The most toxic solvents Class 1, table below should be avoided in the production of drug substances, excipients, or drug products unless their use can be strongly justified in a risk-benefit assessment. Ideally, less toxic solvents Class 3, table below should be used where practical.
This document recommends acceptable amounts for residual solvents in pharmaceuticals for the safety of the patient. Some solvents associated with less severe toxicity Class 2, table below should be limited in order to protect patients from potential adverse effects.
Read together with the annexes on specifications for class 1 and class 2 residual solvents in active substances and residues of solvents used in the manufacture of finished products.

Impurities: Guideline for Residual Solvents
Return to top of page. Documents to be published. Solvents provide no therapeutic benefit, therefor all residual solvents should be removed to the extent possible to meet product specifications, good manufacturing practices, or other quality-based requirements.
Drug products should contain no higher levels of residual solvents than can be supported by safety data. Given the presence of solvents in most pharmaceutical processing steps, the content of solvents in pharmaceutical products should be evaluated.

Please note that the document has been corrected with a new PDE value for ethyleneglycol.
Marketing authorisation holders are encouraged to contact the relevant regulatory authorities in case ghidelines products are impacted by the abovementioned correction. Leave this field blank. Residual solvents in pharmaceuticals are defined by the ICH as organic volatile chemicals that are used or produced in the manufacture of drug substances, excipients, or in the preparation of drug products. In general, solvents are not completely removed by practical manufacturing techniques.
