Pharmacology and Therapeutics Questions

Multiple choice

Which of the following is an incretin mimetic commonly used to treat type 2 diabetes?

  1. Exenatide

  2. Metformin

  3. Insulin

  4. Glipizide
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Exenatide is an incretin mimetic that is commonly used to treat type 2 diabetes. It works by mimicking the effects of incretins, which are hormones that are released from the gut after a meal and stimulate the release of insulin from the pancreas. This leads to a decrease in blood glucose levels.

Multiple choice

Which of the following is a sodium-glucose cotransporter 2 (SGLT2) inhibitor commonly used to treat type 2 diabetes?

  1. Canagliflozin

  2. Metformin

  3. Insulin

  4. Glipizide
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Canagliflozin is a sodium-glucose cotransporter 2 (SGLT2) inhibitor that is commonly used to treat type 2 diabetes. It works by inhibiting the reabsorption of glucose in the kidneys, leading to an increase in the excretion of glucose in the urine and a decrease in blood glucose levels.

Multiple choice

Which of the following is a glucagon-like peptide-1 (GLP-1) receptor agonist commonly used to treat type 2 diabetes?

  1. Liraglutide

  2. Metformin

  3. Insulin

  4. Glipizide
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist that is commonly used to treat type 2 diabetes. It works by mimicking the effects of GLP-1, which is a hormone that is released from the gut after a meal and stimulates the release of insulin from the pancreas and inhibits the release of glucagon from the pancreas. This leads to a decrease in blood glucose levels.

Multiple choice

Which technology is commonly used for the analysis of drug metabolism and pharmacokinetics?

  1. Mass spectrometry

  2. Chromatography

  3. Electrophoresis

  4. Spectrophotometry
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mass spectrometry is widely used for the analysis of drug metabolism and pharmacokinetics, allowing researchers to study the absorption, distribution, metabolism, and excretion of drugs in the body.
