ABSTRACT
Pressurized metered dose inhalers (MDIs) are widely used dosage form for treatment of respiratory diseases, such as asthma and chronic obstructive pulmonary disease. The metered dose inhaler (MDI) contains the active pharmaceutical ingredient dispersed or solubilised in a high vapour pressure propellant and metered accurately in tens to hundreds of micrograms and administered directly to the lungs. The most dominant characteristics of MDI include their portability, convenience of use and quick effect. MDI comprises of drug formulation, propellant, metering valve, actuator, and container. This review contains overview of excipient selection, primary packaging material, propellant selection and formulation development of pMDI. Two of the most commonly used methods for the manufacturings of MDIs are cold filling method and pressure filling method.This review demonstrates different analytical techniques for characterization of pMDI’s like uniformity of delivered dose, water content, spray pattern and plume geometry were discussed. This review also presents in-vitro characterization, pharmacokinetic and pharamcodynamic study of MDI.

ABSTRACT
Nanoparticle, a core of bio-nanoparticle, which is used for polymers including natural and synthetic polymer and form different types of, liposomal and polymer nanoparticle. The designing, synthesis and manipulation of structures which is smaller than 100 nm, is termed as Nanotechnology. Nanoparticles are developed as a colloidal structure, synthesized by semi-synthetic and synthetic polymers. The emerging area of nanotechnology and Nano-sciencesare the application of nanoparticles, ranges in 1 to 100 nanometre (nm). The synthesis of silver nanoparticles for their potential application, it was originate to be eco-friendly and reliable, because of their exclusive properties. Mostly synthesis of AgNPs, by physical and chemical methods are too expensive, toxic, hazardous chemicals for various biological risks.The main objective of this study preferably lies thatgreen synthesis of AgNPs by several plants and its metabolites, extracts can be much safer to handle and easily available. The synthesis of AgNPs  are using several plants extract such as Oryza sativa, Zea mays, Basella alba, Helianthusannuls, Camellia sinensis ( green tea), Azadirachta indica (neem) ,Ssebania drummondii (leguminous shrub)sp. The AgNPs get attached in the cell wall of microorganism and can disturb the cellular respiration, permeability of the cell wall. Sometimes it can penetrate inside the cell wall which can interact protein, DNA, sulphur and phosphorus and causing cellular injury inside cell. It confers the antimicrobial activity. The AgNPs shows less antimicrobial activity against gram positive bacteria in comparison to gram negative bacteria because gram negative contain β-barrel proteins (i.e. Porins) and thinner peptidoglycan. The distinguishing property of silver nanoparticles it can be have higher surface area to volume ratio. When surface area increases the catalytic activity and surface energy of AgNPs corresponding to increase and biological effectiveness also increases. 

It identified that amalgamation of silver nanoparticle biochemical process is very fast process as compare to using microorganism (even several hours to few days). The NPs monodispersity, size are significant part in the valuation of NPs amalgamation. Therefore, operative regulator of monodispersity and NPs size are essentially examined. On numerous readings silver nanoparticle synthesis by microbes can be decompose later withassured dated of time. Thus the constancyof nanoparticle producebiological approachesmerits supplementary learning.

ABSTRACT
A radiopharmaceutical is a preparation intended for in-vivo use that contains a radionuclide in the form of a simple salt or a complex.  It may exist as a solid, liquid, gas or a pseudo gas. The chemical and physical identity and a form of a radiopharmaceutical are very important because in each case, once administered the radiopharmaceutical is intended to target certain tissues, binding sites, biochemical pathways. A radiopharmaceutical can be used for either diagnostic or therapeutic purposes depending on its specific physicochemical and radiation properties. The characteristic of radioactive decay is what makes radioisotopes useful in their medical applications; however, different applications will take advantage of radioactive emissions in different ways. Radioactive materials are regularly used to treat medical conditions, diagnosis pathology, visualize and measure physiological functions, and localize structures and pathways. This review describes both the therapeutic as well as diagnostic uses of radiopharmaceuticals.

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.
