ABSTRACT:
Skin is the main target of topical and transdermal preparations. Major aim of transdermal drug delivery sytem is to cross the stratum corneum. Now-a-days we better know vesicles have importance in cellular communication. Niosomal carrier are systems containing soft vesicles, composed of non –ionic surfactant and an alternative to liposomes. They can entrap both hydrophilic and hydrophobic chemicals but these types of vesicles include the superior physical stability problems such as aggregation, fusion, and leakage of encapsulated drug. Proniosomes are provesicular approach which overcomes the limitations of vesicular system (Niosomes). Provesicular approach has been proposed to enhance the stability of vesicles. Proniosomes is a compact semi-solid liquid crystalline product of non- ionic surfactant  easily formed on dissolving the surfactant in minimal amount of acceptable solvent and the least amount of aqueous phase. Proniosomes can be converted into niosomes in –situ by absorbing water from the skin.

ABSTRCT
Simvastatin is a poorly soluble drug exhibiting poor dissolution pattern. Simvastatin, PEG 6000 & Poloxamer 407 solid dispersions were prepared with a view to study the influence of polymer on solubility and dissolution of this poorly soluble drug Simvastatin. Solid dispersions of Simvastatin were prepared using different ratios of PEG 6000 & Poloxamer 407 as carrier by, solvent evaporation method. They were evaluated for percentage yield, drug content, FTIR spectral studies, DSC, XRD, solubility, and in-vitro dissolution. The solubility profile indicated that there is increase in solubility of Simvastatin when polymer concentration is increased. The solid dispersion complex of drug (1:5:5 ratios) was giving better dissolution profile as compared to pure drug and other solid dispersions. This in turn can improve the bioavailability. FT-IR, DSC shows the compatibility of drug and carrier.

ABSTRACT
In the present scenario, lung cancer is one of the most prevalent and malignant cancer especially among the smoking group of people. The targeted delivery of chemotherapeutic agents to the lungs represents a novel therapeutic approach in lung cancer. Lung is an ideal route for administration of anticancer drug as it provides larger alveolar surface area, low thickness of epithelial barrier & extensive vascularization. Nanoparticles with nanocarriers have possibility of cell-targeted drug delivery with minimal systemic side effect and toxicity. Pulmonary epithelial cell, enzymes, receptors and genes are the target of the targeted drug delivery in lung cancer. This paper reviews the till date targeted drug delivery research performed for the treatment of lung cancer.

ABSTRACT
Ramipril is a prodrug belonging to the class of angiotensin-converting enzyme (ACE) inhibitor, which undergoes extensive hepatic first pass metabolism. The aim of the present study is to develop buccoadhesive bilayered tablet of ramipril  to achieve the greater therapeutic efficacy, to increase the bioavailability, to overcome the first pass hepatic metabolism of the drug. A UV spectrophotometric method has been employed for the estimation of Ramipril at 219 nm. Buccal tablets of Ramipril were prepared by direct compression method using ethyl cellulose as a polymer. The precompression parameters like bulk density, tapped density, carr’s index and angle of repose were determined. The post compression parameters like hardness, thickness, friability, weight variation, in vitro dissolution, FTIR studies were carried out to check if any interactions had occurred, results were promising. The optimized formulation was selected based on results and percentage drug release was found to be 92.95 and followed First order, peppas model with Fickian release mechanism.

ABSTRACT:
Microspheres are well accepted technique to control the drug release from the dosage form to improve bioavailability, reduce absorption difference in patients, reduce the dosing frequency and adverse effects during prolong treatment. The main objective of the present study is to prepare and evaluate ibuprofen  microspheres by solvent evaporation  method, with water insoluble polymers such as Ethyl cellulose and sodium carboxymethyl cellulose as suspending agent, using as carrier for oral administration in view to achieve oral sustained  release of the drug.  Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) used for relief of signs and symptoms of rheumatoid arthritis, osteoarthritis and is used in chronic and acute conditions of pain and inflammation. Its biological half-life is 2 ±0.5 hrs. Due to its low biological half-life (2 hrs), it requires frequent administration to maintain plasma concentration. This causes inconvenience to the patient and also leads fluctuations in plasma drug concentration that may cause inferior therapeutic effects or toxic effects. There-fore, development of controlled release dosage forms would clearly be beneficial in terms of decreased dosage requirements, thus increase patient compliance. The formulations were evaluated for particle size distribution analysis, flow properties like Angle of repose, bulk density, tapped density, Hausner’s Ratio, Carr’s index, Encapsulation efficiency, Scanning electron microscopy,optical electron microscopy and invitro release studies. The optimized formulation showed good invitro sustained  release activity of the drug ibuprofen.

ABSTRACT
Delivery of drug through Transdermal route represents a most convenient and novel approach. Transfersomes were found to be more effective as they render controlled release of drug due to depot formation in skin and were more effective in transdermal delivery. Transfersomes are applied to the skin and permeate through the stratum corneum lipid lamellar regions as a result of the hydration and osmotic force in the skin. Transfersomes have been widely used as a novel carrier for transdermal drug delivery. The Transfersomes can be evaluated by in vitro for vesicle shape and size, entrapment efficiency, degree of deformability, number of vesicles per cubic mm. Transfersomes enhances the penetration of most of the low as well as high molecular weight drugs. When tested in artificial systems transfersomes can pass through even tiny pores (100 nm) which are 1500 times smaller. The use of transfersomes carrier results in delivery of high concentration of active agents through the skin, regulated by system composition and their physical characteristics. Thus, this novel technique has got a great potential for overcoming current problems faced by the conventional techniques.
