This study developed a method to evaluate Zhike Pingchuan sustained-release tablets. The results show well-balanced drug release over 10 hours, indicating improved performance.
Area of Science:
- Pharmacology
- Pharmaceutical Sciences
- Analytical Chemistry
Context:
- Zhike Pingchuan sustained-release tablets are a novel drug formulation.
- Evaluating the in vitro release profile is crucial for ensuring consistent drug delivery and therapeutic efficacy.
- Existing methods may not adequately capture the complex release kinetics of sustained-release formulations.
Purpose:
- To establish and validate a robust analytical method for assessing the in vitro release of Zhike Pingchuan sustained-release tablets.
- To determine the release behavior of key marker components (ephedrine, pseudoephedrine, scopolamine) over time.
- To confirm if the release profile is well-balanced and consistent with sustained-release characteristics.
Summary:
- A method utilizing specific chromatographic conditions was developed to quantify ephedrine, pseudoephedrine, and scopolamine release from Zhike Pingchuan sustained-release tablets.
- Dissolution curves of the three marker components were analyzed to assess the release behavior.
- The Zhike Pingchuan sustained-release tablets demonstrated a well-balanced release profile over a 10-hour period when compared to conventional tablets.
Impact:
- The established method provides a reliable tool for quality control and characterization of Zhike Pingchuan sustained-release tablets.
- This evaluation method can ensure consistent drug release, potentially leading to improved patient compliance and therapeutic outcomes.
- The findings support the suitability of the developed chromatographic conditions and marker components for routine in vitro release testing.

Theories of Dissolution: Diffusion Layer Model
This process starts with a thin layer, saturated with the drug, forming at the interface between the solid and liquid. The solute then diffuses from this layer into the main solution. The Noyes-Whitney equation suggests that the rate of dissolution relies on the diffusion...
