    Abstract
    Transdermal drug technology specialists are continuing to search for new methods that can effectively and painlessly deliver larger molecules in therapeutic quantities to overcome the difficulties associated with the oral route, namely poor bioavailability due to hepatic metabolism (first pass) and the tendency to produce rapid blood level spikes (both high and low). As all the drugs do not meet the physicochemical properties required for transdermal drug delivery. So, these techniques are required. Although addition of penetration enhancers increases permeation of drugs but that is not sufficient to ensure delivery of therapeutically effective concentration of drug therefore, several new active rate controlled TDDS technologies (drug and vehicle drug selection, vesicles and particles, Horney layer modified, Horney layer bypassed, Electrically driven and some other techniques) are being employed. This review article covers most of the new active transport technologies involved in enhancing the transdermal permeation into an effective DDS.

    Abstract
    According to the Migraine Research Foundation, migraine ranks in the top 20 of the world’s most disabling medical illnesses with more than 10 percent of the population, including children, suffering from the migraine. Sumatriptan Succinate is a choice of drug used for the treatment of migraine when received at oral dose its bioavailability is approximately 14%. Considering the low bioavailability after oral and intranasal administration, due to presystemic metabolism and incomplete absorption as well as additional inconveniences associated with parenteral and oral administration, the exploitation of an alternative route of sumatriptan delivery, such as transdermal administration (topical gel)—could be sort out mentioned problem and enhance its therapeutic benefit up to most possible extent. Topical delivery systems of Sumatriptan succinate gel were formulated using polymers like HPMC, Carbopol 934 and Pectin and penetration enhancers like eucalyptus oil, menthol and oleic acid. The gels were evaluated for various parameters such as homogeneity, grittiness, extrudability, in vitro drug release, viscosity, pH, spreadability and drug content. The release rate of the gel was found to obey koresmeyer peppas kinetics. It can be concluded that HPMC gel has properties similar to marketed preparation and eucalyptus oil acts as a good penetration enhancer in Sumatriptan gels as compare to menthol and oleic acid.

    SUSPENSION
    Pharmaceutical suspension may be defined as coarse dispersions in which insoluble solids are suspended in a liquid medium. Insoluble solids may have a size range from 10 to 1000 µm.

    STABILITY OF SUSPENSION
    It is important to understand that suspensions are kinetically stable, but thermodynamically unstable, system.
    Physical stability is defined as the condition in which the particles remain uniformly distributed throughout the dispersion without any signs of sedimentation. It is difficult to achieve this condition. Hence the definition can be restated as –if the particles settle they should be easily resuspendable by moderate amount of shaking.

  • Nanotechnology Cure the Uncontrolled Growth of Cells: Cancer

    About Authors: Rinki Verma,

    Banaras Hindu University, Varanasi-221005

    Abstract
    Cancer is caused by damage of genes which control the growth and division of cells. Detection/diagnose/treatment is possible by confirming the growth of the cells and treated by rectifying the damaging mechanism of the genes or by stopping the blood supply to the cells or by destroying it. Conventional detection method of the cancer is not more efficient than nanotechnogical detection method. Nano Particles (NP) being of a few of nano meters size and the cells being of the size of few microns, NP can enter inside the cells and can access the DNA molecules/Genes and therefore, there is a possibility that the defect in the genes can be detected. The conventional treatment is less sensitive than the nanotechnology methods, certain NP can be designed to absorb preferentially certain wave length of radiation and if they enters in the cancerous cells, they will burn them So, Nanotechnology can be used to create therapeutic agents that target specific cells and deliver toxin to kill them.

    Introduction
    From the ancient time it has been the endeavor of the physician and the apothecary to provide patients with the best possible forms of medicine, for recovery from disease faster and completely within minimum adverse effects. Paul Ehrlich in1902 initiated the era of targeted delivery,who proposed drug delivery to be as magic bullet. An ideal drug delivery system is that fulfils the objective of spatial placement and temporal delivery resulting maximized therapeutic effect and least toxicity. With the progress in time and growth of science and technology, the dosage forms have evolved from simple mixtures and pills, to highly sophisticated technology intensive systems, which are known as novel drug delivery systems (NDDS). (1) A different approaches have materialized into various forms of NDDS such as microemulsions, multiple emulsions, liposomes, niosomes, micospheres, pharmacosomes, virosomes, dendrimers, etc.. Most often the problems associated with these delivery systems are their stability and predictability in biological systems which reduce their clinical potential, although each one is associated with its own strong points. Nanotechnology is a rapidly expanding field today. According to the National Nanotechnology Initiative (U.S) nanotechnology is broadly defined as the understanding and control of matter at dimensions of roughly 1 to100 nanometers, where unique phenomena enable novel applications.

    Abstract
    Recent years development in nanotechnology has opened up new horizons in the field of drug and gene delivery. Gold nanoparticles are one of the most versatile platform of nanotechnology. Here the emerging applications of them are discussed. Various approaches like direct drug conjugates, surface modification and light stimulus to achieve desired goals are utilized. Most promising applications of gold nanoparticles is organ targeting. Liver targeting, brain targeting and tumour targeting is achieved precisely with gold nanoparticles. Magnetic targeting in combination with iron nanoparticles can also be achieved with gold nanoparticles. Photodynamic and photothermal therapies for the destruction of tumours is possible with gold nanoparticles due to their unique property, localized surface plasmon resonance (LSPR). Gene delivery is the forthcoming application of gold nanoparticles. DNA can be made available to the site in intact form. Gold Nanoparticles are also used for the management diabetes. Gold nanoparticles are a good carrier for insulin. Gold nanoparticles are popular for the delivery of anticancer agents. New applications are still emerging for delivery of anticancer agents with gold nanoparticles. Due to their unique optical characteristics they are also used in the field of diagnostics. They have therefore been proposed as contrast agents for bioimaging, or as heating devices. Acoustic signals obtained are then utilized. This imaging technique allows recognition of early biochemical, physiological, and anatomical changes before manifestation of gross pathological changes.
