What is Nadifloxacin?

Description

Nadifloxacin, one of the three new fluoroquinolone antibiotics launched in 1993 is indicated for topical treatment of acne vulgaris and other skin infections. Nadifloxacin has a potent and broad spectrum of activity against aerobic Gram-positive and -negative bacteria and against anaerobic bacteria. It produces significant improvement in patients with Propionibacterium acnes infection and does not appear to cause cross-resistance to other antibiotic agents. Its potent antimicrobial activity has also been demonstrated in the Pseudomonas aeruginosa burn wound infection model in mice. Nadifloxacin exerts its antibiotic activity by inhibiting the formation of supercoiled DNA by DNA gyrase.

Definition

ChEBI: Nadifloxacin is a pyridoquinoline, a hydroxypiperidine, a heteroarylpiperidine and a quinolone antibiotic. It has a role as an antibacterial drug. It is effective against the Gram-positive bacteria S. aureus and P. acnes, as well as Gram-negative bacteria.

brand name

Acuatim

Pharmaceutical Applications

A lipophilic tricyclic fluorobenzoquinoline with a 4- hydroxylpiperinyl moiety at the C-8 position, formulated as a cream for topical use. It is active against many Grampositive bacteria involved in skin infections, including Propionibacterium acnes (MIC 0.25–2.0 mg/L), and Staph. aureus (MIC 0.015–2 mg/L). It appears to inhibit the generation of reactive oxygen species by neutrophils. The sodium salt is used as a 1% cream for use in acne vulgaris and cutaneous staphylococcal infections.
