Pharmacotherapy, or the use of drugs for treatment, is based on two concepts: pharmacokinetics and pharmacodynamics. Most simply put, pharmacokinetics (PK) is how the body affects the drug while pharmacodynamics (PD) is how the drug affects the body.
Please explain the pharmacokinetics and pharmacodynamics of either a stimulant, antidepressant, anti-psychotic, mood stabilizer or anti-anxiety medication.
