Objective To evaluate the practices of university students towards self-medication to treat minor ailments in Muscat and Sohar region of Sultanate of Oman. Methods A cross sectional study was conducted in October 2013-January 2014. A total of 450 university students were randomly selected and their verbal consent was obtained. The data were collected through the self-administered, close ended, pretested questionnaire and was analyzed statistically by SPSS version 19.0. Results Overall 204 males (45.3%) and 246 females (56.7%) participated in the study. The mean age of respondents was 22.3 years. Ninety-four percent of respondents reported practicing self-medication and 165 (36.7%) participants admitted of having purchased drugs without prescription more than four times over the last six months. Headache, fever, cough and cold were the most common ailments which prompted respondents to seek self-medication. Analgesics, cough preparations and antibiotics were the most common classes of drugs used in self-medication. The majority of respondents practiced self-medication either because their illness was not serious or they had prior experience with the drug. The majority of respondents had good medication knowledge which they reported to acquire from reading drug leaflet or from pharmacists' advice. Conclusion The prevalence of self-medication among university students was very high. There is a need for intensive education and comprehensive awareness campaign to advocate for reduction in the prevalence of self-medication practices among students. [ABSTRACT FROM AUTHOR]

Objective To perform phytochemical screening and to evaluate the in-vitro antioxidant and anti-inflammatory activities of ethanolic extract of seeds and fruits of Zizyphus spina-christi (ZSC) growing in Oman. Methods Alcoholic extract of the dry powdered seeds and fruits of ZSC was obtained by cold maceration method and was subjected to preliminary phytochemical screening. Total phenolic content were estimated by using Folin-Ciocalteu reagent and 1,1-diphenyl-2-picrylhydrazyl (DPPH) was used to determine in-vitro antioxidant activity of plant extracts. Anti-inflammatory activity was investigated by protein denaturation method. Results Phytochemical analysis of both the extracts revealed the presence of major classes of phytochemicals such as tannins, alkaloids, flavonoids, cardiac glycosides etc.. ZSC seeds were found to contain the highest total phenolics but ZSC fruits exhibited the maximum antioxidant activity. The anti-inflammatory activity of both parts of the plant extract was significant and comparable with the standard anti-inflammatory drug, diclofenac. Conclusions Based on the results of this pilot study, it can be concluded that ZSC is a good source of natural antioxidants which can be used to prevent progression of many chronic diseases. Further detailed phytochemical studies are needed to identify the chemical compounds responsible for exhibiting potent anti-inflammatory activity. [ABSTRACT FROM AUTHOR]
