hematocrit is normal. If folate levels are low, folic acid should also be administered. If reticulocytes have not increased after treatment or if reticulocyte counts do not continue at least twice normal as long as the hematocrit is less than 35%, diagnosis or treatment should be reevaluated. Repeat determinations of iron and folic acid may reveal a complicating illness that might inhibit the response of the marrow.

Patients with pernicious anemia have about three times the incidence of carcinoma of the stomach as the general population, so appropriate tests for this condition should be carried out when indicated.

Drug/Laboratory Test Interactions

Persons taking most antibiotics, methotrexate and pyrimethamine invalidate folic acid and Vitamin B diagnostic blood assays.

Colchicine, para-aminosalicylic acid and heavy alcohol intake for longer than two weeks may produce malabsorption of Vitamin B.

Carcinogenesis, Mutagenesis

Long-term studies in animals to evaluate carcinogenic potential have not been done. There is no evidence from long-term use in patients with pernicious anemia that cyanocobalamin is carcinogenic. Pernicious anemia is associated with an increased incidence of carcinoma of the stomach, but this is believed to be related to the underlying pathology and not to treatment with cyanocobalamin.

Clinical Pharmacology

Vitamin B is essential to growth, cell reproduction, hematopoiesis, nucleoprotein and myelin synthesis.

Cyanocobalamin is quantitatively and rapidly absorbed from intramuscular and subcutaneous sites of injection; the plasma level of the compound reaches its peak within one hour after intramuscular injection. Absorbed Vitamin B is transported via specific B binding proteins, transcobalamin I and II to the various tissues. The liver is the main organ for Vitamin B storage.

Within 48 hours after injection of 100 or 1000 mcg of Vitamin B, 50 to 98% of the injected dose may appear in the urine. The major portion is excreted within the first eight hours. Intravenous administration results in even more rapid excretion with little opportunity for liver storage.

Gastrointestinal absorption of Vitamin B depends on the presence of sufficient intrinsic factor and calcium ions. Intrinsic factor deficiency causes pernicious anemia, which may be associated with subacute combined degeneration of the spinal cord. Prompt parenteral administration of Vitamin B prevents progression of neurologic damage.

The average diet supplies about 5 to 15 mcg/day of Vitamin B in a protein-bound form that is available for absorption after normal digestion. Vitamin B is not present in foods of plant origin, but is abundant in foods of animal origin. In people with normal absorption, deficiencies have been reported only in strict vegetarians who consume no products of animal origin (including no milk products or eggs).

Vitamin B is bound to intrinsic factor during transit through the stomach; separation occurs in the terminal ileum in the presence of calcium, and Vitamin B enters the mucosal cell for absorption. It is then transported by the transcobalamin binding proteins. A small amount (approximately 1% of the total amount ingested) is absorbed by simple diffusion, but this mechanism is adequate only with very large doses. Oral absorption is considered too undependable to rely on in patients with pernicious anemia or other conditions resulting in malabsorption of Vitamin B.

Cyanocobalamin is the most widely used form of Vitamin B, and has hematopoietic activity apparently identical to that of the antianemia factor in purified liver extract. Hydroxocobalamin is equally as effective as cyanocobalamin, and they share the cobalamin molecular structure.

Non-Clinical Toxicology

The hypoglycemic action of sulfonylureas may be potentiated by certain drugs including nonsteroidal anti-inflammatory agents and other drugs that are highly protein bound, salicylates, sulfonamides, chloramphenicol, probenecid, coumarins, monoamine oxidase inhibitors, and beta adrenergic blocking agents. When such drugs are administered to a patient receiving glyburide tablets, the patient should be observed closely for hypoglycemia. When such drugs are withdrawn from a patient receiving glyburide tablets, the patient should be observed closely for loss of control.

An increased risk of liver enzyme elevations was observed in patients receiving glyburide concomitantly with bosentan. Therefore concomitant administration of glyburide tablets and bosentan is contraindicated.

Certain drugs tend to produce hyperglycemia and may lead to loss of control. These drugs include the thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blocking drugs, and isoniazid. When such drugs are administered to a patient receiving glyburide tablets, the patient should be closely observed for loss of control. When such drugs are withdrawn from a patient receiving glyburide tablets, the patient should be observed closely for hypoglycemia.

A possible interaction between glyburide and ciprofloxacin, a fluoroquinolone antibiotic, has been reported, resulting in a potentiation of the hypoglycemic action of glyburide. The mechanism for this interaction is not known.

A potential interaction between oral miconazole and oral hypoglycemic agents leading to severe hypoglycemia has been reported. Whether this interaction also occurs with the intravenous, topical or vaginal preparations of miconazole is not known.
