Str. 7, Hungary; email: antal.istvan@pharma.semmelweis-univ.hu AB - Most of the commercially available pharmaceutical products for oral administration route are marketed in the tablet dosage forms. However, compression of multiparticulate systems is a challenge for the pharmaceutical research and industry, especially if the individual unit is a coated particle, as the release of the active ingredient depends on the integrity of the coating. In the present study, polymer-coated pellets tableted with different types of excipients (powder, granules, pellets) then were investigated by various tablet-destructive (microscopic) and tablet non-destructive (microfocus X-ray; microCT) imaging methods. The information obtained from the independent evaluation of the in vitro drug release profiles model is confirmed by the results obtained by image analysis, regardless of whether X-ray or stereomicroscopic images of the coated, tableted pellets were used for image analysis. The results of this study show that the novel easy-to-use, fast, and non-destructive MFX method is a good alternative to the already used microscopic image analysis methods regarding the characterization of particulates, compressed into tablets.

In addition, the influence of process parameters (capacity of milling container, applied volume of milling beads, size of the milling medium, milling speed, milling time) on ABZ polymorphic transition has also been investigated. The optimized, milled formula yielded ~ 145.39 times reduction in mean particle size (182.200 ± 1.3130 nm) compared to unmilled dispersion, which demonstrated 13.50 times gain in mean dissolution rate value compared to the unmilled dispersion in medium at pH = 1.2. No lag time values were observed in the dissolution kinetics of the nanosuspension in comparison with the unmilled samples. Moreover, maximal mean solubility value was also improved by 1.45 times compared to the unmilled suspension, in medium at pH = 6.8, supporting the significance of the Ostwald-Freundlich equation. Diffraction pattern comparisons have indicated a polymorphic transition of albendazole to Form II, which was more pronounced in smaller container at high milling speed values and prolonged operations LA - English DB - MTMT ER - TY - CONF AU - Jakab, Géza AU - Fülöp, Viktor AU - Bozó, Tamás AU - Bogdán, Dóra AU - Mazák, Károly AU - Turbucz, Béla AU - Kállai-Szabó, Nikolett AU - Bertalanné Balogh, Emese AU - Antal, István TI - Baicalin tartalmú gyógyszerhordozó rendszerek fejlesztése és formulálása T2 - Gyógyszertechnológiai és Ipari Gyógyszerészeti Konferencia 2019 PY - 2019 SP - EA17 UR - https://m2.mtmt.hu/api/publication/31176468 ID - 31176468 LA - Hungarian DB - MTMT ER - TY - CONF AU - Basa, Bálint AU - Jakab, Géza AU - Fülöp, Viktor AU - Bertalanné Balogh, Emese AU - Antal, István TI - 3D nyomtatás alkalmazási lehetőségei betegközpontú hatóanyag-felszabadító rendszerek formulálásában T2 - Gyógyszertechnológiai és Ipari Gyógyszerészeti Konferencia 2019 PY - 2019 SP - EA24 UR - https://m2.mtmt.hu/api/publication/31176431 ID - 31176431 LA - Hungarian DB - MTMT ER - TY - CONF AU - Fülöp, Viktor AU - Jakab, Géza AU - Tóth, Bence AU - Bertalanné Balogh, Emese AU - Antal, István TI - Nedves Őrlés hatása az albendazol polimorfiájára T2 - Gyógyszertechnológiai és Ipari Gyógyszerészeti Konferencia 2019 PY - 2019 SP - P07 UR - https://m2.mtmt.hu/api/publication/31176327 ID - 31176327 LA - Hungarian DB - MTMT ER - TY - GEN AU - Pápay, Zsófia Edit AU - Fülöp, Viktor AU - Bertalanné Balogh, Emese AU - Kósa, Annamária AU - Vági, Pál AU - Böddi, Béla AU - Klebovich, Imre AU - Antal, István TI - Biodegradable Nanoparticles for Pulmonary Delivery of Apigenin PY - 2018 UR - https://m2.mtmt.hu/api/publication/30757355 ID - 30757355 LA - English DB - MTMT ER -
