⩥ Inhalation Route. Answer: medications absorbed throught the nasal
passages, oral passage, or endotracheal or tracheostomy tubes
⩥ What are the indications for inhalation therapy?. Answer: Drugs used
to help treat asthma or COPD (albuterol, corticosteroids) and inhaled
anesthetics.
⩥ What is a major advantage of inhalation therapy?. Answer: It has a
large surface area (~100 square meters of alveolar epithelium).
⩥ Why is inhalation therapy beneficial in terms of metabolism?.
Answer: It avoids first-pass hepatic metabolism.
⩥ How do inhalation doses compare to oral doses?. Answer: Smaller
doses achieve equivalent effects to the oral route.
,⩥ What is a disadvantage of inhalation therapy related to technique?.
Answer: It requires good technique and proper lung strength.
⩥ What is a challenge posed by the lungs in inhalation therapy?.
Answer: Must overcome the aerodynamic filter of the lungs.
⩥ What is a disadvantage of inhalation therapy regarding drug
deposition?. Answer: Only 10-40% of the drug is actually deposited in
the lungs from conventional devices.
⩥ What is a disadvantage of inhalation therapy related to mucus?.
Answer: Clearance by airway mucus.
⩥ What is the intrathecal/intraventricular route used for?. Answer:
Direct CNS drug delivery when blood-brain barrier limits systemic
administration
⩥ What is an advantage of the intrathecal/intraventricular route?.
Answer: Direct access to the central nervous system
⩥ How does the intrathecal/intraventricular route affect drug dosage?.
Answer: Lower doses are required for CNS effects
⩥ What is a disadvantage of the intrathecal/intraventricular route?.
Answer: It is a high-risk procedure requiring specialized skills
,⩥ What are potential serious complications of the
intrathecal/intraventricular route?. Answer: Infection, bleeding, nerve
damage
⩥ What is a limitation of the intrathecal/intraventricular route?. Answer:
Requires surgical implantation of delivery systems
⩥ Where is the intrathecal/intraventricular route limited to?. Answer:
Specialized centers and specific conditions
⩥ How does blood flow and perfusion affect absorption. Answer: Higher
blood flow and better perfusion to the site enhance drug absorption
⩥ How does blood flow at the absorption site affect drug pickup?.
Answer: Blood flow at the absorption site directly affects drug pickup
and transport to systemic circulation.
⩥ What is the relationship between blood flow and drug pickup speed?.
Answer: More blood flow results in faster drug pickup from the
absorption site.
⩥ Why is adequate blood flow important for drug absorption?. Answer:
Adequate blood flow ensures efficient drug removal from the absorption
site.
, ⩥ What happens to drug absorption with compromised blood flow?.
Answer: Compromised blood flow results in reduced drug absorption
and decreased bioavailability.
⩥ How does food interact with drugs?. Answer: Food can slow gastric
emptying
Fatty meals may enhance absorption
⩥ How can food act like a drug interaction?. Answer: Food can change
absorption, metabolism, or elimination.
⩥ How do fatty foods affect drug absorption?. Answer: Fatty foods
increase absorption; for example, Albendazole works better with fat.
⩥ How does protein affect drug absorption?. Answer: Protein decreases
absorption; for example, Levodopa competes with dietary protein.
⩥ What effect does dairy have on drug absorption?. Answer: Dairy
blocks absorption; for example, Tetracycline binds to calcium.
⩥ How does grapefruit juice affect drug metabolism?. Answer:
Grapefruit juice blocks enzymes, increasing many drug levels
dangerously.
