beta-1
First experimental release
Beta-1 is a technical designation in biology and pharmacology, most commonly referring to beta-1 adrenergic receptors—proteins found primarily in heart tissue that respond to adrenaline and noradrenaline.
Drugs called beta-1 blockers target these receptors to slow heart rate and lower blood pressure: The cardiologist prescribed a beta-1 selective blocker for his arrhythmia.
