Nigeria and many countries in the world have been plagued by counterfeit and poor-quality medicines with several studies indicating varying degree of prevalence.
The study is aimed at determining the anticounterfeiting strategies employed by local drug manufacturers in Lagos, Nigeria.
The first phase was a descriptive study which involves the use of a self-administered closed ended structured questionnaire to assess the anticounterfeiting strategies employed by local manufacturers in Nigeria. The second phase was an experimental study which selected 2 classes of most frequently faked drugs identified by the respondents in the first phase (antimalarials and antibiotics) and subjected to spot checks using the Truscan analysis deployed by NAFDAC to identify counterfeit medicines. Anticounterfeiting features on the samples were also examined. The data obtained from phase one was analyzed using SPSS while the data obtained from phase 2 was entered into the Truscan data sheet and analyzed using Chi-squared. Results were considered to be significant at P<0.05.
The anticounterfeiting technologies indicated by the respondents as the highest in the first phase were Sequential Batch Numbering 61.1 % (overt) and Bar Codes 29.0 % (covert). While the second phase revealed that 83% and 78% of antimalarials drawn from the manufacturing sources and open market respectively passed the Truscan spot checks. Similarly, 50% of antibiotics drawn from the 2 sampling sites passed the Truscan checks. There was no significant difference (P>0.05) between the sampled antimalarials and antibiotics from the manufacturing sources and open market.
