Hydrogels are three–dimensional cross-linked hydrophilic polymers that swell in water and aqueous solutions without dissolving in them. Softness, smartness, and the capacity to store water make hydrogels unique materials.Several techniques have been reported for the synthesis of hydrogels like co-polymerization/crosslinking of co-monomers using multifunctional co-monomer, which acts as crosslinking agent. They can be classified in different ways on the basis of their preparation, biodegradable properties, polymer, sensitivity to surrounding environment and also their application. Hydrogels being biocompatible materials have been recognized to function as drug protectors, especially for peptides and proteins, from in-vivo environment. Hydrogels that are responsive to specific molecules, such as glucose or antigens, can be used as biosensors as well as drug delivery systems. This review mainly deals with the advantages, properties, method of preparation and characterization of hydrogels.

Abstract:
European Union is the big market for pharmaceuticals. Every pharmaceutical company wants to starts their business in European Union. In European Union come different countries like UK, Germany, France, Ireland, Sweden etc. In these countries various different process for new drug registration process like Nationalize process, Centralize process, Decentralize process, Mutual recognition process. Before that clinical trial approval also important for new drug registration. New drug registration process in European Union takes approximately 33 to 35 weeks. Each company must follow the rules and regulation for new drug registration. European medicine agency which gives the Clinical trial authorization and Marketing authorization to the new drug.

ABSTRACT
A  specific,  accurate,  precise  and  reproducible  RP-HPLC  method  has  been  developed  and subsequently validated for the simultaneous determination of Triamterene and Benzthiazide in tablets. The proposed HPLC method utilizes BDS hypersil (Thermo scientific) C18 column (250 mm × 4.6 mm id, 5 μm particle size), and mobile phase consisting of phosphate buffer: methanol (70:30) and pH adjusted to 3.5 with sodium hydroxide and flow rate of 1.0 ml/min. Quantitation was achieved with UV detection at 245 nm based on peak area with linear calibration curves at concentration ranges 10-30 μg/ml for Triamterene and 5-15 μg/ml for Benzthiazide. The retention time of Triamterene and Benzthiazide were found to be 5.960 min and 3.493 min respectively.  The  method  was  validated  in  terms  of  accuracy,  precision,  linearity,  limits  of detection,  limits  of  quantitation  and  robustness.  This  method  has  been  successively  applied  to tablet formulation  and  no interference  from the  formulation excipients  was found.

ABSTRACT
Purpose:
This study aimed to formulate Ambroxol hydrochloride SR matrix tablets using xanthan gum (natural polymer) and to elucidate the release kinetics of Ambroxol hydrochloride from xanthan gum-matrices. Methods: controlled release matrix tablets of ambroxol hydrochloride, a mucolytic expectorant  were prepared by wet granulation method using xanthan gum as natural hydrophilic polymer in three different ratios (Drug : Polymer 1:1(F-1), 1:1.5(F-2), 1:2(F-3)). The prepared granules of three different formulations were evaluated for angle of repose, bulk density (BD), tapped density (TD) and compressibility index (CI), hausners ratio. The prepared tablets were tested for physical parameters like weight variation, hardness, friability, content of active ingredient and In-vitro drug release studies. Results: The results obtained were within the prescribed limits. The release of ambroxol from the matrix tablets was sustained up to 12hrs. The cumulative percentage of drug release was decrease with increase in polymer concentration. Among the three formulations F-3 gave the release profile close to the commercially available marketed sample of ambroxol Hcl (A-MS).The results indicate that the drug release from the matrix tablets followed Zero order kinetics. The dissolution data was fitted to Korsmeyer equation which is used to describe the drug release behaviour from polymeric systems. All the formulations showed diffusion co-efficient value (n) greater than 0.43 but less than 0.85 after fitting to the Korsmeyer equation. So, it indicates Non-Fickian transport mechanism. Therefore the drug release is by diffusion and erosion mechanism. Conclusion: Matrix tablets of Ambroxol Hydrochloride using xanthan gum prepared by wet granulation method were found to be good in appearance. The drug-polymer ratio was found to influence the release of drug from the formulations. Formulation F-3 i.e. (1:2 drug: polymer) exhibited the similar In-vitro drug release rates as that of the marketed sample.

Abstract
Pulmonary function test are affected by the obesity. Various studies demonstrate important modifications in the pulmonary function tests of obese adults and adolescents, there is scarce information on obese children, and the findings remain inconclusive. Although there are some studies which demonstrate important modifications in the respiratory pattern of obese children, but there are some contradictory findings. So such type of study should be done which give us different and separate findings for overweight, mild obese, moderately obese, and morbidly obese criteria in obese school children in comparison with age, sex and ethnically matched control group.

Abstract
Antiulcer activity of aqueous extracts of  Annona squamosa seed extract was studied in Rats by pyloric ligation method. The  extract at dose of 100,200 mg/kg produced significant inhibition of gastric lesion induced by Pylorus ligation induced ulcer. The parameters taken to assess anti-ulcer activity were volume of gastric secretion, PH, free acidity, total acidity and ulcer index. The results indicate  that the alcoholic extract significantly (P  < 0.001) decreases the volume of gastric acid secretion, PH, free acidity, total acidity and ulcer index with respect to control.

ABSTRACT:
A new sensitive, simple, rapid and precise spectrophotometric method has been developed for simultaneous estimation of Torsemide and Amiloride HCl in pharmaceutical dosage form. This method was based on UV spectrophotometric determination of two drugs, using absorbance correction method. It involves measurement of absorbances at two wavelengths 288nm(λmax of Torsemide (TOR)) and 361nm (λmax of Amiloride HCl (AMI)) in methanol for the simultaneous quantitative determination of Torsemide and Amiloride HCl in the binary mixture without previous separation. The linearity was observed in the concentration range of 5 -25 μg/ml for Torsemide and 5-25 μg/ml for Amiloride HCl. The accuracy and precision of the method was determined and validated statically. The method showed good reproducibility and recovery with % RSD less than 2. Method was found to be rapid, specific, precise and accurate, can be successfully applied for the routine analysis of Torsemide and Amiloride HCl in combined dosage form without any interference by the excipients. The method was validated according to ICH guidelines.

ABSTRACT:
The incidence of type 2 diabetes mellitus is increasing worldwide. The pharmacotherapy for type 2 diabetes until the last decade only consisted of biguanides, sulphonylureas, and insulin. The existing therapeutic classes of antidiabetic drugs are not adequately effective in maintaining long-term glycemic control in most patients, even when used in combination. One emerging novel therapeutic class of antidiabetic drugs is sodium glucose cotransporter 2 (SGLT2) inhibitors. SGLT2 accounts for 90% of the glucose reabsorption in the kidney. The SGLT2 inhibitors increase urinary excretion of glucose and lower plasma glucose levels in an insulin-independent manner. Forxiga (Dapagliflozin) the most prominent molecule in this class is currently approved by USFDA. Other members of this class (eg, sergliflozin, remogliflozin) are also effective. This class of novel agents can effectively control blood sugar level without producing weight gain or hypoglycemia.
