İğnenin Ötesinde: Mikroiğne İlaç Dağıtım Sistemleri ile Geleneksel Sağlık Hizmetlerinin Dönüşümü

Özet (abstract)

In the present era, modern drug delivery systems play a fundamental role in ensuring the systematic delivery of the drug into the body, reaching the desired targets. Across recent decades, the drug delivery system has evolved from simple oral and injectable formulations to interpolating with various developed techniques to fabricate innovative treatment approaches for safer, effective, and better patient compliance. Progressive techniques like nanoparticles, microparticles, liposomes, polymer-based systems, 3D printing, and biological carriers have been extensively combined with specifically targeted drug-delivery techniques across infectious, oncological, pulmonary, and neurological conditions. Microneedle transdermal patches have advanced in tandem. They have gained attention for their advancement to surpass the stratum corneum, minimal invasiveness, independent delivery, and patient compliance. This review provides a translational perspective by integrating MN materials and device engineering with drug-delivery performance, patient usability, clinical evidence, manufacturing scalability, and regulatory considerations to examine the progression of MN technologies from laboratory development toward real-world healthcare implementation. Microneedles are fabricated in different types, such as solid, coated, hollow, dissolving, and hydrogel-based, to enhance precision in dosing, better permeability, and suitability across diverse populations, and complex molecules are designed, such as proteins, peptides, hormones, vaccines, and cosmetic agents. Moreover, studies suggest MN are widely accepted by geriatric and pediatric groups, reduce anxiety, and significantly benefit individuals with trypanophobia, swallowing difficulties in the case of oral doses, and compromised venous action, in addition to breaking social inequity. MN-induced microchannels can transiently increase skin permeability and may facilitate sustained or controlled drug delivery depending on MN geometry, formulation, application conditions, skin site, and individual skin characteristics. The persistence of these microchannels and their safety profile are dependent on both device and formulation characteristics. MN is a pivotal part of the novel drug delivery system, addresses the complications arising due to conventional drug delivery, and proves to focus on the improvement of pharmacokinetic parameters, patient-centric therapy, target delivery, and real-world accessibility. Further transformation in the enhancement of MN technology can lead to clinically promising drug delivery systems for the management of long-term treatment and boost next-generation therapies.
