Pharmacy and Nursing Student Research and Evidence-Based Medicine Poster Session

Objective: To determine if andrographolide (AND) impacts the pharmacokinetics of carbamazepine (CBZ).

Background: CBZ is an anticonvulsant medication that is metabolized in the liver by cytochrome P450 (CYP) enzymes. AND is an over-the-counter medication that is common in Eastern cultures to treat inflammation and is a CYP enzyme inhibitor. Because CBZ is metabolized in the liver by these specific CYP enzymes, coadministration of andrographolide and CBZ could result in a herb-drug interaction.

Methods: Sprague-Dawley rats (N=12) aged between 3 months and 6 months (250-350 g) will be split into control (N=6) and treatment (N=6) groups. The treatment group will receive …

Central to the mechanism of how drugs work are the concepts of solubility and bioavailability. Drugs enter the body via absorption into the bloodstream, arrive at the target location, and bind to receptors to cause an effect. Drugs need to be soluble enough to pass through the cell membrane to enter and exit the bloodstream. Higher solubility generally correlates to higher bioavailability. Additionally, the smaller the particle size, the easier the drug will pass through the membrane into the blood plasma. Researchers have designed a system to categorize solubility class: Class I being high permeability and high solubility, Class II …
