Microneedles were first conceptualized for drug delivery many decades ago, overcoming the shortages and preserving the advantages of hypodermic needle and conventional transdermal drug-delivery systems to some extent. Dissolving and biodegradable microneedle technologies have been used for transdermal sustained deliveries of different drugs and vaccines. This review describes microneedle geomet...

Most of the therapeutic agents are recommended through an oral route, but oral route has disadvantages like first pass metabolism, liver toxicity, etc, due to gastrointestinal pH. This leads poor bioavailability of drugs, which are not stable in G.I pH. To overcome this problem, increase the bioiavailibility, reduce the dose and dose dumping Transdermal delivery system is better option as novel...

Worldwide prevalence of type 2 diabetes is increasing with alarming proportions. Metformin is the first-line oral antidiabetic drug of choice for the treatment of type 2 diabetes. The objectives of the present study were to develop Metformin solid lipid nanoparticles (M-SLN) and incorporate it in the transdermal patches. M-SLN was evaluated for Particle size, Zeta potential, Surface morphology ...

In this study, the transdermal drug delivery properties of D,L-tetrahydropalmatine (THP)-loaded amphiphilic poly{[alpha-maleic anhydride-omega-methoxy-poly(ethylene glycol)]-co-(ethyl cyanoacrylate)} (PEGECA) graft copolymer nanoparticles (PEGECAT NPs) were evaluated by skin penetration experiments in vitro. The transdermal permeation experiments in vitro were carried out in Franz diffusion cel...

Transdermal and dermal drug delivery is problematic because the skin, as a natural barrier, has a very low permeation rate. Therefore several methods have been assessed to increase this rate locally and temporarily. One approach is the use of vesicle formulations. In this paper the effectiveness of conventional and deformable vesicles as drug delivery systems as well as their possible mode of a...
