Partial agonists do not activate receptors with maximal efficacy, even with maximal binding, causing partial responses compared to those of full agonists (efficacy between 0 and 100%).
Agonistas parciais, que non activan os receptores coa eficacia máxima, incluso cando se produce unha unión máxima, e causan só respostas parciais comparadas coas dos agonistas completos (eficacia entre 0 e 100%).
