The future of dermatological safety: FDA’s new approach to predicting dermal sensitisation

Traditional methods for evaluating the immunotoxic potential of pharmaceuticals typically involve animal testing, which is time-consuming, costly, and raises ethical concerns. In response to these challenges, regulatory agencies, including the Food and Drug Administration (FDA), are actively encouraging the development and acceptance of alternative methods. FDA’s new guidance on dermal sensitisation The FDA has recently
