چکیده
Amaç: Farklı üç süper dağıtıcının, ki bunlar; kroskarmeloz sodyum, sodyum nişasta glikolat ve Indion 414, doğrudan basım ile hazırlanan salbutamol sülfat oral dağılan tabletlerinde (ODT) hızlı dağıtma etkisi için ayrı ayrı veya ikili kombinasyonlarında çalışıldı. Gereç ve Yöntemler: ODT’ler farklı üç süper dağıtıcı kombinasyonunda; A, B ve C, hazırlandı. Herbir kombinasyonda süperdağıtıcıların 10:90, 25:75, 50:50, 75:25 ve 90:10 oranlarında beş formülasyon hazırlandı. Üç ODT formülasyonu tek süper dağıtıcı ile ve iki ODT serisi piyasadaki ODT eksipiyanları ile ki bunlar, Prosolv-ODT ve F-Melt, hazırlandı. Hazırlanan ODT formülasyonları ağırlık sapması, sertlik, friabilite, ıslanma zamanı, dağılma ve etken madde salımı için değerlendirildi ve karşılaştırıldı. Bulgular: Tüm ODT’ler 32s veya daha kısa sürede dağıldı. Croscarmellose sodyum, sodyum nişasta glikolat içeren F3 ODT formülasyonu 19.28±3.11 s de çok hızlı dağıldı. F3’ün sonuçları piyasadaki koproses eksipiyanları içeren serilerle (F19 ve F20) karşılaştırıldı ve çeşitli değerlendirme parametreleri için iyi bir uyum olduğu bulundu. F20 formülasyonu higroskopik iken F3 formülasyonunda bu dezavantaj yoktu. Sonuç: Böylece, kombinasyondaki süper dağıtıcıların farklı mekanizmalarına bağlı olarak olası ilave ve/veya sinerjik dağılmayı sağlayabileceği sonucuna varabiliriz. Anahtar kelimeler: Islanma, dağılma, çözünme, kroskarmeloz sodyum, sodyum nişasta glikolat, Indion 414 Objectives: Superdisintegrants play important role in disintegration of orally disintegrating tablets (ODTs). Action of three different superdisintegrants, viz. croscarmellose sodium, sodium starch glycolate and Indion 414, were studied individually or in their binary combinations for their fast disintegrant action in ODTs of salbutamol sulphate prepared by direct compression. Materials and Methods: ODTs were prepared in three different superdisintegrant combinations A, B and C. In each combination, five formulations were prepared with superdisintegrants in ratios 10:90, 25:75, 50:50, 75:25, and 90:10. Three ODT formulations were prepared with single superdisintegrant and two ODT batches were prepared from marketed ODT excipient blends, viz. Prosolv-ODT and F-Melt. Prepared ODT formulations were evaluated and compared for weight variation, hardness, friability, wetting time, disintegration and drug release. Results: All ODTs disintegrated quickly in 32 s or less. ODT formulation F3, containing croscarmellose sodium and sodium starch glycolate, disintegrated very quickly in 19.28±3.11 s. Results of F3 were compared with the batches (F19 and F20) containing marketed coprocessed excipients and found in good agreement for various evaluation parameters. Formulation F20 was hygroscopic, while F3 did not suffer this disadvantage. Conclusion: Thus, we may conclude that superdisintegrants in combinations may offer additive and/or synergistic disintegration possible due to their different mechanism.
