/BOXED WARNING/ WARNING: Fluoroquinolones, including Factive, are associated with an increased risk of tendinitis and tendon rupture in all ages. This risk is further increased in older patients usually over 60 years of age, in patients taking corticosteroid drugs, and in patients with kidney, heart and lung transplants.

Fluoroquinolones, including gemifloxacin, cause arthropathy and osteochondrosis in immature animals of various species. The relevance of these adverse effects in immature animals to use in humans is unknown.

Fluoroquinolones, including gemifloxacin, are associated with increased risk of tendinitis and tendon rupture in all age groups. This risk is further increased in older adults (usually those older than 60 years of age), individuals receiving concomitant corticosteroids, and kidney, heart, or lung transplant recipients. Other factors that may independently increase risk of tendon rupture include strenuous physical activity, renal failure, and previous tendon disorders such as rheumatoid arthritis. Tendinitis and tendon rupture have been reported in patients receiving fluoroquinolones who did not have any of these risk factors. Fluoroquinolone-associated tendinitis and tendon rupture most frequently involve the Achilles tendon and may require surgical repair. Tendinitis and tendon rupture in the rotator cuff (shoulder), hand, biceps, thumb, and other tendon sites also reported. Tendon rupture can occur during or following fluoroquinolone therapy and has been reported up to several months after completion of therapy. Advise patients to rest and refrain from exercise and contact a clinician at the first sign of tendinitis or tendon rupture (e.g., pain, swelling, or inflammation of a tendon or weakness or inability to use a joint). Discontinue gemifloxacin if pain, swelling, inflammation, or rupture of a tendon occurs.

FDA Label
Gemifloxacin is a quinolone/fluoroquinolone antibiotic. Gemifloxacin is bactericidal and its mode of action depends on blocking of bacterial DNA replication by binding itself to an enzyme called DNA gyrase, which allows the untwisting required to replicate one DNA double helix into two. Notably the drug has 100 times higher affinity for bacterial DNA gyrase than for mammalian. Gemifloxacin is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria.
Anti-Bacterial Agents

Absorption
Rapidly absorbed from the gastrointestinal tract. The absolute bioavailability averages approximately 71%.
Route of Elimination
Gemifloxacin and its metabolites are excreted via dual routes of excretion.Following oral administration of gemifloxacin to healthy subjects, a mean ( SD) of 61 9.5% of the dose was excreted in the feces and 36 9.3% in the urine as unchanged drug and metabolites. The mean ( SD) renal clearance following repeat doses of 320 mg was approximately 11.6 3.9 L/hr (range 4.6-6 L/hr), which indicates active secretion is involved in the renal excretion of gemifloxacin.
Volume of Distribution
1.66 to 12.12 L/kg
Clearance
renal cl=11.6+/- 3.9 L/hr [Healthy subjects receiving repeat doses of 320 mg orally]
Gemifloxacin, given as an oral tablet, is rapidly absorbed from the gastrointestinal tract. Peak plasma concentrations of gemifloxacin were observed between 0.5 and 2 hours following oral tablet administration and the absolute bioavailability of the 320 mg tablet averaged approximately 71% (95% CI 60%-84%). Following repeat oral doses of 320 mg to healthy subjects, the mean + or - SD maximal gemifloxacin plasma concentrations (Cmax) and systemic drug exposure (AUC (0-24)) were 1.61 + or - 0.51 ug/mL (range 0.70-2.62 ug/mL) and 9.93 + or - 3.07 ug.hr/mL (range 4.71-20.1 ug.hr/mL), respectively. In patients with respiratory and urinary tract infections (n=1423), similar estimates of systemic drug exposure were determined using a population pharmacokinetics analysis (geometric mean AUC (0-24), 8.36 ug.hr/mL; range 3.2 -47.7 ug.hr/mL).

In vitro binding of gemifloxacin to plasma proteins in healthy subjects is approximately 60 to 70% and is concentration independent. After repeated doses, the in vivo plasma protein binding in healthy elderly and young subjects ranged from 55% to 73% and was unaffected by age. Renal impairment does not significantly affect the protein binding of gemifloxacin. The blood-to-plasma concentration ratio of gemifloxacin was 1.2:1. The geometric mean for Vdss/F is 4.18 L/kg (range, 1.66 - 12.12 L/kg). Gemifloxacin is widely distributed throughout the body after oral administration. Concentrations of gemifloxacin in bronchoalveolar lavage fluid exceed those in the plasma. Gemifloxacin penetrates well into lung tissue and fluids.

Gemifloxacin is metabolized to a limited extent by the liver. All metabolites formed are minor (<10% of the administered oral dose); the principal ones are N-acetyl gemifloxacin, the E-isomer of gemifloxacin and the carbamyl glucuronide of gemifloxacin.
Gemifloxacin is metabolized to a limited extent by the liver. The unchanged compound is the predominant drug-related component detected in plasma (approximately 65%) up to 4 hours after dosing. All metabolites formed are minor (<10% of the administered oral dose); the principal ones are N-acetyl gemifloxacin, the E-isomer of gemifloxacin and the carbamyl glucuronide of gemifloxacin. Cytochrome P450 enzymes do not play an important role in gemifloxacin metabolism, and the metabolic activity of these enzymes is not significantly inhibited by gemifloxacin.

The bactericidal action of gemifloxacin results from inhibition of the enzymes topoisomerase II (DNA gyrase) and topoisomerase IV, which are required for bacterial DNA replication, transcription, repair, and recombination.
Like other fluoroquinolone anti-infective agents, gemifloxacin inhibits DNA synthesis in susceptible organisms via inhibition of type II DNA topoisomerases (DNA gyrase, topoisomerase IV). However, unlike many other fluoroquinolones, gemifloxacin targets both DNA gyrase and topoisomerase IV in susceptible S. pneumoniae. Although cross-resistance can occur between gemifloxacin and other fluoroquinolones, gemifloxacin may be active against some strains of S. pneumoniae resistant to ciprofloxacin and other fluoroquinolones.

The fluroquinolone gemifloxacin was examined for its capacity to modulate secretion of cytokines by human monocytes stimulated with lipopolysaccharide (LPS). Monocytes from six male and two female healthy volunteers were stimulated with LPS, exposed to gemifloxacin and the amounts of secreted IL-1 alpha, IL-1 beta, IL-6, IL-10 and TNF-alpha measured at 3, 6 and 24 h. The results revealed that LPS alone increased secretion of each cytokine significantly. Treatment of the LPS-stimulated monocytes with gemifloxacin resulted in a significant inhibition (p < 0.01) of secretion of each of the cytokines from monocytes of the eight volunteers. Nuclear extracts of the human monocyte cell line, THP-1, were used in the electrophoretic mobility shift assay to determine whether gemifloxacin affects nuclear factor-kappa B (NF-kappa B) activation. In addition, RNA from THP-1 cells was used in Northern blots to determine whether inhibition of secretion of IL-1 beta and TNF-alpha by gemifloxacin occurred at the transcription or translation level. Whereas LPS induced a rapid increase in NF-kappa B activation, gemifloxacin alone did not. Gemifloxacin did not affect the kinetics or decrease the extent of activation. Northern blots indicated that the inhibitory activity of gemifloxacin occurred post-transcription. Thus, gemifloxacin may modulate the immune response by altering secretion of cytokines by human monocytes. Although the concentrations of gemifloxacin used were higher than those observed in the serum of human volunteers treated with the dose under clinical development, it should be taken into consideration that concentrations at tissue and intracellular levels may be considerably higher than serum concentrations.

Fluoroquinolones prolong the QT interval by blocking voltage-gated potassium channels, especially the rapid component of the delayed rectifier potassium current I(Kr), expressed by HERG (the human ether-a-go-go-related gene). According to the available case reports and clinical studies, moxifloxacin carries the greatest risk of QT prolongation from all available quinolones in clinical practice and it should be used with caution in patients with predisposing factors for Torsades de pointes (TdP).
