As with other transdermal methods, care must be taken to be sure there isn't any air bubbles trapped between the patch and the membrane. Transdermal dissolution methods tend to be finished at 32 degrees Celsius to imitate pores and skin temperature.
The apparatus is then operated at a set pace and temperature, ordinarily mimicking the conditions with the human digestive process. Above a set period, samples are taken in the test media and analyzed to measure the amount of drug dissolved at each sampling place.
There are several 'official' types of dissolution test apparatus, Each and every with critical options and benefits. They consist of:
