Abstract
To evaluate the anti-inflammatory and analgesic activity of methanolic extract of whole plant of Sida acuta in experimental animal models. Methanolic extract of whole plant of Sida acuta (MESA) (100, 200 and 400 mg/kg p.o.) was studied for its anti-inflammatory activity using Carrageenan induced rat paw edema animal model and analgesic activity at the same dose level using acetic acid induced writhing test and Hot plate analgesia in mice. The methanolic extract of whole plant of Sida acuta (MESA) (100, 200 and 400 mg/kg p.o.). The PI with indomethacin and Sida acuta in carrageenan induced paw edema  at the dose level 400 mg/kg were 60% and 52.5% at the end of 5 hr. In the acetic acid induced writhing test, the extract at the dose level 400 mg/kg showed 83.78% inhibition of writhing. In radiant heat tail- flick method the extract  at the dose 400 mg/kg showed reaction time 4.902 ± 0.545 (p<0.001). The methanolic extract possesses anti-inflammatory and analgesic activity.

ABSTRACT:
The main goal of this study was to develop a stable formulation of antibiotic drug clarithromycin as an immediate-release tablet. The task of developing immediate release tablet is accomplished by using a suitable diluents and super-disintegrants. Faster disintegration of the tablet administrated orally minimizes absorption time and improves its bioavailability in less time.   The formulation development work was initiated with wet granulation. Microcrystalline cellulose PH 102 were used as diluent. Povidone was used as the binder. Croscarmellose sodium and pre gelatinized starchwas added as a disintegrating agent. Talc and magnesium stearate was used as the lubricant. The prepared granules were compressed into a compression machine.  To evaluate the formulated tablets as per requirements of standards. The tablets thus formulated showed  a satisfactory physical parameters, and it was found to be stable.Evalution Parameters Like weight variation, hardness of the tablet, friability, thickness, disintegration test, drug content uniformity and in vitro release studies were performed.To optimize the trial batch by    3² full factorial design study and determined  the best batch by in vitro release studies are showed that  optimization formulation (OF7) was 101.62% respectively. The  optimized formulation is further selected and compared with the release profile of the innovator product. The results suggest the feasibility of developing immediate  tablets consisting of clarithromycin for the convenience of patients with respiratory infections, gonorrhea, community-acquired pneumonia, pelvic inflammatory disease, pediatric otitis media and pharyngitis and Mycobacterium avium complex (MAC) in patients with advanced HIV disease.

The history of the IIT system dates back to 1946 when a committee was set up by Hon'ble Sir Jogendra Singh, Member of the Viceroy's Executive Council, Department of Education, Health and Agriculture to consider the setting up of Higher Technical Institutions for post war industrial development in India.

The Medisynth Group is a self contained group, something that is unique in the homoeopathic industry. It is also among the few to maintain global standards of manufacturing in the industry.
Medisynth’s collaboration with Beck & Koll Laboratories provided the Medisynth Group with the foothold that has been maintained admirably even today. By constantly innovating and introducing newer variations, Medisynth always stays one step ahead of the rest.

ABSTRACT
The Goal of the present investigation was to design and evaluate gels for topical delivery of water insoluble antifungal agent, Clotrimazole with an aim to increase its penetration through skin. Clotrimazole is a broad spectrum imidazole derivative useful in the treatment of superficial fungal infections. Purpose was to improve the solubility, invitro characteristics and dissolution properties of Clotrimazole by the preparation of its solid dispersion with beta cyclodextrin using kneading method by using different drug carrier ratios. Prepared solid dispersion was evaluated for percent practical yield, drug content uniformity, in vitro dissolution rate, DSC and IR studies. Solid dispersions was optimized based on the release characteristics, and were incorporated into gels. Faster dissolution was exhibited by solid dispersion containing l: l ratio of drug: β-cyclodextrin by kneading method. Gels have gained more importance because the gel-bases formulations are better percutaneously absorbed than creams and ointment bases. The gels were formulated by using Carbopol 940, HPMC, and Methyl cellulose and evaluated for pH, drug content, spreadability, extrudability, viscosity determination and diffusion study. Invitro drug release of clotrimazole solid dispersion incorporated gels was showed that Carbopol gels was showed higher drug release as compared to HPMC, methyl cellulose gels.  Optimized gel was then undergone skin irritation test, stability studies, and invitro antifungal test. In conclusion, the optimized gel showed good physicochemical properties, better drug release, and reasonable stability
