| Q. |
What are the characteristics of the mixed monolithic-reservoir devices? |
| A. | the drug has a large therapeutic index |
| B. | drug permeation rate is high |
| C. | the drug-polymer matrix is layered by rate- controlling membrane |
| D. | administration of emulsions |
| Answer» C. the drug-polymer matrix is layered by rate- controlling membrane | |
| Explanation: this device has drug release kinetics intermediate between monolithic and reservoir systems. here the drug-polymer matrix is layered by a rate controlling membrane. the release is controlled initially by the membrane but as the drug gets depleted the rate is controlled by diffusion of the drug. | |
