Emerging Trends in Biomarker-Guided Drug Delivery for Improved Oral Bioavailability

Biomarker-based medication delivery is a novel method to precision medicine that targets therapy using biological indicators to optimize dose and timing. This technology provides tailored therapies by leveraging physiological or molecular signatures, which improves efficacy and safety. Although oral drug delivery is recommended for compliance, variables such as poor solubility and enzymatic degradation reduce bioavailability, resulting in varying effects. Biomarker guidance helps to address these challenges by targeted release and real-time dose changes. Recent breakthroughs include pH-sensitive formulations and responsive nanocarriers, which show promise in oncology and metabolic illnesses. However, greater clinical applications necessitate biomarker validation, scalable manufacturing, and regulatory alignment. Future integration with technology such as artificial intelligence and wearable sensors could further customize and improve oral medicines.
