Pharmaceutically, a non-endogenous compound in the field of biological/organic chemistry. Essentially meaning, the unnatural occurence or man made molecule.
Oxymorphone is a semi synthetic compound derived from naturally occurring thebaine and morphine found within the opium poppy plant. Fentanyl, another opioid agonist is not derived from any endogenous compound; therefore it is considered a fully synthetic chemical.
