# Residual Solvents Reports

Risk assessments for residual solvents in pharmaceutical products

QbD Group specializes in risk assessments for residual solvents in human and veterinary drug products, helping identify risks, generate comprehensive reports, and address regulatory concerns per ICH Q3C guidelines.

## What is residual solvent risk assessment?

Residual solvent risk assessment is a **comprehensive evaluation of drug substances, excipients, and manufacturing processes** aimed at identifying and mitigating risks associated with residual solvents. This process is designed to protect patients from potential adverse effects.

It includes three key steps:
- Analyzing potential residual solvents introduced during the manufacturing process.
- Evaluating actual or predicted solvent levels against established PDE values.
- Defining an effective control strategy based on the findings.

## The importance of managing residual solvents

According to the ICH Q3C guideline, residual solvents offer no therapeutic benefit and can pose potential risks to patient safety.

### Patient safety

Solvents must be removed to the greatest extent possible to protect patients.

### Regulatory compliance

Meet product specifications, GMP, and other quality-based requirements.

### Audit readiness

Updated, documented repository ensures preparedness for regulatory inspections.

### Product quality

Maintain product integrity throughout the manufacturing process.
