The global pulmonary arterial hypertension market size was valued at USD 5.89 billion in 2022. It is estimated to reach USD 9.53 billion by 2031, growing at a CAGR of 5.50% during the forecast period (2023–2031).
The rise in the incidents of Pulmonary Arterial Hypertension (PAH) and the growing geriatric population are the factors stimulating pulmonary arterial hypertension market growth.
Pulmonary arterial hypertension is a rare and severe illness characterized by elevated blood pressure in the arteries supplying the lungs. It occurs when the pulmonary arteries, the small blood vessels in the lungs, become narrow, blocked, or damaged. This leads to increased pressure in these arteries, making the heart pump blood through the lungs harder. PAH can be categorized into different types, including idiopathic (no known cause), heritable (caused by genetic factors), and associated with other conditions like connective tissue diseases or congenital heart defects.
Symptoms of PAH can vary and may include shortness of breath, fatigue, chest pain, dizziness, fainting, and feet, legs, and stomach swelling. Over time, these symptoms may worsen and significantly impact a person's quality of life. PAH is a progressive disease that can result in complications such as right-sided heart failure, arrhythmias, blood clots in the lungs, and, in severe cases, death. Therefore, early diagnosis and treatment are vital for effectively managing the condition. Regular monitoring by a specialized healthcare team, including pulmonologists, cardiologists, and other specialists, is crucial for individuals with PAH. They can monitor the condition, adjust medications, and provide the necessary support. Lifestyle modifications, such as regular exercise, a balanced diet, and avoiding smoking and respiratory irritants, may also be recommended to manage the condition effectively.
Pulmonary arterial hypertension (PAH) is indeed classified as a rare disorder, with a relatively low global prevalence of approximately 15 to 50 cases per million people. This means that in a given population, only a small number of individuals are diagnosed with PAH. Cumulatively, the number of new cases reported each year ranges from 100,000 to 200,000 worldwide. PAH can also occur in association with other underlying diseases. It is frequently viewed as a harmful lung and cardiac disorder. For instance, individuals with chronic obstructive pulmonary disease (COPD), interstitial lung disease, or pulmonary fibrosis have a higher risk of developing PAH.
Congenital heart disorders, such as atrial septal defect or ventricular septal defect, can also contribute to the development of PAH. Additionally, coronary artery disease, blood clots in the lungs, and high blood pressure can be underlying causes of PAH. It's important to note that while these conditions may increase the risk of PAH, not everyone with these factors will develop the disorder. The exact mechanisms by which these conditions lead to the development of PAH are still being studied.
The presence of a large population over sixty years, which has lower immunity levels and is prone to PAH and associated diseases, is a high impact-rendering driver for the growth of the PAH market over the forecast period. Although the onset age for PAH is 45 years, it is frequently observed to occur in populations above 60 years of age. This population is expected to avail the best possible treatments, increasing the life span. The chart below forecasts the number of geriatric patients over the next six years who may form a routine target group contributing toward the increasing demand for PAH drugs.
Healthcare professionals, policymakers, and the pharmaceutical industry need to recognize this trend and allocate resources accordingly to ensure the availability and accessibility of appropriate treatments for this population. By addressing the specific needs of the aging population and providing effective management of PAH, we can contribute to improved healthcare outcomes and enhanced quality of life for these individuals.
Loss of exclusivity has a direct impact on the market of branded pharmaceutical products. Also, with the Drug Price Competition and Patent Term Restoration Act of 1984, informally known as the Hatch-Waxman Act, the development of generic drugs is encouraged, which impacts the sale of branded molecules. The license expiry of some blockbuster drugs is making way for generic drug penetration. The increased sales of generic drugs adversely affect the overall revenue generation of the market since it is 70 to 80 percent cheaper as compared to branded drugs. Cutting-edge therapies are developed for treating PAH. Therefore, the future of the market is presumed to be brighter in the years to come.
The development of drugs stimulating soluble guanylate cyclase (SGC) represents a significant opportunity in the global pulmonary arterial hypertension market. Soluble guanylate cyclase is an enzyme involved in cyclic guanosine monophosphate (cGMP) production, which is crucial in regulating blood vessel dilation and maintaining vascular tone. In PAH, the production or response is deficient to cGMP, leading to vasoconstriction and increased blood pressure in the pulmonary arteries.
By targeting and stimulating soluble guanylate cyclase, drugs can enhance cGMP production, promoting vasodilation and reducing the elevated pulmonary artery pressure associated with PAH. The global market opportunity for SGC stimulators in PAH is significant, as there is a growing demand for more effective and targeted therapies for this rare disease. PAH is a chronic and progressive condition that requires lifelong management, and currently available treatments have limitations in terms of efficacy and tolerability.

The global pulmonary arterial hypertension market is bifurcated into drug classes.
Based on drug class, the global pulmonary arterial hypertension market is bifurcated into prostacyclin and prostacyclin analogs, SGC stimulators, ERA, and PDE-5.
The prostacyclin and prostacyclin analogs segment dominates the global market and is projected to exhibit a CAGR of 4.2% over the forecast period. Prostacyclin is a potent vasodilator and one of the most effective drugs for treating PAH. It is produced from arachidonic acid through the Cyclooxygenase (COX) pathway and is released by endothelial cells in the pulmonary artery. Prostacyclin binds to the prostaglandin receptors to promote the relaxation of smooth muscles and vasodilation by activating G protein and protein kinase. Prostacyclin levels are reduced in PAH patients, reducing dilatory and antiproliferative effects.
Prostacyclin analogs and IP receptor agonists have been approved to target the prostacyclin pathway in PAH patients. Iloprost (Ventavis), Epoprostenol (Flolan and Veletri), and Treprostinil (Remodulin, Tyvaso, and Orenitram) are some of the drugs from this category approved for use in PAH patients. Drugs from the prostacyclin and analogs segment are expected to rise significantly over the anticipated period, primarily due to the opportunities presented in the oral prostacyclin subsegment (e.g., Uptravi and Orenitram).
