The SLNs, comprising glycerol mono stearate (GMS) as a solid lipid core, Brij 35 used as surfactant and PEGylated phospholipid used as stabilizer, were prepared using a hot homogenization method. Optimized PTX-EMB loaded formulation, the particle sizes of the prepared SLNs were around 300 nm, suggesting that they would be suitable as a parenteral formulation. Transmission electron microscopy showed that the SLNs were homogeneous and spherical in shape. Entrapment efficiency of paclitaxel and embelin was 92.83 ± 2.2%, 83.25 ± 2.4% respectively. An <em>in vitro</em> drug release study were performed in PBS (pH 7.4) for 80 hrs and observed that paclitaxel and embelin released from the PEGylated SLNs was 93.91 ± 4.1 % and 75.63 ± 4.37 % respectively. Furthermore, treatment of the MCF-7 breast cancer cell line with PTX-EMB loaded SLNs yielded cytotoxicities comparable to PTX solution, PTX-EMB mixture solution and PTX loaded PEGylated SLNs.

Cubosomes are thermodynamically stable and consist of honeycombed (cavernous) structures separating two internal aqueous channels and a large interfacial area. Cubosomes are nanoparticles which are self assembled liquid crystalline particles of certain surfactants with proper ratio of water with microstructure that provides unique properties of practical interest. Bicontinuous cubic liquid crystalline phase is optically clear and very viscous material has the unique structure at nanometer scale. The word bicontinuous refers to the division of the two continuous but non-intersecting aqueous regions by lipid bilayer that is twisted into space filling structure. Hydrating a surfactant or polar lipid that forms cubic phase and then dispersing a solid like phase into smaller particles usually forms a cubosomes. Self-assembled cubosomes as active drug delivery systems are receiving more and more attention and interest after the first discovery and nomination. They exhibit different internal cubic structure and composition with different drug-loading modalities. It has high internal surface area and cubic crystalline structures, relatively simple preparation method, biodegradability of lipids, the ability of encapsulating hydrophobic, hydrophilic and amphiphilic substances, targeting and controlled release of bioactive agents. Cubosomes are having wide range of applications in various fields and they can be characterized by various evaluation parameters.

The inclusion criteria of the study i.e : patients with stroke, was a original papers with observational study, concerned on AF in stroke patients in southeast Asia. Data on incidence and prevalence were obtained from hospital-based studies and community-based studies.</p> <p><strong>Results</strong>: Atrial Fibrillation prevalence data are available in five countries in southeast Asia, a total of the 11 articles identified were from Malaysia, Thailand, Vietnam, Singapore, and Indonesia were also represented. The reported prevalence of AF as a risk factor of stroke patients was 2.6 % until 23.04% based on hospital-based studies.</p> <p><strong>Conclusion:</strong> AF is one of risk factors that associated with the stroke. This study also showed that prevalence AF in South East Asia ranged&nbsp; 2.6 – 23.04 % . However, owing to the limited number of studies in southeast Asian countries, further investigation is needed before drawing a definite true of prevalence of AF in the southeast Asia population.</p> <p><strong>Keywords: </strong>Atrial Fibrillation, AF-associated Stroke, Epidemiology, Risk Factors.</p> 2020-01-15T00:00:00-06:00 ##submission.copyrightStatement## http://jddtonline.info/index.php/jddt/article/view/3830 Tirosyne Kinase Inhibithors (TKIs) in the Treatment of Non –Small Cell Lung Cancer (NSCLC), Practical Pharmacological Aspects 2020-01-15T02:29:30-06:00 Alexandru C.

For Non-Small Cell Lung Cancer this drug brought more hope for patients with this disease. Also TKIs are better tolerated then chemotherapy. The efficacy of TKIs is dependent of the presence of Epidermal Grows Factor Receptor gene mutation. This mutation account for about 9% of patients with lung cancer in Europe. This short review try to give the minimal knowledge to clinicians, especially medical oncologists, about mechanism of action, pharmacokinetics of TKIs used in the treatment NSCLC.</h2> <p><strong>Keywords:</strong> Tyrosine Kinase Inhibitors (TKI); Non -Small Cell Lung Cancer; Pharmacokinetics aspects</p> 2020-01-15T00:00:00-06:00 ##submission.copyrightStatement## http://jddtonline.info/index.php/jddt/article/view/3803 Current Approaches on Gastroretentive Drug Delivery systems 2020-01-15T02:29:30-06:00 Aniket Uttam Pund aniketpund97@gmail.com Raosaheb Sopanrao Shendge shendgerajan@gmail.com Ajinkya Kailas Pote ajinkyapote1996@gmail.com <p>Over recent years, there have been many efforts to develop the absorption rate of medications and the therapeutic efficacy of oral dosage types. GRDDS for strengthen the pharmacological effects of drugs with a small uptake site, are unbalanced at pH greater than 7, are dissolved under acidic region, and are effective local region in the stomach. The gastro retentive systems that have the different evaluation parameter that according to the dosage forms. There are many criteria for the choosing of the drug used in the gastro-retardant systems as the drug should be sparingly stable, it should be compatible with the gastric region, and narrow absorption. In this review, we have summarized the information related to the various approaches for enhancing and prolonging of the dosage forms in the stomach for their extended-release of action. Also talking about the many natural and synthetic polymers is used in the formulation with their different grade and their ratio that affects on the release action. The many scientist and inventors have increased their interest in developing the novel dosage forms and they staying in the stomach for showing the prolonged period action. We have also discussed the novel technology are involved in the gastric retention many companies has been developed the polymer grades for using it in the formulation for showing the retention action.</p> <p><strong>Keywords: </strong>Introduction, Approaches, Novel technologies, Polymer used in floating systems.</p> 2020-01-15T00:00:00-06:00 ##submission.copyrightStatement## http://jddtonline.info/index.php/jddt/article/view/3838 Advanced technologies in the modern era for augmented patient health care and drug delivery 2020-01-15T02:29:30-06:00 Asish Dev asishdev@gmail.com Soma Khanra somakhanra14@gmail.com Nilay Shah asishdev@gmail.com <p>The objective of the work is to recognize the recent advancements in the modern health care and drug delivery systems.

Natural products are usually believed to be safer, cheaper, easily available and sometimes more efficacious than purely synthetic drugs. Diabetes mellitus is a major health problem in the world. There is no cure for diabetes. With the increase in a number of newer drugs for diabetes, there is the possibility of a wide range of side effects that vary from one drug to another.&nbsp; It is, therefore, essential to practice effective methods of the treatment and management of diabetes. Hence, the need to explore antidiabetic drugs of natural origin with minimal side effects is highly essential. This review provides a scientific perspective on the usage and research of natural traditional remedies in the management of diabetes. The aim of the present review is to provide a comprehensive and concise overview of the previously reported clinical trials of antioxidative natural products in the management of diabetes.</p> <p><strong>Keywords: </strong>Diabetes, Natural products, Hyperglycemia, Diabetic complications,</p> 2020-01-15T00:00:00-06:00 ##submission.copyrightStatement## http://jddtonline.info/index.php/jddt/article/view/3865 Psychotic Disorders, Definition, Sign and Symptoms, Antipsychotic Drugs, Mechanism of Action, Pharmacokinetics & Pharmacodynamics with Side Effects & Adverse Drug Reactions: Updated Systematic Review Article 2020-01-15T02:29:30-06:00 Rohit Bangwal rohitbangwal93@gmail.com Shivam Bisht rohitbangwal93@gmail.com Saurabh Saklani rohitbangwal93@gmail.com Shobit Garg rohitbangwal93@gmail.com Mohan Dhayani rohitbangwal93@gmail.com <p>Psychosis is a mental disorder characterized by a disconnection from reality. Psychosis is a group of disorder characterized by thought disorder, abnormal behaviour, defective cognition, delusion and hallucination. Adverse drug reaction is defined as any undesired or unintended effects of drugs treatment. According to the World Health Organization (WHO)- “adverse drug reaction (ADRs) has been defined one which is noxious and unintended, and which occurs at doses normally used in man for prophylaxis, diagnosis, or therapy of disease, or modification of physiological function”. Adverse drug reactions are the most important causes of the mortality and morbidity. Antipsychotics are the most effective drugs which are used in the psychiatry in the maintenance therapy of mania, psychoses and schizophrenia. The antipsychotics drugs are chemically disparate but have the common property of alleviating the symptoms of organic as well as functional psychosis. But they also have a capacity to cause a wide range of potential adverse drug reactions that can lead to non-compliance that can impair quality of life, may cause the extra pyramidal symptoms which can lead to discontinuation of therapy and in extreme cases it may be fatal. Knowledge of assessment of ADRs due to different antipsychotics is necessary. It helps to choose to safe treatment and reduce the risk of occurrence of ADRs by the clinicians. ADR are often poorly identified and reported in day to day medical practice. As we collect more and more information about ADRs, we need an active surveillance system regarding identification and reporting of ADRs with antipsychotic drugs.&nbsp; On many review articles are read &amp; ward round participation experiences we find that antipsychotic drugs can have shown a various kind of ADRs. Psychiatrist and clinical pharmacist are need to be made aware of these potentially fatal adverse effects associated with antipsychotic drugs via conduction of patients counseling regarding (drugs, disease, doses &amp; side effects), quality-based seminars, published medical literature, conferences, learning programs and health care camps.</p> <p><strong>Keywords</strong>: Antipsychotic Drugs, WHO, Adverse Drug Reactions, Pharmacovigilance, Psychiatrist.</p> 2020-01-15T00:00:00-06:00 ##submission.copyrightStatement##
