IV hydralazine

A cardiologist today told me that IV hydralazine is a drug which should never be used for anything. Reason is because it has an extremely short duration of action yet extremely rapid onset of action. It is apparently only good for making the numbers look better for your attending, but otherwise exceptionally worthless. If this is the case, why have I seen an order for "hydralazine IV 10mg IV PRN Psys >160" on so many patients with medicine consult for "hypertension."
