4.2 What is the magnitude of the problem?
The data presented in this report indicate that there is a significant problem of substandard antimalarial drug products circulating in the markets of the participating countries. The most significant results were the low content failures for CQT (ranging from a low of 5.2% in Sudan to a high of 66.7% in Ghana) and SPT dissolution (ranging from a low of 75% in Ghana to 100% for Mali, Mozambique and Zimbabwe). However, as this study faced a number of logistical problems, i.e. sample containers, sample quantities, labelling and coding, these results can only be taken as indicative, but not conclusive.
