What are the five factors that influence absorption? - (ANSWER)Gastric emptying
Time of contact with intestinal wall
Bowel perfusion
Food
Formation of non-absorbable complexes
Explain the hepatic first pass. - (ANSWER)Part of the drug is metabolized by the liver before it
reaches the blood.
Explain bioavailability. - (ANSWER)Percentage of administered drug that reaches systemic
circulation.
Name the 3 highly water-soluble drugs. - (ANSWER)Lithium, Amisulpride, Paliperidone
What are the 7 inhibitors of CYP? - (ANSWER)Paroxetine, Fluoxetine, Fluvoxamine,
Fluconazole, Ciprofloxacin, Ritonavir, Grapefruit juice
What are the 6 inducers of CYP? - (ANSWER)Carbamazepine, Phenytoin, Phenobarbital,
Primidone, smoking, St-John's Wort
What are the 6 factors that influence pharmacokinetics? - (ANSWER)Age, pregnancy, obesity,
sexe, comorbidities, genetics
Explain the half-life. - (ANSWER)The time it takes for the concentration of a drug to be reduced
by 50%
What are the 11 indications for TDM. - (ANSWER)Non-compliance/toxicity
, Lack of efficacy/adverse effects at normal dose
Relapse in maintenance treatment
Change in drug formulation
Pregnancy
Age
Comorbidities
Drug interactions
Change in BMI

What are the 4 factors influencing receptor binding? - (ANSWER)Affinity
Specificity
Saturability
Reversibility
Define intrinsic activity. - (ANSWER)The ability of a drug to initiate a response after binding to
a receptor
Define complete agonist vs. partial agonist. - (ANSWER)Decreased intrinsic activity, decreased
pharmacological effect, good affinity with receptor
Define competitive antagonist vs. non-competitive antagonist. - (ANSWER)Differences in dose
response curves
Increasing dose of agonist will change the response of a competitive antagonist.

receptor, ion channels, enzymes
