Fast Disintegrating Tablets

An attempt was made to prepare fast dissolving tablets of anti-inflammatory drug Nimesulide preparing by direct compression method. The superdisintegrants Cross-carmellose and Sodium starch glycolate were used in different concentrations. Twelve formulations using those superdisintegrants at different concentration levels were prepared to access their efficiency and critical concentration level. Different evaluation parameters for tablet were studied. Tablets containing Cross-carmellose showed superior organoleptic properties and excellent in-vitro drug release as compared to other formulations. It was observed that on increasing the concentration of Cross-carmellose, the rate of disintegration was increased whereas on increasing the concentration of Sodium starch glycolate the rate of disintegration was decreased. The percentage drug release was observed as 96.32% when the concentration of Cross-carmellose was increased, whereas the same was not observed on increasing the concentration of Sodium starch glycolate.

Mouth Dissolving Tablet

In the current investigations, mouth dissolving tablets (MDT) were developed by applying quality by design (QbD) approach. Direct compression method was applied for the preparation of MDT containing aspirin using 32 factorial design with quantity of drug, microcrystalline cellulose (MCC) and crosscarmellose sodium (CCS) as dependant variables. MCC and CCS were used as superdisintegrants. Sodium stearyl fumarate was used as lubricant. Developed MDT were evaluated for characteristics like hardness, friability, disintegration time (DT) and in vitro drug release . Design Expert 11.0 described adequately impact of selected variables (MCC and CCS) at various levels for response under study (DT and friability). The optimized batch showed disintegration time of 15-28 secs, friability within 1% and in vitro drug release of 75-98% after 30 mins, respectively. The present study of experimental design revealed that MCC and CCS are fruitful at low concentration to develop the optimized formulation. As per the results obtained from the experiments, it can be concluded that QbD is an effective and efficient approach for the development of quality into MDT with the application of QTPP, risk assessment and critical quality attributes (CQA).

Objective: The aim of this study was to develop a bioadhesive gel of gatifloxacin for the treatment of periodontal diseases.Methods: Periodontal gels of gatifloxacin were prepared using different hydrophilic polymers such as carbopol 940 (CP 940), carboxymethyl cellulose (CMC) and hydroxypropylmethyl cellulose (HPMC) in varied concentrations, either alone or as a combination. The prepared gels were evaluated for their physical appearance, pH, drug content, viscosity, bioadhesiveness and in vitro drug release profile. The influence of the type and the concentration of polymer on the drug release as well as on viscosity and mucoadhesiveness of prepared gels were investigated.Results: The prepared gels showed acceptable physical properties concerning color, homogeneity, consistency, spreadability, and pH value. Using different polymer types at different concentrations, as well as different polymer combinations, play a significant role in the variation of overall characteristics of formulations. Increasing the concentration of polymer increased the viscosity as well as mucoadhesion, and reduced drug release rate. Formulation F 11 (1 % CP 940 and 5 % CMC) was selected as the formula of choice based on the data of various evaluation parameters such as pH, drug content, viscosity, spreadability and bioadhesion as well as its ability to show a prolonged drug release pattern.Conclusion: The obtained results show that a bioadhesive periodontal gel of gatifloxacin can be prepared using hydrophilic polymers, and by using a combination of polymers the viscosity, mucoadhesiveness, spreadability and release behavior can be optimized.

Transdermal patch is a drug delivery device in which the drugs are incorporated and is design in such a way that it releases the drug in sustained and at predetermined rate to deliver the drug through the skin to the systemic circulation painlessly. The aim of this research study was to formulate a controlled and sustained release transdermal matrix type patch of Methimazole. The matrix patch was prepared by solvent casting method using a various polymer in different concentration, HPMC (hydrophilic), Eudragit RL100 and Ethyl cellulose (hydrophobic) polymer. Total 9 prototype formulation were prepared and it was subjected for various evaluation test; weight uniformity, Folding endurance, thickness, Drug content, percent moisture content, percent Moisture uptake and In-vitro drug release study using Franz diffusion cell. The in-vitro CDR% data was fit into kinetics model to see the release kinetics from the patches. The Formulation F5 was choosen as a best formulation according to in-vitro drug release study. The in-vitro release was found 81.12 % in 12 hours, it followed zero order kinetics. The nature of polymer and concentration ratio of polymers plays a crucial role for obtaining a good transdermal patch design; therefore optimisation is very important step to formulate a desired TDDS. Therefore the result of the study encourages a further study and is hopeful that the present study would contribute to the recent pharmaceutical research for formulation development.

The present work was aimed to develop a transferosomal gel of ibuprofen (IBU) for the amelioration of psoriasis like inflammation. Three formulation of IBU loaded transferosomes (TFs1-TFs3) were prepared using different proportions of lipid (phospholipon 90H) and surfactant (tween 80) and further evaluated for vesicle size, zeta potential (ZP), entrapment efficiency and in vitro drug release. The IBU loaded transferosomes (TFs2) was optimized with vesicle size (217±8.4 nm), PDI (0.102), ZP (-31.5±4.3 mV), entrapment efficiency (88.4±6.9%) and drug loading (44.2±2.9%). Further, the optimized IBU loaded transferosomes (TFs2) was incorporated into 1% carbopol 934 gel base and characterized for homogeneity, extrudability, viscosity and drug content. The in vivo pharmacodynamic study of gel exhibited reduction in psoriasis like inflammation in mice. The ibuprofen loaded transferosomal gel was successfully developed and has shown the potential to be a new therapy against psoriasis like inflammation.

Objective: The main purpose of this study is to prepare a floating micro articulated drug delivery system of ciprofloxacin by using non-aqueous solvent evaporation technique to increase the bioavailability and therapeutic effectiveness of the drug by prolonging its gastric residence time.Methods: Floating microparticles were prepared by using different low-density polymers such as ethyl cellulose and hydroxypropyl methylcellulose either alone or in combination with the aid of non-aqueous solvent evaporation technique. All the formulated microparticles were subjected to various evaluation parameters such as percentage yield, drug content, drug entrapment, rheological studies, floating characteristics and in vitro drug release studies.Results: Drug-excipient compatibility studies performed with the help of FTIR instrument indicated that there were no interactions. Results revealed that non-aqueous solvent evaporation technique is a suitable technique for the preparation of floating microspheres as most of the formulations were discrete and spherical in shape with a good yield of 65% to 85% and 15 to 22 h of floating duration with 90% of maximum percentage floating capacity shown by formulation FM9. Though, different drug-polymer ratios, as well as a combination of polymers, play a significant role in the variation of overall characteristics of formulations. Based on the data of various evaluation parameters such as particle size analysis, drug content, drug entrapment, rheological studies and in vitro drug release characteristics formulation FM9 was found to fulfil the criteria of ideal floating drug delivery system.Conclusion: Floating microparticles were successfully prepared, and from this study, it can be concluded that the developed floating microspheres of ciprofloxacin can be used for prolonged drug release in the stomach to improve the bioavailability and patient compliance.
