What is ICH limit?
The stated limit of 1500 ppm is based on a review of the safety data. TABLE 1. Class 1 solvents in pharmaceutical products (solvents that should be avoided). Solvents in Table 2 should be limited in pharmaceutical products because of their inherent toxicity.
What is PDE mg day?
The PDE in terms of mg/day as stated in Table 2 can be used with the known maximum daily dose and equation (1) above to determine the concentration of residual solvent allowed in drug product.
What is a Class 3 solvent?
Solvents in Class 3 (Table 3) may be regarded as less toxic and of lower risk to human health. Class 3 includes no solvent known as a human health hazard at levels normally accepted in pharmaceuticals. However, there are no long-term toxicity or carcinogenicity studies for many of the solvents in Class 3.
What is a Class 1 solvent?
Class 1 includes the solvents considered to be the most toxic, such that their use should be avoided in the production of pharmaceutical products. These chemicals are: benzene, carbon tetrachloride, 1,2-dichloroethane, 1,1-dichloroethene and 1,1,1-trichloroethane (the latter owing to its environmental impact).

- Q1F – Stability Data Package for Registration Application in Climatic Zones III and IV.
- Q2 (R1) – Validation of Analytical Procedures : Text and Methodology.
- Q3B (R2) – Impurities in New Drug Products.
- Q3C (R5) – Impurities : Guideline for Residual Solvents.
How is PDE value calculated?
According to EMA guideline, the equation used to calculate PDE is:
- PDE = (NOAEL x Weight Adjustment) / (F1 x F2 x F3 x F4 x F5)
- F3 = A variable factor to account for toxicity studies of short-term exposure.
- and F4.
What does USP 467 mean?
(Current chapter title is (467) Organic Volatile Impurities) For pharmacopeial purposes, residual solvents in pharmaceuticals are defined as organic volatile chemicals that are used or produced in the manufacture of drug substances or excipients, or in the preparation of drug products.
Is isopropyl alcohol a Class 3 solvent?
Isopropyl Alcohol (Isopropanol, IPA) itself would be considered a Class 3 residual solvent if found in any other solvent.
What is residual solvent in GC?
Residual solvents in pharmaceuticals are defined here as organic volatile chemicals that are used or produced in the manufacture of drug substances or excipients, or in the preparation of drug products. The solvents are not completely removed by practical manufacturing techniques.
