    ABSTRACT
    Solving solubility problems is a major challenge for the pharmaceutical industry with developments of new pharmaceutical products, since nearly half of the active substances being identified are either insoluble or poorly soluble in water soluble. Various techniques are used for the enhancement of the solubility of poorly soluble drugs which include Liquisolid technique, micronization, nanonization, sonocrystallization, supercritical fluid method, spray freezing into liquid and lyophilization, evaporative precipitation into aqueous solution, use of surfactant, use of co-solvent, hydrotropy method, use of salt forms, solvent deposition, solubilizing agents, modification of the crystal habit, co-crystallisation, complexation and drug dispersion in carriers.The “Liquisolid” technique is a novel and capable addition towards such an aims for solubility enhancement and dissolution improvement, thereby it increases the bioavailability.Liquisolid technique is based upon the admixture of drug loaded solutions with appropriate carrier and coating materials. The use of non-volatile solvent causes improved wettability and ensures molecular dispersion of drug in the formulation and leads to enhance solubility. By using hydrophobic carriers (non-volatile solvents) one can sustained the release of drugs by this technique. Liquisolid compacts demonstrated a considerably higher drug dissolution rates than those of conventionally made capsules and directly compressed tablets. This was due to the increased wetting properties and surface of drug available for dissolution. By using this technique, solubility and dissolution rate of water insoluble drugs can be improved. This review paper highlights the advantages, disadvantages, mechanism of enhanced drug release, classification, evaluation and application of liquisolid technique to enhance the solubility and dissolution of water insoluble drugs.

    ABSTRACT:
    Liquid chromatography is a fundamental separation technique in the life sciences and related fields of chemistry. Unlike gas chromatography, which is unsuitable for nonvolatile and thermally fragile molecules, liquid chromatography can safely separate a very wide range of organic compounds, from small-molecule drug metabolites to peptides and proteins. Traditional detectors for liquid chromatography include refractive index, electrochemical, fluorescence, and ultraviolet-visible (UV-Vis) detectors. Some of these generate two- dimensional data; that is, data representing signal strength as a function of time. Others, including fluorescence and diode- array UV-Vis detectors, generate three-dimensional data. Three-dimensional data include not only signal strength but spectral data for each point in time. Mass spectrometers also generate three- dimensional data. In addition to signal strength, they generate mass spectral data that can provide valuable information about the molecular weight, structure, identity, quantity, and purity of a sample. Mass spectral data add specificity that increases confidence in the results of both qualitative and quantitative analyses. For most compounds, a mass spectrometer is more sensitive and far more specific than all other LC detectors. It can analyze compounds that lack a suitable chromophore. It can also identify components in unresolved chromatographic peaks, reducing the need for perfect chromatography. Mass spectral data complements data from other LC detectors. While two compounds may have similar UV spectra or similar mass spectra, it is uncommon for them to have both. The two orthogonal sets of data can be used to confidently identify, confirm, and quantify compounds.

    ABSTRACT:
    A group of Australian researchers at the Garvan Institute in Sydney have conducted a study indicating how Grb10 protein plays a crucial role in increasing muscle mass during development. Growth factor receptor-bound protein 10 also known as insulin receptor-binding protein Grb-IR is a protein that in humans is encoded by the GRB10 gene. The product of this gene belongs to a small family of adapter proteins that are known to interact with a number of receptor tyrosine kinases and signaling molecules. This gene encodes a growth factor receptor-binding protein that interacts with insulin and insulin-like growth-factor receptors (e.g., IGF1R and IGF2R). Over expression of some isoforms of the encoded protein inhibits tyrosine kinase activity and results in growth suppression. This gene is imprinted in a highly isoform- and tissue-specific manner. Alternatively spliced transcript variants encoding different isoforms have been identified.Scientists have discovered a way to build bigger and stronger muscles without having to lift a finger.

    ABSTRACT:
    Now a day about 74% of drugs are taken orally and are found not to be as effective as desired either due to bioavailability problems or degradation of drug in acidic pH of stomach. To resolve such problems, transdermal drug delivery system (TDDS) was emerged. Transdermal drug delivery systems are dosage forms involves drug transport to viable epidermal and dermal tissues of the skin for local therapeutic effect while a very major fraction of drug is transported into the systemic blood circulation. Transdermal drug delivery systems, also known as ‘‘patches,’’ are dosage forms designed to deliver a therapeutically effective amount of drug across a patient’s skin. This review article provides an overview of TDDS, advantages, limitations, various components of TDDS, methods of preparation, types of transdermal patches, factors affecting transdermal permeation, evaluation parameters and new approaches in TDDS.

    1. INTRODUCTION:-
    1.1. Origin:-

    Contract manufacturing is defined as the manufacture (or partial manufacturer) of a product to the order of one person or organization (the contract giver or customer) by another independent person or organization (contract acceptor or principle manufacturer). Manufacture in this context is identified as the act of processing or packaging a medicinal product or device to a given specification.(Shah, D.H., 2000)

    Contract manufacturing should be consideration as an extension of the principal manufacturer’s operation. Consequently the principal manufacturer should require the same standards of good manufacturing practices (GMP) for a contractor’s operation as he would his own. In addition, the customer must ensure that the principle manufacturer holds the relevant legal authorizations for the work to be carried out.(Shah, D.H., 2000)

    The responsibility and activities undertaken by each party need to be clearly stated in a formal agreement, separate from but additional to the legal business contract formed by the placement of an order. Commercial matters need to be appreciated as being distinct from technical matter and need to be detailed separately with due consideration for compliance with local legislation.(Shah, D.H., 2000)

    ABSTRACT
    The basic rationale of sustained release drug delivery system optimizes the biopharmaceutical, pharmacokinetic and pharmacodynamic properties of a drug in such a way that its utility is maximized, side-effects are reduced and cure of the disease is achieved. There are several advantages of sustained release drug delivery over conventional dosage forms like improved patient compliance due to less frequent drug administration, maximum utilization of the drug, increased safety margin of potent drug, reduction of fluctuation in steady-state drug levels, reduction in healthcare costs through improved therapy and shorter treatment period.Presently pharmaceutical industries are focusing on development of sustained release formulations due to its inherent boons.Wide varieties of polymers are available for retarding the release rate of drugs hence sustains the action of drugs. This article contains the basic information regarding sustained-release formulation, its advantages, different types, and characteristics involved in oral sustained-release dosage form design.

    ABSTRACT:
    Prior studies have suggested that depressed people with evidence of high inflammation are less likely to respond to traditional treatments for the disorder, including anti-depressant medications and psychotherapy. This study was designed to see whether blocking inflammation would be a useful treatment for either a wide range of people with difficult-to-treat depression or only those with high levels of inflammation. The study employed infliximab, one of the new biologic drugs used to treat autoimmune and inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease. A biologic drug copies the effects of substances naturally made by the body's immune system. In this case, the drug was an antibody that blocks tumour necrosis factor (TNF), a key molecule in inflammation that has been shown to be elevated in some depressed individuals. Study participants all had major depression and were moderately resistant to conventional antidepressant treatment. Each participant was assigned either to infliximab or to a non-active placebo treatment. When investigators looked at the results for the group as a whole, no significant differences were found in the improvement of depression symptoms between the drug and placebo groups. However, when the subjects with high inflammation were examined separately, they exhibited a much better response to infliximab than to placebo.
