Streptomicin Sulfat Galenika

Streptomicin Sulfat Galenika is indicated for the treatment of individuals with moderate to severe infections caused by susceptible strains of microorganisms in the specific conditions listed below:

1. Mycobacterium tuberculosis: The Advisory Council for the Elimination of Tuberculosis, the American Thoracic Society, and the Center for Disease Control recommend that either Streptomicin Sulfat Galenika or ethambutol be added as a fourth drug in a regimen containing isoniazid (INH), rifampin and pyrazinamide for initial treatment of tuberculosis unless the likelihood of INH or rifampin resistance is very low. The need for a fourth drug should be reassessed when the results of susceptibility testing are known. In the past when the national rate of primary drug resistance to isoniazid was known to be less than 4% and was either stable or declining, therapy with two and three drug regimens was considered adequate. If community rates of INH resistance are currently less than 4%, an initial treatment regimen with less than four drugs may be considered.

Streptomicin Sulfat Galenika is also indicated for therapy of tuberculosis when one or more of the above drugs is contraindicated because of toxicity or intolerance. The management of tuberculosis has become more complex as a consequence of increasing rates of drug resistance and concomitant HIV infection. Additional consultation from experts in the treatment of tuberculosis may be desirable in those settings.

2. Non-tuberculosis infections: The use of Streptomicin Sulfat Galenika should be limited to the treatment of infections caused by bacteria which have been shown to be susceptible to the antibacterial effects of Streptomicin Sulfat Galenika and which are not amenable to therapy with less potentially toxic agents.

1. Pasteurella pestis (plague),
2. Francisella tularensis (tularemia),
3. Brucella,
4. Calymmatobacterium granulomatis (donovanosis, granuloma inguinale),
5. H. ducreyi (chancroid),
6. H. influenzae (in respiratory, endocardial, and meningeal infections - concomitantly with another antibacterial agent),
7. K. pneumoniae pneumonia (concomitantly with another antibacterial agent),
8. E.coli, Proteus, A. aerogenes, K. pneumoniae, and Enterococcus faecalis in urinary tract infections,
9. Streptococcus viridans, Enterococcus faecalis (in endocardial infections - concomitantly with penicillin),
10. Gram-negative bacillary bacteremia (concomitantly with another antibacterial agent).

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Streptomicin Sulfat Galenika and other antibacterial drugs, Streptomicin Sulfat Galenika 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.

Intramuscular Route Only

Adults: The preferred site is the upper outer quadrant of the buttock, (i.e., gluteus maximus), or the mid-lateral thigh.

Children: It is recommended that intramuscular injections be given preferably in the mid-lateral muscles of the thigh. In infants and small children the periphery of the upper outer quadrant of the gluteal region should be used only when necessary, such as in burn patients, in order to minimize the possibility of damage to the sciatic nerve.

The deltoid area should be used only if well developed such as in certain adults and older children, and then only with caution to avoid radial nerve injury. Intramuscular injections should not be made into the lower and mid-third of the upper arm. As with all intramuscular injections, aspiration is necessary to help avoid inadvertent injection into a blood vessel.

Injection sites should be alternated. As higher doses or more prolonged therapy with Streptomicin Sulfat Galenika may be indicated for more severe or fulminating infections (endocarditis, meningitis, etc.), the physician should always take adequate measures to be immediately aware of any toxic signs or symptoms occurring in the patient as a result of Streptomicin Sulfat Galenika therapy.

1. TUBERCULOSIS: The standard regimen for the treatment of drug susceptible tuberculosis has been two months of INH, rifampin and pyrazinamide followed by four months of INH and rifampin (patients with concomitant infection with tuberculosis and HIV may require treatment for a longer period).When Streptomicin Sulfat Galenika is added to this regimen because of suspected or proven drug resistance (see INDICATIONS AND USAGE section), the recommended dosing for Streptomicin Sulfat Galenika is as follows:

Streptomicin Sulfat Galenika is usually administered daily as a single intramuscular injection. A total dose of not more than 120 g over the course of therapy should be given unless there are no other therapeutic options. In patients older than 60 years of age the drug should be used at a reduced dosage due to the risk of increased toxicity. (See BOXED WARNING.)

Therapy with Streptomicin Sulfat Galenika may be terminated when toxic symptoms have appeared, when impending toxicity is feared, when organisms become resistant, or when full treatment effect has been obtained. The total period of drug treatment of tuberculosis is a minimum of 1 year; however, indications for terminating therapy with Streptomicin Sulfat Galenika may occur at any time as noted above.

2. TULAREMIA: One to 2 g daily in divided doses for 7 to 14 days until the patient is afebrile for 5 to 7 days.

3. PLAGUE: Two grams of Streptomicin Sulfat Galenika daily in two divided doses should be administered intramuscularly. A minimum of 10 days of therapy is recommended.

4. BACTERIAL ENDOCARDITIS:

1. Streptococcal endocarditis; in penicillin-sensitive alpha and non-hemolytic streptococcal endocarditis (penicillin MIC ≤0.1 mcg/mL), Streptomicin Sulfat Galenika may be used for 2-week treatment concomitantly with penicillin. The Streptomicin Sulfat Galenika regimen is 1 g b.i.d. for the first week, and 500 mg b.i.d. for the second week. If the patient is over 60 years of age, the dosage should be 500 mg b.i.d. for the entire 2-week period.
2. Enterococcal endocarditis: Streptomicin Sulfat Galenika in doses of 1 g b.i.d. for 2 weeks and 500 mg b.i.d. for an additional 4 weeks is given in combination with penicillin. Ototoxicity may require termination of the Streptomicin Sulfat Galenika prior to completion of the 6-week course of treatment.

5. CONCOMITANT USE WITH OTHER AGENTS: For concomitant use with other agents to which the infecting organism is also sensitive: Streptomicin Sulfat Galenika is considered a second-line agent for the treatment of gram-negative bacillary bacteremia, meningitis, and pneumonia; brucellosis; granuloma inguinale; chancroid, and urinary tract infection.

For adults: 1 to 2 grams in divided doses every six to twelve hours for moderate to severe infections. Doses should generally not exceed 2 grams per day.

For children: 20 to 40 mg/kg/day (8 to 20 mg/lb/day) in divided doses every 6 to 12 hours. (Particular care should be taken to avoid excessive dosage in children.)

The dry lyophillized cake is dissolved by adding Water for Injection USP in an amount to yield the desired concentration as indicated in the following table:

Sterile reconstituted solutions should be protected from light and may be stored at room temperature for one week without significant loss of potency.

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

A history of clinically significant hypersensitivity to Streptomicin Sulfat Galenika is a contraindication to its use. Clinically significant hypersensitivity to other aminoglycosides may contraindicate the use of Streptomicin Sulfat Galenika because of the known cross-sensitivity of patients to drugs in this class.

WARNINGS

Ototoxicity: Both vestibular and auditory dysfunction can follow the administration of Streptomicin Sulfat Galenika. The degree of impairment is directly proportional to the dose and duration of Streptomicin Sulfat Galenika administration, to the age of the patient, to the level of renal function and to the amount of underlying existing auditory dysfunction. The ototoxic effects of the aminoglycosides, including Streptomicin Sulfat Galenika, are potentiated by the co-administration of ethacrynic acid, mannitol, furosemide and possibly other diuretics.

The vestibulotoxic potential of Streptomicin Sulfat Galenika exceeds that of its capacity for cochlear toxicity. Vestibular damage is heralded by headache, nausea, vomiting and disequilibrium. Early cochlear injury is demonstrated by the loss of high frequency hearing. Appropriate monitoring and early discontinuation of the drug may permit recovery prior to irreversible damage to the sensorineural cells.

Pregnancy: Streptomicin Sulfat Galenika can cause fetal harm when administered to a pregnant woman. Because Streptomicin Sulfat Galenika readily crosses the placental barrier, caution in use of the drug is important to prevent ototoxicity in the fetus. If this drug 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 Streptomicin Sulfat Galenika 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.

Baseline and periodic caloric stimulation tests and audiometric tests are advisable with extended Streptomicin Sulfat Galenika therapy. Tinnitus, roaring noises, or a sense of fullness in the ears indicates need for audiometric examination or termination of Streptomicin Sulfat Galenika therapy or both.

Care should be taken by individuals handling Streptomicin Sulfat Galenika for Injection to avoid skin sensitivity reactions. As with all intramuscular preparations, Streptomicin Sulfat Galenika for Injection should be injected well within the body of a relatively large muscle and care should be taken to minimize the possibility of damage to peripheral nerves. (See DOSAGE AND ADMINISTRATION.)

Extreme caution must be exercised in selecting a dosage regimen in the presence of preexisting renal insufficiency. In severely uremic patients a single dose may produce high blood levels for several days and the cumulative effect may produce ototoxic sequelae. When Streptomicin Sulfat Galenika must be given for prolonged periods of time alkalinization of the urine may minimize or prevent renal irritation.

A syndrome of apparent central nervous system depression, characterized by stupor and flaccidity, occasionally coma and deep respiratory depression, has been reported in very young infants in whom Streptomicin Sulfat Galenika dosage had exceeded the recommended limits. Thus, infants should not receive Streptomicin Sulfat Galenika in excess of the recommended dosage.

In the treatment of venereal infections such as granuloma inguinale, and chancroid, if concomitant syphilis is suspected, suitable laboratory procedures such as a dark field examination should be performed before the start of treatment, and monthly serologic tests should be done for at least four months.

As with other antibiotics, use of this drug may result in overgrowth of nonsusceptible organisms, including fungi. If superinfection occurs, appropriate therapy should be instituted.

Pregnancy: Category D: See WARNINGS section.

Nursing Mothers: Because of the potential for serious adverse reactions in nursing infants from Streptomicin Sulfat Galenika, 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: (See DOSAGE AND ADMINISTRATION.)

The following reactions are common: vestibular ototoxicity (nausea, vomiting, and vertigo); paresthesia of face; rash; fever; urticaria; angioneurotic edema; and eosinophilia.

The following reactions are less frequent: cochlear ototoxicity (deafness); exfoliative dermatitis; anaphylaxis; azotemia; leucopenia; thrombocytopenia; pancytopenia; hemolytic anemia; muscular weakness; and amblyopia.

Vestibular dysfunction resulting from the parenteral administration of Streptomicin Sulfat Galenika is cumulatively related to the total daily dose. When 1.8 to 2 g/day are given, symptoms are likely to develop in the large percentage of patients - especially in the elderly or patients with impaired renal function - within four weeks. Therefore, it is recommended that caloric and audiometric tests be done prior to, during, and following intensive therapy with Streptomicin Sulfat Galenika in order to facilitate detection of any vestibular dysfunction and/or impairment of hearing which may occur.

Vestibular symptoms generally appear early and usually are reversible with early detection and cessation of Streptomicin Sulfat Galenika administration. Two to three months after stopping the drug, gross vestibular symptoms usually disappear, except from the relative inability to walk in total darkness or on very rough terrain.

Although Streptomicin Sulfat Galenika is the least nephrotoxic of the aminoglycosides, nephrotoxicity does occur rarely.

Clinical judgment as to termination of therapy must be exercised when side effects occur.
