Ethylhexylglycerin is an alkyl glyceryl ether. This means that the ethyl hexyl group is bound to glycerin at one end by an ether linkage. it has been used as a common ingredient in bath products, body and hand products, cleansing products, deodorants, eye makeup, foundations, hair care products and suntan products. The compound is synthesized by esterfication of 2-Ethylhexanol and epichlorohydrin, followed by ring opening reaction of epoxy positioned at 1st and 2nd carbon in the chemical structure. It was characterized by NMR, seven -CH2 (position 10, 11, 9, 8, 6, 4 and 2) carbons present at negative side. Tertiary carbons are present at chemical shifts 39 ppm and 70 ppm (position at 7 and 3) and primary carbons are present at chemical shifts 10 ppm and 13 ppm (position at 14 and 12). Both primary and tertiary carbons were found on the positive side of the spectrum. From FTIR studies, peak corresponding to -OH stretch is observed at 3,391 cm-1 and the -OH bending is seen at 1,111...

The sublingual delivery of drugs represents a continuing challenge, as well as an opportunity. In this study, a poly (lactic-co-glycolic acid) (PLGA) based Water-in-Oil-in-Water (w/o/w) double emulsion of nanoparticles was developed as potential platform technology, to generate sustained drug release profile and maximize the bioavailability of the glutathione (GSH). Two-level full factorial design was carried out based on different types and concentrations of the stabilizers used, and on varying sonication time. The optimal formulations were predicted with particle size of 232.57 ± 20.56 nm, zeta-potential of -12.33 ± 0.20 mV and entrapment efficiency of 77.04 ± 1.50%. Spherical particle morphology and uniform size was observed by scanning electron microscopy. Sustained release profile was achieved and the release kinetics was illustrated as a Korsmeyer – Peppas kinetic model. Moreover, in ex-vivo permeation studies, approximately 2-fold increase in the transmucosal permeation of GSH was achieved when PVA and carbopol were incorporated with the nanoparticulate delivery system, resulting in 21.9 ± 1.2% drug permeation and a permeation coefficient of (4.96 ± 0.36)...

A sensitive, simple, accurate and fast method for vitamin C and E determination in pure and drug formulations using spectrophotometric was developed. The developed method is based on the formation of the charge transfer complex via the reaction between vitamins and Fe+3 [FeNH4(SO4)2.12H2O] in the presence of K3Fe(CN)6 which lead the formation of a blue-greenish colored product that has a maximum absorption at λmax=743 nm. The optimum reaction conditions such as temperature, volume, reaction time and pH were studied. The linear dynamic range for the intensity versus vitamins concentrations are 0.05-28 and 0.5-28 μg/mL for vitamin C and E respectively, with LOD values of 0.01 and 0.09 μg/mL and LOQ values of 0.033 and 0.297 μg/mL. The correlation coefficient (R2) is 0.9993, while the percentage linearity (%R2) was 99.93%. %R.S.D for the repeatability (n=3) is < 0.3%. The method was applied successfully for the determination of vitamin C and E in pharmaceutical preparation. The new method can be accepted as an alternative analytical method for the determination of the...

: In traditional Ayurved, numbers of medicated ghee formulations are prescribed to regulate person’s cognitive functions. Vachadi ghrita [VG], a medicated ghee formulation is prescribed to maintain healthy process of intellect and memory. In recent experimental studies, positive action of VG on animal’s memory was proved. Thus to generate clinical evidence, the study was attempted to evaluate the therapeutic potential of VG on healthy individual’s memory using PGI memory scale test. Methods: Non randomized positive controlled clinical trial was carried out in ninety healthy individuals. Thirty participants from two groups received VG and Cow ghee respectively. Plain control group participants did not receive any drug. Drugs were administered orally in 10 g dose twice a day for continuous 30 days. PGI memory scale was used to analyze before and after treatment effects of drugs on learning and memory ability in healthy individuals. Results: The participants of Vachadi ghrita showed significant change in scores of PGI scale as compared to the participants of plain (p<0.01) and cow ghee groups (p<0.05)....

Aim and Objective: Drug utilization research help in identification of the clinical use of drugs in population and its impact on health care system and to evaluate the rational drug usage. To study prescription pattern, to evaluate the adherence to treatment guidelines in diabetic patients attending the medical outpatient department in a tertiary care teaching hospital. Drug utilization research help in identification of the clinical use of drugs in population and its impact on health care system. To select the rational use of drugs as a predominant technique for the utilization of selective drugs in diabetes mellitus patients. Methodology: A cross-sectional retrospective study was carried out for 6 months in diabetic patients in the General Medicine Department. Data of 280 patients were collected and evaluated. Results: Total 280 diabetes mellitus patients were admitted. In this study, almost all prescriptions were with polypharmacy. The pattern of drug prescription in diabetes mellitus shows that insulin (22.14%) was most frequently prescribed followed by glimepiride (16.78%) and metformin (8.21%). In sulfonylureas monotherapy are...
