1. Physical characterization of multiparticulate systems
ABSTRACT The search for new pharmaceutical dosage forms and different drug delivery systems already used in therapeutics is a global trend, serving as an opportunity to expand the portfolio for the pharmaceutical industry. In this context, multiparticulate systems, such as pellets, granules, and minitablets, represent an attractive alternative, given the ran

2. Formulation, preparation and in vitro - in vivo evaluation of compression-coated tablets for the colonic-specific release of ketoprofen
ABSTRACT The aim of this study was to formulate and prepare compression-coated tablets for colonic release (CR-tablets), and to evaluate the bioavailability of ketoprofen following the administration of a single dose from mini-tablets with immediate release (IR-tablets) compared to CR-tablets. CR-tablets were prepared based on time-controlled hydroxypropylme

3. Development of a multiparticulate system containing enteric-release mini-tablets of omeprazole
O presente trabalho teve como objetivo desenvolver e avaliar um sistema multiparticulado de liberação modificada, composto por mini-comprimidos revestidos com polímero de liberação pH-dependente, utilizando como fármaco modelo o omeprazol. Os mini-comprimidos (diâmetro de 2,5 mm) foram obtidos em máquina de compresssão excêntrica, revestidos em lei

4. Development of enteric coated sustained release minitablets containing mesalamine
O presente trabalho teve como objetivo desenvolver e avaliar um sistema multiparticulado de liberação modificada, composto por minicomprimidos com sistema matricial de liberação prolongada revestidos com polímero de liberação pH-dependente, utilizando mesalazina como fármaco modelo. Polyox® WSR 1105 foi o polímero utilizado no sistema matricial e E

5. Desenvolvimento e avaliação de minicomprimidos contendo atorvastatina cálcica / Development and evaluation of minitablets containing atorvastatin calcium
O objetivo do presente trabalho foi desenvolver e avaliar minicomprimidos obtidos a partir de quatro formas polimórficas de atorvastatina cálcica. Inicialmente foi realizada uma caracterização físico-química das amostras (amorfa e formas cristalinas I, VI e VIII), empregando-se os ensaios de dissolução intrínseca e solubilidade através dos métodos

6. The use of artificial neural networks for the selection of the most appropriate formulation and processing variables in order to predict the in vitro dissolution of sustained release minitablets
The objective of this work was to apply artificial neural networks (ANNs) to examine the relative importance of various factors, both formulation and process, governing the in-vitro dissolution from enteric-coated sustained release (SR) minitablets. Input feature selection (IFS) algorithms were used in order to give an estimate of the relative importance of

7. Development and Evaluation of oral multiple-unit and single-unit hydrophilic controlled-release systems
This study compared the release behavior of single-unit (tablets, capsules) and multiple-unit (minitablets in capsules) controlled-release systems of furosemide. The swelling and erosion behaviors of these systems, which contained the swellable hydrophilic polymers sodium alginate (high viscosity) and Carbopol 974P, were compared. Swelling and erosion experi

8. A double blind lipase for lipase comparison of a high lipase and standard pancreatic enzyme preparation in cystic fibrosis.
A standard acid resistant microsphere pancreatic enzyme preparation was compared with identical capsules half filled with mini-tablets of a new high lipase preparation in a randomised double blind crossover study in children with cystic fibrosis. Each patient received his/her usual number of capsules and the same dose of lipase during each period of the stud

9. Design and Evaluation of a Novel Matrix Type Multiple Units as Biphasic Gastroretentive Drug Delivery Systems
A biphasic gastroretentive floating drug delivery system with multiple-unit mini-tablets based on gas formation technique was developed to maintain constant plasma level of a drug concentration within the therapeutic window. The system consists of loading dose as uncoated core units, and prolonged-release core units are prepared by direct compression process
