Salbutamol opens your air passages to allow the other inhalers to work more effectively. A randomized, double-blind, placebo-controlled design was used. Levalbuterol is available as 0.63 mg/3 mL and 1.25 mg/3 mL nebulizer solutions.

Salbutamol acts selectively on the β2-adrenoceptors in airways, activating adenylyl cyclase and increasing cAMP.A 36 year old woman with asthma since childhood, treated with inhaled fluticasone + salmeterol and inhaled salbutamol, had a history of alcoholism, frequent hospitalizations with acute severe asthma, poor adherence to treatment, and misuse of salbutamol. Salbutamol is a drug which is used for symptomatic relief and prevention of bronchospasm due to bronchial asthma, chronic bronchitis, and other chronic bronchopulmonary disorders such as copd. Carefully read your asthma action plan from your nurse or doctor.
A racemic mixture, albuterol is short-acting and is relatively selective for beta-2 adrenoceptor sites. Albuterol is a 50:50 mixture of RIntravenously administered albuterol is not available in the United States.
Therefore, most authors would advocate using beta-agonists in acute symptomatic situations for short periods of time.Albuterol is the cornerstone of treatment for acute exacerbation in patients with acute asthma.

Beta adrenoceptor agonists stimulate the production of cyclic AMP through activation of adenylate cyclase.
Mechanism : Salbutamol is a beta2-adrenergic agonist. It binds therefore to Beta 2 receptors found particularly in the bronchioles of the respiratory system.
Approximately 35% of the infants in one study group with CLD demonstrated significant bronchodilation in response to albuterol.Controversy has arisen over long-term beta-agonist stimulation of nonpulmonary tissues, possible adverse effects of long-term bronchodilation on healing lung tissue, and theoretical concerns over the development of tolerance.

. Most studies show similar responses.Aggressive inhaled β-agonist therapy is preferred to intravenous albuterol because the same end point usually can be achieved with less risk for toxicity.Levalbuterol, 0.63 mg, is equivalent to racemic albuterol, 1.25 mg, for efficacy and side effects. Use of any information is solely at the user's own risk. Salbutamol misuse resulting in death has been reported [41].. A 36 year old woman with asthma since childhood, treated with inhaled fluticasone + salmeterol and inhaled salbutamol, had a history of alcoholism, frequent hospitalizations with acute severe asthma, poor adherence to treatment, and misuse of salbutamol.
The pharmacologic effects of beta2-adrenoceptor agonist drugs are at least in part attributable to stimulation of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3,5 -adenosine monophosphate (cyclic AMP).
Salbutamol is a beta2-adrenergic agonist.
