What is the primary function of a drug delivery system?

  1. To control the release of a drug

  2. To enhance drug absorption

  3. To target specific tissues or cells

  4. All of the above


Correct Option: D
Explanation:

Drug delivery systems aim to control drug release, enhance absorption, and target specific tissues or cells.

Which route of drug administration bypasses the gastrointestinal tract?

  1. Oral

  2. Intravenous

  3. Subcutaneous

  4. Rectal


Correct Option: B
Explanation:

Intravenous administration directly delivers drugs into the bloodstream, bypassing the gastrointestinal tract.

What is the primary factor affecting drug absorption through the skin?

  1. Molecular weight of the drug

  2. Lipid solubility of the drug

  3. pH of the skin

  4. All of the above


Correct Option: B
Explanation:

Lipid solubility is the primary factor influencing drug absorption through the skin.

Which drug delivery system is designed to release drugs over an extended period of time?

  1. Sustained-release tablet

  2. Transdermal patch

  3. Nasal spray

  4. Suppository


Correct Option: A
Explanation:

Sustained-release tablets are formulated to release drugs gradually over an extended period.

What is the primary advantage of using liposomes as a drug delivery system?

  1. Enhanced drug stability

  2. Targeted drug delivery

  3. Controlled drug release

  4. All of the above


Correct Option: D
Explanation:

Liposomes offer enhanced drug stability, targeted drug delivery, and controlled drug release.

Which type of drug formulation is commonly used for ophthalmic administration?

  1. Tablet

  2. Capsule

  3. Eye drops

  4. Injection


Correct Option: C
Explanation:

Eye drops are a common drug formulation for ophthalmic administration.

What is the primary mechanism of drug absorption through the lungs?

  1. Passive diffusion

  2. Active transport

  3. Facilitated diffusion

  4. Pinocytosis


Correct Option: A
Explanation:

Drug absorption through the lungs primarily occurs via passive diffusion.

Which type of drug formulation is commonly used for sustained release of drugs in the gastrointestinal tract?

  1. Enteric-coated tablet

  2. Sustained-release capsule

  3. Oral solution

  4. Suppository


Correct Option: B
Explanation:

Sustained-release capsules are commonly used for sustained drug release in the gastrointestinal tract.

What is the primary function of a controlled-release drug delivery system?

  1. To maintain a constant drug concentration in the body

  2. To reduce the frequency of drug administration

  3. To improve patient compliance

  4. All of the above


Correct Option: D
Explanation:

Controlled-release drug delivery systems aim to maintain a constant drug concentration, reduce administration frequency, and improve patient compliance.

Which drug delivery system is commonly used for targeted drug delivery to specific tissues or cells?

  1. Liposomes

  2. Nanoparticles

  3. Microspheres

  4. All of the above


Correct Option: D
Explanation:

Liposomes, nanoparticles, and microspheres are all commonly used for targeted drug delivery.

What is the primary advantage of using nanoparticles as a drug delivery system?

  1. Enhanced drug stability

  2. Targeted drug delivery

  3. Controlled drug release

  4. All of the above


Correct Option: D
Explanation:

Nanoparticles offer enhanced drug stability, targeted drug delivery, and controlled drug release.

Which type of drug formulation is commonly used for sublingual administration?

  1. Tablet

  2. Capsule

  3. Lozenge

  4. Injection


Correct Option: C
Explanation:

Lozenges are a common drug formulation for sublingual administration.

What is the primary factor affecting drug absorption through the gastrointestinal tract?

  1. Molecular weight of the drug

  2. Lipid solubility of the drug

  3. pH of the gastrointestinal tract

  4. All of the above


Correct Option: D
Explanation:

Molecular weight, lipid solubility, and pH of the gastrointestinal tract all influence drug absorption.

Which type of drug formulation is commonly used for rectal administration?

  1. Tablet

  2. Capsule

  3. Suppository
