Prescribing inotropes in heart failure

Hello everyone,   I am on my cardiology rotation and am having trouble coming to grips to prescribing inotropes.  Can someone help me with the following:   1. Dobutamine - What is meant by singe, double triple strength  e.g. consultant asks to prescribe single strength dobutamine, is this 5mcg/kg/hr? and is double strength 10mcg/kg/hr? - How do you calculate the rate e.g. mg/hr, mg/min   2. Dopamine - What is meant by singe, double triple strength  e.g. consultant asks to prescribe single strength dobutamine, is this 5mcg/kg/hr? and is double strength 10mcg/kg/hr? - How do you calculate the rate e.g. mg/hr, mg/min   Ive been looking online for a 'dummies' guide to this like in the form of weight of patient, conentration to give and rate to run but am unable to find one - if you know of any good one please let me know.   Thanks.
