1. Enhanced Drug Solubility: Poorly water-soluble drugs can be formulated as nanostructures to improve their solubility and absorption. 2. Targeted Delivery: Nanocarriers can be engineered to deliver drugs precisely to diseased cells, reducing off-target effects. 3. Controlled Release: Nanostructured drugs can be designed for sustained and controlled release, ensuring a consistent therapeutic effect over time. 4. Reduced Toxicity: By localizing the drug action, nanostructured drugs can reduce systemic toxicity and adverse effects.
