Microneedle

Abstract Olanzapine (OLZ) is classified as a typical antipsychotic drug utilized for treatment of schizophrenia, it possesses poor oral bioavailability (60%) due to low solubility and first-pass hepatic metabolism. Hence, the aim of present work is to fabricate and evaluate an olanzapine…

Abstract To address incomplete drug release in monolithic dissolving microneedle (DMN) patches caused by non-selective drug dispersion into the backing layer, this study employs the lance-inspired architecture to develop a lance-microneedle (LMN) patch. The LMN patch features a decoupled microshaft…

Abstract Imidafenacin tablets are the first-line drug for the treatment of overactive bladder (OAB). However, the tablets need to be taken twice daily for up to 3–6 months, which highly reduces patient compliance. This study aimed to develop a long-acting imidafenacin transdermal patch (LAITP) with…
