The prevalence of self-medication with medicines including herbs in urban areas of Khartoum State is high. Self-medication behaviour varies significantly with a number of socio-economic characteristics. Our findings have major public health policy implications for countries like Sudan.

The prevalence of self-medication with antibiotics/antimalarials among undergraduate university students in Khartoum State is high. Our findings highlight the need for planning interventions to promote the judicious use of antibiotics/antimicrobials.

Inappropriate prescribing patterns of antibiotics in health centers of Khartoum State, Sudan, are alarmingly high. Multifaceted interventions involving audit and feedback combined with either academic detailing or seminars appear more effective in changing prescribing practices of antibiotics than audit and feedback alone.

Abstract. Documentation on the efficacy of artesunate in Africa is limited, and no experience of artesunate use in Sudan is documented. Severe malaria in rural areas of Sudan, where facilities for the safe and effective use of parenteral quinine are lacking, is a frequent problem. Early treatment with artesunate suppositories would provide a simple method for use by unskilled staff and would be an alternative approach to treat malaria in settings with poor resources. We describe a hospital-based study of rectal artesunate in 100 adult patients with severe falciparum malaria with a dose derived from pharmacokinetic data (200 mg every 8 hours) over 3 days, which halted progression of severe disease and had a low fatality rate. The dosage schedule led to a rapid clinical response and reduced parasite clearance and fever subsidence times of (31.5 ± 10

The aims of this study were to determine the pharmacokinetic parameters of a single dose of 200 mg oral and rectal artesunate in healthy volunteers, and to suggest a rational dosage regimen for rectal administration. The study design was a randomized open cross-over study of 12 healthy volunteers; the analytical method used was a reversed phase high performance liquid chromatography with post column derivatization and subsequent ultraviolet detection. Pharmacokinetic parameters were derived from the main metabolite alpha-dihydroartemisinin data due to the rapid disappearance of artesunate from the plasma. Dihydroartemisinin following oral administration of artesunate had a significantly higher AUC(0-infinity) (P<0.05 95% confidence interval (CI) -1168.73, -667.61 ng x h/mL(-1)) and Cmax (P<0.05; 95% CI -419.73, -171.44 ng/mL(-1)), and had shorter tmax (P<0.05; 95% CI -0.97, -0.10 h) than that following rectal artesunate. There was no statistically significant difference in the elimination half-life between both routes of administration (P>0.05; 95% CI -0.14, 0.53 h). The relative bioavailability of rectal artesunate was [mean (coefficient of variation %) 54.9 (24.8%) %]. On the basis of these data an 8 hourly dosing regimen per day with rectal artesunate is proposed.

Our findings showed that artemether-lumefantrine was an effective and safe drug for treating uncomplicated P. falciparum malaria in northern and southern Sudan.
