Iquix (Levofloxacin Ophthalmic) - Summary



IQUIX® (levofloxacin ophthalmic solution) 1.5% is a sterile topical ophthalmic solution. Levofloxacin is a fluoroquinolone antibacterial active against a broad spectrum of Gram-positive and Gram-negative ocular pathogens. Levofloxacin is a fluorinated 4-quinolone containing a six-member (pyridobenzoxazine) ring from positions 1 to 8 of the basic ring structure. Levofloxacin is the pure(-)-(S)-enantiomer of the racemic drug substance, ofloxacin. It is more soluble in water at neutral pH than ofloxacin.

IQUIX® solution is indicated for the treatment of corneal ulcer caused by susceptible strains of the following bacteria:


*Efficacy for this organism was studied in fewer than 10 infections.
Corynebacterium species*
Staphylococcus aureus
Staphylococcus epidermidis
Streptococcus pneumoniae
Viridans group streptococci*

Pseudomonas aeruginosa
Serratia marcescens*

Published Studies Related to Iquix (Levofloxacin Ophthalmic)

Aqueous and vitreous penetration of linezolid and levofloxacin after oral administration. [2010.12]
PURPOSE: To evaluate the time course of drug concentrations achieved in aqueous (AQ), vitreous (V), and serum (S) compartments after oral administration of linezolid and levofloxacin. DESIGN: Randomized, clinical trial... CONCLUSIONS: Single concomitant doses of linezolid and levofloxacin achieved AQ and V concentrations above the minimum inhibitory concentration for 90% of common ocular gram-positive and gram-negative pathogens up to 12 h after administration. The combination of linezolid and levofloxacin represents a viable option for the prophylaxis and management of endophthalmitis.

Short-term comparative study of the effects of preserved and unpreserved topical levofloxacin on the human ocular surface. [2010.12]
PURPOSE: To compare the short-term effects of preserved and unpreserved topical levofloxacin on the ocular surface of preoperative patients with age-related cataracts... CONCLUSION: Regarding the short-term effects on the ocular surface of patients with age-related cataracts, no clinically and statistically significant differences were observed between topical levofloxacin preserved with BOB and its unpreserved counterpart.

Tear concentration and safety of levofloxacin ophthalmic solution 1.5% compared with ofloxacin ophthalmic solution 0.3% after topical administration in healthy adult volunteers. [2010.03]
PURPOSE: This study evaluated the tear concentration and safety of levofloxacin ophthalmic solution 1.5%... CONCLUSION: A single dose of levofloxacin 1.5% produced tear fluid concentrations that were well above the minimum inhibitory concentration90 for typical ocular pathogens and was safe and well tolerated.

A prospective study determining the efficacy of topical 0.5% levofloxacin on bacterial flora of patients with chronic blepharoconjunctivitis. [2009.07]
BACKGROUND: To determine the efficacy of conjunctival bacterial eradication following a 1-day, 3-day and 7-day application of topical 0.5% levofloxacin, with and without eyelid scrub, in patients with chronic blepharoconjunctivitis (CBC)... CONCLUSIONS: CBC eyes have a significantly higher number of positive cultures than eyes without CBC. The application of topical 0.5% levofloxacin for at least 3 days provided a significant reduction in the number of positive cultures as well as the number of bacteria harbored on the conjunctival surface.

Increased anterior chamber penetration of topical levofloxacin 0.5% after pulsed dosing in cataract patients. [2009.03]
PURPOSE: This study aimed to investigate the rise in aqueous humour (AH) levels of levofloxacin after a specific perioperative pulsed topical drop regimen... CONCLUSIONS: This is the first study to measure AH levels of levofloxacin after postoperative pulsed dosing in humans. Higher AH levels were found than in previously reported studies in which only preoperative drops were given and levels were measured at the time of surgery. Levels of levofloxacin continued to rise for 60 mins after administration of the last postoperative drop, demonstrating that delivery and maintenance of effective antibiotic levels may be achievable with alternative dosing schedules.

Clinical Trials Related to Iquix (Levofloxacin Ophthalmic)

Intravenous Azithromycin Plus Intravenous Ceftriaxone Followed by Oral Azithromycin With Intravenous Levofloxacin Followed by Oral Levofloxacin for the Treatment of Moderate to Severely Ill Hospitalized Patients With Community Acquired Pneumonia [Completed]
A trial in which patients over 18 years of age who are hospitalized with community acquired pneumonia and are otherwise eligible for entry into the study are randomly selected to receive one of two treatment regimens. After written informed consent is obtained, patients will receive one of the following two treatment regimens: 1) intravenous administration of azithromycin and ceftriaxone followed by azithromycin tablets, or 2) intravenous administration of levofloxacin followed by levofloxacin tablets. At least four study visits are normally conducted up to approximately one month after starting therapy. The objective of this study is to compare the safety and efficacy of the two treatment regimens.

Levofloxacin in Preventing Infection in Young Patients With Acute Leukemia Receiving Chemotherapy or Undergoing Stem Cell Transplantation [Recruiting]
This randomized phase III trial studies how well levofloxacin works in preventing infection in young patients with acute leukemia receiving chemotherapy or undergoing stem cell transplant. Giving antibiotics may be effective in preventing or controlling early infection in patients receiving chemotherapy or undergoing stem cell transplant for acute leukemia. It is not yet known whether levofloxacin is effective in preventing infection.

Efficacy of Seven-day Combined Rabeprazole Plus Levofloxacin Plus Augmentin for Eradication of Helicobacter Pylori [Terminated]
This prospective controlled randomized open-label clinical trial is designed to determine the eradication rate of 7-day levofloxacin, amoxicillin/clavulanate and rabeprazole regimen compared with 7-day standard triple therapy for adults infected with Helicobacter pylori in Eastern Taiwan.

Bismuth Improves the Efficacy of Levofloxacin-containing Triple Therapy for Helicobacter Pylori Treatment [Completed]
To examine and compare the efficacy of 2 week Levofloxacin-containing therapies with and without Bismuth for H. pylori treatment.

"Efficacy and Safety of Levofloxacin vs Isoniazid in Latent Tuberculosis Infection in Liver Transplant Patients". [Terminated]
A multicenter, prospective, non-inferiority, randomized and open clinical trial comparing levofloxacin with isoniazid in the treatment of latent tuberculosis infection in patients eligible for liver transplantation. Patients over 18 years of age on the waiting list for liver transplantation. Sample size: n=870 patients. HYPOTHESIS Levofloxacin treatment of latent tuberculosis infection, begun while on the waiting list for liver transplantation, is safer and not less effective than isoniazid treatment begun after transplantation when liver function is stable.
