Primary Institution: Oregon State University
Hypothesis
The study aims to assess the penetration of hydrocortisone from various topical products through different membranes.
Conclusion
The hydrocortisone gel formulation showed significantly higher penetration rates compared to other topical products.
Supporting Evidence
- The gel formulation released the highest cumulative amount of hydrocortisone through synthetic membranes.
- Hydrocortisone diffusion through NHEK was 2.7 times greater from the gel formulation than other topical formulations.
- Pre-washing the skin significantly increased hydrocortisone diffusion rates.
Takeaway
This study looked at how well hydrocortisone cream can get through skin and other materials, finding that a gel version works best.
Methodology
The study used an Upright Franz Cell to measure hydrocortisone diffusion through synthetic membranes, mouse skin, and cultured human skin.
Limitations
The study had a small sample size, which may affect the reliability of the results.
