A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Chemical Name ALBUTEROL (al-BYOO-ter-ole)
PROAIR HFA is a medication prescribed to treat both bronchospasms in reversible obstructive airway disease (asthma) and to prevent exercise-induced bronchospasms. PROAIR HFA can be used in patients that are four years of age or older.
In patients with asthma and exercise-induced bronchospasms, the lungs constrict and tighten, making it difficult to take a full breath.
Albuterol works by attaching to beta-receptors on the surface of smooth muscle cells in the lungs. When albuterol attaches to beta-receptors, it causes the muscles that line lung tissue to relax, making it easier to breathe.
The normal dosage is Inhale one to two puffs every four to six hours as needed for coughing or wheezing. Your instructions may vary depending on your indication and the severity of your disease.
PROAIR HFA and other albuterol inhalers may be used for acute bronchospasms.
The active ingredient in PROAIR HFA is albuterol sulfate.
Each actuation contains 108 micrograms (mcg) of albuterol sulfate, equivalent to 90 mcg of albuterol base.
Each PROAIR HFA 90 mcg inhaler is 8.5 grams and contains 200 actuations.
