    Abstract
    Drug targeting is the ability to direct a therapeutic agent specifically to desired site of action with little or no interaction with nontarget tissue. Niosomes are one of the best carriers for drug targeting. Niosomes (non-ionic surfactant vesicles) are microscopic lamellar structures formed on admixture of non-ionic surfactant of the alkyl or dialkyl polyglycerol ether class and cholesterol with subsequent hydration in aqueous media. Niosomes are biodegradable, relatively nontoxic, more stable and inexpensive, an alternative to liposomes. Niosomes can be SUV (Small Unilamellar Vesicles), MLV (Multilamellr Vesicles) or LUV (Large Unilamellar Vesicles). The method of preparation of niosome is the based on liposome technology. The basic process of preparation is the same i.e. hydration of the lipid phase by aqueous phase. After preparing niosomal dispersion, unentrapped drug is separated by dialysis, centrifugation or gel filtration. Niosomes are characterized by vesicle size, bilayer formation, number of lamellae, membrane rigidity and entrapment efficiency. A method of in-vitro release rate study includes the use of dialysis tubing. Niosomal drug delivery is potentially applicable to many pharmacological agents for their action against various diseases including cancer and leishmaniasis.

    Abstract:
    Inconvenience of administration and patient compliance are gaining significant importance in the design of dosage forms. Difficulty in swallowing (dysphagia) is common among all age groups, especially in elderly and pediatrics. Ciprofloxacin hydrochloride is an orally administered antibacterial agent. The objective of this study was to develop ciprofloxacin hydrochloride soft gel using sodium alginate as a gelling agent and sodium citrate as a source of cation. Gels are formed by aggregation of polymers with minimum two components; the gelling agent and the fluid component.  Different batches were prepared using three different concentrations of sodium alginate (0.1, 0.4, and 0.8%). The consistency of sodium alginate gel was dependent on the concentration of, sodium alginate, sodium citrate and co-solute. The results of dissolution study of soft gel F3 containing 0.4% sodium alginate and 0.3% sodium citrate revealed that Ciprofloxacin hydrochloride was 85% released in 45 min. and possessed acceptable sensory characteristics when evaluated by human volunteers. Short term stability study carried out for four weeks at different temperatures (0°C and room temperature) showed no considerable changes in performance characteristics of developed optimized formulation.

    Abstract:
    Neuropathic pain represents a real clinical challenge because of its severity, chronic nature, and inadequate drug therapy. Recently, nitric oxide pathway has been proposed in the pathogenesis neuropathic pain like conditions. Curcumin is a well known for its antioxidant and medicinal values. The objective of the present study was to explore possible nitric oxide mechanism in the protective effect of curcumin against sciatic nerve ligation induced behavioral and biochemical alterations in rats.Sciatic nerve ligation was performed in Wistar rats. Various behavioral parameters (thermal hyperalgesia, cold allodynia) followed by assessment of biochemical parameters (lipid peroxidation, reduced glutathione, catalase, and nitrite) both on sciatic nerves and brain. Sciatic nerve ligation significantly caused thermal hyeralgesia, cold allodynia and oxidative damage as compared to sham (Sciatic nerve without ligation) and naïve animals. Chronic administration of curcumin (20 mg/kg, po) significantly reversed behavioral alteration and attenuated oxidative damage in both sciatic nerve and brain as compared to control.  Further, L-NAME (5 mg/kg) pretreatment with curcumin (10 mg/kg, po) potentiated protective effect of curcumin as compared to their effect per se. However, L-arginine (100 mg/kg) pretreatment with curcumin (10 mg/kg, po) significantly reversed the protective effects of curcumin. Result of present study suggests that nitric oxide mechanism could be involved in the protective effect of curcumin against sciatic nerve ligation induced behavior and biochemical alterations in rats.

    ABSTRACT
    Benfotiamine (rINN, or S-benzoylthiamine O-monophoshate) is a synthetic S-acyl derivative of thiamine (vitamin B1). It has potential anti oxidant effect. A three-armed, randomized, multicentre, placebo-controlled double-blind study was used to examine the efficacy of benfotiamine vs a combination containing benfotiamine and vitamins B6 and B12 in out-patients with severe symptoms of alcoholic polyneuropathy (Benfotiamine in treatment of Alcoholic Polyneuropathy. BAP I). The study period was 8 weeks and 84 patients fulfilled all the prerequisite criteria and completed the study as planned. Benfotiamine led to significant improvement of alcoholic polyneuropathy. Vibration perception (measured at the tip of the great toe) significantly improved in the course of the study, as did motor function, and the overall score reflecting the entire range of symptoms of alcoholic polyneuropathy. A tendency toward improvement was evident for pain and co-ordination, no therapy-specific adverse effects were seen.

  • RECENT TRENDS IN INSULIN DRUG DELIVERY SYSTEM

    Abstract:
    The demand for novel drug delivery technologies is ever increasing. These drug delivery technologies includes oral, transdermal, inhalation and parenteral. The main goal for the delivery of any drug therapy is oral administration with once or twice daily dosing. However, there are large numbers of therapies, particularly protein-based, gene-based vaccine-based that cannot be delivered by this route for example insulin, growth hormones and other similar biologicals.
    The pitfalls of needle-based injections are well known. Psychological resistances to self-injection or needle-phobia have been documented across large demographic groups, such as diabetics. The result of this phobia is that many outpatient injectables are dosed sub-optimally. Furthermore, awareness of serious problems has caused physicians and their patients to either delay therapy initiation or seek out less-invasive alternatives, even at some cost to clinical effectiveness.
    For some, especially those suffering from chronic diseases requiring injectable products two or three times a day, this process is an ongoing reality of daily life for example diabetics-accepted, but always with the hope that something new will replace the ritual of needle insertion. To overcome the problems related to needle based injections, there is one technology that has received considerable attention during the past few years and that offers all of the sought after benefits is—Needle Free Injection Technology (NFIT).

    ABSTRACT
    A simple method for the estimation of Olmesartan in bulk and pharmaceutical dosage forms has been developed. Methanol was chosen as the solvent system. The λmax was found to be 257nm and all absorbance values were carried out at 257nm. The responses were linear in the range of 5-35µg/ml. The regression equation of the calibration graph and correlation coefficient were found to be y = 0.049x + 0.007 and 0.999 respectively. The %RSD values for both intraday and interday precision were less than 1%. The recovery of the drug from the sample was ranged between 99.36 and 100.49%. The proposed method was validated for precision, accuracy, intraday, interday assay, robustness and ruggedness. Commercial tablets containing 20mg and 40mg of Olmesartan were analyzed by the proposed method and the results were well within the claimed limits. Furthermore stability studies of Olmesartan were carried out under acidic, alkaline, hydrolytic and photolytic conditions as per SIAM (Stability Indicating Assay Methods).
