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.


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. Return to top of page. It recommends use of less toxic solvents and describes levels considered to be toxicologically acceptable for some residual solvents.

Given the presence of solvents in most pharmaceutical processing steps, the content of solvents in pharmaceutical products should be evaluated.

Residual Solvents Under USP (ICH Q3C) Guidelines

Appropriate qc3 of solvent for processing of a drug substance may enhance the yield, allow isolation of a preferred crystal form, improve purity, or enhance solubility. Residual solvents in pharmaceuticals are defined by the ICH as organic volatile chemicals that are guidrlines or produced in the manufacture of drug substances, excipients, or in the preparation of drug products.


Documents to be published. Some solvents associated with less severe toxicity Class 2, table below should be limited in order to protect patients from potential adverse effects.
