Introduction
Global Inhalable Drugs Market size is expected to be worth around USD 32.4 billion by 2023 from USD 60.8 billion in 2033, growing at a CAGR of 6.5% during the forecast period 2024 to 2033.
Inhalable drugs, which are administered directly into the lungs through inhalation, are gaining traction in the pharmaceutical market. These drugs are available in various forms, including metered-dose inhalers (MDIs), dry powder inhalers, and nebulizers. They offer multiple benefits such as lower medication doses that reduce side effects, rapid action for emergency treatments like asthma attacks, needle-free administration suitable for those with a fear of needles, and portability, making them ideal for active individuals and frequent travelers.
The market for inhalable drugs is expanding, driven by the rising prevalence of non-respiratory diseases such as Parkinson’s disease and diabetes that can benefit from this form of delivery. Furthermore, the increasing elderly population and advancements in inhalable drug therapies are boosting the market’s growth. The method’s advantages over oral and parenteral administration, such as avoiding the digestive system and direct delivery into the lungs, also contribute to its popularity.
According to the World Health Organization, tuberculosis (TB) remains a significant global health threat, with 1.3 million fatalities in 2022, including 167,000 among individuals with HIV. This positions TB as the second leading infectious killer globally, following COVID-19 and surpassing HIV/AIDS. In the same year, around 10.6 million people were diagnosed with TB, encompassing 5.8 million men, 3.5 million women, and 1.3 million children, demonstrating that TB affects all countries and age groups. Despite being both curable and preventable, TB continues to pose challenges, particularly with multidrug-resistant TB (MDR-TB), which is a public health crisis and a health security threat.
Remarkably, only about 40% of those with drug-resistant TB received treatment in 2022. Since 2000, global efforts against TB have been fruitful, saving an estimated 75 million lives. However, substantial resources are still required, with an annual need of US$ 13 billion for TB prevention, diagnosis, treatment, and care to meet the targets set during the 2018 UN high-level meeting on TB. Ultimately, ending the TB epidemic by 2030 is a key health target under the United Nations Sustainable Development Goals (SDGs).
