Valsartan is an orally administered ACE inhibitor for the treatment of hypertension and cardiac failure, but its solubility and oral bioavailability are poor. The objective of investigation is to formulate a microemulsion drug delivery system of valsartan using minimum surfactant concentration that could improve its solubility and oral bioavailability. Valsartan microemulsion were prepared by Phase-titration method. The composition of optimized formulation consist of Capmul MCM(Oil), Tween 20 (Surfactant),PEG 400(Co-Surfactant) and it contains 40 mg of Valsartan.Pseudo-ternary phase diagrams were plotted to check for the micro-emulsification range. Prepared microemulsion formulations were tested for micro emulsifying properties and the resultant microemulsion were evaluated for robustness to dilution, viscosity, drug content, thermodynamic stability studies and in-vitrodissolution. The optimized microemulsion formulation further evaluated for thermodynamic stability studies, particle size distribution, and zeta potential to confirm the stability of the formed Microemulsion. Resultant microemulsion optimized formulation (F2) shows drug release (99.71%), droplet size (36 nm), viscosity (0. 8872 cP), Zetapotenial (-38.8 mV) and infinite dilution capability. The formulation was found to show a significant...

Aim: To check the effectiveness of 0.15% Benzydamine hydrochloride on oral mucositis secondary to cancer chemotherapy Methods: In the past few years, multiple cases were referred to our department for the management of oral manifestations of cancer chemotherapy for various malignancies. Out of these patients, we selected 5 patients and used a simple, inexpensive treatment modality in consideration with patient’s affordability and convenience. They were prescribed 0.15% Benzydamine hydrochloride oral rinse (Tantum) for the relief of oral discomfort. Results: Significant reduction in oral mucositis and discomfort was observed after a week. The treatment was continued for 3 weeks till complete disappearance of oral ulcers. Conclusion: Benzydamine oral rinse is simple, effective, safe, inexpensive and well tolerated therapeutic modality for prophylactic and palliative treatment of chemotherapy-induced oral mucositis. It holds a special significance in the developing countries such as India for the lower socioeconomic...

Tinospora cordifolia is known for a wide range of medicinal properties. In this study, cardiovascular and antimicrobial properties of aqueous and ethanolic extracts of Tinospora cordifolia were evaluated. Dose dependent negative ionotropic and chronotropic effects were observed with both aqueous and ethanolic extracts. The effects were antagonized by atropine indicating involvement of muscarinic receptors. Maximum antimicrobial activity was found with ethanolic extract of Tinospora cordifolia (15mm) against Pseudomonas aeruginosa. The organism showed resistance to aqueous extract giving an inhibition zone of 0.3mm. The data suggest that Tinospora cordifolia could be of benefit in arrhythmias and microbial infections....

Tridax procumbens L. is a well known medicinal plant. In the present study alkaloids from pedicle and buds of the plant were extracted and evaluated for antimicrobial activity by ‘Disc Diffusion Assay’ against selected bacteria (Escherichia coli, Staphylococcus aureus and Proteus mirabilis) and fungi (Aspergillus flavus, Aspergillus niger, Candida albicans and Trichophyton mentagrophytes). Minimum inhibitory concentration, minimum bactericidal/fungicidal concentration and total activity of each active extract were also evaluated. Significant antibacterial activity was recorded by alkaloids of pedicle against P. mirabilis (IZ 20mm, AI 0.83 and same MIC, MBC 0.039 mg/ml) and antifungal activity was recorded by buds against C. albicans (IZ 9.2mm, AI 0.92, MIC 0.625 mg/ml and MFC 1.25 mg/ml). MIC ranged from 0.039 mg/ml-0.625 mg/ml and MBC/MFC ranged from 0.039 mg/ml-1.25 mg/ml against susceptible pathogens. It is noteworthy that MIC values of active extracts was found very low (0.039 mg/ml-0.625 mg/ml) and was recorded below 1 mg/ml against inhibited pathogens, thus ascertain their strong antimicrobial potential against selected microbes. Thus, the result of the present study...

Cassia nodosa Bunch.is an ornamental tree belonging to family Leguminosae, popularly known as Pink Shower is a perennial tree. Laboratory evaluations were made to asses the study of primary metabolites in different plant parts of Cassia nodosa Bunch. The highest amount of soluble sugars (10.27mg/ gdw), lipids (32.36mg/gdw), phenols (20.0mg/gdw), DNA (11.78mg/gdw) and Chlorophyll- a+b (0.94mg/gdw) was observed in pods, ascorbic acid (0.867 mg/gdw), proteins (115.0mg/gdw), RNA (4.60mg/gdw) and carotenoids (0.554mg/gdw) in leaves and starch (10.02mg/gdw) in stems. Similarly lowest amount of proteins (39.48mg/gdw), phenols (4.67mg /gdw), RNA (0.49mg/ gdw) and DNA (1.76mg/gdw) was observed in leaves, starch (3.76mg/gdw) in flowers, soluble sugars (2.45mg/gdw), lipids (3.48mg /gdw), ascorbic acid (0.089mg/gdw) in...
