• Adrenaline — A hormone secreted by the adrenal medulla and a neurotransmitter released by the sympathetic nervous system during stress, fear, or intense physical effort; epinephrine. It acts rapidly on adrenergic receptors, causing an increased heart rate, peripheral vasoconstriction, dilation of the airways, and mobilization of glucose reserves, preparing the body for the 'fight or flight' response. Figuratively, it describes a state of intense excitement.
• Anaphylactic — Pertaining to anaphylaxis; triggering, accompanying, or characterizing an acute, systemic, and potentially lethal allergic reaction, structurally initiated by the massive and abrupt release of chemical mediators (such as histamine) from mast cells and basophils following an antigen-antibody immunological conflict. In a clinical sense, it defines severe manifestations characterized by a collapse in blood pressure and asphyxiation.
• Antiadrenergic — Blocking, inhibiting, or diminishing the effects of adrenaline and noradrenaline on adrenergic receptors within the sympathetic nervous system. In medical practice, it refers to a class of medications (sympatholytics), such as alpha-blockers and beta-blockers, used to treat hypertension and cardiac arrhythmias.
• Auto-injector — A pre-filled medical device equipped with an automated spring-loaded mechanism, designed to allow patients or untrained personnel to rapidly self-administer a precise, pre-measured dose of medication via intramuscular or subcutaneous injection. It is primarily utilized in critical emergencies, such as administering epinephrine for anaphylactic shock or antidotes following exposure to nerve agents.
