He is serving as an Editorial Member of several reputed journals. He has authored more than 50 research articles.
 

Abstract:

Nigella sativa (NS) is black seed with different biological activities and its anti-diabetic effect is one of the highly investigated activities. Streptozotocin-induced diabetic rats (fed with a high-fat diet) were treated daily with NS Oil (NSO) in order to study its anti-liver or brain insulin resistance. In the hepatic tissues, the administration of NSO significantly induced the gene expression of insulin receptor compared to NSO-untreated rats. In addition, it up-regulated the expression of insulin-like growth factor 1 and phosphoinositide-3 kinase. On the other hand, the expression of ADAM-17 was down-regulated, whereas the level of TIMP-3 confirmed its down-regulation. In the brain, it corrected the reduced insulin signaling pathway (p-IRS/ p-AKT/p-GSK-3β) resulted from the stimulation of GSK-3β level. This, in turn, contributed to a decreased Tau phosphorylation along with changes in the protein phosphatase PP2A level. In conclusion, NSO or its combined treatments with anti-diabetic drugs have a possible protective and modifying effect of the insulin resistance through enhancing the hepatic and brain insulin signaling pathway.

Abstract:

Liver diseases are considered as one of the serious health problems, as it is an important organ for the detoxification and deposition of endogenous and exogenous substances. A number of pharmacological and chemical agents act as hepatotoxins and produce a variety of liver ailments. Steroids, vaccines and antiviral drugs which have been employed as a therapy for liver diseases, have potential adverse effects especially when administered for long terms. Traditional healing practices are now wide spread amongst about 80% of the developed countries population and often termed alternative or complementary medicine.

Aim: In the absence of reliable liver-protective drugs in modern medicine, hepatoprotective drugs from plant sources seem to have attractive alternatives. The aim of this scientific lecture is designed to focus in the medicinal plants as well as the other alternative medicines which can be used as hepatoprotective and antihepatotoxic agent.

Medicinal plants that are found in the Arabic Gulf, India and United State of America with scientific researches were discussed.  The active constituents, mechanism of actions, safety, side effects and the contraindication of each plant were discussed as well. Other alternative medicines like aromatherapy, acupuncture therapy, breathing therapy and relaxation therapy were deliberated.

Rakesh S. Shivatare

Title: Novel drug delivery systems : new lifeline for herbal drugs
Speaker
Biography:

Rakesh S. Shivatare has completed his Master in pharmacy (Pharmacognosy) at the age of 24 years from Pune University. He had worked as research officer and having 5 year experience in formulation analytical method development. He has published more than 15 papers in reputed national and international journals.

Abstract:

Novel drug delivery systems (NDDS) are designed to achieve a continuous delivery of drugs at predictable and reproducible kinetics over an extended period of time in the circulation. The potential advantages of this concept include minimisation of drug related side effects due to controlled therapeutic blood levels instead of oscillating blood levels, improved patient compliance due to reduced frequency of dosing and the reduction of the total dose of drug administered.

In the past few decades, considerable attention has been focused on the development of novel drug delivery system for herbal drugs. The novel carriers should ideally fulfill two prerequisites. Firstly, it should deliver the drug at a rate directed by the needs of the body, over the period of treatment. Secondly, it should channel the active entity of herbal drug to the site of action. Conventional dosage forms including prolonged-release dosage forms are unable to meet none of these. In phyto-formulation research, developing nano dosage forms (polymeric nanoparticles and nanocapsules, liposomes, solid lipid nanoparticles, phytosomes and nanoemulsion etc.) have a number of advantages for herbal drugs, including enhancement of solubility and bioavailability, protection from toxicity, enhancement of pharmacological activity, enhancement of stability, improving tissue macrophages distribution, sustained delivery, protection from physical and chemical degradation etc.

Thus the nano-sized novel drug delivery systems of herbal drugs have a potential future for enhancing the activity and overcoming problems associated with plant medicines.

Abstract:

About 80% of world population use herbal products in one time of their lifetime therefore, research become more oriented and focused on the evaluation of safety and quality control of commercially marketed herbal products. In advanced researches it has been documented that plants contain not only beneficial minerals, secondary metabolites but also contain non-essential minerals, toxic elements as they are contaminated with environmental pollutants specially heavy metals. Thirty one over the counter herbal products that are available within the UAE pharmaceutical markets were investigated for the presence of seven heavy metals; Cd, Pb, Fe, As, Ni, Al and Hg and to determine whether or not they pose a risk of heavy metal toxicity in regards to World Health Organization (WHO) levels. Sample solution was prepared by a dry ashing or wet digestion procedure. All metals were analyzed either by Graphite Furnace or Flame Atomic Absorption Spectrometry. Method validation was performed by evaluating metal recovery studies and within-day precision studies. The studied samples of herbal products exhibited positive response for all heavy metals except Hg. The results were compared with established WHO permissible limits as for Provisional Tolerable Daily Intake for Pb is 0.02 to 3μg/kg BW (body weight), for Fe is 0.8mg/kg BW and for Ni is 12μg/kg BW; Weekly Intake for Hg is 1μg/kg BW, for Al is 1mg/kg BW and for As is 15μg/kg BW; and Monthly Intake for Cd is 25μg/kg BW respectively. In conclusion, the herbal products available within UAE contained tolerable levels of toxic heavy metals except Al and Fe for some products.

Abstract:

One of the successes for CNS drugs is to penetrate the Blood-Brain Barrier (BBB) and achieve the therapeutic targets. Therefore, the rapid screening for potential BBB-penetration of drug candidates provides important information in early drug discovery research. The Parallel Artificial Membrane Permeability Assay (PAMPA) is a high-throughput screening tool applied to predict the passive transport of potential drugs across BBB. It is the non-cell-based in vitro assay often used in pharmaceutical industry which is carried out in a coated 96-well membrane filter. An artificial lipid membrane represented by the polar brain lipid is applied on a hydrophobic filter and the compounds are screened according to their pass from a Donor (D) compartment through the filter to an Acceptor (A) part. Subsequently, A and D wells are analyzed by LC/MS or in UV-Vis spectrophotometer. The assessed concentrations are then used for calculation of the permeability coefficient (Pe). Compounds with Pe lower than 2.0×10-6 cm.s-1 were classified as potentially non-BBB permeable (CNS-) and compounds with Pe higher than 4.0×10-6 cm.s-1 were recognized as potentially BBB permeable (CNS+). Of course, the assay can predict the CNS bioavailability based on the passive diffusion and active transport as well as efflux mechanisms are not considered. In the study, we correlated PAMPA-obtained permeability of some drugs (e.g. donepezil, rivastigmine, tacrine, testosterone, furosemide, sulfasalazine) and the results were compared with the real values mentioned in the literature.

Title: Inventing formula for drug development and analytical techniques is the key for pharmaceutical industries
Speaker
Biography:

Rakesh S. Shivatare has completed his Master in pharmacy (Pharmacognosy) at the age of 24 years from Pune University. He had worked as research officer and having 5 year experience in formulation analytical method development. He has published more than 15 papers in reputed national and international journals.            

Abstract:

The pharmaceutical industry is essentially defined by innovation. Research on the forefront of science, the creation of new knowledge bases, the invention of new medicines, and the improvement of existing drugs constitute the fuel that propels the firms in this industry.

Formulation can be categorized according to the route of administration. Pharmaceutical development information provides the scientific rationale for formulation development and justification for a suitable dosage form. Excipients are the major fraction of the solid dosage forms which serve as diluents to allow the formulation of appropriately sized tablets and coatings to protect the tablet from undesirable organoleptic qualities of the drug substance. Solid state reactions in the dosage form can occur when the drug substance is reactive and may be accelerated by physical and chemical interaction with excipients.

In the field of pharmaceutical research, the analytical investigation of bulk drug materials, intermediates, drug products, drug formulations, impurities and degradation products, and biological samples containing the drugs and their metabolites is very important. From the commencement of official pharmaceutical analysis, analytical assay methods were included in the compendial monographs with the aim to characterize the quality of bulk drug materials by setting limits of their active ingredient content. In recent years, the assay methods in the monographs include titrimetry, spectrometry, chromatography, and capillary electrophoresis; also the electro analytical methods can be seen in the literature.

Abstract:

Diclofenac sodium (DS) is a non-steroidal anti-inflammatory drug that has a bitter taste with local irritation to stomach. The aim of this research is to formulate taste masked DS orally dispersible tablets (ODTs) with drug release in the intestine. Pellets of DS were designed using sugar sphere cores layered with DS followed by enteric coat of Eudragit L100 and then a second coat of Eudragit E100 for taste masking. The produced pellets had high loading efficiency of 99.52 % with diameters ranged from 493.7 to 638.9 μm. Pellets were spherical with smooth surfaces as examined by SEM. Pellets with 12 % enteric coated Eudragit L100 followed by 5% Eudragit E 100 showed 1.4±0.5% DS release in simulated gastric fluid (SGF) while completely dissoluted in simulated intestinal fluid (SIF). The pellets were used for formulation of ODTs. In vitro disintegration times of ODTs ranged between 20±0.26 and 46±0.27 sec in simulated saliva fluid (SSF). While, dissolution was less than 10% in SGF and all drug was released in SIF. The release rate was higher for the promising formulation (F12) in SIF compared with the marketed product voltaren® 25 mg. The optimized ODTs formulation had smoothness with highly acceptable taste.
