Trial Type Trial ID Title Status Sponsor Phase Start Date Summary
New Dosage NCT01323010 ↗ Efficacy and Safety of Increasing Doses of Inhaled Albuterol in Children With Acute Wheezing Episodes Completed Fundação de Amparo à Pesquisa do Estado de São Paulo N/A 2011-09-01 Metered dose inhalers with spacers are devices capable of providing higher rates of lung deposition of drugs such as beta agonists when compared to conventional nebulizers, but there is no consensus about the optimal dose when this is the device of choice and there is evidence that younger children need proportionally higher doses of albuterol (in μg/kg) when compared to older children. Other factors that may interfere with response to albuterol treatment include the genetics of the beta adrenergic receptor (ADRβ2) and infectious etiology of the wheezing attack. This study will assess the effectiveness of a dose regimen that prioritizes higher doses of albuterol, with doses in μg/kg higher for younger children. Security of this new dosing regimen will be assessed by monitoring clinical side effects and serum levels of albuterol, but the investigators will also examine the presence of 12 different respiratory viruses in these patients and evaluate the influence of ADRβ2 receptor genetics in the response to albuterol. The primary outcome measure will be the need for hospitalization. Secondary outcomes will include a change in clinical score, respiratory rate and forced expiratory volume in the first second, the need for additional treatments and length of stay in the emergency room for those not hospitalized.

New Combination NCT03906045 ↗ A Scintigraphy Study of PT010 in COPD Patients Completed Simbec Research Phase 1 2019-04-04 This study is a single treatment period, single dose gamma scintigraphy study investigating the deposition in the lungs of a Budesonide, Glycopyrronium and Formoterol Fumarate Metered Dose Inhaler (BGF-MDI). This study will be investigating how the drug (known as PT010) is distributed in the lungs of Chronic Obstructive Pulmonary Disease (COPD) patients (with moderate to very severe COPD) following a maximal 10 second breath hold. This inhaler is intended to be used in the treatment of COPD, which is a group of diseases which cause lung problems and difficulty breathing. PT010 is a new combination product of 3 marketed drugs called Glycopyrronium, Formoterol Fumarate and Budesonide.

All Clinical Trials for VENTOLIN HFA

Trial ID Title Status Sponsor Phase Start Date Summary
NCT00102882 ↗ Study Of Asthma And Genetics In Patients To Be Treated With Fluticasone Propionate/Salmeterol Or Salmeterol Xinafoate Completed GlaxoSmithKline Phase 4 2004-10-01 This study may last up to 36-38 weeks. Patients will visit the clinic 11 times. A blood sample will be taken at Visit 1 to look at subjects' genes. Breathing tests will be done during the study. Study medicines and procedures will be provided at no cost. Patients will be treated with VENTOLIN (8 wks), ATROVENT (8 wks), then ADVAIR or SEREVENT (16 wks). ADVAIR and SEREVENT are FDA approved for the treatment of asthma in patients 4 years of age and older.
NCT00180843 ↗ Assessment of Ventilation-perfusion Abnormalities in Patients With Stable Smoking-related Airways Disease Terminated GlaxoSmithKline N/A 2005-09-01 Subjects undergo history, examination, lung function assessment after informed consent has been obtained. All subjects will undergo ventilation-perfusion scans. If there first scan is normal they will undergo a second and final scan four weeks later. If abnormal they will undergo two further scans with either nebulized bronchodilator or nebulized saline prior to their second and third scans. Each time they will have repeat lung function tests prior to scanning. We will examine the regional changes in ventilation and perfusion and there relationship to lung function.

All subjects will undergo ventilation-perfusion scans. If there first scan is normal they will undergo a second and final scan four weeks later. If abnormal they will undergo two further scans with either nebulized bronchodilator or nebulized saline prior to their second and third scans.

NCT00220259 ↗ Cystic Fibrosis Withdrawal of Inhaled Steroids Evaluation Study (CF WISE Study) Completed Cystic Fibrosis Trust N/A 2001-05-01 The overall aim of this study is to find out whether taking regular inhaled steroids (eg Pulmicort, Flixotide, Becotide, Becloforte) is good for the lungs of children and adults with cystic fibrosis (CF). Some patients are put on inhaled steroids because they are wheezy despite taking regular bronchodilators (inhaled medicines that help open up the airways eg Ventolin, Bricanyl). Occasionally young children are put on them when they wheeze with colds, and have simply remained on them ever since. However many CF patients have been put onto inhaled steroids because their doctors thought it might reduce the inflammation in the lungs and help improve lung function. This inflammation (which is swelling of the lining of the airways) is known to be important in CF and results from recurrent chest infections. Although it is believed, in theory, that inhaled steroids should be useful for most CF patients, we are not sure how well they work in CF and it has not yet been possible to prove this with standard studies. This would normally involve starting inhaled steroids in patients who have not been taking them. We have therefore taken a different approach, namely to withdraw them from some patients who have been on them for a long time, to see if there is any effect of stopping them. It is important that we answer this question, as we do not want CF patients taking medicines that may be unnecessary. CF patients already have to take many oral and inhaled medicines and if we can cut down this burden, it would be helpful for everyone. Of course, we may find that patients do need these medicines but at least we will then be certain that it is for a good reason. The main hypothesis is that withdrawing inhaled steroids is not associated with an earlier onset of acute chest exacerbations.

NCT00220259 ↗ Cystic Fibrosis Withdrawal of Inhaled Steroids Evaluation Study (CF WISE Study) Completed Royal Brompton & Harefield NHS Foundation Trust N/A 2001-05-01 The overall aim of this study is to find out whether taking regular inhaled steroids (eg Pulmicort, Flixotide, Becotide, Becloforte) is good for the lungs of children and adults with cystic fibrosis (CF).

NCT00320034 ↗ Evaluation of the Effect of Levalbuterol on Allergen Induced Airway Inflammation In Subjects With Atopic Asthma Completed Sunovion Phase 2 2006-04-01 The most commonly used drug for immediate relief of symptoms of asthma is the blue puffer, albuterol or salbutamol (Ventolin). Racemic albuterol is a mixture of two forms of albuterol which are mirror images of each other i.e. R-and S- isomers. The investigational treatments are R-albuterol and S-albuterol. R-albuterol ( levalbuterol) has been shown to have a slightly better bronchodilator effect as compared to the racemic albuterol and is well- tolerated in patients. However it is still not clear whether the S-isomer has no effect or has a harmful effect on the airways. The purpose of this study is to compare the effects of the R- and S- isomers on allergen induced airway inflammation in subjects with mild atopic asthma. This will give us a better idea as to whether the routine use of levalbuterol is superior to racemic albuterol.

FAQs

  1. How does VENTOLIN HFA compare to other bronchodilators in terms of efficacy?
    Ventolin HFA has demonstrated comparable efficacy to other short-acting beta-agonists (SABAs) in relieving acute bronchospasm, with fast onset and short duration (~4–6 hours). Its safety profile remains consistent across clinical trials and post-market surveillance.

  2. What ongoing clinical trials may influence future indications for VENTOLIN HFA?
    Trials focusing on pediatric safety, device efficacy, and combination with corticosteroids could broaden its labeled uses or improve delivery methods.

  3. How will generic competition impact VENTOLIN HFA’s market share?
    Generics approved in 2023 are expected to exert pricing pressures and potentially reduce profits for branded versions, though brand loyalty and clinical familiarity sustain market share.

  4. What are significant technological trends affecting inhaler devices?
    Digital inhalers with embedded sensors provide adherence data, improve patient engagement, and inform personalized treatment plans, potentially transforming VENTOLIN HFA’s delivery ecosystem.

  5. Are there environmental concerns impacting VENTOLIN HFA’s future?
    Yes. Pressurized metered-dose inhalers traditionally use hydrofluorocarbon (HFC) propellants, which are greenhouse gases. Regulatory policies are shifting toward greener formulations, influencing product development strategies.
