What is isoproterenol?

isoproterenol, also called isoproterenol hydrochloride or isuprel, is a drug that is structurally similar to epinephrine. It helps to relax smooth muscles and increases the activity in the heart. The opening of bronchial pathways that limits, while the patient is under anesthesia is the most common use for this medicine. It starts to work quickly and wears it within a few hours.

patients experiencing bronchospasm may have isoproterenol to facilitate breathing. Bronchospasm can be caused by an allergic reaction, asthma attack or as a symptom of the disease. In this state, small air passages are called bronchioles, which are usually only about 0.04 inches (1 mm) in diameter, limiting under the pressure of the muscles around them. Patients who are under anesthesia may be threatened by bronchospasm and isoproterenol can be administered while the patient is unconscious to be against this condition.

The body has its own medicine for this condition, in the form of adrenaline. This hormone helps the airways dilatatovaT, but once adrenaline is used, it is possible for the airways to close again. Drugs similar to epinephrine to isoproterenol, act in a similar way to adrenaline, open limited airways and allow the patient to breathe normally.

isoproterenol is also occasionally administered to patients who have suffered cardiac arrest, either as a treatment of a gap in stop until defibrillation is administered or as a treatment if defibrillation is not unnecessary. In addition, this drug can be used as part of the treatment of patients who are in shock. In some cases, the drug may also be administered as an inhalant to control symptoms in patients who have chronic bronchitis or asthma.

Unlike epinephrine, isoproterenol specifically focuses only on certain P receptors in the body. It binds to both β _{1 and β 2 receptors that increase heart rate and release smooth muscles around Bronchial passages. Epinephrine also stimulates these same P receptors, although it also focuses on certain and receptors.}

isoproterenol begins to work in minutes. After administration, open bronchial passages of the patient are increasing, heart rate and diastolic blood pressure increases, which makes it easier to flow through blood. Many patients can also experience heart palpitations, increased vigilance and nervousness. The reason is that the drug mimics adrenaline, which is responsible for the reaction of "fighting or flight". The effects of isoproterenol wear within approximately three hours.
