Hypothesis
This study investigated the pharmacokinetics of topically administered pirfenidone (0.5%) in rabbit eyes.
Conclusion
Topical administration of pirfenidone may be an effective approach for modulation of wound healing responses in glaucoma filtration surgical site.
Supporting Evidence
- Pirfenidone concentrations peaked within 20 minutes in ocular tissues.
- The mean maximum concentrations of pirfenidone varied across different ocular tissues.
- The half-life of pirfenidone in ocular tissues ranged from 15.71 to 70.91 minutes.
- Measurable concentrations of pirfenidone were achieved in various ocular tissues after topical application.
Takeaway
The study shows that putting a medicine called pirfenidone in rabbit eyes helps it spread quickly and work well to heal wounds.
Methodology
Pirfenidone solution was instilled into the rabbit’s conjunctival sac, and ocular tissues were obtained at various time points for analysis.
Limitations
The study was conducted in rabbits, and results may not directly apply to humans.
Participant Demographics
Sixty Albino rabbits, weighing 2–2.5 kg each.
