Introduction:
Chemotherapy-induced nausea and vomiting (CINV) limits treatment adherence; this study aimed to develop optimized Granisetron hydrochloride buccal tablets to improve therapeutic performance and bioavailability.
Methods:
Tablets were prepared by direct compression and optimized using response surface methodology with HPMC K4M (X1) and carbomer 934P (X2). Compatibility was assessed by FT-IR and DSC, while mucoadhesion, t50, drug release, kinetics, and pharmacokinetics were evaluated.
Results:
No drug-excipient interactions were observed. The optimized formulation (F3; 50 mg HPMC K4M and 15 mg carbomer 934P) showed adequate mucoadhesion (8.25 ± 0.12 g), prolonged release (t50 ≈ 323 ± 0.35 min), and 70.23% ± 2.14% release at 8 h. Release followed the korsmeyer-peppas model, indicating anomalous transport. Pharmacokinetic studies showed significantly higher Cmax and AUC than oral tablets (p < 0.04).
Discussion:
The optimized buccal system provides controlled release and enhanced pharmacokinetic performance, suggesting a promising alternative approach for effective CINV management.
