セファドロキシル水和物 化学特性,用途語,生産方法

• 効能

  抗生物質, 細胞壁合成阻害薬

• 説明

  Cefadroxil has an amoxicillin-like side chain at C-7 and is orally active. There are some indications that cefadroxil has some immunostimulant properties mediated through T-cell activation and that this is of material assistance to patients in fighting infections. The prolonged biological half-life of cefadroxil allows once-a-day dosage.

• 化学的特性

  White Crystalline Solid. Soluble in chloroform, miscible with ethanol and ether, insoluble in water, and will change color when exposed to light or for a long time.

• 使用

  Cefadroxil Monohydrate is a semi-synthetic cephalosporin antibacterial. It has been used for various community-acquired infections for which oral cephalosporins are appropriate.

• 定義

  ChEBI: The hydrate that is the monohydrate of the cephalosporin cefadroxil.

• 抗菌性

  Resembles closely that of cefalexin

• 一般的な説明

  Cefadroxil is a semisynthetic first-generation β-lactam cephalosporin antibiotic derived from cefalexin with antibacterial activity. It is used to treat urinary tract infections, skin and skin structure infections, pharyngitis, and tonsillitis caused by susceptible bacteria.

• 主な応用

  Cefadroxil was found by Bristol-Myers Co. in 1976. A hydroxyl group was attached to the benzene ring of cephalexin. Like amoxicillin and ampicillin, cefadroxil shows almost the same antibacterial activity spectrum as cephalexin and superior oral absorption. Its in vivo activity is four to six times greater than that of cephalexin, and its half-life in serum is twice as long.

• 薬物動態学

  Oral absorption: >90%
  C_{max 250 mg oral: c. 9 mg/L after 1.2 h
  500 mg oral: c. 18 mg/L after 1.2 h
  Plasma half-life: 1–1.5 h
  Plasma protein binding : 20%
  Absorption is little affected by administration with food. Distribution is similar to that of cefalexin. It is eliminated unchanged by glomerular filtration and tubular secretion; 90% of the dose appears in the urine over 24 h, most in the first 6 h, producing concentrations exceeding 500 mg/L.}

• 薬理学

  Cefadroxil has a broad spectrum of antimicrobial action; it is active with respect to Grampositive and Gram-negative microorganisms. Like all of the other drugs described above, it acts as a bactericide by disrupting the process of restoring the membranes of bacteria. Synonyms of this drug are bidocef, cefadril, duracef, ultracef, and others.

• 臨床応用

  Cefadroxil (Duricef) is an orally active semisyntheticderivative of 7-ADCA, in which the 7-acyl group is the Dhydroxylphenylglycylmoiety. This compound is absorbedwell after oral administration to give plasma levels that reach75% to 80% of those of an equal dose of its close structuralanalog cephalexin. The main advantage claimed for cefadroxilis its somewhat prolonged duration of action, whichpermits once-a-day dosing. The prolonged duration of actionof this compound is related to relatively slow urinary excretionof the drug compared with other cephalosporins, butthe basis for this remains to be explained completely. Theantibacterial spectrum of action and therapeutic indications ofcefadroxil are very similar to those of cephalexin and cephradine.The D-p-hydroxyphenylglycyl isomer is much moreactive than the L-isomer.

• 副作用

  Side effects described are those common to oral cephalosporins.
