the claim

Drugs sharing the exact same chemical formula always work identically in the human body

the verdict
REFUTED
the evidence says no
Recorded sources
0 sources for · 2 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that drugs sharing the exact same chemical formula always work identically in the human body?

No. Drugs with the exact same chemical formula do not always work identically in the human body, as stereoisomers and structural isomers can exhibit markedly different pharmacological properties, receptor binding, and biological effects.

The analysis

The claim is that drugs with the exact same chemical formula always work identically. The retrieved papers, specifically those discussing stereoisomers and optical isomers (like the comparison of isomeric nicotinic receptor agonists and dihydroquercetin stereoisomers), explicitly show that compounds with the same chemical formula can have very different biological activities, binding affinities, and pharmacological effects due to spatial arrangements. Thus, the claim is clearly refuted by scientific evidence.
