Epinephrine
Epinephrine Mechanism of Action Epinephrine is a non‑selective adrenergic agonist that stimulates α‑ and β‑adrenergic receptors via the G‑protein–mediated cascade. α‑1 adrenoceptor activation → vascular smooth‑muscle contraction → ↑ systemic…
Epidiolex
Epidiolex Mechanism of Action Epidiolex is a purified, purified‑quality cannabidiol (CBD) formulation. Its antiepileptic effects are mediated through a multifaceted, low‑potency interaction with the endocannabinoid system and several non‑cannabinoid targets:…
Enzalutamide
Enzalutamide Mechanism of Action Enzalutamide is a second‑generation, non‑steroidal antagonist that binds with high affinity to the ligand‑binding domain of the androgen receptor (AR). It blocks AR nuclear translocation, DNA…
