Proquin XR

Depomed, Inc.

Drug Names(s): Ciprofloxacin Gastric Retention, UTIMINX (EU), URITENT (EU)

Description: Ciprofloxacin is a broad spectrum antibiotic that effects a wide range of gram-negative and gram-positive microorganisms. The bactericidal action of ciprofloxacin results from inhibition of the enzymes topoisomerase II (DNA gyrase) and topoisomerase IV, which are required for bacterial DNA replication, transcription, repair, and recombination.

Ciprofloxacin GR was developed using Depomed's Gastric Retention (GR) System technology for preferential absorption in the upper intestine. This technology created an extended-release product that requires dosing only once a day, compared to Cipro's twice-daily dosing.
