Abstract

Cimetidine is an H2 receptor antagonist which can be used to reduce acid secretion in the stomach by inhibiting selective binding of histamine to H2 receptors so that it can reduce the concentration of cyclic-adenosine monophosphate (c-AMP) which plays a role in the proton pump mechanism. The combination of floating and mucoadhesive systems is used to increase drug retention in the stomach so that it can reduce the drug interval and increase bioavailability of the drug. The purpose of this study was to make floating-mucoadhesive cimetidine tablets using Hydroxypropyl Methylcellulose (HPMC) as a floating polymer and chitosan as a mucoadhesive polymer. Tablets are expected to have the ability to maintain the dosage form in the stomach for approximately 12 hours. The evaluations carried out included the flow characteristics and the angle repose of the powder mixture, tablet weight uniformity, tablet hardness, tablet friability, floating lag time, floating duration time and tablet mucoadhesive strength. The responses observed were the ability to float and the mucoadhesive strength of tablets. The tablet release test (dissolution) for the optimum formula was performed to determine the character of tablet release. The optimum amount for HPMC is 146,686 mg and chitosan are 50 mg. The combination of polymers with this amount produces a floating lag time of 43,458 seconds, floating duration time >12 hours and the strength of mucoadhesive is 100 grams. The release of the optimum formula in the 720th minute is about 73,180% following the Higuchi release model with dissolution efficiency (DE720) about 67,855%.

Abstract

Piroxicam, a non steroidal anti inflammatory drugs (NSAID), is an oxicam derivative which can be used for treatment of various rheumatic diseases, such as rheumatoid arthritis and osteoarthritis. Piroxicam patch is an affective approach evading piroxicam?s side effect such as peptic ulcer and first pass metabolism. One of the patch components is polymer that the function is to control the speed of drug release from the patch. The aims of this study were to determine the optimum formula of a combination of polyvinylpyrolidone (PVP) and Carbopol to % moisture content (MC) and the flux release in solid dispersion piroxicam patch using Simplex Lattice Design. Piroxicam was prepared in the form of a solid dispersion in PEG 4000 to increase its solubility. The design formula of solid dispersion piroxicam patch made with the ratio PVP : Carbopol, that were 1 : 0; 0.5 : 0.5; 0 : 1. The optimum formula was chosen with the ratio PVP : Carbopol, 1: 0, which gave the best result of % MC and flux release. The result of % MC was 6.91% and the result of flux release was 35.543 µg/cm2.menit1/2.

Abstract

This research aims is to create a promethazine HCl patch transdermal drug delivery systems with the most excellent penetration. Transdermal drug delivery can be efficiently used for the active agents which undergo rapid first pass metabolism and oral absorption is often disrupted by nausea and vomiting, hence the transdermal patches of promethazine HCl were prepared by using different penetration enhancers,  propylene glycol, oleic acid and isopropyl alcohol. The prepared formulations were evaluated for thickness, weight variation, moisture content, drug content, morphology, and in vitro permeation studies. The patch morphology studies were performed by Scanning Electron Microscopy (SEM). The amount of promethazine HCl transfered by propylene glycol  25.77 ± 3.0396 ug, isopropil alcohol 25.758 ± 2.9022 ug and oleic acid 25.017 ± 8.1300 ug. The penetration of promethazine HCl patch with oleic acid enhancer, produce the highest penetration than isopropil alcohol and propylene glycol. there was no difference in penetration using propylene glycol and isopropyl alcohol. Oleic acid is the best enhancer for preparations patch containing promethazine HCl although the amount of promethazine HCl contained is the least. The whole formulations comply with the  patch dosage requirements

Abstract

ABSTRACT This study aims to determine the effect of using gelling agent and chemical penetration enhancer on the solid dispersion Ibuprofen gel in increasing the transdermal drug penetration. Inhibition of the COX-1 enzyme caused by ibuprofen in oral administration can cause side effects of gastrointestinal disorders, dyspepsia, diarrhea, upper gastrointestinal infections, nausea and bloating, resulting in a topical route to reduce side effects. The gel is prepared using hydroxy propyl methyl cellulose (HPMC) and carbopol® as gelling agents, and also propylene glycol and glycerin as chemical penetration enhancer compounds. The gel evaluation are viscosity, pH, spreadability and penetration flux rate. The value of the formula 3 penetration flux is 1.5383 ± 0.029 ug / cm2.minute, the formula 1 is 1.403 ± 0.055 ug / cm2. minute, the formula 2 is 0.756 ± 0.071 ug / cm2 minute, while the formula 4 is 0.5404 ± 0.106 ug / Cm2. minute. The amount of gelling agent concentration and chemical penetration enhancer compound effect on the value of the flux penetration
