Pharmacology is the study of how drugs interact with the body and how the body affects the drugs. This includes understanding the drug's mechanism of action, absorption, distribution, metabolism, and excretion.
Pharmacology helps healthcare providers understand which medications are most effective for certain conditions.
By understanding a drug's pharmacokinetics and pharmacodynamics, nurses can properly assess medication impacts on patients' health and modify treatment plans accordingly.
When considering medications like sertraline (Zoloft) and cimetidine (Tagamet), it's crucial to understand how they affect each other. Sertraline is an antidepressant classified as a selective serotonin reuptake inhibitor (SSRI), while cimetidine is used to reduce stomach acid.
- Sertraline: It increases serotonin levels in the brain, improving mood and alleviating symptoms of depression.
- Cimetidine: It reduces acid production in the stomach, often used in treating ulcers and gastroesophageal reflux disease (GERD).
Understanding pharmacology allows healthcare providers to safely administer medications and anticipate possible side effects or interactions.
