Study Confirms Safety of Combined Eye Drops for Surgery Use
Introduction to the Study
A five-year pharmacovigilance study has confirmed the excellent safety profile of a fixed-dose combination eye drop developed by NTC. This eye drop combines an anti-inflammatory steroid and a quinolone antibiotic, designed for preventing and treating inflammation, as well as preventing infection after cataract surgery.
Study Overview
The findings of this comprehensive research are backed by data gathered from nearly four million patients treated across about sixty countries. Conducted by reputed Italian researchers and supported by NTC, the study utilized safety reports from the adrreports.eu portal, which collects information from EudraVigilance, the official adverse drug reaction database of the European Medicines Agency.
Key Findings
During the analysis, a total of fifty-three adverse drug reactions (ADRs) were reported among twenty-five patients between 2020 and 2024. The study revealed several significant insights:
Adverse Drug Reactions
An impressive seventy-four percent of the reported ADRs were classified as non-serious. More than half of the adverse reactions were deemed unlikely to be related to the medication itself. The most frequently observed side effects were mild reactions affecting either the eye or skin, which are typical for a topically administered ophthalmic solution. Notably, there were no instances of endophthalmitis, a severe infection that can arise after eye surgery.
Expert Opinions
Dr. Giorgio Ciprandi, the senior author of the research, expressed, "This is the first international pharmacovigilance study specifically analyzing a fixed-dose eye drop that combines an antibiotic with an anti-inflammatory steroid. Its widespread use and favorable safety profile render it a valuable option in managing post-cataract patients. Moreover, it supports a much-needed approach in contemporary medicine."
The findings also corroborate the current recommendation for a short-term, seven-day treatment course. This method not only enhances patient adherence but also minimizes the risk of potential side effects or the development of antibiotic resistance.
Importance of Pharmacovigilance
This study underscores the pivotal role of pharmacovigilance in evaluating the safety of medications after market approval. Alessandro Colombo, CSO at NTC, noted, "This analysis demonstrates the necessity of ongoing safety monitoring to safeguard patients and aid healthcare providers with reliable safety information obtained from spontaneous reporting systems."
The significance of post-operative management becomes crucial in ensuring optimal recovery, given that cataract surgery remains the most frequently performed ophthalmic procedure around the globe. The innovative eye drop combination, having gained approval in 2020, offers patients a simplified one-week treatment regimen. This not only reduces unnecessary exposure to antibiotics but also helps mitigate risks associated with long-term steroid use.
Regulatory Recognition
Due to its consistent safety profile, the eye drop product has successfully achieved marketing authorization renewal from the European regulatory authorities, further assuring its compliance with safety standards.
About the Study
Entitled "Pharmacovigilance on dexamethasone 1mg/mL + levofloxacin 5 mg/mL eye drops, solution: a five-year registry," this study was carried out by esteemed professionals in the fields of ophthalmology and drug safety. It highlights the critical need for ongoing surveillance in the field of medication safety, ultimately enhancing patient care and treatment outcomes.
