ASPICon2023 will run on the theme “Precision Clinical Pharmacology: Future of Rational Therapeutics”. A rising number of adverse drug reactions (ADRs) has led to unplanned hospital admission or readmission of patients, with a drug–drug interaction suspected in many cases. Therefore, significant efforts are being made to refine personalized, precise, predictive, and participatory therapeutic strategies that can be systematically defined as precision or personalized medicine. The adoption of precision medicine practices in hospitals requires the interaction of different medical disciplines, including clinical pharmacology.
