What Loniten is used for
Loniten lowers high blood pressure. High blood pressure is also called hypertension.
Loniten works by relaxing the muscles of your blood vessels. This makes it easier for your blood to flow around your body
and results in a decrease in your blood pressure.
Loniten is reserved for use in severe cases of high blood pressure where it is used in combination with other blood pressure
Your doctor may have prescribed Loniten for another purpose. Ask your doctor if you have any questions about why Loniten
has been prescribed for you.
This medicine is available only with a doctor's prescription.
