Morphology
calcium-channel + blocker
The compound clearly decomposes into calcium + channel + blocker, so its meaning — a substance that blocks calcium channels — is directly inferable from the constituent meanings. Although it's a technical medical term, the compositional pattern (what blocks what) is regular and cross-linguistically transparent, so a B1 learner who knows the parts can grasp that it denotes a drug that inhibits calcium movement through channels.
Etymology
Calcium-channel blocker imagines the medicine as a blocker that closes tiny channels or doors that let calcium into the cells of the heart and blood vessels. By closing those doors, it keeps calcium out so the heart and vessels relax, which 'lowers blood pressure' and eases chest pain.
