Poor quality antimalarial drugs are one of the public’s major health problems in Africa. The depth of this
problem may be explained in part by the lack of effective enforcement and the lack of efficient local drug
analysis laboratories. To tackle part of this issue, two spectroscopic methods with the ability to detect and
to quantify quinine dihydrochloride in children’s oral drops formulations were developed and validated.
Raman and near infrared (NIR) spectroscopy were selected for the drug analysis due to their low cost,
non-destructive and rapid characteristics. Both of the methods developed were successfully validated
using the total error approach in the range of 50–150% of the target concentration (20% W/V) within the
10% acceptance limits. Samples collected on the Congolese pharmaceutical market were analyzed by both
techniques to detect potentially substandard drugs. After a comparison of the analytical performance of
both methods, it has been decided to implement the method based on NIR spectroscopy to perform the
routine analysis of quinine oral drop samples in the Quality Control Laboratory of Drugs at the University
of Kinshasa (DRC). |
