The transdermal route is a convenient non-invasive way for drug delivery, however, the hydrophobic compact nature of stratum corneum (SC) forms an obstacle hindering the diffusion of drugs particularly hydrophilic ones. Hence, the purpose of this study was to develop novel soft nano-vesicles, entitled Flexosomes, amalgamating two penetration enhancers, ethanol and one edge activator (EA) from various types and different hydrophilic-lipophilic balances. The tailored vesicles were loaded with tropisetron hydrochloride (TRO), a potent highly-soluble anti-emetic, and compared with ethosomes...

BACKGROUND: High blood pressure is common in acute stroke and is a predictor of poor outcome; however, large trials of lowering blood pressure have given variable results, and the management of high blood pressure in ultra-acute stroke remains unclear. We investigated whether transdermal glyceryl trinitrate (GTN; also known as nitroglycerin), a nitric oxide donor, might improve outcome when administered very early after stroke onset. METHODS: We did a multicentre, paramedic-delivered, ambulance-based, prospective, randomised, sham-controlled, blinded-endpoint, phase 3 trial in adults with presumed stroke within 4 h of onset, face-arm-speech-time score of 2 or 3, and systolic blood pressure 120 mm Hg or higher...
