Rising Prevalence of Asthma and Chronic Obstructive Pulmonary Disease
Health issues like asthma and COPD are taken very seriously. A sizable fraction of the world's population is impacted by them. Asthma and chronic obstructive pulmonary disease (COPD) share several risk factors, including smoking, cigarette use, and environmental pollution.
The American Lung Association reports that smoking is the leading cause of COPD and accounts for around 80% of COPD-related fatalities.
Over 360 and 19.1 million individuals suffered from asthma and COPD in 2020, respectively, according to the Global Burden of Disease Study. Asthma and chronic obstructive pulmonary disease are becoming more common as a result of the improved living standards seen in industrialized nations.
But in poorer nations, where air pollution and smoking are more common, these diseases are more common among the population.
Market growth for generic inhalers and nasal sprays is anticipated to be bolstered by an aging population with chronic respiratory diseases, including COPD and asthma.
Market Growth of Generic Drugs May Be Stifled by Strict Regulations
As more and more low-price generic inhalation and nasal spray medications become available around the world, different regulatory authorities have opted for stringent criteria to focus on quality.
Brazil, Mexico, and Russia are just a few of the emerging countries whose regulatory bodies have recently revised their policies on the sale of generic pharmaceuticals.
The sales of inhalation and nasal spray generic drugs in the global market have been significantly slowed as a result of the new regulatory standards.
Additionally, several pharmaceutical businesses operating in Russia are facing challenges due to the country's new regulatory legislation, which requires clinical trials for generic drugs. Similarly, the Drugs Controller General of India, the country's domestic drug regulatory organization, established several new drug advisory groups to monitor clinical studies, approve new drugs, etc.
Therefore, the demand for inhalation and nasal spray generic drugs is expected to grow slowly as a result of the tough and strict rules imposed by various developing countries.
With widespread use for the treatment of respiratory illnesses like asthma and COPD, bronchodilators are expected to represent over 25.0% of the market by 2024. Asthma and chronic obstructive pulmonary disease (COPD) are on the rise, which is also fueling.
According to the World Health Organization (WHO), in 2020, there were over 26.9 million individuals living with asthma worldwide. The Asthma and Allergy Foundation of America estimates that by 2024, over 25 million people in the United States are likely to have asthma.
As a result, the market is likely to be driven by the increasing demand for bronchodilators.
For the duration of the forecast, the market for combination pharmaceuticals is anticipated to grow at a compound annual rate of 9.85%. Combination medicine launched by major companies like Apotex Inc. and Teva Pharmaceutical Industries Ltd. is responsible for most of this expansion.
When it comes to treating allergic rhinitis, for instance, Apotex Inc. introduced a generic version of Dymista (azelastine and fluticasone) nasal spray, originally developed by Meda Pharmaceuticals, in March 2024.
In 2024, retail pharmacies' share of total revenue was over 55.0% due to rising healthcare costs and robust sales of generic drugs. In the United States, for instance, generic medications accounted for almost 90% of prescriptions filled in 2020.
Further, the average profit margin of generics in pharmacies is around 43%, indicating high income. The cost of pharmaceuticals has also risen steadily over time. Examples include a 4.9% increase in pharmaceutical spending in the United States between 2020 and 2024.
The sales of inhalation and nasal spray generic drugs by online pharmacies are projected to expand over the coming years. Patients can benefit greatly from the availability and convenience of online pharmacies.
