Catecholamines are the most commonly used 22 23 73 vasoactive agents in the intensive care unit, and among them norepinephrine is the first-line therapy in most 24 25 74 clinical conditions. Inotropes are indicated when myocardial function is depressed and dobutamine remains the 26 27 75 first-line therapy. Vasoactive drugs have a tight therapeutic margin and expose the patients to potentially lethal 28 29 76 complications. Thus, these agents require precise therapeutic targets, close monitoring with titration to the 30 31 77 minimum efficacious dose and should be weaned as promptly as possible. Moreover, the use of vasoactive drugs 32 33 78 in shock requires an individualized approach. Vasopressin and possibly angiotensin II may be useful owing to 34 35 79 their norepinephrine sparing effects. 36 37 80 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 4 63 64 65 81 Acute illnesses are often characterized by a loss in cardiovascular homeostasis. Underlying mechanisms may 1 2 82 include multiple factors altering blood volume (actual or effective), cardiac (diastolic and/or systolic) function or 3 4 83 the vessels (large vessels and/or microvasculature). Vasopressors and inotropes are vasoactive drugs that have 5 6 84 been developed to act on the vessels and the heart. In practice, a number of drugs are available with 7 8 85 heterogeneous mechanisms of action and varying benefit to risk balance. This narrative review provides a 9 10 86 summary of current knowledge about vasopressors and inotropes to guide intensive care physicians’ practices 11 12 87 when managing patients with shock. 13 14 15 88 Pharmacological basis 16 17 18 89 Catecholamines 19 20 90 Vasoactive agents are classified into sympathomimetics, vasopressin analogues, and angiotensin II. 21 22 91 Catecholamines are further subdivided in categories of indirect, mixed-acting, and direct acting. Only the direct 23 24 92 acting agents have a role in shock. Direct agents are further delineated by their selective nature (e.g. dobutamine, 25 26 phenylephrine) or non-selective activity (e.g. epinephrine, norepinephrine) on , , , , and receptors [1]. 27 93 a1 a2 b1 b2 b3 28 29 94 Catecholamines are most often linked to clinical improvement in shock states [1,2]. Catecholamines act by 30 31 95 stimulation of either a or b receptors, exerting excitatory action on smooth muscle and resulting in 32 33 96 vasoconstrictive or vasodilatory effects in skin, kidney, and lung. Intravenous (IV) administration of epinephrine 34 35 97 or norepinephrine results in increasing blood pressure with increasing dose. The rise in blood pressure is due to 36 37 98 vasoconstriction and b receptor stimulation. b-stimulation directly increases inotropy and heart rate. Although 38 39 99 receptor responses have classically been presented as linear, all responses follow a sigmoidal type curve 40 41 100 resulting in a pharmacological response to increasing doses followed by a plateau affect. Dopamine receptors 42 43 101 include at least five subtypes that are broadly distributed in the central nervous system, in pulmonary and 44 45 102 systemic blood vessels, cardiac tissues and the kidneys [1]. The impact on receptors provides the pharmacologic 46 47 103 basis for catecholamine therapy in shock. Clinicians should also be aware of their effects on glycogenolysis in 48 49 104 the liver and smooth muscle, free fatty acid release from adipose tissue, modulation of insulin release and 50 51 105 uptake, immune modulation, and psychomotor activity in the central nervous system. 52 53 106 54 55 107 56 57 108 58 59 109 Vasopressin and analogues 60 61 62 5 63 64 65 110 Vasopressin is a potent nonapeptide vasopressor hormone released by the posterior pituitary gland in response to 1 2 111 hypotension and hypernatremia [3].
