Naltrexone is best known for helping treat drug and alcohol addiction. But, low-dose naltrexone treatment may also reduce lupus pain and inflammation.
Medications are designed to impact the body in a particular way, towards a particular goal. What they do in the body, the drug action, is known as pharmacodynamics. Generally speaking, there are 2 ways that a medication can cause a change. A medication can be an:
- Stimulate and activate receptors
- Antagonist (blockers)
- Stop agonists from activating receptors
Active receptors either trigger a particular response from the body or trigger the release of hormones (which in turn trigger the desired response). Receptors are located in the cell membrane or inside a given cell. The active ingredient in a medication attaches to the receptor using a specific type of chemical bond depending on the drug (covalent, ionic, hydrogen, hydrophobic).
