Proair HFA (Albuterol Sulfate Inhalation Aerosol) Drug Information

Mechanism of Action. Albuterol sulfate is a beta2-adrenergic agonist. The pharmacologic effects of albuterol sulfate are attributable to activation of.

No pharmacokinetic studies for PROAIR HFA (albuterol sulfate inhalation aerosol) Inhalation Aerosol have been conducted in neonates or elderly subjects.

Serial FEV 1 measurements, expressed as the baseline-adjusted percent predicted FEV 1 observed over 6 hours post-dose, demonstrated that one and two inhalations of PROAIR HFA (albuterol sulfate inhalation aerosol) Inhalation Aerosol produced significantly greater bronchodilator responses than the matched placebo. In a placebo-controlled, single-dose, crossover study in 55 pediatric patients 4 to 11 years of age, PROAIR HFA (albuterol sulfate inhalation aerosol) Inhalation Aerosol, administered at albuterol doses of 90 and 180 mcg, was compared with a matched placebo HFA inhalation aerosol.

The effect of hepatic impairment on the pharmacokinetics of PROAIR HFA (albuterol sulfate inhalation aerosol) Inhalation Aerosol has not been evaluated.

In a placebo-controlled, single-dose, crossover study, PROAIR HFA (albuterol sulfate inhalation aerosol) Inhalation Aerosol, administered at albuterol doses of 90, 180 and 270 mcg, produced bronchodilator responses significantly greater than those observed with a matched placebo HFA inhalation aerosol and comparable to a marketed active comparator HFA-134a albuterol inhaler.

Some patients who participated in these clinical trials were using concomitant steroid therapy.

Ventolin HFA (Albuterol Sulfate Inhalation Aerosol) Drug Information

Mechanism of Action. In vitro studies and in vivopharmacologic studies have demons trated that albuterol has a preferential effect on beta2-adrenergic receptors.

This increase of cyclic AMP leads to the activation of protein kinase A, which inhibits the phosphorylation of myosin and lowers intracellular ionic calcium concentrations, resulting in relaxation. Albuterol relaxes the smooth muscles of all airways, from the trachea to the terminal bronchioles. Albuterol acts as a functional antagonist to relax the airway irrespective of the spasmogen involved, thus protecting against all bronchoconstrictor challenges. Activation of beta 2 -adrenergic receptors on airway smooth muscle leads to the activation of adenylcyclase and to an increase in the intracellular concentration of cyclic-3', 5' -adenosine monophosphate (cyclic AMP).

Albuterol Sulfate. Mechanism of Action. In vitro and in vivo pharmacologic studies have demonstrated that albuterol has a preferential effect on beta2-adrenergic.

At recommended doses, ipratropium bromide does not produce clinically significant changes in pulse rate or blood pressure. Ventilation/perfusion studies have shown no clinically significant effects on pulmonary gas exchange or arterial oxygen tension.

The chemical formula is (C 13 H 21 NO 3 ) 2 ·H 2 SO 4, and the molecular weight is 576.7. Albuterol sulfate is a white to off-white crystalline powder soluble in water and slightly soluble in ethanol. Albuterol is the official generic name in the US.

Albuterol Inhalation Solution - FDA prescribing information, side

The action of albuterol sulfate inhalation solution may last up to 6 hours or longer. Albuterol sulfate inhalation solution should not be used more frequently than.

Monoamine Oxidase Inhibitors or Tricyclic Antidepressants: Albuterol should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, or within 2 weeks of discontinuation of such agents, because the action of albuterol on the vascular system may be potentiated.

FOR ORAL INHALATION ONLY.

*Potency expressed as albuterol Rx only.

Albuterol has been shown in most controlled clinical trials to have more effect on the respiratory tract, in the form of bronchial smooth muscle relaxation, than isoproterenol at comparable doses while producing fewer cardiovascular effects.

Diuretics: The ECG changes and/or hypokalemia that may result from the administration of nonpotassium-sparing diuretics (such as loop or thiazide diuretics) can be acuy worsened by beta-agonists, especially when the recommended dose of the beta-agonist is exceeded.
