The aim of the study was to prepare Temozolomide loaded solid lipid nanoparticles and evaluating loaded solid lipid nanoparticles. Temozolomide loaded solid lipid nanoparticles were prepared by micro emulsification method using different lipid (stearic acid) concentration keeping drug concentration unchanged, poloxamer 188 and cetyl alcohol as surfactant and co-surfactant. The prepared SLN were characterized for surface morphology by SEM analysis, drug loading and % entrapment efficiency, FTIR, zeta potential and in vitro diffusion studies. The lowest and highest % Entrapment Efficiency was found to be 85.85% and 97.45% for F1 to F5 batches respectively. Release studies were done by using saline phosphate buffer pH 7.4 using dialysis bag diffusion method. Zeta potential was found to be – 20.3 mV and particle size was found to be 119.34. For 8 hrs in vitro drug release found to be 79.16%, 74.45%, 71.42%, 61.36%, and 55.13% respectively. The release data was analysed by different kinetic models and found that the formulations best fit model is peppas and the drug release mechanism was...

Objective: To study prescribing pattern for acute respiratory infections in children attending outpatient department of Paediatrics, J.L.N. Hospital, Ajmer, Rajasthan. Material and Method: The study was carried out retrospectively by analyzing the copies of prescriptions of patients who had visited the O.P.D. of the paediatrics department of J.L.N. Hospital Ajmer. A total of 350 prescriptions having written diagnosis ARI/URTI/common cold were selected for study. Information on demographic profile and treatment were spread over three different age groups (i.e. Neonates: up to one month of age, Infants: 1 month to 1year and Children: 1-14 years). Each prescription then was analyzed as per objectives of study. Results: Male patients were more as compared to females and most of the patients were in the age group of 1-14 years. Antihistaminics were the most frequently prescribed class of drugs (28.52%) followed by antimicrobials (26.35%). Antihistaminics constituted 63.08% of respiratory drugs prescribed. Antimicrobials were prescribed in 86.57% of the prescriptions and Cefpodoxime was the most frequently prescribed antimicrobial agent followed by Amoxicillin-clavulinic acid combination....

Microspheres containing Repaglinide was prepared by emulsion solvent evaporation technique using two types of surfactants Tween 80 (polysorbate 80) and Span 80 (Sorbitanmonooleate 80). The effect of change in the type and surfactant amount on the size and drug release from the microspheres was investigated. The release of Repaglinide from the microspheres exhibit diffusional characteristics and closely follows Higuchi Model and also highly correlated with first-order release model. The in-vitro release study was performed in pH 6.8, phosphate buffer Solution and 0.1N HCl. Scanning electron microscopy study revealed that the microspheres were spherical and porous in nature. In vivo testing of the microspheres in diabetic albino rats demonstrated significant antidiabetic effect of Repaglinide. Repaglinide loaded microspheres expected to give new choice for safe, economical formulation for effective management of NIDDM. A clear correlation between the types of surfactant on mean diameter of the microspheres was found. When Span 80 was used, the microspheres were smaller in size as compared to those obtained using Tween 80, while there was a...

Self nano-emulsifying system drug delivery system (SNEDDS) is promising for drugs of BCS class II. The objective of present study to develop self nano-emulsifying drug delivery system for Lipophillic drug Telmisartan (antihypertensive drug), labrafil 1944, Kolliphor ELP: Span 80 (1:1) and PEG 400: Ethanol (1:1) was chosen as oil, Surfactant and Co-surfactant as they show higher solubility for Telmisartan. Screening of Surfactant, Co-surfactant done by percent transmittance and were also observed for turbidity or phase separation visually. Pseudo ternary phase diagram were constructed to identify the self emulsifying regions and also to establish the optimum concentration of oil, surfactant and co-surfactant. Box bhenken desine applied for optimization of formulation. Prepared formulation further Characterization done. Percent Drug Content found 99.71, thermodynamic stability studies show homogenous and no phase separation, Emulsifying Study performed transparent appearance after 24 hr, for robustness Dilutability in water and 0.1N HCl give Percentage Transmittance 99.5 and 100, conducting in vitro dissolution test compared with marketed preparation in stimulated gastric (S.G.F) pH 1.2 showed Percent Drug Release...

Coleus forskohlii is an herb historically used in Ayurvedic medicine. Nowadays Coleus forskohlii is used as a fat burning supplement in various formulations and available in the Indian market. Forskolin the main constituent of this plant is used to treat allergies, skin conditions such as eczema and psoriasis, painful menstrual periods, irritable bowel syndrome (IBS), urinary tract infection (UTI), bladder infections, advanced cancer, blood clots, sexual problem in men, insomnia, and convulsions. Healthcare providers sometimes give forskolin intravenously (by IV) for heart failure. Some people breathe in (inhale) forskolin powder for asthma. Forskolin drops are used in the eyes to treat glaucoma. Because of its wide use, this plant some time been adulterated with its species and other varieties. The standardisation parameters are important for this plant in every herbal formulation. With the developments in modern instrumental methods it is high time for the herbal drug manufacturers to come out with the standard level of this drug to be included in the formulation. An extensive study of phytochemical constituents...
