As research progresses, newer biologics and gene therapies are expected to enter the market in the coming years, driving higher spending and expanding the pulmonary hypertension drugs market size significantly.

Pulmonary Hypertension (PH) can be classified into five stages based on the mean pulmonary arterial pressure (mPAP) and cardiac output. Initial treatment typically starts with Group 1 PH medications during Stages 1-3 when mPAP is 25-40 mmHg. Endothelin receptor antagonists (ERAs) such as bosentan (Tracleer) and ambrisentan (Letairis) are often first-line options due to favorable risk-benefit profiles. Phosphodiesterase type-5 inhibitors (PDE-5i) like sildenafil (Revatio) and tadalafil (Adcirca) are also commonly prescribed.

As the disease progresses into Stage 3, dual combination therapy with ERAs and PDE-5i becomes more prevalent to achieve better symptomatic relief. Medications such as riociguat (Adempas), a soluble guanylate cyclase stimulator, start gaining popularity as an add-on drug due to its novel mechanism of action.

For patients in advanced Stages 4-5 with mPAP over 40 mmHg, prostanoids like epoprostenol (Flolan), treprostinil (Tyvaso), and iloprost (Ventavis) provide the most vasodilatory effect and hence, better survival benefits. However, due to their parenteral routes of administration and associated side effects, prostanoids are generally reserved for later lines of treatment.

Hemodynamics, functional status, and adherence also impact drug selection. Overall, prescribers prefer initial oral options but ultimately aim to optimize treatment by balancing efficacy, tolerability, administration convenience and other individual factors.

Pulmonary hypertension has four stages based on symptoms and hemodynamics. Stage I involves mild symptoms with a mean pulmonary artery pressure (mPAP) of 25-30 mmHg at rest. Stage II shows moderate limitations with an mPAP of 31-35 mmHg.

Stage III features severe symptoms with an mPAP of 36-45 mmHg. End-stage/stage IV has very poor prognosis with an mPAP over 45 mmHg.

For stage I, medications like Endothelin receptor antagonists (ERAs) such as ambrisentan (Letairis) or macitentan (Opsumit) are preferred. They work by blocking receptors that cause constriction of blood vessels in the lungs.

Stage II is often treated with prostacyclin analogs like iloprost (Ventavis), treprostinil (Tyvaso), or selexipag (Uptravi). These work directly on the prostacyclin receptor in the lungs to relax vessels.

Stage III may require combining therapies like adding a phosphodiesterase type-5 inhibitor like tadalafil (Adcirca) to an ERA.

Stage IV has a poor prognosis despite treatment. Combinations are used but lung transplantation is the only intervention that prolongs life. Several drug classes in combination are needed to treat more advanced stages due to the complex pathophysiology involved. Selection depends on symptoms, hemodynamics and tolerability for each individual patient.

Drug Innovation Through R&D: Developing novel drugs has been a crucial strategy adopted by leading players to gain a competitive edge. For example, Actelion (now Janssen) launched Opsumit (macitentan) in 2013, the first oral endothelin receptor antagonist (ERA) approved for pulmonary arterial hypertension (PAH). Opsumit was a major breakthrough as it offered improved efficacy and safety over existing ERAs. Its approval and commercial success helped Actelion strengthen its leadership position in the PAH market.

 Targeted Acquisitions: Strategic acquisitions of smaller firms working on new drugs/technologies have reinforced product pipelines.

Commercial Excellence: Leaders invest heavily in specialized sales and marketing teams to drive prescription volumes. For example, Janssen and United Therapeutics deploy a field force of over 200 sales representatives solely dedicated to engage pulmonary specialists. Additionally, patient support programs and nursing services have improved treatment adherence.

The above examples show that combinations of innovative R&D, prudent M&A activity, and exemplary commercialization have enabled companies to introduce multiple novel drugs and capture the majority market share in pulmonary hypertension over the past two decades.
