Imipenem C화학적 특성, 용도, 생산
개요
Imipenem is a chemically stable thienamycin derivative with an antibacterial activity that is broader in spectrum and of greater potency than most of the third generation cephalosporins. Combination with cilastatin, an inhibitor of renal brush-border dehydropeptidase-I, increases both urinary and plasma levels of imipenem.화학적 성질
White Crystals용도
Carbapenem antibacterial.Antimicrobial activity
Imipenem shows potent activity against a wide range of Grampositive and Gram-negative aerobes and anaerobes, including many resistant to other agents.Concentrations (mg/L) inhibiting 50% of strains of other organisms are: Listeria monocytogenes, 0.03; Legionella pneumophila, 0.03; Enterococcus faecium, 4; Yersinia spp., 0.06. Mycobacterium fortuitum is inhibited by 6.25 mg/L. Imipenem is active against many Pseudomonas species, but not Sten. maltophilia. It is active against most anaerobes, with the exception of Cl. perfringens, which is only moderately susceptible. It is bactericidal at 2–4 times the MIC for most species, but some strains of Staph. aureus exhibit ‘tolerance’ . Bactericidal synergy with aminoglycosides, glycopeptides, fosfomycin and rifampicin (rifampin) has been observed against many strains of Staph. aureus and enterococci.Antibacterial activity is unaffected by the presence of cilastatin, which is itself devoid of antimicrobial activity.
Imipenem is stable to hydrolysis by most serine β-lactamases, with the exception of the group 2f carbapenem-hydrolyzingenzymes hydrolyzingenzymes . Strains of B. fragilis, Aeromonas spp. and Sten. maltophilia can produce metallo-β-lactamases that hydrolyze the drug rapidly. These strains, in addition to occasional strains of enterobacteria, Acinetobacter baumannii and Ps. aeruginosa, show variable resistance to imipenem depending upon the level of carbapenem-hydrolyzing enzymes and the presence or absence of imipenem-specific porins. Efflux pumps also exist that may extrude imipenem from Gramnegative bacteria.
원료
Some strains of Citrobacter, Enterobacter, Proteus vulgaris, Providencia, Ps. aeruginosa and Serratia spp. may be resistant to imipenem and other β-lactam agents, often because of the selection of stably derepressed mutants expressing high levels of group 1 β-lactamases coupled with decreased intracellular drug levels due to porin mutations or increased efflux.Induction of class 1 β-lactamases by imipenem in strains of Aeromonas, Pseudomonas and Serratia spp. is responsible for antagonism of β-lactamase-labile β-lactam agents in vitro. Imipenem resistance in Ps. aeruginosa can occur following selection of mutants that hyperproduce the group 1 cephalosporinase and which are also deficient in an outer membrane protein (OprD or D2) which specifically transports imipenem, but not cephalosporins or monobactams.
일반 설명
Thienamycin was found in the culture broth of Streptomyces cattleya by Merck Sharp & Dohme in 1976, as a very unstable substance. It has a unique carbapenem structure, like that of the olivanic acids found in S. olivaceus by Beecham Research Laboratories in 1979. Thienamycin shows excellent activity against a variety of pathogenic bacteria, including Pseudomonas aeruginosa. Its chemical stability has been improved by derivatization with the formimidoyl group, and its biological stability has been improved by combining it with cilastatin, an inhibitor of kidney dihydropeptidase. The combination drug imipenem – cilastatin is now under study to evaluate its clinical efficacy and safety.Clinical Use
Lower respiratory tract infectionsUrinary tract infections (complicated and uncomplicated)

Gynecological infections
Bacterial septicemia

Endocarditis
Polymicrobial infections
부작용
CNS effects such as confusional states and seizures have been reported, especially when recommended doses were exceeded, and in patients with renal failure or creatinine clearances of ≤20 mL/min/1.73 m2.Other reactions include phlebitis/thrombophlebitis (3.1%), nausea (2.0%), diarrhea (1.8%) and vomiting (1.5%).
Increased hepatic enzymes may be seen in adults and children. Superinfection with Aspergillus, Candida and resistant Pseudomonas spp. have been described and pseudomembranous colitis has been reported.
Patients with a history of hypersensitivity reactions to penicillins, cephalosporins or other β-lactam antibiotics should be treated cautiously with carbapenems.
