ICH Q3C (R7) Residual solvents
Please note that the document has been corrected with a new PDE value for ethyleneglycol. Drug products should contain no higher levels ichh residual solvents than can be supported by safety data.
Ideally, less toxic solvents Class 3, table below should be used where practical. Some solvents associated with less severe toxicity Class 2, table below should be limited in order to protect patients from potential adverse effects. Leave this field blank. View all 2 ratings.
In general, solvents are not completely removed by practical manufacturing techniques. It recommends use of less toxic solvents and describes levels considered to be toxicologically acceptable for some residual solvents. Keywords Organic solvent, impurity, guldelines, class, reporting levels, permitted daily exposure PDEtoxicological Description This document recommends acceptable amounts for residual solvents in pharmaceuticals for the safety of the patient.

This document recommends acceptable amounts for residual solvents in pharmaceuticals for the safety of the patient. Appropriate selection of solvent for processing of a drug substance may enhance the yield, allow isolation of a preferred crystal form, improve purity, or enhance solubility.
Given the presence of solvents in most pharmaceutical processing steps, the content of solvents in pharmaceutical products should be evaluated.
Human regulatory Overview Research and development Marketing authorisation Post-authorisation Herbal products. How useful was this page? 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. 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.
Marketing authorisation holders are encouraged to contact the relevant regulatory authorities in case medicinal products are impacted by the abovementioned correction.

Therefore, the solvent can play a critical role in the synthetic process. 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.
