Dexibuprofen enteric film-coated tablets: design, characterization and pharmacokinetic analysis in human volunteers.
Objective: This study aimed to develop a stable and scalable enteric film-coated tablet for the gastric irritant dexibuprofen.
Methods: Utilizing direct compression with super-disintegration (crospovidone), the optimal core batches were coated with Opadry white seal coat and enterically coated with Eudragit®L100 with pigment (Talc), demonstrating a 12% weight increase; release and integrity were assessed using specific pH buffers and SEM, with stability testing confirming a six-month shelf life at 40 °C and 75% RH.
Results: The optimized formulation achieved 99.87% release in phosphate buffer within 60 min, maintained integrity for 120 min in acidic conditions, and exhibited superior bioavailability compared to Innovifen with relative bioavailability ≈of 121% and elevated Cmax (18.35 µg/ml compared to 11.1 µg/ml).
Conclusion: These results highlight the potential of this formulation to enhance patient safety and efficacy through delayed enteric technology and fast intestinal release.
