Prulifloxacin

Prulifloxacin (NM441) is an orally active fluoroquinolone antibiotic with a broad spectrum of activity against Gram-positive and -negative bacteria. Prulifloxacin is a prodrug of a thiazeto-quinoline carboxylic acid derivative Ulifloxacin (NM394). Prulifloxacin has the potential for lower urinary tract infections and exacerbations of chronic bronchitis^[1][2]. In Vivo: After oral administration of NM441 at a dose of 20 mg/kg to dogs, the peak concentration of NM394 in plasma was 2.39 micrograms/ml, whereas it was 0.63 micrograms/ml for NM394 administered alone. NM441 was as effective as ofloxacin and was twice as effective as ciprofloxacin against systemic infection with Staphylococcus aureus. Against infections with streptococci, NM441 was two to three times as effective as ofloxacin and five times as effective as ciprofloxacin^[1].
