What is Isoprenaline used for?
What is Isoprenaline used for?
Isoprenaline, or isoproterenol (Brand name: Isoprenaline Macure), is a medication used for the treatment of bradycardia (slow heart rate), heart block, and rarely for asthma. It is a non-selective β adrenoceptor agonist that is the isopropylamine analog of epinephrine (adrenaline).
What is isoproterenol used to treat?
Isuprel (isoproterenol hydrochloride) is a bronchodilator used as an inhaler to treat conditions such as asthma, bronchitis, and emphysema. In rare cases, Isuprel is given as an injection as a treatment for electrical heart block.
Does isuprel increase blood pressure?
Systolic blood pressure may remain unchanged or rise, although mean arterial pressure typically falls. Cardiac output is increased because of the positive inotropic and chronotropic effects of the drug in the face of diminished peripheral vascular resistance.
What does isoproterenol do to the heart?
Absolute Contraindications Isoproterenol requires caution in patients with the following: Cardiovascular disease: Isoproterenol causes an increase in myocardial oxygen demand. Diabetes: May cause an increase in blood glucose levels. Distributive shock: Beta-2 agonism will further decrease total peripheral resistance.
What kind of drug is Isoprenaline?
Isoprenaline is a non-selective β-adrenergic agonist. It has positive inotropic and chronotropic effects, increasing cardiac output by increasing the heart rate and cardiac contractility. Isoprenaline also decreases diastolic blood pressure by lowering peripheral vascular resistance.
What does isoproterenol do to blood pressure?
Isoproterenol dilates skeletal, renal, and mesenteric vascular beds and decreases diastolic blood pressure.
How does atropine work?
Atropine reduces secretions in the mouth and respiratory passages, relieves the constriction and spasm of the respiratory passages, and may reduce the paralysis of respiration that results from toxic nerve agents which increase anticholinesterase activity in the central nervous system.
Is isoproterenol still used?
Consequently, isoproterenol has been used to treat heart block, cardiac arrest, asthma, and bronchospasm. The therapeutic use of isoproterenol has been replaced to a great extent by drugs that have greater selectivity for individual beta adrenoceptor subtypes Hoffman (2001).
Why does isoproterenol decrease blood pressure?
Isoproterenol, a beta agonist, would cause a decrease in blood pressure by vasodilation; therefore, choices A, B, and C can be immediately eliminated. The decrease in heart rate is due to a baroreceptor reflex. The increased blood pressure leads to increased parasympathetic and decreased sympathetic tone to the heart.
Does labetalol cause anxiety?
Labetalol may also diminish libido, cause anxiety and induce insomnia.
