Microneedle Technology: An Overview Focusing on its Types, Drug and Hormonal Delivery System in Animals

Microneedle technology has garnered significant attention in the biomedical field as a minimally invasive drug delivery system emphasized by exponential increase in the rate of academic publications in this era. Its application in veterinary medicine is emerging as a promising tool, particularly in the delivery of drugs and hormones such as progesterone, insulin, Human growth hormone etc. This review explores different types of microneedles and their use in drug and hormonal delivery systems for animals. Also, the mechanisms, benefits, challenges, and future prospects of using microneedles for drug and hormonal administration in veterinary applications has been discussed briefly. A bird eye view on all these aspects strongly aided our scientists and technocrats to tackle the obstacles in drug and hormonal delivery system more wisely, precisely and efficiently
