• This technique aims to improve the accuracy of pharmacokinetic assessments.

Purpose of Study

• To analyze the pharmacokinetic profile of a drug using a steady infusion method.
• To compare the efficacy of carotid artery infusion against other administration methods.
• To enhance the understanding of drug behavior in vivo.

Methods Used

• Custom catheter fabrication from polyethylene tubing.
• Securing the catheter within the mouse carotid artery.
• Connecting the mouse to an automated infusion pump.
• Infusing the drug at a steady rate and collecting blood samples.

Main Results

• Successful infusion of the drug through the carotid artery.
• Regular blood sample collection enabled pharmacokinetic analysis.
• Liquid chromatography and mass spectrometry used for concentration determination.
• Demonstrated advantages over traditional drug administration methods.

Conclusions

• The carotid artery infusion method is effective for pharmacokinetic studies.
