Abstract:
Ethosomes, as a new vector for transdermal drug delivery, could obviously improve the transdermal penetration of drugs. In this study, we prepared testosterone undecanoate ethosomes, with TU ethosomes as the basic remedy, to determine its appearance, particle size, entrapment efficiency (EE) and membrane fluidity. Meanwhile, a transdermal test was conducted in mice, in order to determine the permeability characteristics of ethosomes as a vector for transdermal drug delivery, and compare transdermal behaviors of TU ethosomes, liposomes and their ethanol solutions.

Methods for Studying Drug Absorption: In vitro
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...
Methods for Studying Drug Absorption: In situ
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
