ABSTRACT
In 16^th century physician were of the opinion that magnet can be used for the treatment or eliminate the diseases from the body. Here the reports about the chemical synthesis, protection, functionalization and application of magnetic nanoparticles of nano structured system. Research of magnetic nanoparticles for targeted drug delivery system and function of magnetic nanoparticles on particular area are reviewed. Use of magnetic nanoparticles for cancer diagnosis has been advancing day by day. This review is related to the multifunctional use of magnetic nanoparticles probes and their use in bio imaging and nano medicine.

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
The science of physics is understood to be very away from the Pharmaceutical Science. But in the real context, Physics is found to be most densely involved in the Pharmaceutical Science than any other field of science. Physics can be considered as a backbone that supports Pharmaceutical Science. The advance technology that describes that formation and its mode of action to the biological organ is Physics. The structure, action and result of Pharmaceutical material are explained by the theories of Physics.

ABSTRACT:
The aim of present investigation is to formulate evaluate and optimization of colon targeted pellets bearing mebendazole, benzimidazole derivative with broad spectrum of anthelminthic activity. It is highly effective against adult and larval stages of ascaris lumbricoids, hook worms and  indicated for the treatment of nematode infestation. Pellets were prepared by extrusion spheronization process using microcrystalline cellulose as spheronizing aid, natural polysaccharide pectin as binders in three different percentages i.e 5%, 10% and 15% and glycerine as plasticizer.  Further study was carried out to select the natural polysaccharide for formulation of colon targeted pellets i.e. Pectine, Xanthan gum and Guar gum. The formulation were prepared with optimized constant process parameters i.e. Percentage LOD 10%, Spheronization time 3 minutes and Speed of spheronization 700-1200 rpm. Prepared A1 – A9 batches were then evaluated by their micromeritic properties like tapped density, carr’s index, hausner, S ratio, angle of repose  and characterized by microscopic study, % yield, hardness, friability, % assay and dissolution study was carried out and compared with marketed formulation by statistical analysis similarity factor (f₂). The batch A5 is having 10% pectin, 18% MCC and 20% mebendazole shows (22.20±2.05) % carr’s index, (1.22±0.04) hausner’s ratio, (26.65±1.15) angle of repose, (88.2±2.36) % yield, (3.96±0.46) hardness, (0.23±0.03) % friability  (88.47±3.26) % assay and (99.81±3.80) % drug release after 10 hours. Pellets equivalent to 300mg of mebendazole  were then filled in capsules and capsules coated with 12.5% w/v Eudragit S 100 using optimized 4- 5 ml/min spray rate, 15 rpm pan speed and 40±5°C coating inlet temperature and then optimized for % weight gain in four different trials. W2 batch having 10% weight gain were then evaluated by % cumulative drug release, disintegration test in 0.1 N HCl shows (99.73±3.34) % CDR, intact after 12 hours. The pellets of batch A5 and the enteric coated capsule with 10 % weight gain were packed in aluminum pouch and charged for accelerated stability studies at (40°C±2°C) and (75%±5%) RH for 1 month in a stability chamber shows no change in the dissolution profile at (40°C±2°C) and (75%±5%) RH storage condition.

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.
