Results for the content analysis are expressed as a percentage of the detected api in a given sample from the stated dose on the packaging. The protocols outline the details of the test conditions (dissolution buffersolvents, stirring speed, tolerance levels of the api, and temperature for the assay). One sample from nigeria passed the minilab tlc test but was found to be noncompliant by hplc content analysis.
Definitive drug quality was measured using high-performance liquid chromatographyphotodiode array detection (hplc-pda) for content of the stated active pharmaceutical ingredients (apis) and bioavailability was determined with in vitro dissolution testing.

A study carried out of antibiotics purchased in the middle east and north africa found that there was a substantial amount of locally produced amoxicillin that did not comply with drug monographs in the u. We are also grateful to elizabeth louise allan for her valuable comments on this manuscript. Therefore, the minilab cannot be relied upon unequivocally for drug quality monitoring, and for definitive results precise analytical methods such as hplc and dissolution testing need to be utilized. One co-trimoxazole tablet (obtained in the united kingdom) was compliant with the content analysis test, while 14 samples purchased in ghana and nigeria were not. We were not successful in obtaining the original packets of generics from manufacturers to help us to compare and distinguish any differences.
Their quality was assessed using german pharma health fund (gphf) minilab as the screening tooltwo capsules of amoxicillin (10) and two tablets of co-trimoxazole (20) failed the thin-layer chromatography (tlc) test. Similarly for a drug to be classified as pass using the tlc test, the spot of the sample should migrate at the same rate as that for the working standard solution 80 of the api, which represents the lowest acceptable limit. This underestimation of poor quality using the tlc test demonstrates the lack of accuracy of the minilab to detect noncompliant samples of certain drugs such as co-trimoxazole in this study.

Studies with larger sample sizes need to be undertaken with a number of the main classes of anti-infective drugs to determine the sensitivity and specificity of the minilab notably no falsified samples were identified in this study, even though the sample size was small, but substandard co-trimoxazole samples containing less than 93 apis have been detected.
Thirty five samples (27 brands) of the antibiotics amoxicillin ( 15 11 brands), manufactured in six countries (china, ghana, india, ireland, nigeria, and united kingdom), were purchased in ghana, nigeria, and the united kingdom. Peak identity of amoxicillin, sulfamethoxazole, and trimethoprim was confirmed by measuring the retention time, spiking the sample with commercially available standards and determination of absorbance spectra using the uv-pda. All 20 samples of amoxicillin produced the dark red-brown solution as per the minilab manual for each of these drugs and were classified as pass whereas two samples, purchased in ghana, failed the tlc test ( ). These subtherapeutic tablets were all bought in ghana and nigeria, stating that they were manufactured in those countries, except for one that states it was manufactured in india. The dissolution tests require sophisticated apparatus as well as the analytical equipment such as hplc, and most crucially the latter analysis requires the reference standards of the compounds being tested for calibrating the equipment, which can be both expensive and difficult to obtain. Dissolution tests measure the amount of drug released into the dissolution media with time following detailed protocols (official monographs) set out for most drugs in pharmacopeias (e.
