Chemical drugs have a low molecular weight and derive from a production process based on chemical synthesis starting from compounds which, under defined conditions, give rise to pharmacologically active molecules. Generally, the drug is chemically characterized in depth and its use takes place with a dosage expressed by weight.
In the context of problems related to chemical drugs, whether for human or veterinary use, checks and assessments are carried out at the Italian and European level, as well as a whole series of other pharmacosurveillance and pharmacoepidemiology activities by the Istituto Superiore di Sanità (ISS, the National Institute of Health in Italy).
