Flunisolide: Detailed Review of its Transformative R&D Success, Mechanism of Action, and Drug Target
Flunisolide's R&D Progress
Flunisolide is a small molecule drug that targets the glucocorticoid receptor (GR). It is primarily used in the treatment of asthma, a respiratory disease that affects the immune system. The drug was first approved for use in the United States in September 1981.
Flunisolide is classified as a small molecule drug, which means it is composed of relatively low molecular weight compounds. This type of drug is typically orally administered and can easily penetrate cell membranes, allowing it to interact with specific targets within the body.
The main target of flunisolide is the glucocorticoid receptor (GR). Glucocorticoids are a class of steroid hormones that play a crucial role in regulating immune and inflammatory responses. By targeting the GR, flunisolide can modulate these responses, providing relief for patients with immune system diseases and respiratory diseases such as asthma.
Asthma is a chronic condition characterized by inflammation and narrowing of the airways, leading to symptoms such as wheezing, coughing, and shortness of breath. Flunisolide, as an approved treatment for asthma, helps to reduce airway inflammation and improve lung function, thereby alleviating these symptoms.
The drug was originally developed by IVAX LLC, an organization that specializes in the research and development of pharmaceutical products. IVAX LLC successfully obtained global approval for flunisolide.
The first approval of flunisolide occurred in the United States in September 1981. This suggests that the drug has a long history of use in the treatment of asthma in the US market. The specific indications for which flunisolide is approved may vary across different countries or regions.

Mechanism of Action for Flunisolide: GR agonists
From a biomedical perspective, GR agonists refer to substances or drugs that activate the glucocorticoid receptor (GR). The GR is a type of nuclear receptor that is primarily activated by cortisol, a hormone produced by the adrenal glands. When activated, the GR regulates various physiological processes, including metabolism, immune response, and stress response.
GR agonists can mimic the effects of cortisol by binding to the GR and initiating a cascade of cellular events. These agonists are used in medicine for their anti-inflammatory and immunosuppressive properties. They are commonly prescribed for conditions such as asthma, rheumatoid arthritis, and certain autoimmune disorders.
By activating the GR, GR agonists can modulate gene expression and regulate the production of anti-inflammatory proteins. This helps to reduce inflammation and suppress the immune system, which can be beneficial in managing chronic inflammatory diseases.
It is important to note that while GR agonists can be effective in treating certain conditions, prolonged or excessive use of these drugs can lead to side effects such as adrenal suppression, osteoporosis, and increased susceptibility to infections. Therefore, their use should be carefully monitored and prescribed by healthcare professionals.
Drug Target R&D Trends for Flunisolide
According to Patsnap Synapse, as of 17 Sep 2023, there are a total of 348 GR drugs worldwide, from 463 organizations, covering 427 indications, and conducting 11845 clinical trials.
The analysis of the target GR reveals a competitive landscape with multiple companies showing growth and development in the pharmaceutical industry. Novartis AG stands out with the highest stage of development and a significant number of approved drugs. Indications such as Eczema, Asthma, and Psoriasis have seen substantial progress in drug development. Small molecule drugs dominate the drug types, while biosimilars like Antibody drug conjugates (ADCs) and Monoclonal antibodies indicate intense competition. The United States and China are leading in terms of approved drugs, with China showing notable progress. Overall, the target GR presents opportunities for further development and competition in the pharmaceutical industry.
