Assessment of the Safety and Efficacy of Ciproxan-I.V. in Daily Clinical Practice - Analysis Results From a Post-marketing Surveillance

This study is a post-marketing surveillance in Japan, and it is a local prospective and observational study of patients who have received Ciproxan intravenously as a first-line treatment for sepsis, secondary skin infections followed by superficial burn, post-surgical or post-traumatic, pneumonia, peritonitis, cholecystitis, cholangitis, anthrax. The objective of this study is to assess safety and efficacy of Ciproxan in daily clinical practice. A total of 3,000 patients are to be enrolled and assessed during the period of treatment with Ciproxan.

Prospective, Open-Label, Noncomparative, Multicenter Study to Evaluate the Efficacy and Safety of Ciprofloxacin Extended Release (Cipro XR) 1000 mg Tablets Given Once Daily for 7 to 14 Days in the Treatment of Patients 18 Years or Older With Complicated Urinary Tract Infections Caused by Pseudomonas Aeruginosa and Other Common Uropathogens

Researchers want to find out if a drug called Cipro® XR (ciprofloxacin extended-release) can help people with a complicated urinary tract infection caused by a kind of bacteria called Pseudomonas aeruginosa. The study doctor will give Cipro XR to some people to see if it is safe and works to treat complicated urinary tract infections caused by Pseudomonas aeruginosa. The study doctor will also gather information about using Cipro XR to treat complicated urinary tract infections caused by other bacteria. About 500 people with complicated urinary tract infections who are 18 years old and older will join this study. Cipro XR is approved by the U.S. Food and Drug Administration (FDA) for the treatment of complicated urinary tract infections and acute uncomplicated pyelonephritis (inflammation of the kidney). The dose of Cipro XR used in this study (1000 mg a day for 7 to 14 days), has been shown to be safe and effective. This study is being done to gather more information on using this dose of Cipro XR for complicated urinary tract infections caused by Pseudomonas aeruginosa, as well as by other bacteria.

Dissolution testing of modified release products with biorelevant media: An OrBiTo ring study using the USP apparatus III and IV

During the OrBiTo project, our knowledge on the gastrointestinal environment has improved substantially and biorelevant media composition have been refined. The aim of this study was to propose optimized biorelevant testing conditions for modified release products, to evaluate the reproducibility of the optimized compendial apparatus III (USP apparatus III) and compendial apparatus IV (USP apparatus IV, open-loop mode) dissolution methods and to evaluate the usefulness of these methods to forecast the direction of food effects, if any, based on the results of two «ring» studies and by using two model modified release (MR) products, Ciproxin / Cipro XR and COREG CR. Six OrBiTo partners participated in each of the ring studies. All laboratories were provided with standard protocols, pure drug substance, and dose units. For the USP apparatus III, the dissolution methods applied to Ciproxin / Cipro XR, a monolithic MR product of an active pharmaceutical ingredient (API) with moderate aqueous solubility, were robust with low intra- and inter-laboratory data variability. Data from all partners were in line on a qualitative basis with food effect data in humans. For the USP apparatus IV, the dissolution methods applied to COREG CR, a multiparticulate, pH dependent, MR product of an API with low and pH dependent solubility led to high intra- and inter- laboratory data variability. Data from all partners were in line, on a qualitative basis, with the previously observed food effects in humans.

Urinary excretion of ciprofloxacin after administration of extended release tablets in healthy volunteers. Swellable drug-polyelectrolyte matrix versus bilayer tablets

This paper builds on a previous paper in which new ciprofloxacin extended-release tablets were developed based on a ciprofloxacin-based swellable drug polyelectrolyte matrix (SDPM-CIP). The matrix contains a molecular dispersion of ciprofloxacin ionically bonded to the acidic groups of carbomer, forming the polyelectrolyte-drug complex CB-CIP. This formulation showed that the release profile of the ciprofloxacin bilayer tablets currently commercialised can be achieved with a simpler strategy. Thus, since ciprofloxacin urine concentrations are associated with the clinical cure of urinary tract infections, the goal of this work was to compare the urinary excretion of SDPM-CIP tablets with those of the CIPRO XR® bilayer tablets. A batch of SDPM-CIP tablets was manufactured by the wet granulation method and the CB-CIP ionic complex was obtained in situ. Fasted healthy volunteers received a single oral dose of 500 mg ciprofloxacin of either formulation in a randomised crossover study. Urinary concentrations were assessed by HPLC at intervals up to 36 h. Pharmacokinetic parameters (rate of urinary excretion, maximum urine excretion rate, t_max, area under the curve, amount and percentage of the ciprofloxacin dose excreted in urine) showed no statistical differences between both formulations at any of the time intervals of collection. The processing conditions to obtain SDPM-CIP tablets are easy to scale up since they involve technology currently employed in the pharmaceutical industry and the process is less challenging to implement. In addition, SDPM-CIP tablets met pharmacopoeial quality specifications.

The aim of this trial was to compare the efficacy and safety of extended-release ciprofloxacin (CIPRO XR) versus the immediate-release formulation (CIPRO IR) in the treatment of complicated urinary tract infections (UTIs). 212 patients were randomized to CIPRO XR 1,000 mg tablet once daily or CIPROXIN IR 500 mg tablet twice daily. Treatment efficacy was evaluated by bacteriological outcome. Safety was measured by recording adverse events. The rate of bacteriological eradication was 83% in the CIPRO XR group and 75% in the CIPRO IR. the overall incidence of adverse events reported was higher in the CIPRO IR group. The authors conclude that CIPRO XR is a safe and effective treatment for complicated UTIs. Although the limited data available do not consent to support a statistically superior efficacy or safety compared to CIPRO IR, a trend in favor of CIPRO XR is clearly evident in all efficacy and safety variables. CIPRO XR is associated with reduced frequencies of drug-related adverse events compared to CIPRO IR.
