The evolution in drug delivery technology
Pills, capsules and tablets are not an efficient way for a patient to take medication. Only about 25% of the drug actually reaches the place it needs to be due to drug metabolism, food affect, first pass metabolism, enzymatic degradation, and other factors.
Patients, typically, want:
- a lower dosage of their medication,
- faster onset of action and
- less side-effects.
The evolution of drug delivery technology is to increase the bioavailability, or absorption, of the drug from 25% to as much as 95% through a simple spray into the mouth.
