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.

ABSTRACT:
Itopride Hydrochloride is a novel, synthesized, gastro prokinetic drug, which stimulates gastrointestinal motor activity through the synergistic effects of dopamine D2-receptor blockade and acetylcholine esterase inhibitors. Chemically, it is N-[[4-[2-(Dimethyl amino) ethoxy] phenyl] methyl]-3, 4-dimethoxy benzamide hydrochloride. Benzamide structure, amide and ether linkages in the drug molecule make it susceptible to degradation. Thus a prokinetic drug like Itopride Hydrochloride by virtue of its efficacy and tolerability could be considered as a drug of first choice and a welcome addition to the drug armamentarium for the symptomatic treatment of NUD (non-ulcer Dyspepsia) and other gastric motility disorders including functional bowel disorders. This review consists of various analytical methods for determination of Itopride Hydrochloride in various marketed pharmaceutical preparation and in biological fluids. Analytical method consists of various spectroscopic methods, chromatographic methods and other methods.

ABSTRACT
Industry and regulatory bodies responsible for public health are actively assessing animal free tests to reduce the requirement for Draize testing. Draize rabbit eye irritation test developed in the 1940’s is even today the only eye toxicity test officially accepted in the OECD countries for regulatory purposes in the classification of slightly and moderately irritating chemicals. The Draize test has been widely criticized for both scientific and ethical reasons, and alternatives have been investigated for several decades. Therefore in an attempt to minimize this conflict alternative methods have been investigated. This article presents those alternative methods that are currently the most developed and the most widely used.
