4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Cardiotonic Agents

Agents that have a strengthening effect on the heart or that can increase cardiac output. They may be CARDIAC GLYCOSIDES; SYMPATHOMIMETICS; or other drugs. They are used after MYOCARDIAL INFARCT; CARDIAC SURGICAL PROCEDURES; in SHOCK; or in congestive heart failure (HEART FAILURE). (See all compounds classified as Cardiotonic Agents.)


Phosphodiesterase 3 Inhibitors

Compounds that specifically inhibit PHOSPHODIESTERASE 3. (See all compounds classified as Phosphodiesterase 3 Inhibitors.)
