Positively inotropic agents increase the strength of muscular contraction
muscular contraction
Muscle contractions can be described based on two variables: length and tension. A muscle contraction is described as isometric if the muscle tension changes but the muscle length remains the same. In contrast, a muscle contraction is isotonic if muscle tension remains the same throughout the contraction.
. The term inotropic state is most commonly used in reference to various drugs that affect the strength of contraction of heart muscle (myocardial contractility). However, it can also refer to pathological conditions.
What are inotropes examples?
The most commonly used inotropes are the catecholamines; these can be endogenous (eg, adrenaline, noradrenaline)or synthetic (eg, dobutamine, isoprenaline). These medicines act on the sympathetic nervous system.
What is meant by ionotropic?
Inotropic: Affecting the force of muscle contraction. An inotropic heart drug is one that affects the force with which the heart muscle contracts. Ionotropic can be negative or positive.
