Ciprofloxacin, like other new quinolones, has shown good in vitro activity against the pathogens most frequently encountered in UTI, high concentrations in the urine and is well tolerated.

2. Thirty-six women received 250 mg and forty-two received 500 mg of ciprofloxacin as a single dose.

Clinical and bacteriological cures were attained in 81% and 93% of the 250 mg and 500 mg dose groups, respectively, 7 days after treatment. Follow-up at 4 weeks after completion of treatment disclosed that the clinical cure rate was 62% and 79% respectively.

Abstract – Background: Three studies were undertaken to determine the minimum effective dosing regimen of ciprofloxacin for the treatment of acute, symptomatic, uncomplicated lower urinary tract infection. Methods: All studies were multicenter, prospective, randomized, double-blind trials.

A total of 970 evaluable patients with a diagnosis of urinary tract infection received oral ciprofloxacin (200 mg to 500 mg daily in one or two divided doses for 1, 3, 5, or 7 days) or norfloxacin (400 mg twice daily for 7 days). The primary measure of efficacy was bacteriologic eradication at the end of therapy.

Results: In study 1, bacteriologic eradication was reported in 95 (89%) and 101 (98%) of patients in the groups who received ciprofloxacin, 500-mg single dose and 250 mg BID for 7 days, respectively. Clinical success occurred in 101 patients (94%) who received a 500-mg single dose and in 103 patients (100%) who were administered 250 mg BID for 7 days.

1. In study 2, eradication rates in the groups who received ciprofloxacin, 100 mg BID for 3 days, 250 mg BID for 3 days, and 250 mg BID for 7 days, were 98 (93%), 95 (90%), and 98 (93%), respectively.
2. Clinical success was reported in 102 (97%), 105 (100%), and 104 (98%) of the patients, respectively.
3. In study 3, the eradication rates in the groups who received ciprofloxacin in dosages of 500 mg once daily for 3 days and 500 mg once daily for 5 days and norfloxacin in a dosage of 400 mg BID for 7 days were 137 (92%), 134 (90%), and 133 (94%) of the women, respectively.

Clinical success was the same (97%) in all three groups. Overall, short-course (either 3- or 5-day) therapy with ciprofloxacin was statistically equivalent to conventional (7-day) therapy with either ciprofloxacin or norfloxacin. Single-dose ciprofloxacin therapy was statistically less effective than conventional treatment.

Puig et al. found that strains with a single alteration in GyrA or one change in GyrA plus one in ParC had ciprofloxacin MICs of 0.12 to 2 g/ml. In contrast, those with three or four changes (in GyrA, ParC, and ParE) had higher MICs (8–16 g/ml) ( 120 ). Ser84 to Leu or Tyr and Asp88 to Tyr, Asn, or Gly were the most common alterations in GyrA, which have been linked to resistance in H.

influenza ( 119 ). In ParC, the most common changes were Ser84Ile and Glu88Lys ( 119 ) and Ser84Arg ( 119 ).
