Abstract

Microneedles have emerged as a groundbreaking technology for drug delivery, offering painless and precise administration of therapeutic agents. These micron-sized needles penetrate the outermost barrier of the skin, enabling the direct delivery of medications to underlying tissues and bloodstream. This paper explores the development, design, and applications of microneedles in drug delivery systems. By bypassing the pain receptors in the skin, microneedles eliminate the discomfort associated with traditional injections, making them a patientfriendly alternative. The precise control over drug release achieved through microneedle-based systems enhances therapeutic outcomes and reduces potential side effects. This review summarizes recent advancements in microneedle technology, discusses their potential impact on various medical fields, and addresses challenges in large-scale manufacturing and regulatory approval. With the potential to revolutionize drug delivery, microneedles pave the way for more effective and patient-compliant medical treatments.
