Activation of β adrenergic receptors leads to relaxation of smooth muscle in the lung, and dilation and opening of the airways. β adrenergic receptors are coupled to a stimulatory G protein of adenylyl cyclase. This enzyme produces the second messenger cyclic adenosine monophosphate (cAMP).
What are Saba drugs?
Short-acting beta-agonists (SABAs) are a class of prescription drugs used to quickly relieve shortness of breath and wheezing in people with asthma.

Why do sabas dilate the airways?
When this happens, it causes the muscles wrapped around airways to spasm. This causes the airways to become narrowed. It makes breathing difficult. SABAs prevent acetylcholine from doing its job. In this way, they dilate airways to make breathing easier. But, they only last 4-6 hours, hence the term “Short-Acting.”

What They Are
How Sabas Work
- SABAs, along with closely related long-acting beta-agonists (LABAs), belong to a class of drugs known as beta2 (β2)-adrenergic receptor agonists. By definition, agonists are drugs that bind to a cell receptor to trigger a specific reaction. The receptor in this case is the beta2-adrenergic receptor, which relaxes smooth muscles. Smooth muscles are those in the walls of hollow orga…
Indications For Use
- How SABAs are used to treat asthma depends on the frequency or severity of symptoms: 1. Mild intermittent asthma: SABAs are often used on their own as needed. 2. Persistent asthma: SABAs typically are used to relieve acute symptoms; inhaled LABAs and/or corticosteroidsare also taken on a regular (typically daily) basis to provide long-term control. 3. Exercise-induced asthma: SAB…
Precautions and Contraindications
- There are few absolute contraindications to SABAs other than a known allergy to the drug or an inactive ingredient in the formulation. If you are allergic to albuterol, you should not use levalbuterol (or vice versa).11 SABAs are known to affect pulse rate, blood pressure, blood sugar, and thyroid hormone production and, on rare occasions, induce seizures. While not contraindica…
Dosage
- The recommended dosage of albuterol and levalbuterol varies according to the formulation as well as the age of the person who will be taking it. Among the approved formulations: 1. Albuterol is available as a metered-dose inhaler (MDI), dry powder inhaler (DPI), nebulized solution, immediate-release (IR) tablet, extended-release (ER) tablet, syrup, and intravenous solution. 2. L…
Side Effects
- The side effects of the various SABA formulations are largely the same. However, because inhaled SABAs are delivered straight to the lungs and therefore do not affect other organs in the body, they tend to have milder and shorter-lasting side effects than oral or intravenous SABAs.13
Warnings and Interactions
- Routine monitoring of heart function, blood glucose, or thyroid functionis recommended for anyone in an at-risk group who takes albuterol. The treatment may need to be stopped if symptoms worsen or diagnostic test results fall well outside of the acceptable range of values. Because of their effect on heart rhythms, never use more of an SABA than prescribed. On rare o…
A Word from Verywell
- Though rescue inhalers like albuterol and levalbuterol are safe and effective for relieving acute asthma symptoms, it is important not to overuse them. Some people will do out so of panic if the drug is "not working fast enough," while others will overuse SABAs to avoid having to take other longer-acting drugs. Both of these are signs that your condition is not being well controlled. As …
