Abstract
Site-specific colon drug delivery is a practical approach for the treatment of local diseases of the colon with several advantages such as rapid onset of action and reduction of the dosage of the drug as well as minimization of harmful side effects. 5-aminosalicylic acid (5-ASA) is a drug of choice in the treatment of inflammatory bowel disease and colitis. For the efficient delivery of this drug, it is vital to prevent 5-ASA release in the upper part of the gastrointestinal tract and to promote its release in the proximal colon. Different approaches including chemical manipulation of drug molecule for production of prodrugs or modification of drug delivery systems using pH-dependent, time-dependent and/or bacterially biodegradable materials have been tried to optimize 5-ASA delivery to the colon. In the current review, the different strategies utilized in the design and development of an oral colonic delivery dosage form of 5-ASA are presented and discussed.

Abstract
A unique biodegradable, superporous, swellable and pH sensitive nanocellulose reinforced chitosan hydrogel with dynamic mechanical properties was prepared for oral administration of curcumin. Curcumin, a less water-soluble drug was used due to the fact that the fast swellable, superporous hydrogel could release a water-insoluble drug to a great extent. CO₂ gas foaming was used to fabricate hydrogel as it eradicates using organic solvents. Field emission scanning electron microscope images revealed that the pore size significantly increased with the formation of widely interconnected porous structure in gas foamed hydrogels. The maximum compression of pure chitosan hydrogel was 25.9 ± 1 kPa and it increased to 38.4 ± 1 kPa with the introduction of 0.5% cellulose nanocrystals. In vitro degradation of hydrogels was found dependent on the swelling ratio and the amount of CNC of the hydrogel. All the hydrogels showed maximum swelling ratios greater than 300%. The 0.5% CNC-chitosan hydrogel showed the highest swelling ratio of 438% ± 11%. FTIR spectrum indicated that there is no interaction between drug and ingredients present in hydrogels. The drug release occurred in non-Fickian (anomalous) manner in simulated gastric medium. The drug release profiles of hydrogels are consistent with the data obtained from the swelling studies. After gas foaming of the hydrogel, the drug loading efficiency increased from 41% ± 2.4% to 50% ± 2.0% and release increased from 0.74 to 1.06 mg/L. The drug release data showed good fitting to Ritger-Peppas model. Moreover, the results revealed that the drug maintained its chemical activity after in vitro release. According to the results of this study, CNC reinforced chitosan hydrogel can be suggested to improve the bioavailability of curcumin for the absorption from stomach and upper intestinal tract.

Abstract
Spray-dried dispersions (SDDs) are fascinating polymer-drug mixtures that exploit the amorphous state of a drug to dramatically elevate its apparent aqueous solubility above equilibrium. For practical usage in oral delivery, understanding how polymers mechanistically provide physical stability during storage and prevent supersaturated drugs from succumbing to precipitation during dissolution remains a formidable challenge. To this end, we developed a versatile polymeric platform with functional groups analogous to hydroxypropyl methyl cellulose acetate succinate (HPMCAS, a heterogeneous leading excipient candidate for SDDs) and studied its interactions with Biopharmaceutical Classification System Class II drug models probucol, danazol, and phenytoin at various dosages. By conducting reversible addition-fragmentation chain transfer polymerizations with monomeric components chemically analogous to HPMCAS, we synthetically dismantled the highly polydisperse architecture of HPMCAS into well-defined polymer systems (i.e., targetable Mn, Đ < 1.3, tunable Tg). In the powdered SDD form, by wide-angle X-ray diffraction all HPMCAS analogs yielded amorphous danazol and phenytoin up to 50 wt % loading, whereas for probucol, hydrophobic methoxy functionality and high polymeric Tg were key to inhibit immediate partitioning into crystalline domains. Nonsink in vitro dissolution tests revealed distinct release profiles. The polymer containing only acetyl and succinoyl substituents spray-dried with probucol increased the area under the dissolution curve by a factor of 180, 112, and 26 over pure drug at 10, 25, and 50 wt % loading, respectively. For crystallization-prone danazol and phenytoin, we observed that the water-soluble polymer with hydroxyl groups inhibited crystal growth and enabled high burst release and supersaturation maintenance. Our findings provide fundamental insight into how excipient microstructures can complex with drugs for excipient formulation applications.

Abstract
Colorectal cancer (CRC) is the third most common cause of cancer-related death in both men and women. Often, surgical intervention remains the choice in treating CRC. Traditional dosage forms used for treating CRC deliver drug to wanted as well as unwanted sites of drug action resulting in several adverse side effects. Targeted oral drug delivery systems are being investigated to target and deliver chemotherapeutic and chemopreventive agents directly to colon and rectum. Site-specific delivery of a drug to colon increases its concentration at the target site, and thus requires a lower dose with reduced incidence of side effects. The major obstacle to be overcome for successful targeting of drug to colon through oral route is that drug absorption/degradation must be avoided in stomach and small intestine before the dosage form reaches colon. The review includes discussion of physiological factors that must be considered when targeting drugs directly to colorectal region, an outline on drugs used for treatment and prevention of CRC, and a brief description of various types of colon-targeted oral drug delivery systems. The focus is on the assessment of various formulation approaches being investigated for oral colon-specific delivery of drugs used in the treatment and prevention of CRC.

Abstract
The preparation, characterization, and in vitro release of 5-aminosalicylic acid (5-ASA) from methacrylic acid (MAA)/perlite composites (APC) prepared via a sol–gel route are reported. The free-radical graft polymerization of methacrylic acid (MAA) onto perlite particles was studied experimentally. The grafting procedure consisted of surface activation with 3-(trimethoxysilyl) propyl methacrylate (TSPA), followed by free-radical graft polymerization of methacrylic acid (MAA) in ethyl acetate with 2,2′-azobisisobutyronitrile (AIBN) initiator. The composition of the composites hybrid materials was determined by FTIR spectroscopy. Equilibrium swelling studies were carried out in enzyme-free simulated gastric and intestinal fluids (SGF and SIF, respectively). The dried composites were immersed in a saturated solution of 5-ASA in water overnight and dried over a period of three days at room temperature and the in vitro release profiles were established separately in both (SGF, pH 1) and (SIF, pH 7.4). The 5-ASA concentration of the solution was measured using a UV-Vis spectrophotometer (205 nm) at different time intervals. The in vitro drug release test revealed that the release rate of 5-ASA in buffer solutions increased with the silica content in the composites; on the contrary, the increase of the content of 3-(trimethoxysilyl)propyl methacrylate (TSPA), a coupling agent, decreased the drug release rate.

Abstract
Many environmental conditions can influence the mechanical characteristics of the glucose-sensitive hydrogels. In this paper, a multi-effect-coupling glucose-stimulus (MECglu) model is developed to study the influence of environmental solution pH on the swelling behavior of soft smart hydrogels responding to change in surrounding blood glucose concentration. In order to characterize the chemo-electro-mechanical behaviors of the hydrogels, the model is composed of the Nernst-Planck type of diffusion-reaction partial differential equations for mobile species with consideration of the enzyme reaction catalyzed by the glucose oxidase and the catalase, the Poisson equation for electric potential, and the nonlinear equilibrium equation for mechanical large deformation of the glucose-sensitive hydrogel. In the MECglu model, the formulation of the fixed charge groups bound onto the corsslinked polymeric network is associated with the change of the ambient solution pH. Using these nonlinear coupled partial differential equations, we demonstrate that the computational mechanical deformation by the MECglu model consists well with the experimental observations published in the range of practical physiological glucose concentration from 0 to 16.5 mM (300 mg/ml). The simulations are also carried out for analysis of the influences of physiological pH on the distributive profiles of reacting and diffusive species concentrations and the electric potential as well as the mechanical deformation of the glucose-sensitive hydrogels. The simulations by the model can efficiently support the design and optimization of the insulin delivery system based on the glucose-sensitive hydrogels with the immobilized glucose oxidase and catalase.
