The situation is as follows: there is an off label use for quinidine that would require a 10 mg dose. However, the only format available is a 200 mg plastic depot tablet that is very difficult to crush homogeneously. I am not aware of the chemical form quinidine is in at these tablets, and therefore unsure if it would be possible to dissolve it into some liquid in order to divide it into 20 doses. I am also thinking of an ultrasound washer warmed up to around body temperature to help dissolving the quinidine from the depot tablet. Any insights into this?
