Read more Acute Bacterial Skin and Skin Structure Infections : Delafloxacin is indicated in adults for the treatment of acute bacterial skin and skin structure infections (ABSSSI) caused by the following susceptible microorganisms: Staphylococcus aureus (including methicillin-resistant [MRSA] and methicillin-susceptible [MSSA] isolates), Staphylococcus haemolyticus, Staphylococcus lugdunensis, Streptococcus agalactiae, Streptococcus anginosus Group (including Streptococcus anginosus, Streptococcus intermedius, and Streptococcus constellatus), Streptococcus pyogenes, Enterococcus faecalis, Escherichia coli, Enterobacter cloacae, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Community-Acquired Bacterial Pneumonia : Delafloxacin is indicated in adults for the treatment of community-acquired bacterial pneumonia (CABP) caused by the following susceptible microorganisms: Streptococcus pneumoniae, Staphylococcus aureus (methicillin-susceptible [MSSA] isolates only), Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, Haemophilus influenzae, Haemophilus parainfluenzae, Chlamydia pneumoniae, Legionella pneumophila, and Mycoplasma pneumoniae.

Delafloxacin inhibits the activity of bacterial DNA topoisomerase IV and DNA gyrase (topoisomerase II). This interferes with bacterial DNA replication by preventing the relaxation of positive supercoils introduced as part of the elongation process. The resultant strain inhibits further elongation. Delafloxacin exerts concentration-dependent bacteriocidal activity. The antibacterial activity of delafloxacin appears to best correlate with the ratio of area under the concentration-time curve of free delafloxacin to minimal inhibitory concentration ( f AUC/MIC) for Gram-positive organisms such as Staphylococcus aureus and Gram-negative organisms such as Escherichia coli based on animal models of infection.

Route of administration : Intravenous (IV) Injection Indications Dosage and Route of Administration Total Duration (days) Acute Bacterial Skin and Skin Structure Infections (ABSSSI) 300 mg of Delafloxacin Injection every 12 hours over 60 minutes by intravenous infusion 5 to 14 Community-Acquired Bacterial Pneumonia (CABP) 5 to 10 Hepatic Impairment : No dosage adjustment is necessary for Delaflox (Delafloxacin) in patients with hepatic impairment. Renal Impairment : Dosage adjustment is required for patients with severe renal impairment (eGFR 15-29 mL/min/1.73m2). In patients with severe renal impairment or ESRD (eGFR of < 15 mL/min/1.73 m2), accumulation of the intravenous vehicle, sulfobutylether-β-cyclodextrin (SBECD) occurs. Serum creatinine levels should be carefully monitored in patients in such case. If serum creatinine level increases, consider switching to oral Delafloxacin. Discontinue Delafloxacin if eGFR decreases to < 15 mL/min/1.73 m2.

Delafloxacin is contraindicated in patients with known hypersensitivity to Delafloxacin or any of the fluoroquinolone class of antibacterial drugs. Discontinue Delafloxacin at the first appearance of a skin rash or any other sign of hypersensitivity

The limited available data with Delafloxacin use in pregnant women are insufficient to inform a drug-associated risk of major birth defects and miscarriages. There are no data available on the presence of Delafloxacin in human milk, the effects on the breast-fed infant or the effects on milk production.

Fluoroquinolones have been associated with disabling and potentially irreversible serious adverse reactions. Commonly seen adverse reactions include tendinitis, tendon rupture, arthralgia, myalgia, peripheral neuropathy and CNS effects (hallucinations, anxiety, depression, insomnia, severe headaches, and confusion). Discontinue Delafloxacin immediately at the first signs or symptoms of any serious adverse reaction Fluoroquinolones have been associated with an increased risk of tendinitis and tendon rupture in all ages. Tendinitis or tendon rupture can occur, within hours or days of starting a fluoroquinolone, or even several months after completion of fluoroquinolone therapy. Tendinitis and tendon rupture can occur bilaterally. Discontinue Delafloxacin immediately if the patient experiences pain, swelling, inflammation or rupture of a tendon. Fluoroquinolones have been associated with an increased risk of peripheral neuropathy. Cases of sensory or sensorimotor axonal polyneuropathy affecting small and/or large axons resulting in paresthesias, hypoesthesias, dysesthesias and weakness have been reported in patients receiving fluoroquinolones, including Delafloxacin. Discontinue Delafloxacin immediately if the patient experiences symptoms of peripheral neuropathy. Fluoroquinolones, including Delafloxacin, have been associated with an increased risk of psychiatric adverse reactions. Toxic psychosis; hallucinations or paranoia; depression or suicidal thoughts or acts; delirium, disorientation, confusion or disturbances in attention; anxiety, agitation or nervousness; insomnia or nightmares; memory impairment may occur. Discontinue Delafloxacin immediately if the patient experiences symptoms. Fluoroquinolones have been associated with an increased risk of seizures (convulsions), increased intracranial pressure (including pseudotumor cerebri), dizziness and tremors. Discontinue Delafloxacin immediately if the patient experiences symptoms. Fluoroquinolones have neuromuscular blocking activity and may cause muscle weakness in persons with myasthenia gravis. Avoid Delafloxacin in patients with known history of myasthenia gravis. Serious and occasionally fatal hypersensitivity (anaphylactic) reactions, have been reported in patients receiving fluoroquinolone therapy. Some reactions were accompanied by cardiovascular collapse, loss of consciousness, tingling, pharyngeal or facial edema, dyspnea, urticarial and itching. Discontinue Delafloxacin at the first appearance of a skin rash or any other sign of hypersensitivity. Clostridium difficile-associated diarrhea (CDAD) has been reported in users of nearly all systemic antibacterial drugs, including Delafloxacin, with severity ranging from mild diarrhea to fatal colitis. Increased risk of aortic aneurysm and dissection have been reported within two months following use of fluoroquinolones, particularly in elderly patients. Fluoroquinolones have been associated with disturbances of blood glucose, including symptomatic hyperglycemia and hypoglycemia, usually in diabetic patients receiving concomitant treatment with an oral hypoglycemic agent or with insulin. In these patients, careful monitoring of blood glucose is recommended. Severe cases of hypoglycemia resulting in coma or death have been reported with other fluoroquinolones. If a hypoglycemic reaction occurs, discontinue Delafloxacin immediately. Delafloxacin can make you feel dizzy and lightheaded. Do not drive, operate machinery or do other activities that require mental alertness or coordination until you know how Delafloxacin affects you.
