Albuterol is a white to off-white crystalline solid. It is soluble in ethanol, sparingly soluble in water, and very soluble in chloroform. Ventolin inhalation aerosol is a pressurized metered-dose aerosol unit for oral inhalation. Each actuation delivers 100 mcg of albuterol from the valve and 90 mcg of albuterol from the mouthpiece. The active component in these albuterol inhalation formulations is albuterol sulfate, the racemic form of albuterol and a relatively selective beta 2 -adrenergic bronchodilator.
Albuterol sulfate is a white crystalline powder, soluble in water and slightly soluble in ethanol.
Ventolin inhalation solution contains no sulfiting agents and is a clear, colorless to light yellow solution. Ventolin Nebules inhalation solution contains no sulfiting agents or preservatives and is a clear, colorless solution. Ventolin Rotacaps for inhalation contain a dry powder presentation of albuterol sulfate intended for oral inhalation only. The contents of each capsule are inhaled using a specially designed plastic device for inhaling powder called the Rotahaler. When turned, this device opens the capsule and facilitates dispersion of the albuterol sulfate into the airstream created when the patient inhales through the mouthpiece.
