Inderal is a prescription drug referred to as a beta blocker. It is used to treat certain heart and circulatory conditions. It is also effective against migraine headaches. Propranolol is the generic name of this drug and is generally cheaper. Inderal comes in various forms; extended-release capsules, oral tablets and liquid suspensions. Propranolol hydrochloride is the active ingredient in inderal for priority health. Lactose, magnesium stearate, maize starch, and hypromellose (E464) are other ingredients contained in the drug.
As a beta-blocker, inderal effects the flow of blood through arteries and veins. It is used to;
- Control symptoms of overactive thyroid gland like sharp breaths
- Reduce migraine headaches
- Calm abnormal anxiety
- Prevent stomach bleeding in patients who have swollen blood vessels in their gullet or those with increased blood pressure in their liver
- Control irregular heartbeat
- Prevent heart attack in patients with heart problem
- Treat tremors, enlarged muscles of the heart and high blood pressure
- Treat chest pains caused by blocked arteries
- Treat high blood pressure caused by an abnormal growth near the kidney
- Treat haemangiomas in infants above 5 weeks.
Inderal mode of operation is not fully known. Scientists believe that it acts on these health problems by blocking renin from the kidneys therefore decreasing the pressure on the heart. This will make heartbeat more consistent. Inderal is a non-selective blocker, therefore it performs similar functions on the lungs, heart and other parts of the body.
Read the package label carefully and make sure you understand what is written on it. If you are confused about any information, discuss with your doctor for clarification.
