Morphology

proprietary + drug

This is a straightforward adjective + noun composition: 'proprietary' (owned/brand-protected) modifies 'drug', so the meaning 'a drug owned, marketed, or sold exclusively by a company' is directly predictable from the parts. The legal nuance about patents/trademarks is specialized but does not block comprehension for a learner who knows both constituent words.

Etymology

Proprietary drug comes from proprietary, meaning 'owned', and drug as a medicine. It refers to a medicine sold under one company's brand and protected by a patent. A patent is a legal right that stops other companies copying it, so the phrase means a medicine 'sold only by one company'.
