Abstract
Aromatase and 17-ßHSD inhibitors are main target of pharmacological interest for the treatment of estrogen dependent cancers. Chalcones, Coumarins, Flavones, Isoflavones have been reported for such inhibition and are used for treatment of breast tumors. So in this topic, Flavone derivatives containing Imidathiadiazole, Thiadiazole, Triazole and benzimidazole hetrocycles synthesised by using simple laboratory reagents like 2-Hydroxy Acetophenone and 4-Hydroxy Benzaldehyde to convert chalcone leads to formation of Flavones by cyclazation using Microwave and followed by attachment of different hetrocycles to form Flavone derivatives and charactrarized by IR, ¹H NMR, ¹³C NMR spectroscopy and elemental analysis. These Flavone derivatives found to exhibit moderate to high inhibitory activity against Estrogen dependent cancers.

ABSTRACT:
The aim of the present study was to prepare and evaluate buccal tablet comprising a drug-containing buccoadhesive layer and a drug-free backing layer, by the direct compression method. The mucoadhesive layer was composed of a mixture of drug, hydroxypropylmethylcellulose (HPMC K4M), Carbopol 934P (CP), Sodium carboxy methyl cellulose (NaCMC), and the backing layer was made of ethyl cellulose. Enalapril maleate is an ace -inhibitor was formulated onto buccoadhesive tablets to overcome the limitations in the currently available dosage forms and routes of administration which in sequence will increase patient’s compliance. Formulations (F1-F9) were developed and subjected to various evaluation parameters. All tablets were acceptable with regard to thickness, weight variation, hardness, and drug content. Maximum bioadhesive force was observed in tablets formulated using CP-NaCMC as a bioadhesive polymer (F4-F6). Formulation F6 showed maximum permeation of 91.98 % ± 0.58 in 8hr. Formulation F3 showed maximum swelling index of 2.99 ± 0.01 after 8hr. The mucoadhesive force and residence time of the optimized batch F6 are 0.14 N ± 0.01 and 9.10 hrs ± 1.15 respectively. The results indicate that suitable buccoadhesive tablets with desired properties could be prepared.

Abstract:
Venlafaxine HCl is an anti depressent drug which is used in depreesion. It is available both as immediate release tablet as well as modified release product. The innovator modified release product available in international market is Effexor ER tablets. Effexor ER is based on erosion matrix system. The core tablet is coated with Ethyl Cellulose using PVP as a core former. This coating is solvent based coating. The aim of present investigation was to prepare a ER tablet of Venlafaxine HCl with similar dissolution profile matching to Effexor ER using swelling matrix system. The platform developed for this product was compression coating. An immediate release core tablet of 100mg was prepared and it was compression coated using HPMC matrix system. HPMC of three viscosity grades was selected and the concentration and the viscosity grade were optimised. Similarity factor ( F2 values) with innovator product were calculated for in vitro dissolution profile. The rank order correlation for similarity factor was as under HPMC K15M 15% > HPMC K100M 15% > HPMC k15M 35% > HPMC k100M 35% > HPMCK 4M 15% > HPMC k45 45%. In this review, current and recent developments of venlafaxine hydrochloride extended release products are discussed.

ABSTRACT
The importance for medicinal herbs is increasing day by day due to its high availability and lower side effects. The present study investigated the total phenolic and flavonoid content of various extractions of Indigofera tinctoria linn. The total phenolic content was determined by folin-ciocatechu reagent using Gallic acid as standard and total flavnoid content by aluminium chloride assay using Quercetin as a standard. The present study showed the ratio of phenolic and flavonoid content in different extracts of Indigofera tinctoria linn. Aqueous extract showed the more flavonoid and phenolic content in comparision with other extracts.

ABSTRACT
The present study behind this work is to find to prepare sustained release tablets of Viloxazine by compression method. First of all to formulate Viloxazine sustained release tablets using the Ethylcellulose, Carbopol, Sodium Alginate, Hydroxy propyl methyl cellulose & Guar gum under ratio’s like 1:1, 1:1, 1:1,1:1,1:1 . Five batches were made in various polymers of ethylcellulose, carbopol, sodium alginate,hydroxy propyl methyl cellulose & guar gum is used by keeping the drug as constant. Then evaluation of Viloxazine sustained release tablets was carried out for characteristics like drug content in tablet, UV analysis. In vitro release starts from 1hr and up to 24hrs. It shows the percentage of gradual drug release as 17.80%, 27.65%, 35.12%, 45.16%, 51.20%, 57.42%, 61.30%, 66.32%, 72.08%, 77.15%, 81.32%, 84.48% & 98.20% against the label claim as 40mg.

Abstract
The first and the second generation type of dosage forms had been found to have lower efficacy of drug reaching to the targeted tissue this lead to need for third generation drug delivery system which contains the liposomes, microspheres, microcapsules, nanodiamonds etc. with these type of drug delivery system it had been found to have better patient compliance and reduced side effects. The present paper deals with the same as there is first formation of Metformin double emulsion and then precipitation of the drug from the polymeric solution. In this study challenge was to encapsulate Metformin with high entrapment efficiency by w/o/o double emulsion solvent diffusion technique using non-aqueous processing media. The primary requirement of this method to obtain microsphere is that selected solvent for polymer must be immiscible with non aqueous processing media, so to fulfill the requirement.
