Pharmacokinetics
| Term | Definition |
|---|---|
| What are the 4 processes studied in pharmacokinetics? | (ADME)Absorption, Distribution, Metabolism, and Excretion |
| Absorption of a medication is dependent on which 2 processes? | -Disintegration: The breaking down of meds into smaller parts -Dissolution: Dissolving a solid med. into a liquid |
| What is a DISADVANTAGE of a sustained release product? | The preparation might now release enough medication to treat severe symptoms, such as breakthrough pain |
| Which 3 factors effect the distribution of a medication? | -Acid-Base Status -Solubility -Volume of distribution |
| What are 5 examples of medications that are weak bases? | -Morphine -Diphenhydramine -Diazepam -Amlodipine -Midazolam |
| Endings of med. names that indicate weak bases? | -acetate, -calcium, -decanoate, -disodium, -dinitrate, -furoate, -mononitrate, and -propionate |
| What type of molecule dissolves in water? | A charged molecule that is highly polar |
| Which conditions are treated by medications with a high volume of distribution? | Illnesses that originate in the brain |
| What is first-pass metabolism? | When a med. is first destroyed by the liver before it enters the excretory system |
| What is the primary organ of excretion for water soluble medications? | The kidneys |
