Purpose of the Study:
- To investigate the pharmacokinetic characteristics of Sinomenine when delivered via a transdermal patch.
- To establish a reliable analytical method for quantifying Sinomenine in plasma.
- To determine key pharmacokinetic parameters for Sinomenine transdermal delivery.
Main Methods:
- Plasma drug concentrations were measured in Beagle dogs using High-Performance Liquid Chromatography with Ultraviolet Detection (HPLC-UVD).
- Pharmacokinetic parameters were calculated using the Kinetica software package.
- An exclusive analysis method was developed and validated.
Main Results:
- The established analysis method demonstrated reliability.
- Key pharmacokinetic parameters included a Tmax of 8 hours, Cmax of 366 ng/mL, and MRT of 13 hours.

01:09Methods for Studying Drug Absorption: In situ
In situ experiments, such as the Doluisio method and Single-Pass Perfusion technique, provide critical insights into drug uptake by simulating in vivo conditions for drug absorption.
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,...

01:13Local Anesthetics: Pharmacokinetics
The potency and duration of action of local anesthetics (LAs) are determined by their pharmacokinetics. Pharmacokinetics describes how LAs are absorbed, distributed, metabolized, and eliminated from the body. When administered to the vascular tissues, LAs are quickly absorbed and enter the systemic circulation, reducing their localized effects. Adding vasoconstrictors such as epinephrine to LAs reduces their absorption into the systemic circulation, making them clinically effective. The...
