Study Notes
Passive Transfer of Drugs
- The passive transfer of a drug from a region of higher concentration to a region of lower concentration is influenced by concentration gradients.
Drug Absorption
- Solid dosage forms, such as tablets and capsules, have the greatest absorption when administered orally.
- Liquid dosage forms, such as solutions and suspensions, have the slowest absorption when administered orally.
Transport Mechanisms
- The sodium–potassium pump is an example of active transport, which involves the use of energy to move molecules against their concentration gradient.
Enteric Coatings
- Enteric coatings on drugs are used to resist the acidic environment of the stomach and release the drug in the intestine, where the pH is more neutral.
