Transdermal (topical) drugs - ans ✔ - drugs placed on the skin (patch) allowing slow absorption over
time
Concentration gradient - ans ✔ - drugs moving from areas of higher concentration to lower
concentration
Bioavailability - ans ✔ - measures the amount of drug that gets absorbed and is available to patient
