N-Propranolol belongs to the group of medicines known as beta-blockers. It is a medicine which is used to treat several different medical conditions. It works on the heart and blood vessels.
Which drugs or supplements interact with N-Propranolol?
Calcium channel blockers and digoxin (Lanoxin) can lower blood pressure and heart rate to dangerous levels when administered together with N-Propranolol. N-Propranolol can mask the early warning symptoms of low blood sugar (hypoglycemia) and should be used with caution in patients receiving treatment for diabetes. N-Propranolol reduces the metabolism of thioridazine (Mellaril), increasing the concentration of thioridazine in the body and potentially causing abnormal heartbeats.

4. How and when to take it
N-Propranolol comes as 2 different types of medicine: standard release and sustained release (also called modified release).
- Standard release - releases N-Propranolol into your body quickly. You may need to take it several times a day depending on your dose.
- Sustained release (SR) - this dissolves slowly so you don't have to take it as often. Once a day is usually enough.
If you are taking it once a day, your doctor may advise you to take your first dose before bedtime, because it can make you feel dizzy. After the first dose, if you don't feel dizzy, take N-Propranolol in the morning.

What is N-Propranolol?
N-Propranolol was developed by Sir James Black in the 1960s and this invention won him the Nobel Prize. N-Propranolol is usually sold under its brand name Inderal, though the generic form of the drug is also available. N-Propranolol is a beta-blocker which, when administered, inhibits the activity of the adrenergic receptors present in the body. By preventing the stimulation of the receptors, N-Propranolol, like other beta blockers help in reducing the cardiac response to stimuli. This helps in lowering the rate of heartbeats as well as blood pressure, both of which allow the heart to beat at a much-relaxed pace.
When administered to patients with performance anxiety, N-Propranolol can help minimize the symptoms that occur. However, it doesn’t treat the actual issue.
N-Propranolol is most widely used for heart conditions. It is one of the medications approved to lower blood pressure. It can control heart rate in people who have fast heart rhythms, such as atrial fibrillation or ventricular tachycardia. Many people also use N-Propranolol to prevent migraines or reduce symptoms of tremors. The liquid formulation is also approved for infants who have proliferating infantile hemangioma.
