Yes but how does that happen.
Evan Howard
depends on the drug, for example, the ester in aspirin is readily hydrolyzed
a lot of things eventually will be subjected to oxidation by reaction with atmospheric oxygen - it isn't necessarily fast but it happens

Wow nice going idiot.
Nobody asked for the biological half life.
It was asked how long a substance takes to degrade just sitting on it's own.
It's incredibly how stupid you are.
Carson Anderson
So it's only oxidation?
What if you kept the medicine in an oxygen free container?
Also wouldn't only the outer part of the pill degrade? How would oxygen penetrate further than that to degrade the entire pill?

what if they were in a vacuum?

come on friend, this used to be a nice board

>A biological half-life or elimination half-life is the time it takes for a substance (drug, radioactive nuclide, or other) to lose one-half of its pharmacologic, physiologic, or radiological activity.
learn to use google if you cant word your question properly

yet that wiki article and the one it links to ONLY explains about half life inside the body

thx

Keeping them in an inert atmosphere or vacuum would very likely extend the lifetime but there are other methods of degradation than oxidation.
As mentioned there is hydrolysis, there are also self-reactive molecules.
Oxgyen would also be able to slowly diffuse through the medication is it is typically a "loosely" (on the molecule scale) packed solid with nanoscopic gaps for small gas molecules to pass through,

Slow board. No reason to bump.

They don't actually expire, it's a conspiracy to force good goys to buy new medicine constantly.

Depends on a case to case basis, some ointments become thick and dry. Some substances react with air and some mixtures start to separate again over time.
The expiration date basically just means the manufactures guarantee that the drug stays in best condition and potency in that time frame.
Most of the time you can still use the medicine for years after expiration date. But if it is for a potentially lethal disease, you probably don't want to take chances.

Depends on the drug. For example, some drugs are very insoluble and so have been specially formulated to have almost no crystal form (amorphous solid) or to have an unusual crystal form. This is not a thermodynamically stable state and the drug can spontaneously revert to its more stable state, usually because of the presence of water in the atmosphere that is slowly absorbed by the tablet.
If the drug forms its favored crystal, which is thermodynamically favorable, then solubility can go down enormously and the drugs become nearly useless.
Older drugs are probably not made with this kind of tech so they'd expire (if they did expire) through other kinds of degradation.
