Personalized therapeutics focuses on designing and selecting treatments based on an individual's unique genetic, molecular, and clinical characteristics. Rather than relying on standardized therapies, this approach tailors medications, dosages, and treatment plans to optimize effectiveness and reduce adverse effects. By integrating genomic profiling, pharmacogenomics, biomarker analysis, and digital health tools, personalized therapeutics offers targeted interventions for conditions such as cancer, autoimmune disorders, infectious diseases, and chronic illnesses. This strategy enables clinicians to match therapies with patient-specific biological pathways, improving treatment responses and long-term outcomes. Personalized therapeutics also supports adaptive treatment planning as new molecular information emerges.
