I came across an interesting little article on the pharmacist technique of compounding:
Compounding often is used to change the delivery method of a medication. For instance, if a patient has an allergic reaction from a shot or cannot swallow large pills, a compounding pharmacist can find an alternative approach, such as a cream or gel or a lollipop, to get a patient the proper dosage of medication.
This in turn led to a phrase that gave me quite a jolt of wishful thinking:
The patient was taking a high daily dosage of morphine but was still in pain. Chadwick suggested a ketamine nasal spray, which proved to be effective and considerably less expensive.
Mmm... ketamine nasal spray. Used effectively by pharmacists, it is an effective medicine. But if it falls into the wrong hands, you're looking at a whole host of ravers and clubbers collapsing in the streets.
