In heart failure, the dilation of blood vessels means that the work of the heart is facilitated and the pumping capacity of the heart increases.

Hydralazine contained in Apresolin may also be approved for the treatment of other conditions not mentioned in this leaflet. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.
