Medrogestone: analysis in serum by high-pressure liquid chromatography

Area of Science:

• Analytical Chemistry
• Pharmacology

Background:

• Medrogestone is a synthetic steroid with potential therapeutic applications.
• Accurate quantification of medrogestone in biological matrices is crucial for pharmacokinetic and pharmacodynamic studies.

Purpose of the Study:

• To develop and validate a specific and sensitive method for determining medrogestone concentrations in human and dog serum.

Main Methods:

• High-pressure liquid chromatography (HPLC) coupled with UV detection was employed.
• Selective removal of interfering substances was achieved through reaction with oxalyl chloride followed by an alkaline borate wash.

Main Results:

• The developed method demonstrated high specificity for medrogestone.
• A limit of detection of 2 ng/ml was achieved using a 5 ml serum sample.

Conclusions:

• This HPLC-UV method provides a reliable and sensitive approach for medrogestone determination in serum.
• The method's specificity and sensitivity make it suitable for clinical and research applications.
