Morphology
beta-adrenergic + block + agent
The headword contains the transparent compound 'blocking agent' (an agent that blocks), so the general idea — a substance that blocks something — is derivable from the parts. However, 'beta-adrenergic' is a technical, domain-specific modifier whose precise meaning (relating to beta-adrenergic receptors/effects) is not predictable from everyday vocabulary at B1, so the full biomedical sense requires specialist knowledge. Because part of the phrase is compositional but the crucial modifier is technical, the expression is only partially transparent.
Etymology
Beta-adrenergic blocking agent is named for what it does: it blocks signals from the body's beta-adrenergic system that tell the heart to beat faster, so the heart beats more slowly and with less force. That's why these medicines are used to 'slow the heart' and help with high blood pressure or 'irregular heartbeats'.
