Abstract

Background: Chao Phya Abhaibhubejhr Hospital has developed a 1.0% w/w cannabidiol (CBD) cream formulation for use in patients with psoriasis and dermatitis. Therefore, developing an accurate and reliable analytical method for CBD quantification is essential for product quality control.

Objective: To develop and validate a quantitative analytical method for CBD in the 1.0% w/w CBD cream formulation using the high-performance liquid chromatography (HPLC) technique.

Methods: The CBD in the cream formulation was analyzed using HPLC. The analysis utilized a NexLeaf CBX for Potency (C18) column maintained at 35°C, with a detection wavelength of 220 nm. A gradient elution of 0.085% orthophosphoric acid in deionized water and 0.085% orthophosphoric acid in acetonitrile was used as the mobile phase, at a flow rate of 1.6 mL/min. System suitability, specificity, linearity, range, accuracy, and precision were evaluated to validate the analytical method in accordance with ICH Q2(R1) guidelines.

Results: The developed quantitative method demonstrated specificity in separating CBD without interference from the cream base. The method showed good linearity in the concentration range of 1–100 µg/mL (R² = 0.9999). The accuracy, reported as recovery percentage, ranged from 98.5% to 101.2%, and the precision, reported as the relative standard deviation (%RSD), was less than 1.0% for both intra-day and inter-day tests. When the validated method was applied to analyze two samples of the 1.0% CBD cream, the measured CBD concentrations were 1.1023% and 1.1918% w/w.

Conclusion: The developed HPLC method for the quantitative analysis of CBD in the 1.0% w/w cream formulation meets international standards for active pharmaceutical ingredient analysis in terms of accuracy, precision, and reliability. It is suitable for use in quality control of CBD cream products at the hospital level.
