Morphology

blocker = block (semi-transparent) = block + er

The drug sense is still built from 'block' plus '-er', but the medical specialization makes the meaning somewhat less obvious for an average learner.

Etymology

Blocker comes from block ('a barrier or stop') and -er ('one who does something'). So a medical blocker is a drug that 'stops' a specific action in the body, for example beta blockers slow the heart rate.
