Dissolving Microneedles Integrated With Liquid Crystals Facilitate Transdermal Delivery of Sinomenine Hydrochloride.

abstract：:A stability-indicating high-performance liquid chromatographic assay has been used to investigate the stability of solutions of melphalan under conditions that pertain to setting up in vitro chemosensitivity assays. Melphalan (1 and 20 micrograms/mL) was found to be 30% more stable in 150 mM NaCl solution (normal sali...
