Description
DESCRIPTION Neomycin Sulfate Tablets, USP, for oral administration, contain neomycin which is an antibiotic obtained from the metabolic products of the actinomycete Streptomyces fradiae . Structurally, Neomycin Sulfate may be represented as follows: Chemically, it is O -2,6-diamino-2,6-dideoxy-α-D-glucopyranosyl-(1→ 3)- O -β-D-ribofuranosyl-(1→5)- O -[2,6-diamino-2, 6-dideoxy-α-D-glucopyranosyl-(1→4)]-2-deoxy-D-streptamine. Neomycin B is identical except that the α-D-glucopyranosyl residue in the neobiosamine moiety is β-L-idopyranosyl. Each tablet contains 500 mg Neomycin Sulfate (equivalent to 350 mg neomycin base). Inactive Ingredients : Calcium Stearate, Colloidal Silicon Dioxide, Povidone. Chemical Structure
How Supplied

Indications & Usage
INDICATIONS AND USAGE To reduce the development of drug-resistant bacteria and maintain the effectiveness of Neomycin Sulfate Tablets USP and other antibacterial drugs, Neomycin Sulfate Tablets USP 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: 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 Section). Hepatic Coma (Portal-Systemic Encephalopathy): 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.
Dosage and Administration
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 Neomycin Sulfate Tablets USP in doses of 4 to 12 grams of 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, 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, 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 neomycin in the tissues. Preoperative Prophylaxis for Elective Colorectal Surgery Listed below is an example of a recommended bowel preparation regimen. A proposed surgery time of 8:00 a.m. has been used. Pre-op day 3: Minimum residue or clear liquid diet. Bisacodyl, 1 tablet orally at 6:00 p.m. Pre-op day 2 : Minimum residue or clear liquid diet. Magnesium sulfate, 30 mL, 50% solution (15 g) orally at 10:00 a.m., 2:00 p.m., and 6:00 p.m. Enema at 7:00 p.m. and 8:00 p.m. Pre-op day 1 : Clear liquid diet. Supplemental (IV) fluids as needed. Magnesium sulfate, 30 mL, 50% solution (15 g) orally at 10:00 a.m., and 2:00 p.m. Neomycin sulfate (1 g) and erythromycin base (1 g) orally at 1:00 p.m., 2:00 p.m., and 11:00 p.m. No enema. Day of Operation: Patient evacuates rectum at 6:30 a.m. for scheduled operation at 8:00 a.m.
