Mean values from 6 women Conclusion. The CDs have many attractive properties which make them unique as pharmaceutical excipients.

Similar results have been obtained for rabbit eye cornea (27) and nasal mucosa (14). The experimental results are in agreement with theory were the predicted increase is due to increase in the aqueous diffusion rate and the decrease, when excess CD is added, is due to decreasing partition coefficient. Cellophane membrane can be used to optimize the release from topical formulations (Figure 8). In this case Equation 3 can also be fitted to the relationship between flux and CD concentration. Penetration enhancers are frequently used in dermal and other topical formulations.

In this case Equation 3 can also be fitted to the relationship between flux and CD concentration. Penetration enhancers are frequently used in dermal and other topical formulations. Dermal penetration enhancers will affect the barrier function in the stratum corneum (28, 29). According to Equation 3 a co-operative effect between penetration enhancers and CDs should be expected and this has been demonstrated by experiment (30). ; ACS Symposium Series; American Chemical Society: Washington, DC, 1999.
