Drug Delivery Routes and Challenges at PDDS 2027

Drug delivery routes and challenges play a significant role in determining the effectiveness of pharmaceutical treatments. Different routes, such as oral, intravenous, transdermal, and inhalational, offer unique benefits but also come with specific obstacles. Oral delivery is widely used for its convenience but is often hindered by issues like poor bioavailability and first-pass metabolism. Intravenous routes provide rapid action, though they require professional administration and carry infection risks. Transdermal delivery offers controlled, long-term release but faces limitations related to skin permeability. Inhalational routes are effective for targeting the lungs but present challenges in dosing accuracy and formulation stability. Each of these Drug Delivery Routes and Challenges requires innovative solutions to improve drug efficacy, safety, and patient adherence, with advances in targeted and nanotechnology-based drug delivery systems helping to overcome many of these barriers.
