Research Article Pharmacy Practice GELLIFIED EMULSION FOR SUSTAIN DELIVERY OF ASPIRIN AS ANTI-INFLAMMATORY INTRODUCTION Aspirin is a non-steroidal anti-inflammation drug (NSAID). It widely use as analgesic in treating mild to moderate pain such as injury, headache, arthritis, menstrual cramp and other musculoskeletal condition. Aspirin is an ester of salicylic acid, while after ingestion it will undergoes hydrolysis which produce salicylic acid and acetic acid. Salicylic acid…

Problem Statement Industries are generated waste water, which contain dyes and pigments in waste water. Characteristically high in colour and organic content (Grag, et al., 2004). Dyes are widely used in industries such as textile, rubber, paper, plastic, and cosmetic. There are many of dyes exist in industries and one of them is methyl red and through nano zerovalent iron removal of dyes from waste water. Dye industry effluents constitute one of the most problematic wastewaters to be treated…

I. Introduction The human respiratory system allows cells to have indirect contact with the external environment through gas exchange. This association permits cells to exchange metabolic by-products like carbon dioxide for oxygen. These oxygen molecules are a vital component for cellular metabolism and ATP production. Furthermore, the function of the respiratory system also encompasses homeostatic regulation of pH levels based on partial pressure of oxygen and carbon dioxide. Changes are…

”) So this means detergent can work as a surfactant. Detergent molecules also carry elements of hydrophilic portions,…

a relatively low content of residual oil, which is largely depends on demulsifier flow rate: it reduction led to the growth of the oil content in the drainage water. The demulsifier almost no goes into the aqueous phase, as evidenced by the low surfactant content in the drainage water…

involved in the extraction of the biomolecule from the crude is extremely economical. The RME system is greatly influenced by a number of parameters such as the pH, the type of salt used and its concentration, the type of solvent used, the type of surfactant used and its concentration, water content and volume ratio of the aqueous phase to the organic phase (Liu et al, 2008). The diffusion of biomolecules inside the micelles is governed by electrostatic, steric and hydrophobic interactions…

With regards to cleansing soap and water is not advised for skin cleansing post-incontinence, soap adversely affects the skin by removing natural oils which results in dryness. Thus making the skin more vulnerable. The majority of soaps and cleansers are alkaline, with a pH around 9, and when used routinely to cleanse the skin of patients with incontinence these can affect the skin’s acid mantle (Kirsner and Froelich, 1998). The pH of the skin normally is 4.5 – 6.2, which creates the acid mantle…

pharmaceutical use, NPs can be of polymeric nature or be made of lipophilic components plus surfactants, i.e., liposomes, niosomes, and solid lipid NPs. Other materials investigated for NPs preparation are albumin [16], gelatin[17] ,or calcium alginate[18]. There are also several methods available to size-reduce drug substances into the nanometer range, with the produced NPs being stabilized by surfactants[19, 20]. Albumin can form layers on NP, which are stabilized by denaturation of the…

Neonatal care is a huge issue in the United States. Neonatal care has rescued so many premature babies over the years due to the new technology that has been made. Many people believe that neonatal care is a great priority and some people are apposed to this idea, that these children aren 't even worth saving. Neonatal care is the care of premature or ill newborn infants. The issue of premature and ill infants isn 't a new problem. It wasn 't until 1922 that hospitals started grouping these…
