Mycophenolate mofetil (CellCept, Myfortic) View full drug information Mycophenolate mofetil inhibits inosine monophosphate dehydrogenase (IMPDH) and suppresses de novo purine synthesis by lymphocytes, thus inhibiting their proliferation. It inhibits antibody production. Azathioprine (Imuran, Azasan) View full drug information Azathioprine antagonizes purine metabolism and inhibits synthesis of DNA, RNA, and proteins. It may decrease proliferation of immune cells, which results in lower autoimmune activity. Antimetabolites are used to block the uptake of vital nutrients needed by the cells. As implied, these drugs affect not only the cells of the immune system but also other cells of the body. The potency of therapy is dose dependent. Azathioprine is not effective treatment for acute rejection episodes but remains an economical choice for long-term immunosuppression. Sirolimus (Rapamune) View full drug information Sirolimus, also known as rapamycin, is a macrocyclic lactone produced by Streptomyces hygroscopicus. It is a potent immunosuppressant that inhibits T-cell activation and proliferation by a mechanism that is distinct from those of all other immunosuppressants. This inhibition suppresses cytokine-driven T-cell proliferation by inhibiting progression from the G1 phase to the S phase in the cell cycle. Inotropic Agents Class Summary After the procedure, the patient is maintained on a combination of pressor agents while the donor heart regains energy stores. Once stabilized, the patient is rapidly weaned from the ventilator and the pressors. The chosen combination depends on the training and experience of the center. Dopamine View full drug information Dopamine is a naturally occurring endogenous catecholamine that stimulates beta1-and alpha1-adrenergic and dopaminergic receptors in a dose-dependent fashion. It stimulates the release of norepinephrine. In low doses (2-5 μg/kg/min), dopamine acts on dopaminergic receptors in renal and splanchnic vascular beds, causing vasodilatation in these beds. In midrange doses (5-15 μg/kg/min), it acts on beta-adrenergic receptors to increase heart rate and contractility. In high doses (15-20 μg/kg/min), it acts on alpha- adrenergic receptors to increase systemic vascular resistance and raise blood pressure. Dobutamine View full drug information Dobutamine is a sympathomimetic amine with stronger beta than alpha effects. It increases the inotropic state. Vasopressors augment the coronary and cerebral blood flow during the low-flow state associated with severe hypotension. Dopamine and dobutamine are the drugs of choice to improve cardiac contractility, with dopamine the preferred agent in hypotensive patients. Higher dosages may cause an increase in heart rate, exacerbating myocardial ischemia.
