Do we know how a drug (medicine) works?
So for example, if you nick tylenol the effect is that your headache is gone, but what is the drug doing to your body/cells that is helping you?
I guess my point is if we know how the tablets works rather than a short time ago the effects we could create better drugs or take different approaches to make well people.
Answers:
Yes, researchers know how they work, contained by detail. Most of the newer drugs are designed at the molecular level to accomplish specific functions. Prozac is a perfect example. It be the first of what has become an entire class of drugs prearranged as SSRIs, or Selective Serotonin Re-uptake Inhibitors. Prozac is used to treat Depression. by design, it increases the amount of available Serotonin, (a neurotransmitter) in the synapses of the brain, by slowing the rate at which the cell that excrete the serotonin can reabsorb it.
The man who led the design troop has said that he did it purely to prove he could.

We know how plentiful drugs work. Researchers study the effects on a cellular level. That is how investigational drugs are created.
For example, NSAIDS like ibuprofen work by inhibition of prostaglandin synthesis by interrupting the cyclooxygenase pathway.
If you want to know more, study biochemistry and pharmacology.
thats pretty muich how it works today, but it's still got problems. These drugs do own bad side effects, but it's in acceptable margins, so they bring back approved by the FDA. Some do get recall if really bad things surface.
