Norepinephrine (l-arterenol/Levarterenol or l-norepinephrine) is a sympathomimetic catecholamine with multiple roles including as a hormone and a neurotransmitter. As a stress hormone, norepinephrine affects parts of the brain where attention and responding actions are controlled. Along with epinephrine, norepinephrine also underlies the fight-or-flight response, directly increasing heart rate, triggering the release of glucose from energy stores, and increasing blood flow to skeletal muscle. Norepinephrine can also suppress neuroinflammation when released diffusely in the brain from the locus ceruleus. Norepinephrine may be used for blood pressure control in certain acute hypotensive states (e.g., pheochromocytomectomy, sympathectomy, poliomyelitis, spinal anesthesia, myocardial infarction, septicemia, blood transfusion, and drug reactions) and as an adjunct in the treatment of cardiac arrest and profound hypotension. Norepinephrine performs its action by being released into the synaptic cleft, where it acts on adrenergic receptors, followed by the signal termination, either by degradation of norepinephrine, or by uptake by surrounding cells. Prolonged administration of any potent vasopressor may result in plasma volume depletion which should be continuously corrected by appropriate fluid and electrolyte replacement therapy.If plasma volumes are not corrected, hypotension may recur when Norepinephrine is discontinued, or blood pressure may be maintained at the risk of severe peripheral and visceral vasoconstriction (e.g., decreased renal perfusion)with diminution in blood flow and tissue perfusion with subsequent tissue hypoxia and lactic acidosis and possible ischemic injury. Gangrene of extremities has been rarely reported. Overdoses or conventional doses in hypersensitive persons (e.g., hyperthyroid patients) cause severe hypertension with violent headache, photophobia, stabbing retrosternal pain, pallor, intense sweating, and vomiting.

Isoproterenol (trade names Medihaler-Iso and Isuprel) is a medication used for the treatment of bradycardia (slow heart rate), heart block, and rarely for asthma. Isoproterenol is a non-selective β adrenoreceptor agonist and TAAR1 agonist that is the isopropylaminomethyl analog of epinephrine. Isoprenaline's effects on the cardiovascular system (non-selective) relate to its actions on cardiac β1 receptors and β2 receptors on smooth muscle within the tunica media of arterioles. Isoprenaline has positive inotropic and chronotropic effects on the heart. β2 adrenoceptor stimulation in arteriolar smooth muscle induces vasodilation. Its inotropic and chronotropic effects elevate systolic blood pressure, while its vasodilatory effects tend to lower diastolic blood pressure. The overall effect is to decrease mean arterial pressure due to the β2 receptors' vasodilation. The adverse effects of isoprenaline are also related to the drug's cardiovascular effects. Isoprenaline can produce tachycardia (an elevated heart rate), which predisposes patients to cardiac arrhythmias.

Diammonium carbonate is a salt with the chemical formula (NH4)2CO3. Since it readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling salt. Ammonium carbonate may be used as a leavening agent in traditional recipes, particularly those from northern Europe and Scandinavia (e.g. Speculoos, Tunnbröd or Lebkuchen). It also serves as an acidity regulator and has the E number E503. Ammonium carbonate is the main component of smelling salts, although the commercial scale of their production is small. Buckley's cough syrup from Canada today uses ammonium carbonate as an active ingredient intended to help relieve symptoms of bronchitis. Ammonium carbonate is also used as an emetic.

2-Iminobiotin (2-IB) is a cyclic guanidino analog of biotin (Vitamin B7) and combined neuronal and inducible (but not endothelial) nitric oxide synthase inhibitor that has been demonstrated to improve neuroprotection in animal models of hypoxic-ischemic Brain Injury. While the exact mechanism of action has yet to be defined, 2-Iminobiotin potentially protects against hypoxic-ischemic brain damage by preventing nitric oxide or peroxynitrite-induced mitochondrial damage. In preclinical models, 2-Iminobiotin provides gender-specific neuroprotection against hypoxia-ischemia in neonatal rats by a NO-independent mechanism.

Dihydrocapsaicin is a capsaicinoid and analog and congener of capsaicin in chili peppers. Like capsaicin, it contributes to the spicy taste of chili peppers, although it is less potent than capsacian. Dihydrocapsaicin has been shown to induce hypothermia in rats, a property which may help protect victims of stroke and cardiac arrest.
