In 2002, 42% of these products failed to comply with compendial specifications, with the sulfadoxine/ sulfamethoxypyrazine and pyrimethamine combination products forming 39% of the total failures. The respective percentages were 46% and 84% for 2003 and 36% and 72% for 2004. By May 2005, the only failures reported were of sulfadoxine/sulfamethoxypyrazine and pyrimethamine combination products. Until recently, sulfadoxine/sulfamethoxypyrazine and pyrimethamine combination products were the first-line malaria treatment regimen in Kenya. These analytical results raise concerns that the reported therapeutic failures associated with the use of these products could possibly be due to the administration of sub-standard sulfadoxine/sulfamethoxypyrazine and pyrimethamine combination products to patients. The same could be true of artemisinin based combinations which are the current first-line treatment regimen if the observed trend continues Keywords : Antimalarials, dissolution, assay, quality control tests East and Central African Journal of Pharmaceutical Sciences Vol. 10 (3) 2007: pp. 59-62","PeriodicalId":22387,"journal":{"name":"The East and Central African Journal of Pharmaceutical Sciences","volume":"14 1","pages":"59-62"},"PeriodicalIF":0.0,"publicationDate":"2008-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82053025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pH of the dissolution medium was found to affect propranolol hydrochloride release from such matrices. Acidic pH was found to enhance release while alkaline pH retarded release. This was attributed to possibly the effect of gum tragacanth matrix material or the propranolol hydrochloride itself. Either square root of time kinetics or first order kinetics could explain propranolol hydrochloride release mechanism from the hydrogenated castor oil–gum tragacanth matrices. Addition of hydrophobic hydrogenated castor oil matrix material to the hydrophilic gum tragacanth matrix was found to enhance release. This was attributed to possibly the disruption of the gum tragacanth matrix by the hydrophobic hydrogenated castor oil matrix material. Although gum tragacanth is primarily a hydrophilic material, it was found to have better release sustaining characteristics than the hydrophobic matrix material hydrogenated castor oil.
