Part Used : น้ำจากผลActivity : EFFECTS ON PHARMACOKINETICSolvent/Active Compound : orange juiceType of experiment : humanType of animal : -Type of study : Open trialN(Total) : 15* (M/F = 8/7)N(Treatment) : 15 (M/F = 8/7)Sex : Both sexAge : >/= 18 yrs.Route : Oral administrationDose/Conc.(herb) : A single 500 mg tablet of ciprofloxacin with 12 ounces of orange juiceDuration : Blood samples were collected predose (baseline) and 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.5, 3, 4, 6, 8, 12, and 24 hours after each ciprofloxacin administration.Type of interaction : PharmacokineticsInteraction with drug : CiprofloxacinDose/Conc.(drug) : A single 500 mg tablet of ciprofloxacinResult : PositiveRemark : Result: When ciprofloxacin was taken with nonfortified orange juice, the Cmax and AUC 24 of the ciprofloxacin dose decreased by 23% (p = 0.001) and 21.6% (p < 0.001), respectively, as compared to when it was taken with water.Note : Although ciprofloxacin is marginally bioequivalent when administered with orange juice, it is not when it is administered with calcium-fortified orange juice. The changes in Cmax and AUC have the potential to significantly decrease clinical efficacy and promote antibiotic resistance. Not warning patients about potential food-drug interactions with fortified foods may be a major unrealized and unstudied inadvertent source of clinical failures and resistance trends with fluoroquinolones. Subject total: Subjects were healthy volunteers.
