Indirect response models have been successfully applied for a number of drugs that display a relatively slow onset of effect compared to their distribution to the site of action. Examples are corticosteroids, warfarin, furosemide and terbutalin. Such models are also particularly appropriate if the measured response is a change in circulating blood cells or endogenous proteins (e.g. hormones or cytokines).

Beta agonists (e.g. fenoterol, salbutamol (albuterol), terbutaline) can cause hypokalaemia. This can be increased by other potassium-depleting drugs such as the corticosteroids, diuretics (e.g. bendroflumethiazide, furosemide) and theophylline. The risk of serious cardiac arrhythmias in asthmatic patients may be increased. 

The serum potassium level of 15 healthy subjects was measured after they were given inhaled terbutaline 5 mg with either a placebo, furosemide 40 mg daily, or furosemide 40 mg with triamterene 50 mg daily for 4 days. With terbutaline alone the potassium levels fell by 0.53 mmol/L after taking furosemide as well they fell by 0.75 mmol/L and after furosemide and triamterene they fell by 0.59 mmol/L. These falls were reflected in some ECG (T wave) changes. ...
