Impact of Properties of Hydrated Silicon Dioxide as Core Material on the Characteristics of Drug-containing Particles Prepared by the 2-step Process Melt Granulation Technology, MALCORE ®.

[PMID: 36577811 DOI: 10.1208/s12249-022-02492-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Accepted: 12/14/2022] [Indexed: 12/30/2022] Open
Abstract
Drug-containing particles (DCPs) are frequently used as cores in the development of solid oral dosage forms. The wet layering technique, which is a typical approach for preparing DCPs, requires the use of solvents and a long manufacturing time. In our previous study, we developed a novel manufacturing technology, MALCORE®, which can solve these problems through melt granulation. However, particle size control methods for DCPs in MALCORE® and the effect of the physical properties of the hydrated silicon dioxide (HSD) used for the core have not been clarified. The aim of this study was to examine the effects of the particle and pore sizes of HSD on the properties of the prepared DCPs. The results showed that the DCPs prepared using MALCORE® could be controlled by the particle size of HSD. The drug-loading efficiency tended to decrease as HSD particle size increased. Additionally, the amount of drug layering in DCPs increased as the pore size of HSD increased, but HSDs with a pore size much larger than the particle size were not able to properly layer the drug. These findings are helpful for applying MALCORE® to a variety of oral drug formulations.

Lu CH, Huang YF, Chu IM. Design of Oral Sustained-Release Pellets by Modeling and Simulation Approach to Improve Compliance for Repurposing Sobrerol. Pharmaceutics 2022; 14:pharmaceutics14010167. [PMID: 35057064 PMCID: PMC8777650 DOI: 10.3390/pharmaceutics14010167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 12/20/2021] [Accepted: 01/07/2022] [Indexed: 12/10/2022] Open
Abstract
Sobrerol, an oral mucolytic agent, in a recent study showed promise for treating multiple sclerosis. A human equivalent dose of 486 mg of sobrerol administered thrice daily (i.e., 1459 mg of daily dose) demonstrated the highest therapeutic efficacy for repurposing use, which also points out the poor compliance of administration. In this study, oral sustained-release pellets of sobrerol were successfully developed with evaluated manufacturing conditions and drug release kinetics. For design of the target drug product, we used a modeling and simulation approach to establish a predictive model of oral pharmacokinetic profile, by exploring the characteristics and correlations corresponding to the pharmacokinetics and pharmacodynamics of sobrerol, such as absorption lag time (0.18 h), time-scaling in vitro–in vivo correlation (tin-vitro = 0.494 tin-vivo − 0.0904), gastrointestinal transit time (8 h), minimum effective concentration (1.61 μg/mL), and duration of action (12.8 h). Results showed that the frequency of administration and the daily dose remarkably reduced by 33.3% (i.e., from thrice to twice daily) and 22.8%, respectively, which indicates that this prototype approach can be adopted for rapidly developing a modified-release dosage form of sobrerol, with improvement of compliance of administration and therapeutic efficacy.

Assessment of Mini-Tablets Coating Uniformity as a Function of Fluid Bed Coater Inlet Conditions. Pharmaceutics 2021; 13:pharmaceutics13050746. [PMID: 34070006 PMCID: PMC8157842 DOI: 10.3390/pharmaceutics13050746] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Revised: 05/10/2021] [Accepted: 05/13/2021] [Indexed: 11/17/2022] Open
Abstract
This study concerned the quality of mini-tablets’ coating uniformity obtained by either the bottom spray chamber with a classical Wurster distributor (CW) or a swirl distributor (SW). Mini-tablets with a diameter of 2.0, 2.5, and 3.0 mm were coated with hypromellose using two different inlet air distributors as well as inlet airflow rates (130 and 156 m3/h). Tartrazine was used as a colorant in the coating layer and the coating uniformity was assessed by spectrophotometric analysis of solutions obtained after disintegration of the mini-tablets (n = 100). Higher uniformity of coating material distribution among the mini-tablets was observed in the case of SW distributor, even for the biggest mini-tablets (d = 3.0 mm), with an RSD no larger than 5.0%. Additionally, coating thickness was evaluated by colorimetric analysis (n = 1000), using a scanner method, and expressed as a hue value. A high correlation (R = 0.993) between inter-tablet variability of hue and UV-Vis results was obtained. Mini-tablets were successfully coated in a fluid bed system using both a classical Wurster distributor as well as a swirl generator. However, regardless of the mini-tablets’ diameter, better film uniformity was achieved in the case of a distributor with a swirl generator.

Development and evaluation of an omeprazole-based delayed-release liquid oral dosage form. Int J Pharm 2019; 567:118416.

Abstract
Modified-release oral dosage forms are commonly used in pharmaceutics to delay or sustain the release of drugs. Nowadays, they are only marketed as solid dosage forms such as capsules or tablets. Therefore, the development of a liquid oral dosage form with modified-release properties has been keenly awaited to increase the compliance of patients with a swallowing impairment, such as paediatric, older or critically ill patients. In this study, a new technology has been developed that consists of multi-layered particles suspended extemporaneously in a syrup, using omeprazole as a model drug. The coating procedure was optimized to obtain a yield of minimum 90% w/w and a mean diameter below 500 µm. Eudragit® E100 and Eudragit® L100-55 were used to prevent the early release of omeprazole in the syrup and in the acidic environment of the stomach, respectively. These polymers allowed the stability of the coated particles to be ensured when dispersed in a liquid and the enteric release of the drug to be targeted. It was demonstrated that our new system presented similar release performances to existing marketed enteric dosage forms. It is able to protect omeprazole for 2 h in acidic medium at pH 1.2, while omeprazole was entirely released at pH 6.8 within 45 min. Once the final suspension is prepared extemporaneously, it presents sufficient stability to guarantee the administration of multiple doses filled into a syrup bottle and kept for a limited storage time at room temperature (e.g. up to 10 doses to be administered within 10 days).

Film coating of nifedipine extended release pellets in a fluid bed coater with a Wurster insert. BIOMED RESEARCH INTERNATIONAL 2014; 2014:520758.

Abstract
The objective of this work was to study the coating process of nifedipine extended release pellets using Opadry and Opadry II, in a fluid bed coater with a Wurster insert. The coating process was studied using a complete experimental design of two factors at two levels for each polymer. The variables studied were the inlet air temperature and the coating suspension flow rate. The agglomerate fraction and coating efficiency were the analyzed response variables. The air temperature was the variable that most influenced the coating efficiency for both polymers. In addition, a study of the dissolution profiles of coated and uncoated pellets using 0.5% sodium lauryl sulfate in simulated gastric fluid without enzymes (pH 1.2) was conducted. The results showed a prolonged release profile for the coated and uncoated pellets that was very similar to the standards established by the U.S. Pharmacopoeia. The drug content and the release profiles were not significantly affected by storage at 40°C and 75% relative humidity. However, when exposed to direct sunlight and fluorescent light (light from fluorescent bulbs), the coated pellets lost only 5% of the drug content, while the uncoated ones lost more than 35%; furthermore, the dissolution profile of the uncoated pellets was faster.
