Pregabalin is BCS class I drug. It is 3rd generation anticonvulsant used in epilepsy in which faster action is required. Nasal route has faster action than oral route, also convenient to unconscious patient. Pregabalin loaded in situ gel, for the treatment of epilepsy to avoid side effects and first pass metabolism associated with conventional treatment and increase bioavailability. Pregabalin was loaded into different polymeric solutions of Polycarbophil and HPMC K4M. The drug was characterized for various parameters like UV-Spectroscopy, FTIR Spectroscopy and DSC study. Excipients were screened for selection of mucoadhesive and gelling polymer. Then the drug was formulated as in situ gel. The experiment was subjected to 32 full factorial design, the concentration of Polycarbophil (X1) and HPMC K4M (X2) were selected as independent variables with % drug release and muco-adhesive strength as dependent variables. The kinetic study was carried out for 30 days. Polycarbophil was selected as mucoadhesive and gelling polymer. The values for X1 and X2 were 0.3922% and 0.5263% relating the % drug release and mucoadhesive strength values were 78.20% CDR at 240 min. and 960 dynes/cm2 respectively for checkpoint batch following zero order and Higuchi kinetic. The formulation was found to be stable for 30 days. The present research will be helpful in order to improve the efficacy and tolerability of the antiepileptic drug therapy. So alternative administration strategy has been investigated which deliver nasally administered medication directly to brain effectively. The intranasal in situ gelling system is a promising novel drug delivery system for an antiepileptic drug Pregabalin which could enhance nasal residence time with increased viscosity and mucoadhesive character and provided better release profile of drug for treating epileptic conditions.  ","PeriodicalId":14382,"journal":{"name":"International Journal of Pharmaceutical Sciences and Nanotechnology","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79989804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study is to formulate oral disintegrating tablets of salbutamol sulphate to achieve rapid dissolution, absorption and further improving the bioavailability of the drug. Oral disintegrating tablets of salbutamol sulphate were designed with a view to enhance the patient compliance and provide a quick onset of action. The oral disintegrating tablets were prepared by using different synthetic polymers by direct compression method. Development of the formulation in the present study was based on the concentration of superdisintegrants and the properties of the drug. Nine batches of tablets were formulated and evaluated for various parameters: drug content, weight variation, water absorption ratio, wetting time, in vitro disintegration, hardness, friability, thickness uniformity, and in vitro dissolution. A fourier-transform infrared spectroscopy (FTIR) study showed that there were no significant interactions between the drug and the excipients. The prepared tablets were good in appearance and showed acceptable results for hardness and friability. The in vitro disintegrating time of the formulated tablets was found to be 14.39-32.41 sec and the drug content of tablets in all formulations was found to be between 87.48-99.96 %, which complied within the limits established in the Indian pharmacopeia. The study concluded that taste of the drug was masked with the help of sodium saccarhin, flavor and the concentration of super disintegrating agent increases the disintegration time of tablets get decreases.

The present work includes isolation of starch from Echinochloa Colona and further characterizing it for various physicochemical and phytochemical analysis. The isolated starch has been modified chemically and its disintegrating efficiency has been tested in tablet formulation; the present work also explores the optimization of concentration of starch in formulation of Ibuprofen tablets in comparison with synthetic and natural superdisintegrants. Phytochemical analysis confirmed the presence of starches and carbohydrates. Results indicated that the Echinochloa Colona starch samples could be potential superdisintegrants in orally disintegrating tablets of Ibuprofen. Tablet performance was found to influence by the way of addition of starch, its concentration and the method of tablet preparation.

Drug delivered to lung through inhalation will provide systemic and local drug delivery at lower dose in chronic and acute diseases. Dry powder inhalers are the best choice for targeting the anti-asthmatic drugs through pulmonary route. The objective of the present study is to prepare inhalable lipid coated budesonide microparticles by spray drying method so effective delivery of budesonide to the lungs can be achieved. The microparticles in the form of dry powder were obtained by either spray drying liposomal drug suspension or lipid drug suspension. The liposomes were initially prepared by solvent evaporation method using Hydrogenated Soyabean Phosphatidylcholine and Cholesterol (1:1, 1:2, 2:1) as lipid carrier and then spray dried later with mannitol as bulking agent at different lipid to diluent ratio (1:1.25, 1:2.5 & 1:5). The liposomes and liposomal dry powder were evaluated for vesicle size, % entrapment efficiency, in vitro drug release studies, powder characteristics, aerosol performance and stability studies. The liposomes prepared showed vesicle size (2-8 µm), Entrapment efficiency (92.22%) at lipid: drug ratio of (2.5:1) and observed 80.41 % drug release in 24 hrs. Pro-liposomes prepared by spray drying of liposomal drug suspension (LSD1) showed emitted dose, mean mass aerodynamic diameter, geometric standard deviation and fine particle fraction of 99.01%, 3.12 µm, 1.78 and 43.5% along with good powder properties. The spray dried powder was found to be stable at 4 ± 2 °C & 65% ± 5 % RH. The inhalable microparticles containing Budesonide containing lipid dry powder was successfully prepared by spray drying method that showed good aerodynamic properties and stability with mannitol as diluent. The microparticles produced with this novel approach could deliver drug on target via inhalation route and also ease manufacture process at large scale in fewer production steps.","PeriodicalId":14382,"journal":{"name":"International Journal of Pharmaceutical Sciences and Nanotechnology","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90872430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The disease is considered as a potential global health threat by world health organization due to its high emerging deaths. Coronaviruses are transmitted by respiratory aerosols producing mild upper respiratory infections. Currently, no vaccine or specific COVID-19 inhibitors are available for treatment except repurposed drugs. The COVID-19 virus genome has ~30,000 nucleotides. Its replicase gene encodes overlapping polyproteins necessary for viral replication and transcription. Recently COVID-19 main protease was successfully crystallized and made available in Protein Data Bank for public use. Several studies report medicinal plants to have antiviral bioactivities. Application of in silico computer‐based docking studies involving small molecules could be time saving for irrelevant in vivo models. In the present study, we have investigated 500 natural compounds from different plants having antiviral properties. We have also screened several protease inhibitors and other repurposed drugs claimed to be active against COVID-19.  The docking was performed on Autodock vina, using grid size 22, 22, 24 along the X, Y, and Z axes with 1.000 A˚ spacing. The docked positions in binding pockets were visualized using Discovery studio 3.5 software.  Most of the repurposed protease inhibitors were having good binding energy, saquinavir being the most potent. Among natural compounds, jervine and isoacteoside were found to be having good binding with protease protein. It was observed that flavonoid was the commonest chemical group amongst most potent natural compounds. The amino acids Thr26, Asn142, Gly143, Ser144, Cys145, His163, and Glu166 showed strong H-bond interactions with docked compounds. The conclusion of the recent study will help researchers to identify the better drug to battle COVID-19. To be brief, our findings emphasize a promising pharmaceutical perspective for targeting main protease of novel coronavirus. However further preclinical and clinical trials should be carried out to validate these potential compounds.","PeriodicalId":14382,"journal":{"name":"International Journal of Pharmaceutical Sciences and Nanotechnology","volume":"76 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81125357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
