USP Dissolution Profile at Multiple pH Testing
The United States Pharmacopeia (USP) Dissolution Profile at Multiple pH testing is a critical procedure used in the pharmaceutical industry to ensure that drug products meet dissolution specifications across various simulated physiological conditions. This method provides insights into how the active pharmaceutical ingredient (API) and excipients behave under different gastrointestinal conditions, which are essential for assessing bioavailability.
The test involves subjecting a sample of the drug product to multiple pH solutions that mimic the acidic and alkaline environments encountered in the stomach and intestines. The dissolution rate is monitored over time, and the results are compared against USP Dissolution Profile specifications to ensure compliance with regulatory requirements.
Understanding the dissolution profile at different pH levels helps pharmaceutical manufacturers optimize drug formulations for better patient outcomes. It also aids in identifying potential issues such as poor disintegration or incomplete release of the active ingredient, which could lead to suboptimal therapeutic effects.
The USP 716 Dissolution Method specifies a series of tests that must be conducted at different pH levels (typically ranging from 1.2 to 7.0). This ensures that the drug product is stable and effective under various conditions, thereby enhancing patient safety and efficacy.
Our team specializes in conducting these tests using advanced equipment such as Dissolution Testing Systems (DTS) compliant with USP standards. These systems are capable of accurately measuring the amount of dissolved active ingredient over time, providing precise data that can be used for formulation optimization and quality control.
| pH Level | Simulated Body Part | Description |
|---|---|---|
| 1.2 | Stomach (Gastric Juice) | Most acidic environment; highest risk for API stability. |
| 4.0 | Duodenum (Initial Small Intestine) | Moderately acidic to neutral, where some drugs may begin to dissolve. |
| 6.8 | Terminal Ileum and Colon | Closest to physiological pH; least acidic condition tested. |
The dissolution profile is a key parameter in the development and quality assurance of pharmaceutical products. By conducting USP Dissolution Profile at Multiple pH Testing, we ensure that the drug product will perform consistently across different patients' gastrointestinal environments, thereby enhancing its therapeutic effectiveness.
