Lack of quality medicines leads to drug resistance.

Most drug quality assurance systems are weak. This can lead to poor quality medicines, exposing patients to sub-optimal concentrations of antimicrobials, thus creating the conditions for drug resistance to develop. In some countries poor access to antimicrobials forces patients to take incomplete courses of treatment or to seek alternatives that could include substandard medicines.
