Introduction for Permitted Daily Exposure for Aceclofenac:
The Permitted Daily Exposure (PDE) assessment for Aceclofenac establishes a health-based exposure limit using available pharmacological, pharmacokinetic, clinical, and toxicological information. Aceclofenac is an NSAID used for pain and inflammation and acts mainly through cyclooxygenase inhibition. The assessment reviews acute toxicity, carcinogenicity, genotoxicity, reproductive and developmental toxicity, sensitization potential, and clinical adverse effects. A minimum therapeutic dose of 2 mg/kg/day was considered as the NOAEL. Using a 50 kg body weight and adjustment factors F1=1, F2=10, F3=10, F4=1, and F5=5, the calculated PDE for Aceclofenac is 0.2 mg/day, supporting cross-contamination risk assessment and cleaning limit calculations in shared manufacturing facilities.

The flow diagram illustrates the systematic approach for establishing the Permitted Daily Exposure (PDE) of Aceclofenac. It begins with collection and review of pharmacological, toxicological, pharmacokinetic, and clinical data. The next steps include hazard identification, selection of the critical effect, and determination of the point of departure using a NOAEL of 2 mg/kg/day. Appropriate assessment factors are then applied to account for variability and uncertainty. Using a body weight of 50 kg and factors F1=1, F2=10, F3=10, F4=1, and F5=5, the final calculated PDE for Aceclofenac is 0.2 mg/day.
3. Brainstorming for Permitted Daily Exposure of Aceclofenac:
The brainstorming diagram summarizes the key elements considered while establishing the Permitted Daily Exposure (PDE) for Aceclofenac. It covers the objective of defining a health-based exposure limit, review of pharmacological, toxicological, pharmacokinetic, and clinical data, identification of potential hazards, and evaluation of critical effects. The diagram highlights the selected NOAEL of 2 mg/kg/day, a standard body weight of 50 kg, and the applicable adjustment factors. Using these inputs in the PDE formula, the calculated exposure limit is 0.2 mg/day. The resulting PDE can support cleaning validation, cross-contamination risk assessment, and shared-facility control strategies.
