A Review On Transdermal Drug Delivery System For Antifungal Agent Terbinafine

Fungal skin problems aren't rare. Not even close. Most of the time they stay on the surface—think the epidermis, hard keratin areas like nails and hair, and those moist mucosal zones that fungi seem to love. You'll keep running into the usual suspects: dermatophytosis, Candida infections on skin or mucosa, pityriasis-type eruptions, plus a grab bag of region-linked conditions that show up a lot in places like Malaysia. The share of cases they take up is… big.And yes, we've got plenty of antifungal drugs. That doesn't mean treatment is smooth. People miss doses because dosing is too frequent. Medication doesn't always "stick" where it's needed. Absorption can be all over the map. Side effects turn some patients off fast. Resistance? It's not theoretical anymore. So researchers keep circling back to one question: how do you get the drug where it matters, keep it there, and make the whole routine easier to live with?That's where transdermal delivery starts looking tempting. A patch is non-invasive. It can drip-feed a medication at a controlled pace. Effects can last longer. You also dodge the stomach and the liver's first-pass metabolism, which can chew up certain compounds before they do much good.But here's the catch. Skin is stubborn. The stratum corneum is basically a bouncer at the door, and most drug molecules don't get past it without a fight. So building an antifungal patch isn't just "mix drug + stick-on backing." You have to choose the right drug candidate, the right polymer base, the right permeation boosters, plasticizers, and whatever else the formulation needs so release stays predictable and penetration actually happens.Both classic synthetic antifungals and bioactive compounds pulled from natural sources have shown they can work in these patch-style systems. The newer designs get more creative too: polymer matrices tuned for steady release, chemical or plant-based permeation enhancers, nanocarrier-assisted setups, and other tweaks meant to push more drug into the right layer and keep it there longer. Put it all together and the idea is pretty straightforward—pair antifungal therapy with transdermal tech, and you may end up with a safer, more convenient, longer-lasting way to manage fungal infections of the skin.‍‍‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌
