Formoterol Fumarate 141-151 potassium calcium-activated channel subfamily M regulatory beta subunit 2 Homo sapiens 95-101 7648384-6 1995 SUMMARY: Preclinical studies have shown both salmeterol and formoterol to be potent and selective at beta 2-adrenoceptors but to have different mechanisms and durations of action. Formoterol Fumarate 60-70 potassium calcium-activated channel subfamily M regulatory beta subunit 2 Homo sapiens 101-107
