The purpose of this research was to develop fast disintegrating tablets of Salbutamol Sulphate using superdisintegrating agents. Recently fast disintegrating drug delivery system have started gaining popularity and acceptance as new drug delivery system, because they are easy to administer and lead to better patient compliance. Salbutamol Sulphate is a selective β2 receptor agonist widely used as a bronchodilator. It forms part of initial therapy of acute as well as chronic asthma. In present work an attempt has been made to formulate and evaluate fast disintegrating tablets of Salbutamol Sulphate. Ac-di-sol, Polyplasdone and Primojel were used as super disintegrating agents, while microcrystalline cellulose and mannitol were used as diluents. Direct compression technique was used as it requires conventional tablet machinery and thus economical process. Formulations containing Ac-di-sol as super disintegrating agent show rapid in-vitro and in-vivo dispersion time as compared to other...

The antioxidants such as quercetin and alpha- tocopherol were subjected for in vitro prophylactic cataract prevention study on glucose induced cataract model. Goat lenses were incubated in artificial aqueous humor containing 55 mM glucose with test drugs in different concentrations at room temperature for 72 h. Biochemical parameters studied in the lens were electrolytes (Na+, K+), Na+– K+– ATPase activity, malondialdehyde (MDA) and proteins. Glucose induced opacification of goat lens began 8-10 hrs after incubation and was complete in 72-80 hrs. Cataractous lenses showed higher Na+, MDA (P<0.001), lower Na+-K+– ATPase activity, and water-soluble protein content. Lenses treated with test drugs has shown higher protein content and prevented formation and progress of cataract by glucose, as evidenced by biochemical parameters....

Paracetamol is an important anti-inflammatory and analgesic drug widely used in biological disorders. One of major problems with this drugs is its low solubility thus dissolution rate in biological fluid, which results into poor bioavailability after oral administration. In this study polyvinyl pyrrolidone (PVP) is used to enhance bioavailability of paracetamol. Paracetamol and PVP are used in 1:1 and 1:2 ratios to study the effect of PVP in dissolution profile of drug. Dissolution study showed a linear increase in paracetamol release with increase in polymer concentration. Two different batches of granules are also evaluated for their micromeritics properties and flow behavior. The micromeritics properties and dissolution profile showed a evident that PVP can be used to improve dissolution behavior of...

Barberries are a large group of evergreen shrubs, found in Lalitpur, Allahabad, Bhopal and Haldwani etc. It is an evergreen shrub. Commonly, its fruits are called as berries. This plant is generally use in case of diabetes and mouth ulcer, as a traditional use. Type 2 diabetes mellitus (formerly called NIDDM, type II or adult-onset) is characterized by insulin resistance in peripheral tissue and an insulin secretory defect of the β- cell. This is the most common form of diabetes mellitus and is highly associated with a family history of...

Psoralia corylifolia commonly known as Babchi, Bavachi in Hindi, is a well known herb in Indian system of medicine to treat various disorders including diabetes mellitus without any scientific evidences. Therefore this study was designed to investigate in vivo hypoglycemic and antidiabetic potential of methanolic extract of seeds of Psoralia corylifolia in glucose loaded animals and alloxan induced diabetic animals. In both the models Psoralia corylifolia reduced the blood glucose level when compared to diabetic control group and exert a significant hypoglycemic and antidiabetic activity. However the potency of the herb was less than that of standard drug metformin. Psoralia corylifolia methanolic extract also reversed the body weight in normal and alloxan induced diabetic animals. The results of this study revealed the presence of a significant antidiabetic potential of methanolic extract of Psoralia corylifolia in alloxan induced diabetic rats. On the basis of this further research work is needed to investigate exact mechanism of action and also to isolate the active constituent/s responsible for the...
