Thereafter a consensus procedure among international experts was undertaken to develop statements to support clinical decision making, in terms of possible effects on migraine course of exogenous estrogens and progestogens and on possible treatment of headache associated with the use or with the withdrawal of hormones. Overall, quality of current evidence is low. Recomm...

Development of Drug-in-Adhesive Patch with a Honeycomb Film as a Backing Layer.

Excess stripping of stratum corneum (SC) layers by patch-peeling from the skin surface is one cause of skin irritation. High SC hydration by patch occlusion may also cause skin irritation, although the occlusive technique is preferable to increase the skin permeation of topically applied drugs. In the present study, film having a honeycomb structure was selected as the backing layer of a drug-in-adhesive (DIA) patch to reduce peeling of the SC without losing adhesion force to the skin surface, as well as de...

Tip-loaded fast-dissolving microneedle patches for photodynamic therapy of subcutaneous tumor.

5-Aminolevulinic acid (ALA) based photodynamic therapy (PDT) is a modality for the treatment of cancers. However, due to its hydrophilicity and zwitterionic nature, the transdermal delivery of ALA is limited for the PDT of subcutaneous tumor. To address this problem, tip-loaded fast-dissolving microneedles made of sodium hyaluronate (HA) were fabricated by two casting method. 122 μg of ALA was loaded per microneedle patch and mainly distributed in the tips, which could improve the utilization of drug and...

Transdermal Cubic Phases of Metformin Hydrochloride: In Silico and In Vitro Studies of Delivery Mechanisms.

Transdermal delivery is one of important controlled drug release strategies for drug development. Cubic phases are the assemblies of amphiphilic molecules in water with the hydrophilic-hydrophobic interpenetrating network for transdermal delivery of both hydrophilic and hydrophobic drugs. However, many details about the transdermal delivery of cubic phases remain unclear. Here, metformin hydrochloride (Met) cubic phases were prepared with glyceryl monooleate (GMO), ethanol and water. The cubic structure was...

Binary Patch Assessment by Goldfish Under Safe and Dangerous Conditions.

Food resources can occur heterogeneously in space or time and differ in their abundances. A forager should be able to determine the value of a patch and choose optimally how to exploit it. However, patch choice and exploitation may be influenced by predation risk. Using the Giving up Densities (GUDs) technique, we evaluated goldfish patch assessment and choice in a binary patch choice experiment. We offered a pair of unequal food patches containing high and low food quantity. We quantified goldfish foraging...
