A mixture of oil and surfactant (especially non-ionic) forms clear and transparent isotropic solution known as self-emulsifying system (SES). Lovastatin is HMG-CoA enzyme inhibitor. This enzyme is needed by the body to make cholesterol. Lovastatin causes cholesterol to be lost from LDL, but also reduces the concentration of circulating LDL (low density lipoprotein) particles. Animals studies demonstrated that lovastatin crosses the blood-brain and placental barriers. Elderly patients or those with renal insufficiency may have higher plasma concentrations of lovastatin after administration and may require a lower dose. SEDDS is prepared and filled in hard gelatin capsules. In vitro dissolution indicates that the release of lovastatin from SEDDS varied according to the type and ratio of the oil and surfactants. It was concluded that there was an increase in both the solubility and dissolution rate of drug in SEDDS form as compared to marketed tablet.Keywords

The phenomenon of absorption via a limited part of the GI tract has been termed the "narrow absorption window", once the dosage form passes the absorption window, the drug will be neither bioavailable nor effective. In extreme cases, drugs, e.g. methyldopa, Captopril, that are insufficiently absorbed due to narrow absorption cannot be delivered entirely, and are either given by a parentral route, or the development of such medication, which is otherwise safe and effective, is stopped altogether. Diltiazem HCL is a calcium channel blocker widely used for the treatment of angina pectoris, arrhythmias and hypertension. Its short biological half life and thus frequent administration (usually three to four times a day) makes it a potential candidate for CR: SR preparations. It has a short plasma half life of about 3 hours. Diltiazem HCL microspheres were prepared by chemical cross linking method. The microspheres were spherical, discrete and free-flowing. Encapsulation efficiency was found to be 95.62 %. Diltiazem HCL release from microspheres was slow and diffusion controlled. Good liner relationships were observed between percent coat and release rate of the microspheres.Keywords

The objective of this investigation was to develop an intra gastric floating drug delivery system of clarithromycin and also attempts were made to sustain the release of clarithromycin. Multiple-unit floating beads of clarithromycin were prepared from sodium alginate solution containing Hydroxypropylmethylcellulose (K100M) and sunflower oil by using emulsion-gelation method. These beads were evaluated for entrapment efficiency, drug loading, buoyancy and in vitro drug release. All formulations were the floating lag time below two minutes and shows total floating duration more than ten hours. It was observed that entrapment efficiency, drug loading and buoyancy was greater with formulation containing two percent sodium alginate solution and five percent calcium chloride solution along with 500mg HPMC and five ml sunflower oil (i.e.F14) and also the result of in-vitro dissolution studies reveals that the formulation F14 gave sustained release pattern of clarithromycin upto 12 hrs.Keywords

The pain is symptomatic of some form of dysfunction and resultant inflammatory processes in the body. More than 15% of the worldwide population suffers for instance from some form of osteoarthritis and this incidence is even higher in elderly. As the world population is grows older, this incidence will continue to rise. Aceclofenac has been shown to have potent analgesic and anti-inflammatory activities and due to its preferential cox-2 blockade it has better safety than conventional NSAIDs with respect to adverse effects on gastrointestinal and cardiovascular system. Ethyl cellulose microspheres of Aceclofenac were prepared by emulsion- solvent evaporation technique that is an industrially feasible technique. The microspheres are spherical, discrete and free-flowing. Encapsulation efficiency was found to be 81%. Aceclofenac release from microspheres was slow and diffusion controlled. Good liner relationships were observed between percent coat and release rate of the microspheres. These microspheres were found suitable for oral controlled release.

Medicinal plants contribute in human health care system. Most of the plants utilized by village peoples as a folk medicine. Now we are turned in to medicinal plant analysis of active compounds and conservation aspect. In the present study we had select the four important medicinal plants in the Khandesh region. Such plants are widely used in this region for ayurvedic purpose by villagers and local herbal health masters. We have colleted four medicinally important medicinal plants such as Acalypha indica, Cassia auriculata, Eclipta alba and Phyllanthus niruri for antimicrobial studies. The experiment carried out in the selected medicinal plants leaves and ischolar_mains. The results are discussed with the available literature.- Preparation and Evaluation of Inclusion Complexes Using Cyclodextrins and Its Derivatives

Domperidone is a widely used antiemetic, poorly water soluble drug, erratically absorbed in stomach and possess several dissolution related problems thus it has poor bioavailability. Solubility of a drug plays a very important role in dissolution and hence absorption of drug which ultimately affects its bioavailability. Hence, by considering the facts related to drug, attempts have been made to formulate inclusion complexes using various derivative of cyclodextrins.
Inclusion complexes were prepared using methylated betacyclodextrin and hydroxy propyl betacyclodextrin in 1:1 and 1:2 molar ratios. Kneading, ultrasonification and physical mixture method were used for preparation of inclusion complexes. The solubility and dissolution results revealed that there was an increase in solubility and dissolution of all inclusion complexes as compared to pure drug but was highest in case of methylated betacyclodextrin in 1:1molar ratio using ultrasonification method(USM1) and with hydroxypropyl betacyclodextrin in 1:2 molar ratio using ultrasonification method(USHP2).

An abundance of the anti-inflammatory drugs are available for use in current medicine which have an established use in the treatment of arthritis and other painful conditions, amongst them one of the novel drug is Aceclofenac. Gels are an excellent formulation for several routes of administration such as oral, topical, nasal, vaginal, and rectal. Gel can be clear formulations when all of the particles completely dissolve in the dispersing medium. But this doesn't occur in all gels, and some are therefore turbid. This need has emphasized the importance of developing a topical dosage form of such drugs.
Aceclofenac is novel non steroidal anti-inflammatory drug which have proven its effectiveness in many of painful diseased conditions like osteoarthritis, rheumatoid arthritis, spondylitis etc. Like other NSAIDs it is also associated with adverse effects, majority of them are of gastrointestinal system (dyspepsia, abdominal pain, nausea and diarrhea). Present study was undertaken to develop an effective and stable topical formulations of Aceclofenac gel.
