Description
Curator's Comment: The description was created based on several sources, including http://www.accessdata.fda.gov/drugsatfda_docs/nda/98/20-695S003_Raxar_Prntlbl.pdf | https://www.ncbi.nlm.nih.gov/pubmed/9454812

Grepafloxacin, (R)- is an asymmetric fluoroquinolone derivative which possesses high tissue penetrability as well as strong, broad-spectrum antimicrobial activities. Grepafloxacin has a chiral center and therefore has two optical enantiomeric isomers, R(+)- and S(-)-grepafloxacin. In neutrophil respiratory burst induced by N-formyl-methionyl leucyl-phenylalanine grepafloxacin induces a priming effect. The R(+) enantiomer of grepafloxacin induced a more potent priming effect than did S(-)-grepafloxacin. R(+)-Grepafloxacin also produced a more potent translocation of both p47- and p67-phox proteins to membrane fractions of neutrophils. Grepafloxacin-induced primed superoxide generation was significantly inhibited by pretreatment with PD169316 and SB203580, p38 mitogen-activated protein kinase (MAPK) inhibitors, but not with PD98059, a specific inhibitor of the upstream kinase that activates p44/42 MAPK, or SP600125, an inhibitor of stress-activated protein kinase/c-Jun N-terminal kinase (JNK).

Sample Use Guides

RAXAR (R/S-Grepafloxacin) Tablets may be taken with or without meals. The usual dose for RAXAR is 400 mg or 600 mg orally every 24 hours. Sucralfate; antacids containing magnesium, calcium, or aluminum; multivitamins containing iron or zinc; or VIDEX (didanosine) chewable/buffered tablets or the pediatric powder for oral solution should not be taken within 4 hours before or 4 hours after taking grepafloxacin.
Route of Administration: Oral
In Vitro Use Guide
The activity of R/S-grepafloxacin was evaluated against five isolates of Chlamydia pneumonia and 21 isolates of Chlamydia trachomatis. MICs were determined using a tissue culture incorporation technique in McCoy cell monolayers treated with Grepafloxacin. After 48–72 h incubation, cover slips were fixed in methanol and stained with an immunofluorescent monoclonal antibody against the major outer membrane protein. Grepafloxacin MIC range was 0.06–0.12 mg/L.
