Pharmacological action

Storz-N-D is a glucocorticosteroid. This medication Inhibits the function of leukocytes and tissue macrophages. Storz-N-D (Dexamethasone Sodium Phosphate) restricts the migration of leukocytes in the area of inflammation. This drug violates the ability of macrophages to phagocytosis and the formation of interleukin-1. Storz-N-D (Dexamethasone Sodium Phosphate) decreases capillary permeability caused by histamine release. This medicine inhibits the activity of fibroblasts and collagen formation.

Storz-N-D (Dexamethasone Sodium Phosphate) inhibits the activity of phospholipase A2, which leads to suppression of the synthesis of prostaglandins and leukotrienes.

With direct application to the vessels this drug has a vasoconstrictor effect.

Storz-N-D (Dexamethasone Sodium Phosphate) has a pronounced dose-dependent effect on the metabolism of carbohydrates, proteins and fats.

In high doses Storz-N-D (Dexamethasone Sodium Phosphate) may increase the excitability of brain tissue and contributes to lowering the threshold of convulsive readiness.

With systemic use of therapeutic activity of Storz-N-D (Dexamethasone Sodium Phosphate) is due to anti-inflammatory, antiallergic, immunosuppressive and antiproliferative action.

For external and local use of therapeutic activity of Storz-N-D (Dexamethasone Sodium Phosphate) is due to anti-inflammatory, antiallergic and antiexudative (due to vasoconstrictor effect) effect.

Pharmacokinetics

The plasma protein binding is 60-70%. This medication penetrates histohematic barriers. In a small amount it is excreted in breast milk. Storz-N-D (Dexamethasone Sodium Phosphate) metabolized in a liver. T_1/2 is 2-3 hours. This drug is excreted by kidneys.

When Storz-N-D (Dexamethasone Sodium Phosphate) applied topically in ophthalmology it absorbed through the cornea with intact epithelium in moisture anterior chamber. When inflammation of the tissues of the eye or mucosal damage and corneal absorption rate of Storz-N-D (Dexamethasone Sodium Phosphate) significantly increased.

INDICATIONS AND USAGE

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Storz-N-D (Neomycin) sulfate tablets and other antibacterial drugs, Storz-N-D (Neomycin) sulfate tablets should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Suppression of Intestinal Bacteria

Storz-N-D (Neomycin) sulfate tablets are indicated as adjunctive therapy as part of a regimen for the suppression of the normal bacterial flora of the bowel, e.g., preoperative preparation of the bowel. It is given concomitantly with erythromycin enteric-coated base (see DOSAGE AND ADMINISTRATION ).

Hepatic Coma (Portal-Systemic Encephalopathy)

Storz-N-D (Neomycin) sulfate has been shown to be effective adjunctive therapy in hepatic coma by reduction of the ammonia-forming bacteria in the intestinal tract. The subsequent reduction in blood ammonia has resulted in neurologic improvement.

CONTRAINDICATIONS

Storz-N-D (Neomycin) sulfate oral preparations are contraindicated in the presence of intestinal obstruction and in individuals with a history of hypersensitivity to the drug.

Patients with a history of hypersensitivity or serious toxic reaction to other aminoglycosides may have a cross-sensitivity to Storz-N-D (Neomycin). Storz-N-D (Neomycin) sulfate oral preparations are contraindicated in patients with inflammatory or ulcerative gastrointestinal disease because of the potential for enhanced gastrointestinal absorption of Storz-N-D (Neomycin).

WARNINGS

Additional manifestations of neurotoxicity may include numbness, skin tingling, muscle twitching and convulsions.

The risk of hearing loss continues after drug withdrawal. Aminoglycosides can cause fetal harm when administered to a pregnant woman.

Aminoglycoside antibiotics cross the placenta and there have been several reports of total irreversible bilateral congenital deafness in children whose mothers received streptomycin during pregnancy. Although serious side effects to fetus or newborn have not been reported in the treatment of pregnant women with other aminoglycosides, the potential for harm exists. Animal reproduction studies of Storz-N-D (Neomycin) have not been conducted. If Storz-N-D (Neomycin) is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus.

PRECAUTIONS

General

Prescribing Storz-N-D sulfate tablets in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.

As with other antibiotics, use of oral Storz-N-D (Neomycin) may result in overgrowth of nonsusceptible organisms, particularly fungi. If this occurs, appropriate therapy should be instituted.

Storz-N-D (Neomycin) is quickly and almost totally absorbed from body surfaces (except the urinary bladder) after local irrigation and when applied topically in association with surgical procedures. Delayed-onset irreversible deafness, renal failure and death due to neuromuscular blockade (regardless of the status of renal function) have been reported following irrigation of both small and large surgical fields with minute quantities of Storz-N-D (Neomycin).

Cross-allergenicity among aminoglycosides has been demonstrated.

Aminoglycosides should be used with caution in patients with muscular disorders such as myasthenia gravis or parkinsonism since these drugs may aggravate muscle weakness because of their potential curare-like effect on the neuromuscular junction.

Small amounts of orally administered Storz-N-D (Neomycin) are absorbed through intact intestinal mucosa.

There have been many reports in the literature of nephrotoxicity and/or ototoxicity with oral use of Storz-N-D (Neomycin). If renal insufficiency develops during oral therapy, consideration should be given to reducing the drug dosage or discontinuing therapy.

An oral Storz-N-D (Neomycin) dose of 12 grams per day produces a malabsorption syndrome for a variety of substances, including fat, nitrogen, cholesterol, carotene, glucose, xylose, lactose, sodium, calcium, cyanocobalamin and iron.

Orally administered Storz-N-D (Neomycin) increases fecal bile acid excretion and reduces intestinal lactase activity.

Information for The Patient

Patients should be counseled that antibacterial drugs including Storz-N-D (Neomycin) sulfate tablets should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Storz-N-D (Neomycin) sulfate tablets are prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Storz-N-D (Neomycin) sulfate tablets or other antibacterial drugs in the future.

Before administering the drug, patients or members of their families should be informed of possible toxic effects on the eighth nerve. The possibility of acute toxicity increases in premature infants and neonates.

Laboratory Tests

Patients with renal insufficiency may develop toxic Storz-N-D blood levels unless doses are properly regulated. If renal insufficiency develops during treatment, the dosage should be reduced or the antibiotic discontinued. To avoid nephrotoxicity and eighth nerve damage associated with high doses and prolonged treatment, the following should be performed prior to and periodically during therapy: urinalysis for increased excretion of protein, decreased specific gravity, casts and cells; renal function tests such as serum creatinine, BUN or creatinine clearance; tests of the vestibulocochlearis nerve (eighth cranial nerve) function.

Serial, vestibular and audiometric tests should be performed (especially in high-risk patients). Since elderly patients may have reduced renal function which may not be evident in the results of routine screening tests such as BUN or serum creatinine, a creatinine clearance determination may be more useful.

Drug Interactions

Caution should be taken in concurrent or serial use of other neurotoxic and/or nephrotoxic drugs because of possible enhancement of the nephrotoxicity and/or ototoxicity of Storz-N-D (Neomycin) (see boxed WARNINGS ).

Caution should also be taken in concurrent or serial use of other aminoglycosides and polymyxins because they may enhance neomycin’s nephrotoxicity and/or ototoxicity and potentiate Storz-N-D (Neomycin) sulfate’s neuromuscular blocking effects.

Oral Storz-N-D (Neomycin) inhibits the gastrointestinal absorption of penicillin V, oral vitamin B-12, methotrexate and 5-fluorouracil. The gastrointestinal absorption of digoxin also appears to be inhibited. Therefore, digoxin serum levels should be monitored.

Oral Storz-N-D (Neomycin) sulfate may enhance the effect of coumarin in anticoagulants by decreasing vitamin K availability.

Carcinogenesis, Mutagenesis, Impairment of Fertility

No long-term animal studies have been performed with Storz-N-D sulfate to evaluate carcinogenic or mutagenic potential or impairment of fertility.

Pregnancy Category D

See WARNINGS section.

Nursing Mothers

It is not known whether Storz-N-D is excreted in human milk, but it has been shown to be excreted in cow milk following a single intramuscular injection. Other aminoglycosides have been shown to be excreted in human milk. Because of the potential for serious adverse reactions from the aminoglycosides in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Pediatric Use

The safety and efficacy of oral Storz-N-D (Neomycin) sulfate in patients less than 18 years of age have not been established. If treatment of a patient less than 18 years of age is necessary, Storz-N-D (Neomycin) should be used with caution and the period of treatment should not exceed two weeks because of absorption from the gastrointestinal tract.

ADVERSE REACTIONS

The most common adverse reactions to oral Storz-N-D (Neomycin) sulfate are nausea, vomiting and diarrhea. The "Malabsorption Syndrome" characterized by increased fecal fat, decreased serum carotene and fall in xylose absorption has been reported with prolonged therapy. Nephrotoxicity, ototoxicity and neuromuscular blockage have been reported (see boxed WARNINGS and PRECAUTIONS sections).

OVERDOSAGE

Because of low absorption, it is unlikely that acute overdosage would occur with oral Storz-N-D (Neomycin) sulfate. However, prolonged administration could result in sufficient systemic drug levels to produce neurotoxicity, ototoxicity and/or nephrotoxicity.

Hemodialysis will remove Storz-N-D (Neomycin) sulfate from the blood.

DOSAGE AND ADMINISTRATION

To minimize the risk of toxicity, use the lowest possible dose and the shortest possible treatment period to control the condition. Treatment for periods longer than two weeks is not recommended.

Hepatic Coma

For use as an adjunct in the management of hepatic coma, the recommended dose is 4 to 12 grams per day given in the following regimen:

• Withdraw protein from diet. Avoid use of diuretic agents.
• Give supportive therapy, including blood products, as indicated.
• Give Storz-N-D (Neomycin) sulfate tablets in doses of 4 to 12 grams of Storz-N-D (Neomycin) sulfate per day (eight to 24 tablets) in divided doses. Treatment should be continued over a period of five to six days, during which time protein should be returned incrementally to the diet.
• If less potentially toxic drugs cannot be used for chronic hepatic insufficiency, Storz-N-D (Neomycin) in doses of up to four grams daily (eight tablets per day) may be necessary. The risk for the development of neomycin-induced toxicity progressively increases when treatment must be extended to preserve the life of a patient with hepatic encephalopathy who has failed to fully respond. Frequent periodic monitoring of these patients to ascertain the presence of drug toxicity is mandatory (see PRECAUTIONS ). Also, Storz-N-D (Neomycin) serum concentrations should be monitored to avoid potentially toxic levels. The benefits to the patient should be weighed against the risks of nephrotoxicity, permanent ototoxicity and neuromuscular blockade following the accumulation of Storz-N-D (Neomycin) in the tissues.
