Isothermal heat conduction microcalorimetry was used to evaluate chemical stability of a solid drug in tablets. A variety of mixtures were compressed to flat faced tablets of 300 mg weight and 10 mm diameter. The content of drug amounted to 10%. Besides drug containing tablets, also placebo tablets as well as the non compressed mixtures were examined by microcalorimetry at 80 degrees C. The exc...

For increased analgesic effect, new composed tablets containing diclofenac sodium (DIC) with an addition of papaverine hydrochloride (PAP) were prepared to investigate the mechanism of release of the active substances from tablets with different excipients in eight different formulations. To detect the possible interactions between active substances and excipients differential scanning calorime...

The aim of present study was to improve the solubility of pioglitazone HCl a practically insoluble antidiabetic drug by using liquisolid technique. The in vitro release pattern of liquisolid tablets and directly compressed tablets were studied using USP-II apparatus. Different Liquisolid tablets were prepared using a mathematical model to calculate the required quantities of powder and liquid i...

An endeavor has been made to create buccoadhesive bilayered tablets comprising of drug containing bioadhesive layer and drug free backing layer to release the drug for extended period of time with reduction in dosing recurrence. Tablets of Tizanidine hydrochloride were prepared by direct compression method using bioadhesive polymer tamarind seed gum with backing layer of ethyl cellulose. The ph...

BACKGROUND Orodispersible tablets or fast dissolving tablets dissolve or disintegrate immediately on the patients' tongue or buccal mucosa. This drug delivery system is suitable for drugs undergoing high first pass metabolism. It improves bioavailability, reduces dosing frequency, and thereby minimizes the side effects and also makes the dosage form more cost-effective. In this study, polysacch...

The pharmacopoeial quality of non-expired and expired nifedipine tablets of the same batches purchased from the Estonian and Russian Federation medicinal product markets was evaluated. The IR spectroscopy, HPLC analysis for quantitative content and purity of the active pharmaceutical ingredient (API), and dissolution test techniques were applied. In the experiments with non-expired nifedipine t...

The purpose of this study was to determine the in vivo glycemic index of carob tablets with healthy subjects and to determine the in vitro glycemic index of carob tablets and carob flour by the hydrolysis index. Seven healthy volunteers consumed portions of carob tablets containing 26g of available carbohydrate. Their capillary blood was taken at intervals after carob or glucose consumption. Th...

This study aimed to research the preparation and content determination of capsaicin-chitosan microspheres (CCMS) enteric coated tablets. The core tablets were prepared with the method of wet granulation. Nine formulae were designed to determine the optimal formula of the core tablet. Eudragit L100 was used to prepare the CCMS enteric-coated tablets. The effect of enteric coated formulation vari...

The aim of this study was to evaluate the influence of disintegration mechanism of various types of disintegrants on the absorption ratio (AR), wetting time (WT), and disintegration time (DT) of orodispersible tablets (ODTs). ODTs were prepared by direct compression using mannitol as filler and disintegrants selected from a range of swellable, osmotic, and porous disintegrants. Tablets formed w...

25 The use of fused-filament 3D printing (FF 3DP) to fabricate individual tablets is 26 demonstrated. The technology permits the manufacture of tablets containing drug 27 doses tailored to individual patients, or to fabrication of tablets with specific drug-28 release profiles. Commercially produced polyvinyl alcohol (PVA) filament was loaded 29 with a model drug (Fluorescein) by swelling of th...
