In clinical researches performed to investigate the activity between beta adrenergic agonists as tocolytic agents, it was found that IP is more active compared to ritodrine and isoproterenol.11 However, its lack of activity towards specific b2-receptors causes major side effects characterised by tachycardia and hypotension in human obstetrics.
Hypokalemia can result from decreased intake (rare), translocation into cells (insulin, beta adrenergic agonists), or gastrointestinal/urine losses (diarrhea/aldosterone) (1).
The [alpha]-2 adrenergic agonists are the most commonly used in the equine practice, having important dose-dependent effect when higher doses or longer therapeutic times are applied, generating an important hypotensor effect (Muir WW et al., 2009), which is compensated with peripheral vaso-constriction, that, in the case of being prolonged, can affect retinal vessels, causing a pressure increasing and a tissue oxygen input reduction leading to a corioretinopathy and/or optic neuritis.
