Salbutamol, also known as albuterol and sold under the brand name Ventolin among others, [1] is a medication that opens up the medium and large airways in the lungs. [8] It is a short-acting β 2 adrenergic receptor agonist that causes relaxation of airway smooth muscle . [ 8 ]
“It will open the airways but not have as much of an effect on blood pressure and heart rate. ... “It is relatively weak in the treatment of asthma, but may help treat allergic rhinitis ...
This results in what is called pulmonary venous hypertension (PVH), and results in distention and recruitment of pulmonary capillaries to help distribute the increased pressure gradient. [ 2 ] [ 4 ] At the capillary, there is a microvascular barrier that helps regulate fluid status via molecular pressure forces such as forces that push outward ...
Treatment depends on the type of heart rhythm shown on an electrocardiogram test, and the stability of the patient's blood circulation. If a patient has low blood pressure, difficulty breathing, chest pain, shock, or confusion, they are considered unstable and must have an electrocardiogram result checked to determine if the heart is beating ...
Frequent coughing, chest tightness and breathing difficulties are also signs of asthma worsening. These symptoms can interfere with a patient's daily living and affect quality of life. These 5 levels are indicators of what drug treatments should be administered. The guideline is as follows: [2] Step 1-2: Symptoms less than 4–5 days a week
LABAs are designed to reduce the need for shorter-acting β 2 agonists such as salbutamol (albuterol), as they have an approximately twelve-hour duration of action, compared to about five hours for salbutamol, making them candidates for sparing high doses of corticosteroids [citation needed] or treating nocturnal asthma and providing ...
Supraventricular tachycardia (SVT) is an umbrella term for fast heart rhythms arising from the upper part of the heart. [2] This is in contrast to the other group of fast heart rhythms – ventricular tachycardia, which start within the lower chambers of the heart. [2]
A 2013 systematic review of the drug's use as a treatment for acute asthma found that it "was not superior to albuterol regarding efficacy and safety in subjects with acute asthma." The review concluded: "We suggest that levalbuterol should not be used over albuterol for acute asthma." [2] Levalbuterol is notably more costly. [4] [5]
