Hugonia mystax Linn., is an ethanobotanically important plant which plays a vital role in primary healthcare of tribals from Tiruvannamalai hills, Tamil Nadu, India. There is paucity in the literature regarding the active phytoconstituents of H. mystax contributing to the biological activities claimed by traditional healers. Therefore, the present investigation aims to analyze the metabolite profile of leaf extracts of H. mystax. Quantitative determination of total phenolic and flavonoid of leaves was carried out. The highest amount of phenolic and flavonoid was found in ethanol extracts of the leaves. RP-HPLC analysis of individual phenolic compounds revealed the presence of Gallic acid, Catechol, Caffeic acid, Vanillin, p-Coumaric acid and Ferulic acid. Catechol was found to be the highest in water extract. GC-MS of chloroform fraction and LC-MS of methanol/water fraction led to the identification of 19 and 21 compounds respectively. Chloroform fraction revealed the presence of 1-Hexanol (37.69%), Cinnamene (13.81%) and p-Xylol (9.39%), whereas, methanol/water fraction revealed the presence of p-Myrcene (19.5%), 4-Vinyphenol (12.72%) and p-Vinylguaiacol (4-VG) (7.82%) respectively as the major compounds. This is the very first report of metabolite analysis of leaves of H. mystax L. from south-west region of India. This investigation identified the major phytoconstituents predominantly present in leaves, which may probably be responsible for the traditional claims of its therapeutic properties.

Pharmacognostic standardization including physico-chemical evaluation is meant for identification, authentication, and detection of adulteration and also compilation of quality control standards of crude drugs. Standardization of herbal drugs has traditionally been based on appearance and today microscopic evaluation is indispensable in the initial identification of herbs, as well as in identifying small fragments of crude or powdered herbs and detection of foreign matter and adulterants. Therefore the present study is to investigate the macroscopical, microscopical, and physico-chemical characteristics of the plant of Breynia Retusa (Dennst). (Family - Euphorbiaceae). The results obtained from the study may play a major role in setting particular standards for the plant of Breynia Retusa (Dennst).

The marketed dry powder inhalations (DPI) are based on lactose monohydrate alone and lactose anhydrous is neither studied nor used as a carrier in marketed DPIs. Lactose is not recommended as a carrier in budesonide formulations since lactose interacts with amine functional group. This study was carried out to investigate the effect of lactose anhydrous inhalation grade 40 M on the aerosolisation performance of budesonide. The work was also aimed at study of an interaction between budesonide and the lactose carriers in dry state. The powder properties of binary formulations, consisting of lactose anhydrous LA 40M and budesonide, were compared with those of lactose monohydrate LM 40 M and budesonide. In vitro drug release was determined with diffusion cell. Based on the results of the preliminary study, two promising formulations F1 and F2 were subjected to the in vitro deposition study using Twin Stage Impinger and Lupihaler®. The results revealed absence of chemical reaction between budesonide and both the grades of lactose namely, LM and LA. Hence lactose can be used as a carrier in budesonide dry powder formulations. The aerosolisation performance of DPIs, consisting of either lactose monohydrate 40M or lactose anhydrous 40M, was similar. The particle size distribution, particle density, morphology, surface roughness, flowability and moisture content of lactose carriers played a complex role in determining fine respirable fraction of budesonide. The in vitro deposition profile of budesonide was improved significantly when budesonide was blended with LM 40M or LA 40M in 1:45 ratio.

Although a number of drugs are available in the market, thrust for discovery of new antimicrobial drugs with better pharmacokinetic profile, and lesser toxicity has become necessary in the field of medicinal chemistry due to fast development of microbial resistance towards the existing molecules. The 2(1H) quinolinone, often referred to as carbostyril moiety, is an important structural unit present in many biologically active molecules. Quinolone antibiotics have gained wide acceptance for the treatment of various bacterial infections. Their mode of action is believed to involve inhibition of bacterial DNA gyrase, an enzyme essential for DNA replication. Many natural and synthetic products containing heterocyclic rings such as pyrazoles, pyrazolones, and isoxazolidines and pyrazolidinediones were reported to possess varied pharmacological activities. Research on 2-quinolone and pyrazolidine 3,5-dione and their synthetic analogs have revealed to possess various pharmacological activities along with wide range of antimicrobial activity. It is our interest to synthesize some new 2-quinolones containing pyrazolidinedione moiety and evaluate their antimicrobial activity.

We provide an insight to the troubles in the field of pharmacy. Using the published literature to date, we review the impact of various challenges in the field of Pharmacy. The pharmaceutical industry has succumbed to the challenges presented by the consumer, other healthcare fields, policies, emergence of telemedicine, sunken research inputs, low drug approval, diminished new drug release in the market, demolishing new drug acceptance and utility. These factors have provided considerable damage to the pharmaceutical industry which can be explicated by the languishing market growth. The consumer aimed advertising meant for profit has the patients educated about branded drugs and also has mislead them to drug abuse. The misled and educated patients have deteriorated the market of generic drugs. The conflict in the marketing of NMEs, Biologics and Biosimilars creates yet another hurdle. The growth of approval of new drugs compared to the year 2016 was just 3% this year. The non-revising policies do not tend to improve the profit of the drug manufacturers but favour the economy of the consumer alone. The industry is spiralling and requires stabilization. We conclude by suggestions by newer reformed policies, better innovations, clear sources of information, thorough pharmacovigilance and well counselled consumers.

The study deals with the comparative evaluation of various extracts of Triticum aestivum (Wheat) grass and Carica papaya (Papaya) leaves by phytochemical screening followed by antioxidant and antihaemolytic activities as revealed by various parameters such as reducing power, nitric oxide (NO) scavenging activity, diphenyl picrylhydrazine (DPPH) free radical scavenging activity, superoxide dismutase assay, H2O2 and hypotonic solution induced haemolysis assay. The phytochemical screening showed high flavonoids, phenolic and alkaloids content which indicates antioxidant strength of the extract. In wheatgrass and papaya leaves n-butanol and aqueous extracts have high scavenging activities compared to ethyl acetate and petroleum ether extracts. All the four extracts (petroleum ether, ethyl acetate, n-butanol, aqueous) scavenge free radicals to a certain extent but n-butanol and aqueous extract exhibited more potential effect among all four extracts. Thus it can be concluded that there two potential extracts could be explored for further in vivo studies.

Introduction: The long term interaction of mobile phone radio-frequency radiation (RFR) on general health, especially on male fertility and repercussion of above is becoming a major concern for current researchers for obvious reasons. Objective of the current study was aimed for evaluating the effect of long term exposure of RFR from mobile phones on blood pressure, hematological parameter, testosterone level, sperm count and their morphology. To perform the current study the RFR generator was used and a uniform radio frequency radiation with frequency range of 900 MHz and 1800 MHz were exposed to the rats placed individually in hexagonal plastic cage which is divided into six compartments. After the experimental period, blood pressure, hematological parameter, testosterone level, sperm count and their morphology were studied .Total sperm count, their morphology, total platelet count were significantly affected at both RFR. BP, neutrophil, lymphocyte percentage were significantly affected at 900 MHz however no significant changes were observed in hemoglobin content, total RBC and WBC count, eosinophil percentage and serum testosterone level.Hence it can be concluded that a long term (12week) mobile phone RFR exposure significantly affected hematological parameter, and had perilous effect on male fertility in rats.

The objective of present study was to document the requirements for manufacturing of semisolid dosage forms. These guidelines also brief about some issues associated with tools, strategies, critical process parameters and strategies of the manufacturing and validation processes specific to semisolid dosage forms. Studies about the effect of manufacturing processes and formulation exipients on the rheology of semisolids have contributed significantly toward their characterization. The development of computer-assisted instruments also has contributed substantially to their characterization and thereby to improving their quality. Variations in the manufacturing procedure that occur after either of these events are likely to be critical to the characteristics of the finished product. This is especially true of any process intended to increase the degree of dispersion through reducing droplet or particle size (e.g., homogenization). Semisolids can adhere to the application surface for sufficiently long periods before they are washed off. This property helps prolong drug delivery at the application site. Novel semisolids are non-greasy since they are made up of water washable bases. Hence they cause less irritation to skin and are superior to conventional semisolid dosage form. The major conclusion drawn from such detailed study of semisolids in –process shortfalls provides a better vision and encounter while designing and developing new formulations.

Nebivolol hydrochloride is a selective ?1- antagonist falls under class II biopharmaceutical classification system. In the present investigation liquisolid compaction approach is applied to improve the dissolution and permeability properties thereby enhancing the oral bioavailability of nebivolol hydrochloride. Different formulations were developed by dissolving the drug in mixture of Transcutol HP & Propylene glycol (Non volatile liquid; 1:1 ratio), converting this liquid medication using fujicalin and neusilin as carriers and syloid FP 244 as coating material. In vitro drug release profiles of liquisolid compacts shown enhanced drug release when compared to pure drug as well as marketed formulation. The plasma concentration-time profile of healthy wister rats indicated that the oral bioavailability of optimized formulation has been significantly improved when compared to pure drug and marketed formulation. Improved bioavailability might be due to increased wetting properties of drug and improved permeability of the drug due to lipophilic properties of solvent used for wetting. From this study we can conclude that liquisolid technique is one of the promising alternative techniques to improve the bioavailability of class II drugs.

Mucoadhesive microspheres were found to be more efficient for controlled drug delivery. Mucoadhesion ensures increased contact time of the dosage form with the absorption site while microspheres sustained the release of drug from the dosage form at the site of absorption and result into improved bioavailability of drug. The present study involves formulation and evaluation of mucoadhesive microspheres of oral hypoglycemic drug, metformin hydrochloride. The microspheres were formulated by emulsification phase separation technique using chitosan as polymer and gluteraldehyde as cross-linking agent. Preformulation studies showed that the compositions are compatible with each other. The formulation batches were prepared by 32 factorial design with two independent parameters, polymer to drug ratio and stirring speed. All the batches were evaluated for particle size, flow properties, mucoadhesion, microencapsulation efficiency, drug release and stability. The formulation MF5 showed nearly spherical microcapsules, good flowability, microencapsulation efficiency, mucoadhesion, stability and extended drug release upto 12 hours. An approach to develop a stable mucoadhesive microspheres of oral hypoglycemic drug, Metformin hydrochloride has been successfully achieved.

During the recent past, several Ayurvedic medicines have been prepared and investigated with respect to physio-chemical standardization, pharmacological effects, safety, efficacy, cultivation of medicinal plants and manufacturing practices. The objectives of this study is suggesting a novel method for the authentication of Ayurvedic and Siddha medicines to ensure the identity, quality, purity and detection of adulterants non-destructively using the spectroscopic techniques. The Ayurvedic sample Trikatu Churna, TC, taken for analysis, is a polyhedral formulation of finely powered dried fruits of Piper nigrum, pn, Piper longum, pl, and rhizome of Zingiber officinale, zn, at equal proportions. The customised TC was prepared by mixing at the equal proportion of the pure and dried raw material component powders (reference sample). The NIR spectral characteristics of customised samples were compared with the market samples (test samples) by developing a suitable Chemometric model. Accordingly, a method is proposed using Principal Component Analysis (PCA) technique to bring out strong patterns from their reference TC spectra to validate test samples by identifying its identity, quality and purity non-destructively.
