Affecting the force or energy of muscular contractions.
A substance that affects the contraction of muscles.
Affecting the way muscles contract, especially those of the heart.
Influencing the force of contraction of a muscle. Positive inotropic agents, such as digitalis drugs, improve contraction of the heart muscle. Disease states, such as congestive heart failure, lead to a decreased inotropic state of the heart causing impairment of effective muscle contraction.
Affecting the contraction of heart muscle. Drugs such as digitalis have positive inotropic action, stimulating heart muscle contractions and causing the heart rate to increase. Beta-blocker drugs, such as propranolol, have negative inotropic action, reducing heart muscle contractions and causing the heart rate to decrease.
Adjective describing anything that affects the force of muscle contraction. It is usually applied to the heart muscle; an inotrope such as digoxin is a drug that improves its contraction. Beta-blocker drugs such as propranolol have negative inotropic properties.
Influencing the force of muscular contractility.
The term is utilized to describe anything that influences the strength or energy of muscular contractions, either in a positive manner by enhancing the contractions or in a negative manner by weakening them.
Inotropic drugs refer to medications that stimulate and boost the strength of heart muscle contractions. These drugs are occasionally required immediately after a heart attack (myocardial infarction) to sustain blood pressure and tissue circulation. In such instances, drugs like dopamine and dobutamine are administered through intravenous infusion. In cases of chronic heart failure, digitalis drugs, particularly digoxin, may be employed for the same purpose of enhancing heart contractions.
