What is Ventolin HFA?
Ventolin HFA is a prescription inhaled medicine used in people aged 4 years and older to treat or prevent bronchospasm in people who have reversible obstructive airway disease, prevent exercise-induced bronchospasm
It is not known if Ventolin HFA is safe and effective in children younger than 4 years of age.
The active component of VENTOLIN HFA is albuterol sulfate, USP, the racemic form of albuterol and a relatively selective beta2-adrenergic bronchodilator. Albuterol sulfate has the chemical name α1-[(tert-butylamino)methyl]-4-hydroxy-m-xylene-α, α′-diol sulfate (2:1)(salt) and the following chemical structure:
Albuterol sulfate is a white crystalline powder with a molecular weight of 576.7, and the empirical formula is (C13H21NO3)2•H2SO4. It is soluble in water and slightly soluble in ethanol.
The World Health Organization recommended name for albuterol base is salbutamol.
VENTOLIN HFA is a blue plastic inhaler with a blue cap containing a pressurized metered-dose aerosol canister fitted with a counter. Each canister contains a microcrystalline suspension of albuterol sulfate in propellant HFA-134a (1,1,1,2-tetrafluoroethane). It contains no other excipients.
After priming, each actuation of the inhaler delivers 120 mcg of albuterol sulfate, USP in 75 mg of suspension from the valve and 108 mcg of albuterol sulfate, USP from the mouthpiece (equivalent to 90 mcg of albuterol base from the mouthpiece).
Prime VENTOLIN HFA before using for the first time, when the inhaler has not been used for more than 2 weeks, or when the inhaler has been dropped. To prime VENTOLIN HFA, release 4 sprays into the air away from the face, shaking well before each spray. Avoid spraying in eyes.
Mechanism of Action
In vitro studies and in vivo pharmacologic studies have demonstrated that albuterol has a preferential effect on beta2-adrenergic receptors compared with isoproterenol. Although beta2-adrenoceptors are the predominant adrenergic receptors in bronchial smooth muscle and beta1-adrenoceptors are the predominant receptors in the heart, there are also beta2-adrenoceptors in the human heart comprising 10% to 50% of the total beta-adrenoceptors. The precise function of these receptors has not been established, but their presence raises the possibility that even selective beta2-agonists may have cardiac effects.
Activation of beta2-adrenergic receptors on airway smooth muscle leads to the activation of adenyl cyclase and to an increase in the intracellular concentration of cyclic-3′,5′-adenosine monophosphate (cyclic AMP). 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. Increased cyclic AMP concentrations are also associated with the inhibition of release of mediators from mast cells in the airway.
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. Controlled clinical studies and other clinical experience have shown that inhaled albuterol, like other beta-adrenergic agonist drugs, can produce a significant cardiovascular effect in some patients, as measured by pulse rate, blood pressure, symptoms, and/or electrocardiographic changes

Instructions for use for Ventolin HFA
Ventolin (VENT o lin) HFA
(albuterol sulfate inhalation aerosol)
For oral inhalation use
Your Ventolin HFA inhaler
- The metal canister holds the medicine. See Figure A.
- The metal canister has a counter to show how many sprays of medicine you have left. The number shows through a window in the back of the plastic actuator. See Figure A.
- The counter starts at either 204 or 064, depending on which size inhaler you have. The number will count down by 1 each time you spray the inhaler. The counter will stop counting at 000.
- Do not try to change the numbers or take the counter off the metal canister. The counter cannot be reset, and it is permanently attached to the metal canister.
- The blue plastic actuator sprays the medicine from the metal canister. The plastic actuator has a blue protective cap that covers the mouthpiece. See Figure A. Keep the protective cap on the mouthpiece when the metal canister is not in use.
- Do not use the plastic actuator with a canister of medicine from any other inhaler.
- Do not use a Ventolin HFA metal canister with an actuator from any other inhaler.
Before using your Ventolin HFA inhaler
- The inhaler should be at room temperature before you use it.
- If your child needs to use Ventolin HFA, watch your child closely to make sure your child uses the inhaler correctly. Your healthcare provider will show you how your child should use Ventolin HFA.
Priming your Ventolin HFA inhaler
Before you use Ventolin HFA for the first time, you must prime the inhaler so that you will get the right amount of medicine when you use it.
- To take the cap off the mouthpiece, squeeze the sides of the cap and pull out. See Figure B.
- Shake the inhaler well.
- Spray the inhaler 1 time into the air away from your face. Avoid spraying in eyes. See Figure C.
- Shake and spray the inhaler like this 3 more times to finish priming it. The counter should now read 200 or 060, depending on which size inhaler you have. See Figure D.
- You must prime your inhaler again if you have not used it in more than 14 days or if you have dropped it. Take the cap off the mouthpiece and shake and spray the inhaler 4 times into the air away from your face.
How to use your Ventolin HFA inhaler
Follow these steps every time you use Ventolin HFA.
Step 1. Make sure the metal canister fits firmly in the plastic actuator. The counter should show through the window in the plastic actuator.
To take the cap off the mouthpiece, squeeze the sides of the cap and pull out. Look inside the mouthpiece for foreign objects and take out any you see.
Step 2. Hold the inhaler with the mouthpiece down and shake it well. See Figure E.
Step 3. Breathe out through your mouth and push as much air from your lungs as you can. See Figure F.
Step 4. Put the mouthpiece in your mouth and close your lips around it. Push the top of the metal canister firmly all the way down while you breathe in deeply and slowly through your mouth. See Figure G.
Step 5. After the spray comes out, take your finger off the metal canister. After you have breathed in all the way, take the inhaler out of your mouth and close your mouth.
Step 6. Hold your breath for about 10 seconds, or for as long as is comfortable. Breathe out slowly as long as you can.
If your healthcare provider has told you to use more sprays, wait 1 minute and shake the inhaler again. Repeat Steps 2 through Step 6.
Put the cap back on the mouthpiece after you finish using the inhaler. Make sure it snaps firmly into place.
Cleaning your Ventolin HFA inhaler
Clean your inhaler at least 1 time each week. You may not see any medicine build-up on the inhaler, but it is important to keep it clean so medicine build-up will not block the spray. See Figure H.
Step 7. Take the canister out of the plastic actuator and take the cap off the mouthpiece by squeezing the sides of the cap and pulling it straight out.
Step 8. Hold the actuator under the faucet and run warm water through it for about 30 seconds. See Figure I.
Step 9. Turn the actuator upside down and run warm water through the mouthpiece for about 30 seconds. See Figure J.
Step 10. Shake off as much water from the plastic actuator as you can. Look into the mouthpiece to make sure any medicine build-up has been completely washed away. If there is any build-up, repeat Steps 8 and 9.
Step 11. Let the actuator air-dry overnight. See Figure K.
Step 12. When the plastic actuator is dry, put the protective cap on the mouthpiece and then put the canister in the plastic actuator and make sure it fits firmly. Shake the inhaler well, remove the cap, and spray the inhaler 1 time into the air away from your face. (The counter will count down by 1 number.) Put the cap back on the mouthpiece.
If you need to use your inhaler before the plastic actuator is completely dry:
- Shake as much water off the plastic actuator as you can.
- Put the cap on the mouthpiece and then put the canister in the plastic actuator and make sure it fits firmly.
- Shake the inhaler well, remove the cap, and spray it 1 time into the air away from your face.
- Take your Ventolin HFA dose as prescribed.
- Follow cleaning Steps 7 through 12 above.
Replacing your Ventolin HFA inhaler
- When the counter reads 020, you should refill your prescription or ask your healthcare provider if you need another prescription for Ventolin HFA.
- When the counter reads 000, throw the inhaler away. You should not keep using the inhaler when the counter reads 000 because you will not receive the right amount of medicine.
- Do not use the inhaler after the expiration date, which is on the packaging it comes in.
For correct use of your Ventolin HFA inhaler, remember:
- The metal canister should always fit firmly in the plastic actuator.
- Breathe in deeply and slowly to make sure you get all the medicine.
- Hold your breath for about 10 seconds after breathing in the medicine. Then breathe out fully.
- Always keep the protective cap on the mouthpiece when your inhaler is not in use.
- Always store your inhaler with the mouthpiece pointing down.
- Clean your inhaler at least 1 time each week.
