Abstract

Nanopraticles can be prepared by several methods and the ionic gelation method is the easiest one. Verapamil hydrochloride is a drug which used as antiarrhythmic, antiangina, and antihypertension therapy. Nevertheless, bioavailability of orally administered verapamil is very low, only about 10 to 23%. Therefore, verapamil hydrochloride was prepared as nanoparticles dosage form to increase its  bioavailability. The purpose of the present study was to optimize ionic gelation method of chitosan and sodium tripolyphosphate to obtain the best nanoparticles formulation. Nanoparticles were obtained from four different methods (formula A, B, C and D). Particle size distribution, zeta potential, entrapment efficiency, morphology, and fourier transform infra red spectrum of each nanoparticles formula were characterized. The chosen formula was formula D which has 62.8 nm of size, 59.15% of entrapment efficiency, ±25.46 mV of zeta potential, spherical shape, and the ionic interaction was confirmed by FT-IR spectrum. The result showed that chitosan-tripolyphosphate succesfully produce the verapamil hydrochloride nanoparticles by ionic gelation method.Keywords: chitosan, ionic gelation, nanoparticles, sodium tripolyphosphate, verapamil hydrochloride

Abstract

Colon-Targeted Drug Delivery System (CTDDS) is able to improve local therapeutic effects in the treatment of colon-specific diseases, such as Crohn’s disease, Ulcerative Colitis (UC), and Irritable Bowel Syndrome (IBS). A colon can also be a suitable site for systemic delivery of drugs susceptible to extreme gastric pH, such as peptides and protein therapeutics. The physiological conditions of the gastrointestinal tract and the physicochemical properties of drugs are being considered to develop strategies and approaches to overcome emerging challenges. This review will discuss factors, challenges, strategies, and approaches to developing a colon-targeted drug delivery system.

Abstract

Encapsulation was a promising method for protecting probiotics from extreme conditions during their passage through the gastrointestinal tract and delivering probiotics to specific sites in the colon for colonization. Various dosage forms have been used in recent years to encapsulate probiotics to maintain cell viability during processing, storage, and through the digestive tract to provide health benefits. However, research related to the encapsulation of probiotics as the dosage forms for colon-targeted delivery systems was still quite limited to conventional dosage forms due to the sensitivity of probiotics to extreme conditions during the process. This review focuses on various types of dosage forms that are used in colon-targeted delivery systems for commonly used probiotic bacteria. In this review, we discussed the limitations of the current dosage forms used in probiotic encapsulation, along with the latest advancements in colon-targeted delivery systems for probiotic products. This review also covers future perspectives on the potential dosage forms that can effectively maintain probiotic viability and provide specific release in the colon.

Abstract

Oral colon-targeted drug delivery systems represent a significant advancement offering both systemic and local therapeutic effects for a range of intestinal diseases, including irritable bowel syndrome, inflammatory bowel disease, colonic bacterial infections, and colorectal cancer. These systems facilitate the delivery of both small molecules and macromolecular compounds such as peptides, proteins, antibodies, oligonucleotides, RNA, and probiotics. This review provides an up-to-date exploration of the critical factors crucial for the effective design and development of drug delivery systems targeting the colon. The chosen strategy takes into account various aspects of colon physiology that influences the profile of drug release, absorption, dissolution, and stability in the colon, including pH, retention time, presence of enzymes, pressure, presence of reactive oxygen species due to inflammation, and specific receptors. Site-targeted drug release allows for high concentrations in the colon while minimizing systemic adverse effects by reducing or preventing drug absorption in the small intestine.

Abstract

Gastroretentive Mucoadhesive Dosage Form (GMDF) is one type of Gastroretentive Drug Delivery System (GRDDS) technology designed to exploit the adhesiveness of dosage forms in the gastric mucosa. This aims to increase drug residence time, enhance drug solubility and absorption, and ultimately improve drug bioavailability and therapeutic effect. Various studies have explored the use of different polymers to develop GMDF systems and dosage forms. However, despite extensive research in this field, there are still limited GMDF products approved by the US FDA and INA FDA. Therefore, this review addresses the challenges in developing GMDF, its current state, and potential future opportunities. This literature review is performed by searching Google Scholar, PubMed, and ScienceDirect and Google Patents using the terms “gastroretentive”, “mucoadhesive”, “challenge”, “strategy”, and “patent.” Additionally, searches were conducted in the US FDA and INA FDA Drug Approval Databases. Based on our study, we identified numerous challenges in developing GMDF, including patient physiological challenges, drug formulas, production processes, product analysis, and clinical trials. To address these challenges, multiple strategies should be developed to optimize the formulation, production process, and product analysis of GMDF, ultimately leading to successful clinical trials and regulatory approval of this product.

Abstract

Inflammatory Bowel Disease (IBD) is a chronic inflammatory condition in the colon that includes ulcerative colitis and Crohn’s disease. Dexamethasone is a steroid anti-inflammatory drug that can be used in IBD therapy. This study aims to obtain an optimum formulation of a dexamethasone drug delivery system for IBD treatment and to investigate its release profile based on an in vitro dissolution test. Dexamethasone was formulated as a double-coated tablet in combination with a probiotic L. acidophilus and B. longum mixture (1:1). The core tablets were produced using the wet granulation method, after which they were coated with pectin 4% b/v on the inner coat and a mixture of Eudragit L100 and S100 (1:4) on the outer coat. Three different core tablet formulas were prepared by varying the concentration of probiotics at 0%, 16% and 40% (F1, F2, and F3, respectively). The cumulative drug release of F1, F2 and F3 in HCl 0.1 N pH 1.2 for 2 hours were 42.92 ± 1.55%, 39.41 ± 4.10%, and 39.39 ± 1.63%, respectively, while in the phosphate buffer pH 6.8 they were 102.83 ± 1.56%, 105.08 ± 1.70%, and 98.81 ± 3.37% respectively, after 12 hours. From the results, we conclude that all formulas could be promising candidates for developing colon-targeted drug delivery.

Abstract

Ambroxol HCl is a mucolytic agent often used to treat respiratory disorders associated with excess mucus secretion. This study aims to determine the beyond-use date (BUD) of ambroxol HCl syrup on the market based on analysis of the decrease in drug content using High-Performance Liquid Chromatography (HPLC) – UV/Vis detector. The HPLC conditions were reversed-phase with a C18 column, mobile phase containing acetonitrile - phosphate buffer 0.05 M pH 4.5 (60:40) at a flow rate of 1.0 ml/min using UV detection at 248 nm. To determine BUD, five syrup preparations (brands) obtained from the Jakarta area were analyzed in triplicate. The retention time for ambroxol HCl was 4.62 minutes. In the validation, ambroxol HCl showed good linearity with r = 0.99985 in the 6 to 36 µg/ml. LOD and LOQ for ambroxol HCl were 0.74 µg/ml and 2.25 µg/ml, respectively. It is also fulfilled the accuracy and precision parameters with a % recovery from 99.04% to 100.94% and CV<2%. This method meets the requirements according to the ICH Q2(R1) guidelines and can be used for the assay of ambroxol HCl syrup. The ambroxol HCl level on all samples was still higher than 90% (until the 36th day). Normality test data result indicated that data must be divided into two groups that are sample A and B, and sample C, D, and E. In conclusion, the extrapolation result showed that the BUD ambroxol HCl syrup was 83 days for sample A and B, and 49 days for sample C, D, and E.
