### General Pharmacology
1. **Question:** What is the definition of pharmacokinetics?
- **Answer:** Pharmacokinetics is the study of how a drug is absorbed,
distributed, metabolized, and excreted in the body.
2. **Question:** What is the therapeutic index?
- **Answer:** The therapeutic index is the ratio between the toxic dose
and the therapeutic dose of a drug, indicating its safety margin.
3. **Question:** What does the term “bioavailability” mean?
- **Answer:** Bioavailability is the proportion of a drug that enters the
circulation when introduced into the body and is able to have an active
effect.
4. **Question:** Which organ is primarily responsible for drug metabolism?
- **Answer:** The liver is the primary organ responsible for drug
metabolism.
5. **Question:** What is the primary route of drug excretion?
- **Answer:** The primary route of drug excretion is through the kidneys
via urine.
### Autonomic Nervous System Drugs
, 6. **Question:** What class of drugs is used to treat hypertension by
blocking beta-adrenergic receptors?
- **Answer:** Beta-blockers are used to treat hypertension by blocking
beta-adrenergic receptors.
7. **Question:** Name a common side effect of anticholinergic drugs.
- **Answer:** A common side effect of anticholinergic drugs is dry mouth.
8. **Question:** What is the mechanism of action of alpha-1 adrenergic
antagonists?
- **Answer:** Alpha-1 adrenergic antagonists work by blocking alpha-1
receptors, leading to vasodilation and decreased blood pressure.
9. **Question:** Which neurotransmitter is primarily affected by
benzodiazepines?
- **Answer:** Benzodiazepines primarily affect the neurotransmitter
gamma-aminobutyric acid (GABA).
10. **Question:** What is the primary therapeutic use of selective serotonin
reuptake inhibitors (SSRIs)?

disorders.
### Cardiovascular Drugs
11. **Question:** What is the mechanism of action of ACE inhibitors?
- **Answer:** ACE inhibitors block the conversion of angiotensin I to
angiotensin II, leading to vasodilation and reduced blood pressure.
12. **Question:** Name a commonly used diuretic for treating hypertension.
- **Answer:** Hydrochlorothiazide is a commonly used diuretic for
treating hypertension.
13. **Question:** What is the primary action of calcium channel blockers?
