The present study was aimed to isolate and characterize mucilage obtained from the leaves of Amaltas (Cassia fistula) and to check the binding efficiency by comparing with gum acacia. Isolation of mucilage was done by hot maceration process and investigated for various physicochemical characterization and in vitro dissolution profile to check mucilage as a binding agent. Different batches (KF1 – KF4) of paracetamol tablets of different concentration of mucilage (3%, 5%, 10% and 15% w/v) were prepared by wet granulation method. All the parameters of uncoated tablets were performed and compared with tablets prepared with gum acacia in the same concentration. SEM indicated irregular shape and size of mucilage particles. Good thermal stability of mucilage was indicated by TGA and amorphous nature by P-XRD and DSC. FTIR and NMR confirmed the presence of polysaccharide. From the results, formulations KF2 and KF3 were found to be optimized as they showed 99% drug release within 20-25 min and better results were obtained when compared with existing binder gum acacia. According to the studies, mucilage isolated from the leaves of Cassia fistula showed interesting results suggesting that amaltas mucilage can be used as a promising natural excipient (binder) in preparation of conventional uncoated tablet dosage form.

The main objective of the study was to enhance the dissolution of nifedipine, a poorly water soluble drug by betacyclodextrin complexation and to study the effect of the preparation method on the in vitro dissolution profile. The stoichiometric ratio determined by phase solubility analysis for inclusion complexation of nifedipine with β-cyclodextrin was 1:1. Binary complex was prepared by different methods and was further characterized using XRD, DSC and FT-IR. A saturation solubility study was carried out to evaluate the increase in solubility of nifedipine. The optimized complex was formulated into fast-dissolving tablets by using the superdisintegrants Doshion P544, pregelatinized starch, crospovidone, sodium starch glycolate and croscarmellose sodium by direct compression. Tablets were evaluated for friability, hardness, weight variation, disintegration and in vitro dissolution. Tablets showed an enhanced dissolution rate compared to pure nifedipine.

Rosuvastatin (RVT) is a BCS class II antilipidemic crystalline drug, which exhibits low bioavailability due to its very poor aqueous solubility; therefore, it is challenging to develop a proper formulation of RVT. To enhance solubility and bioavailability of this API, an attempt has been made by implementing solid dispersion technique. Solid dispersion (SD) technique is a solubility enhancing technique where one or more active entities are dispersed in an inert medium (matrix or carrier) at solid state. In this study, different ratios of Kollicoat® IR (KIR) and Kollidon® 90F (KF90) polymers were used with API to prepare various formulations by physical mixing (PM) and SD approaches; here solvent evaporation technique was used whereas methanol was used as solvent which was completely evaporated from the homogenously dispersed system by placing in a water-bath at 60-65°C and then in oven for 30 minutes at 50 °C. Among the formulations, RVT-KF90 SD formulations showed the most promising result in in-vitro study in terms of drug release profile (78.04 – 99.21%) in comparison to pure RVT (63.1%) and physical mixing of RVT with those polymers. USP dissolution apparatus type II was used at 37°C ± 0.5°C with 50 rpm to conduct the in-vitro experiment. The experiment also unraveled that the dissolution of RVT improved with increasing the amounts of polymers. Subsequently, stability of the developed formulations was conducted by Fourier transforms infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) as well as scanning electron microscopy (SEM). The results obtained from FTIR ensured no involvement of any significant drug-excipient interaction. Moreover, the DSC study signified thermal stability at high temperature. Besides, the SEM micrograph illustrated homogenous distribution of RVT in the polymer and transformation of crystal-like RVT into amorphous formulations. Dhaka Univ. J. Pharm.

The aim of the present work was to develop immediate release dosage form of the solid dispersion of glimperide (GLIM) for potential enhancement in the bioavailability. The solid dispersions of GLIM were prepared with PEG6000, PVP K30 and Poloxamer 188, in 1:1, 1:3 and 1:5 %w/w ratio by using solvent wetting and solvent melt method. The in vitro dissolution parameters (%DE10min, %DE30min, %DE60min, T50% and DP30) were used to select the optimized solid dispersion that was characterized by IR, PXRD, DSC and SEM. The optimized solid dispersion of GLIM (GSDSM3) was used as drug component for immediate release (IR) tablets that were evaluated for physical and pharmacopoeial parameters. The in vitro drug release studies identified G4 as the optimized tablet with a cumulative drug release (CDR) of 99.34% in 30 min in phosphate buffer, pH 7.4. The CDR was higher than the marketed tablet (91.15%, Amaryl®, Sanofiaventis), However, the f1 and f2 were 10.6 and 52 respectively, which confirmed similarity of the dissolution profile(s). Accelerated stability studies confirmed stability up to 6 months at 40°C/75% condition in the HDPE bottle pack.

The purpose of the study was to evaluate cassia roxburghii seed gum powder as binder for paracetamol and diclofenac sodium. Granules of both drugs were prepared by wet granulation method. Two different laboratory developed methods were tried for the isolation of seed mucilage from seed powder. The phytochemical, physico-chemical and microbiological properties were performed on the seed gum and the pre-compression parameters like bulk density, tapped density, angle of repose, carr’s index and hausner’s ratio have shown that paracetamol and diclofenac granules prepared using Cassia roxburghii gum were well within the limits and comparable to those prepared using standard starch paste as binder. The in vitro dissolution study was performed for paracetamol formulations with sodium starch glycolate and the dissolution profile shows all the three formulations met with official specifications. The in vitro dissolution profile shows that drug release decreased in the order, tablets prepared by starch>c.roxburghii defatted>c.roxburghii filtered in both paracetamol and diclofenac formulations. The drug release from tablets prepared by C.roxburghii seed gum was more than 85% in 2 hours and filtered C.roxburghii gum has excellent mechanical, binding and release properties in paracetamol tablet formulations with the addition of sodium starch glycolate as an external disintegrant
