【禁忌】
对阿米卡星过敏的病史是其使用的禁忌症。 由于已知患者对该类药物的交叉敏感性，对氨基糖甙类药物过敏或严重毒性反应的病史可能禁止使用任何其他氨基糖苷类药物。
【Therapeutic indications】
Amikacin Sulfate Injection is indicated in the short-term treatment of serious infections due to
susceptible strains of Gram-negative bacteria, including Pseudomonas species, Escherichia coli, species
of indole-positive and indole-negative Proteus, Providencia species, Klebsiella-Enterobacter-Serratia
species, and Acinetobacter (Mima-Herellea) species.
Clinical studies have shown Amikacin Sulfate Injection to be effective in bacterial septicemia (including neonatal sepsis); in serious infections of the respiratory tract, bones and joints, central nervous system (including meningitis) and skin and soft tissue; intra-abdominal infections (including peritonitis); and in burns and post-operative infections (including post-vascular surgery). Clinical studies have shown amikacin also to be effective in serious complicated and recurrent urinary tract infections due to these organisms. Aminoglycosides, including Amikacin Sulfate Injection are not indicated in uncomplicated initial episodes of urinary tract infections unless the causative organisms are not susceptible to antibiotics having less potential toxicity.
Bacteriologic studies should be performed to identify causative organisms and their susceptibilities to amikacin. Amikacin may be considered as initial therapy in suspected Gram-negative infections and therapy may be instituted before obtaining the results of susceptibility testing. Clinical trials demonstrated that amikacin was effective in infections caused by gentamicin- and/or tobramycin-resistant strains of Gram-negative organisms, particularly Proteus rettgeri, Providencia stuartii, Serratia marcescens, and Pseudomonas aeruginosa. The decision to continue therapy with the drug should be based on results of the susceptibility tests, the severity of the infection, the response of the patient and
the important additional considerations contained in the WARNINGS box above.
Amikacin has also been shown to be effective in staphylococcal infections and may be considered as initial therapy under certain conditions in the treatment of known or suspected staphylococcal disease such as, severe infections where the causative organism may be either a Gram-negative bacterium or a staphylococcus, infections due to susceptible strains of staphylococci in patients allergic to other antibiotics, and in mixed staphylococci/Gram-negative infections.
In certain severe infections such as neonatal sepsis, concomitant therapy with a penicillin-type drug may be indicated because of the possibility of infections due to Gram-positive organisms such as streptococci or pneumococci.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of amikacin and other antibacterial drugs, amikacin 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.
【CONTRAINDICATIONS】
A history of hypersensitivity to amikacin is a contraindication for its use. A history of hypersensitivity or serious toxic reactions to aminoglycosides may contraindicate the use of any other aminoglycoside because of the known cross-sensitivities of patients to drugs in this class.
【DOSAGE AND ADMINISTRATION】
The patient’s pretreatment body weight should be obtained for calculation of correct dosage. Amikacin Sulfate Injection may be given intramuscularly or intravenously.
The status of renal function should be estimated by measurement of the serum creatinine concentration or calculation of the endogenous creatinine clearance rate. The blood urea nitrogen (BUN) is much less reliable for this purpose. Reassessment of renal function should be made periodically during therapy.
Whenever possible, amikacin concentrations in serum should be measured to assure adequate but not excessive levels. It is desirable to measure both peak and trough serum concentrations intermittently during therapy. Peak concentrations (30 to 90 minutes after injection) above 35 micrograms per mL and trough concentrations (just prior to the next dose) above 10 micrograms per mL should be avoided.
Dosage should be adjusted as indicated.
