Study Questions
Oral Administration
Which of the following factors can affect the absorption of orally administered drugs?
Explanation
Stomach pH, food in the stomach, and blood flow to the gastrointestinal tract can all affect the absorption of orally administered drugs. For example, some drugs require an acidic environment for optimal absorption and may be affected by changes in stomach pH.
Food in the stomach can delay gastric emptying and slow down drug absorption.
Blood flow to the gastrointestinal tract can affect drug absorption by altering the rate at which drugs are delivered to the absorption site.
a. Stomach pH alone can affect drug absorption, but it is not the only factor.
b. Food in the stomach alone can affect drug absorption, but it is not the only factor.
c. Blood flow to the gastrointestinal tract alone can affect drug absorption, but it is not the only factor.
Which of the following is a disadvantage of oral drug administration?
Explanation
Oral drug administration has a slower onset of action compared to other routes such as intravenous or intramuscular administration. This is because orally administered drugs must first pass through the gastrointestinal tract and be absorbed into the bloodstream before they can exert their effects.
a. Convenience and ease of use are advantages of oral drug administration, not disadvantages.
c. Being less expensive than other routes is an advantage of oral drug administration, not a disadvantage.
d. Being non-invasive is an advantage of oral drug administration, not a disadvantage.
Which of the following drugs should not be crushed before administration?
Explanation
Answer: A. Enteric-coated tablets
Rationale:
A) Enteric-coated tablets: Enteric-coated tablets should not be crushed as they are designed to dissolve in the intestines rather than the stomach. Crushing these tablets can destroy the coating, leading to stomach irritation or reducing the drug's effectiveness by releasing it prematurely.
B) Immediate-release tablets: Immediate-release tablets are generally safe to crush as they are designed to dissolve quickly and release their medication immediately. However, it is essential to confirm with each medication as some exceptions exist.
C) Chewable tablets: Chewable tablets are meant to be chewed for quicker absorption, especially for individuals with difficulty swallowing. Crushing is unnecessary and does not alter the intended function of these tablets.
D) Sublingual tablets: Sublingual tablets are designed for absorption under the tongue to bypass the digestive system and enter the bloodstream directly. Crushing sublingual tablets may impair their efficacy as the medication would not be absorbed as intended.
Which of the following is an advantage of oral drug administration?
Explanation

In pharmacology, the routes of drug administration refer to the different methods by which medications are delivered into the body. Each route has its own advantages and disadvantages, influencing factors such as the drug's characteristics, desired therapeutic effect, patient factors, and urgency of treatment. Understanding the various routes of drug administration is essential for healthcare professionals to ensure safe and effective medication delivery.
Oral Administration
-Oral administration is the most common and convenient route for drug delivery. Medications are ingested through the mouth and absorbed into the gastrointestinal tract.
-Oral administration is the most common and convenient route for drug delivery. Medications are ingested through the mouth and absorbed into the gastrointestinal tract. This route includes tablets, capsules, liquids, and powders.
-However, the absorption can be affected by factors such as gastric emptying time, pH levels, and first-pass metabolism by the liver.
Advantages of oral administration include:
- Ease of use and patient acceptance.
- Self-administration capability.
- Absorption over a prolonged period, allowing for sustained therapeutic effects.
- Cost-effectiveness and availability of a wide range of medications in oral form.
Disadvantages of oral administration include:

- Potential for drug interactions with food or other medications.
- Possible degradation of drugs by stomach acid.
- Limited absorption for poorly soluble drugs or those affected by digestive enzymes.
Sublingual and Buccal Administration
- Sublingual administration involves placing a drug under the tongue, allowing it to dissolve and be absorbed into the bloodstream through the rich supply of blood vessels in the sublingual mucosa.
- Buccal administration involves placing a drug between the cheek and gum.
-These routes offer rapid drug absorption and avoid first-pass metabolism, as the drug bypasses the digestive system. Common medications administered via sublingual or buccal routes include nitroglycerin and some oral contraceptives.
Advantages of these routes include:
- Rapid drug absorption through the rich supply of blood vessels in the sublingual and buccal mucosa.
- Avoidance of first-pass metabolism, as the drug bypasses the digestive system.
