Which of the following is NOT a common route of drug administration?

  1. Oral

  2. Intravenous

  3. Intramuscular

  4. Transdermal


Correct Option: D
Explanation:

Transdermal drug administration involves the application of drugs to the skin for systemic absorption, while oral, intravenous, and intramuscular are all common routes of drug administration.

What is the primary advantage of intravenous drug administration?

  1. Rapid onset of action

  2. Sustained release of drug

  3. Targeted drug delivery

  4. Reduced side effects


Correct Option: A
Explanation:

Intravenous drug administration delivers the drug directly into the bloodstream, resulting in a rapid onset of action.

Which of the following dosage forms is commonly used for sustained-release drug delivery?

  1. Tablets

  2. Capsules

  3. Injections

  4. Transdermal patches


Correct Option: D
Explanation:

Transdermal patches are designed to deliver drugs through the skin over an extended period of time, providing sustained-release drug delivery.

What is the main advantage of using enteric-coated tablets?

  1. Improved drug absorption

  2. Reduced side effects

  3. Targeted drug delivery

  4. Protection of the drug from stomach acid


Correct Option: D
Explanation:

Enteric-coated tablets are designed to resist stomach acid, protecting the drug from degradation and ensuring its release in the small intestine.

Which of the following factors can affect drug absorption from the gastrointestinal tract?

  1. Food intake

  2. pH of the stomach

  3. Presence of bile salts

  4. All of the above


Correct Option: D
Explanation:

Drug absorption from the gastrointestinal tract can be influenced by various factors, including food intake, pH of the stomach, and the presence of bile salts.

What is the primary mechanism of drug distribution throughout the body?

  1. Diffusion

  2. Active transport

  3. Pinocytosis

  4. Filtration


Correct Option: A
Explanation:

Drug distribution throughout the body primarily occurs via diffusion, a passive process where drugs move from areas of high concentration to areas of low concentration.

Which of the following factors can affect drug distribution in the body?

  1. Protein binding

  2. Blood-brain barrier

  3. Tissue perfusion

  4. All of the above


Correct Option: D
Explanation:

Drug distribution in the body can be influenced by various factors, including protein binding, the blood-brain barrier, and tissue perfusion.

What is the primary route of elimination for most drugs?

  1. Renal excretion

  2. Hepatic metabolism

  3. Pulmonary excretion

  4. Biliary excretion


Correct Option: A
Explanation:

The primary route of elimination for most drugs is renal excretion, where drugs are filtered by the kidneys and excreted in urine.

Which of the following factors can affect drug elimination?

  1. Age

  2. Gender

  3. Liver function

  4. All of the above


Correct Option: D
Explanation:

Drug elimination can be influenced by various factors, including age, gender, and liver function.

What is the term used to describe the time it takes for the concentration of a drug in the body to decrease by half?

  1. Half-life

  2. Clearance

  3. Volume of distribution

  4. Bioavailability


Correct Option: A
Explanation:

Half-life refers to the time it takes for the concentration of a drug in the body to decrease by half.

Which of the following is NOT a common type of solid oral dosage form?

  1. Tablets

  2. Capsules

  3. Pills

  4. Suppositories


Correct Option: D
Explanation:

Suppositories are not a common type of solid oral dosage form, as they are typically administered rectally or vaginally.

What is the main advantage of using liquid dosage forms?

  1. Ease of administration

  2. Rapid onset of action

  3. Sustained release of drug

  4. Improved bioavailability


Correct Option: A
Explanation:

Liquid dosage forms are generally easier to administer, especially for patients who have difficulty swallowing solid dosage forms.

Which of the following dosage forms is commonly used for topical drug delivery?

  1. Ointments

  2. Creams

  3. Gels

  4. All of the above


Correct Option: D
Explanation:

Ointments, creams, and gels are all commonly used for topical drug delivery, as they can be applied directly to the skin.

What is the primary advantage of using parenteral dosage forms?

  1. Rapid onset of action

  2. Sustained release of drug

  3. Targeted drug delivery

  4. Improved bioavailability


Correct Option: A
Explanation:

Parenteral dosage forms, such as injections, provide a rapid onset of action as the drug is directly introduced into the bloodstream.

Which of the following factors can affect the bioavailability of a drug?

  1. Dosage form

  2. Route of administration

  3. First-pass metabolism

  4. All of the above


Correct Option: D
Explanation:

Bioavailability of a drug can be influenced by various factors, including dosage form, route of administration, and first-pass metabolism.
