Residual Solvents Under USP (ICH Q3C) Guidelines
View all 2 ratings. 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. 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 icb justified in a risk-benefit assessment.
In general, solvents are not completely removed by practical manufacturing techniques. Leave this field blank.

Veterinary regulatory Overview Research and development Marketing authorisation Post-authorisation. High priority sample services available with next-day turn around.
Appropriate selection of solvent for processing of a drug substance q33c enhance the yield, allow isolation of a preferred crystal form, improve purity, or enhance solubility. Drug products should contain no higher levels of residual solvents than can be supported by safety data. Please note that the document has been corrected with a new PDE value for ethyleneglycol. How useful was this page? Given the presence of solvents in most pharmaceutical processing steps, the content of solvents in pharmaceutical products should be evaluated.
Keywords Organic solvent, impurity, limits, class, reporting levels, permitted daily exposure PDEtoxicological Description This document recommends acceptable amounts for residual solvents in pharmaceuticals for the safety of the patient.
ICH Q3C (R7) Residual solvents
It recommends use q3cc less toxic solvents and describes levels considered to be toxicologically acceptable for some residual solvents. 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.
Marketing authorisation holders are encouraged to contact the relevant regulatory authorities in case medicinal products are impacted by the abovementioned correction. 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.
