Streszczenie:

Mucoadhesive tablets of montelukast sodium were prepared in order to release the drug for a prolonged period of time so as to reduce the frequency of administration. Direct compression technique was applied using the mucoadhesive polymers which were Methocel K4M CR, Methocel K15M CR, Methocel K100M CR and Eudragit RLPO. Highest percent release of drug after 8 hours was 76% for Methocel K4M CR, 72.13% for Methocel K15M CR, 65.68% for Methocel K100M CR, 65.53% for the combination of Methocel K15M CR and Eudragit RLPO.

Introduction: Cefadroxil is a first-generation cephalosporin and is very effective against Gram positive and Gram negative infections. Cefadroxil is an antibiotic agent which has high absorption in the upper part of the gastrointestinal tract (GIT). Conventional Cefadroxil tablets produce rapid and relatively high peak blood level and require frequent administration to keep the plasma drug level at an effective range. The present study was carried out with an objective of preparation and in vivo evaluation of floating tablets of using Cefadroxil as a model drug using Eudragit polymers to impro

Breast cancer continues to be a significant global health concern, prompting the development of advanced drug delivery systems to improve therapeutic effectiveness and minimize adverse effects. Lipid-polymer hybrid nanoparticles (LPHNPs) offer a promising approach by combining the benefits of both liposomes and polymeric nanoparticles, thereby improving drug solubility, bioavailability, and controlled release. This study aimed to develop and optimize Orlistat-loaded LPHNPs (ORL-LPHNPs) using soya lecithin, Eudragit RLPO, and Tween 80 via nanoprecipitation. Various formulations (LPHNP1-LPHNP8)

Candesartan cilexetil (CC) is an angiotensin II-receptor blocker (ARB). The antihypertensive effect of CC 4-16 mg/day was as great as that of other once-daily dosage regimens. Candesartan cilexetil has high first-pass metabolism and low oral bioavailability. The bioavailability of such drugs may be significantly improved if delivered through the buccal route; hence mucosal delivery is one of the alternative methods of systemic drug delivery. This study’s objective was to develop mucoadhesive buccal tablets of candesartan cilexetil using carbopol-934P, hydroxyl propyl methyl cellulose (HPMC), E

Periodontitis is a serious gum disease that damages the soft tissue and destroys the bone that supports the teeth. According to WHO, globally 1520% of middle-aged (35-44 years) adults, suffer from severe periodontal (gum) diseases. Metronidazole benzoate is an antibacterial agent prescribed against different diseases including, periodontitis and several other protozoal infestations. The aim of this experiment was to formulate intrapocket periodontal patches of metronidazole benzoate to provide site specific therapeutic activity with very small loading dose.

Febuxostat is a selective inhibitor of xanthine oxidase and belongs to BCS class II drugs having low solubility and high permeability. Solubility is the most important parameter which directly affects dissolution, absorption and bioavailability of the drugs. There are different techniques by which we can improve solubility and dissolution rate of poorly soluble drug. Amorphous solid dispersion is one of the methods which can improve solubility as well as powder characteristics. The aim of the present study was to formulate and optimize various methods of formulating solid dispersion by using v

Objectives: Paclitaxel is a cytotoxic drug having wonderful mechanism against cancer cells. However, it showed severe dose-limiting toxicity when administered as infusion. To overcome these side effects a suitable delivery system is highly desirable. Bioenhancers, when mixed with drugs promote and augment their bioavailability and reduced incidence of drug resistance and risk of adverse drug reaction. Therefore, we selected nanoparticles as a delivery system in this study. The object of this work was to entrap paclitaxel and herbal bioenhancer in a nanoparticle system. Materials and methods: W
