Линкомицина гидрохлорид-Виал

Линкомицина гидрохлорид-Виалмицина гидрохлорид-ВиалCIN Sterile Solution is indicated in the treatment of serious infections due to susceptible strains of streptococci, pneumococci, and staphylococci. Its use should be reserved for penicillin-allergic patients or other patients for whom, in the judgment of the physician, a penicillin is inappropriate. Because of the risk of antibacterial associated pseudomembranous colitis, as described in the WARNING box, before selecting Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin the physician should consider the nature of the infection and the suitability of less toxic alternatives (e.g., erythromycin).

Indicated surgical procedures should be performed in conjunction with antibacterial therapy.

The drug may be administered concomitantly with other antimicrobial agents when indicated.

Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin is not indicated in the treatment of minor bacterial infections or viral infections.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Линкомицина гидрохлорид-Виалмицина гидрохлорид-ВиалCIN and other antibacterial drugs, Линкомицина гидрохлорид-Виалмицина гидрохлорид-ВиалCIN 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.

If significant diarrhea occurs during therapy, this antibacterial should be discontinued. (see BOX WARNING.)

Intramuscular

Adults

Serious infections—600 mg (2 mL) intramuscularly every 24 hours. More severe infections—600 mg (2 mL) intramuscularly every 12 hours or more often.

Pediatric Patients Over 1 Month Of Age

Serious infections—one intramuscular injection of 10 mg/kg (5 mg/lb) every 24 hours. More severe infections—one intramuscular injection of 10 mg/kg (5 mg/lb) every 12 hours or more often.

Intravenous

Adults

The intravenous dose will be determined by the severity of the infection. For serious infections doses of 600 mg of Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin (2 mL of Линкомицина гидрохлорид-Виалмицина гидрохлорид-ВиалCIN) to 1 gram are given every 8 to 12 hours. For more severe infections these doses may have to be increased. In life-threatening situations daily intravenous doses of as much as 8 grams have been given. Intravenous doses are given on the basis of 1 gram of Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin diluted in not less than 100 mL of appropriate solution (see Physical Compatibities) and infused over a period of not less than one hour.

These doses may be repeated as often as required to the limit of the maximum recommended daily dose of 8 grams of Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin.

Pediatric Patients Over 1 Month Of Age

10 to 20 mg/kg/day (5 to 10 mg/lb/day) depending on the severity of the infection may be infused in divided doses as described above for adults.

Reported with intramuscular injection.

NOTE: Severe cardiopulmonary reactions have occurred when this drug has been given at greater than the recommended concentration and rate.

Subconjunctival Injection

0.25 mL (75 mg) injected subconjunctivally will result in ocular fluid levels of antibacterial (lasting for at least 5 hours) with MICs sufficient for most susceptible pathogens.

WARNINGS

Clostridium Difficile Associated Diarrhea

Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.

C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.

If CDAD is suspected or confirmed, ongoing antibacterial use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.

Hypersensitivity

Serious hypersensitivity reactions, including anaphylaxis and erythema multiforme, have been reported with use of Линкомицина гидрохлорид-Виалмицина гидрохлорид-ВиалCIN. If an allergic reaction to Линкомицина гидрохлорид-Виалмицина гидрохлорид-ВиалCIN occurs, discontinue the drug. (see ADVERSE REACTIONS)

Benzyl Alcohol Toxicity In Pediatric Patients (Gasping Syndrome)

This product contains benzyl alcohol as a preservative.

The preservative benzyl alcohol has been associated with serious adverse events, including the "gasping syndrome", and death in pediatric patients. Although normal therapeutic doses of this product ordinarily deliver amounts of benzyl alcohol that are substantially lower than those reported in association with the "gasping syndrome", the minimum amount of benzyl alcohol at which toxicity may occur is not known. The risk of benzyl alcohol toxicity depends on the quantity administered and the liver and kidneys' capacity to detoxify the chemical. Premature and low-birth weight infants may be more likely to develop toxicity.

Use in Meningitis — Although Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin appears to diffuse into cerebrospinal fluid, levels of Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin in the CSF may be inadequate for the treatment of meningitis.

PRECAUTIONS

General

Review of experience to date suggests that a subgroup of older patients with associated severe illness may tolerate diarrhea less well. When Линкомицина гидрохлорид-Виалмицина гидрохлорид-ВиалCIN is indicated in these patients, they should be carefully monitored for change in bowel frequency.

Линкомицина гидрохлорид-Виалмицина гидрохлорид-ВиалCIN should be prescribed with caution in individuals with a history of gastrointestinal disease, particularly colitis.

Линкомицина гидрохлорид-Виалмицина гидрохлорид-ВиалCIN should be used with caution in patients with a history of asthma or significant allergies.

Certain infections may require incision and drainage or other indicated surgical procedures in addition to antibacterial therapy.

The use of Линкомицина гидрохлорид-Виалмицина гидрохлорид-ВиалCIN may result in overgrowth of nonsusceptible organisms— particularly yeasts. Should superinfections occur, appropriate measures should be taken as indicated by the clinical situation. When patients with pre-existing monilial infections require therapy with Линкомицина гидрохлорид-Виалмицина гидрохлорид-ВиалCIN, concomitant antimonilial treatment should be given.

The serum half-life of Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin may be prolonged in patients with severe impairment of renal function compared to patients with normal renal function. In patients with abnormal hepatic function, serum half-life may be twofold longer than in patients with normal hepatic function.

Patients with severe impairment of renal function and/or abnormal hepatic function should be dosed with caution and serum Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin levels monitored during high-dose therapy. (see DOSAGE AND ADMINISTRATION)

Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin should not be injected intravenously undiluted as a bolus, but should be infused over at least 60 minutes as directed in the DOSAGE AND ADMINISTRATIONSection.

Prescribing Линкомицина гидрохлорид-Виалмицина гидрохлорид-ВиалCIN 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.

Laboratory Tests

During prolonged therapy with Линкомицина гидрохлорид-Виалмицина гидрохлорид-ВиалCIN, periodic liver and kidney function tests and blood counts should be performed.

Carcinogenesis, Mutagenesis, Impairment Of Fertility

The carcinogenic potential of Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin has not been evaluated.

Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin was not found to be mutagenic in the Ames Salmonella reversion assay or the V79 Chinese hamster lung cells at the HGPRT locus. It did not induce DNA strand breaks in V79 Chinese hamster lung cells as measured by alkaline elution or chromosomal abnormalities in cultured human lymphocytes. In vivo, Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin was negative in both the rat and mouse micronucleus assays and it did not induce sex-linked recessive lethal mutations in the offspring of male Drosophila. However, Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin did cause unscheduled DNA syntheses in freshly isolated rat hepatocytes.

Impairment of fertility was not observed in male or female rats given oral 300 mg/kg doses of Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin (0.36 times the highest recommended human dose based on mg/m² ).

Pregnancy

Pregnancy Category C

Линкомицина гидрохлорид-Виалмицина гидрохлорид-ВиалCIN Sterile Solution contains benzyl alcohol as a preservative. Benzyl alcohol can cross the placenta. See WARNINGS.

Teratogenic Effects

There are no studies on the teratogenic potential of Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin in animals or adequate and wellcontrolled studies of pregnant women.

Nonteratogenic Effects

Reproduction studies have been performed in rats using oral doses of Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin up to 1000 mg/kg (1.2 times the maximum daily human dose based on mg/m² ) and have revealed no adverse effects on survival of offspring from birth to weaning.

Nursing Mothers

Линкомицина гидрохлорид-Виалмицина гидрохлорид-Виалmycin has been reported to appear in human milk in concentrations of 0.5 to 2.4 μg/mL. Because of the potential for serious adverse reactions in nursing infants from Линкомицина гидрохлорид-Виалмицина гидрохлорид-ВиалCIN, 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
