Abstract
The main objective of this novel study was to develop chlorpheniramine maleate orally disintegrating films (ODF) using hot-melt extrusion technology and evaluate the characteristics of the formulation using in vitro and in vivo methods. Modified starch with glycerol was used as a polymer matrix for melt extrusion. Sweetening and saliva-simulating agents were incorporated to improve palatability and lower the disintegration time of film formulations. A standard screw configuration was applied, and the last zone of the barrel was opened to discharge water vapors, which helped to manufacture non-sticky, clear, and uniform films. The film formulations demonstrated rapid disintegration times (6-11s) and more than 95% dissolution in 5min. In addition, the films had characteristic mechanical properties that were helpful in handling and storage. An animal model was employed to determine the taste masking of melt-extruded films. The lead film formulation was subjected to a human panel for evaluation of extent of taste masking and disintegration.

Abstract
Since hydrophilic matrices were proposed for controlled drug delivery, many polymeric excipients have been studied to make drug release fit the desired profiles. It has been pointed out that lambda-carrageenan, a sulfated polymer from algae, can suitably control the release rate of basic drugs from hydrophilic matrices. Furthermore, the relevance of hydrophobic interactions in drug-polymer aqueous systems has already been demonstrated, although no references to morphological features as well as to the kinetics of the interaction complexes formation have been published to date. In this work, we propose a method to monitor the topographical evolution of the interaction between lambda-carrageenan and dexchlorpheniramine maleate, in order to determine how the release profiles can be so easily controlled. For this purpose, solutions of both polymer and drug were prepared at very low concentration. Solutions were mixed and small volumes were taken every hour for over a period of 24 h and subsequently analyzed. The characterization technique used, atomic force microscopy, provides a high resolution, allowing plotting of three-dimensional images of the sample morphology within the nanometric scale. The results demonstrate that lambda-carrageenan is able to nanoencapsulate spontaneously dexchlorpheniramine maleate molecules, which offers the possibility of controlling the release rate of the drug with no need of complex technological processes. Moreover, this work demonstrates the suitability of atomic force microscopy for the specific case of the on-time monitoring of interaction processes that occur in pharmaceutical systems.

Abstract
The purpose of this investigation was to determine the effects of thermal processing and post-processing thermal treatment on the release properties of chlorpheniramine maleate (CPM) from matrix tablets containing Eudragit RS PO and triethyl citrate (TEC). CPM tablets containing Eudragit RS PO with and without TEC were prepared by direct compression (DC), high shear hot-melt granulation (HMG), and hot-melt extrusion (HME). X-ray diffraction patterns showed that the CPM was distributed in Eudragit RS PO at the molecular level following HME. The thermogravimetry analysis (TGA) profiles of CPM, Eudragit RS PO, and TEC demonstrated that these materials were thermally stable during both the high shear HMG and HME processes. The tablets were subjected to post-processing thermal treatment by storing the tablets at 60 degrees C in open containers for 24 hr. Tablets prepared by DC showed the highest drug release rate constant of 36.2% hr-1/2. When 4% TEC was incorporated into the formulation, the drug release rate constant for the directly compressed tablets decreased to 32.4% hr-1/2. After high shear HMG and HME of the powder blend containing 4% TEC, the drug release rate constant decreased to 30.8 and 13.8% hr-1/2 for the respective processes. The drug release rate constants for all tablets decreased following post-processing thermal treatment. The reduction in release rate was due to an increase in the intermolecular binding and entanglement between drug molecules and polymer molecules that occurred during thermal processing. Post-processing thermal treatment of the hot-melt extrudates had a minimal effect on the drug release rate since the HME process enhanced the drug and polymer entanglement to a greater extent.
