Cefpodoxime proxetil 화학적 특성, 용도, 생산

개요
Cefpodoxime proxetil is an orally active, broad-spectrum cephalosporin especially useful in the treatment of bacterial infections in children. It is a prodrug converted by esterases in the GI walls to cefpodoxime, which reportedly has a bacteriostatic spectrum comparable to injectable third-generation cephem antibiotics.
화학적 성질
Pale Yellow Solid
용도
A broad spectrum antibiotic. Cefpodoxime proxetil is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against gram positive and gram negative microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options for infected patients. Product is to be used for research and development only.
정의
ChEBI: The 1-[(isopropoxycarbonyl)oxy]ethyl (proxetil) ester prodrug of cefpodoxime. After swallowing, hydrolysis of the ester group occurs in the intestinal epithelium, to release active cefpodoxime in the bloodstream. It is used to treat acute otitis media, pha yngitis, and sinusitis.
Clinical Use
Cefpodoxime proxetil (Vantin) is the isopropyloxycarbonylethylester of the third-generation cephalosporincefpodoxime. This orally active prodrug derivative is hydrolyzedby esterases in the intestinal wall and in theplasma to provide cefpodoxime. Tablets and a powder forthe preparation of an aqueous suspension for oral pediatricadministration are available. The oral bioavailability of cefpodoximefrom the proxetil is estimated to be about 50%.Administration of the prodrug with food enhances its absorption.The plasma half-life is 2.2 hours, which permitsadministration on a twice-daily schedule.
Cefpodoxime is a broad-spectrum cephalosporin withuseful activity against a relatively wide range of Grampositiveand Gram-negative bacteria. It is also resistant tomany β-lactamases. Its spectrum of activity includes S.pneumoniae, Streptococcus pyogenes, S. aureus, H. influenzae,M. catarrhalis, and Neisseria spp. Cefpodoxime is alsoactive against members of the Enterobacteriaceae family,including E. coli, K. pneumoniae, and P. mirabilis. It thusfinds use in the treatment of upper and lower respiratory infections,such as pharyngitis, bronchitis, otitis media, andcommunity-acquired pneumonia. It is also useful for thetreatment of uncomplicated gonorrhea.
부작용
Common side effects of Cefpodoxime proxetil include: headache, nausea, vomiting, diarrhoea, stomach pain, insomnia, vaginal swelling, redness, irritation, burning or itching. Severe may include: rash, itching, measles, difficulty breathing or swallowing, fever, sore throat, chills, or other signs of an infection coming back; swollen ankles or feet, dark urine, yellowing of the skin, easy bruising or bleeding, kidney problems. Seek medical attention if you have a serious adverse reaction.
