Pulmonary arterial hypertension (PAH) treatments are limited, with high mortality despite current FDA-approved drugs. Research is ongoing for novel therapies and expanded applications to address this unmet medical need.
Area of Science:
- Cardiovascular Medicine
- Pulmonary Medicine
- Pharmacology
Background:
- Pulmonary arterial hypertension (PAH) involves progressive narrowing of pulmonary arteries, leading to right heart failure.
- Current treatments for PAH have significant limitations, and patient outcomes remain poor.
Purpose of the Study:
- To review current FDA-approved PAH therapies and agents in clinical development.
- To explore novel therapeutic targets and new applications for PAH treatments.
Main Methods:
- Literature search of PubMed for PAH and treatment.
- Inclusion of data from scientific meetings and pharmaceutical websites.
Main Results:
- Overview of current PAH drug classes: prostacyclins, endothelin-receptor antagonists, and PDE-5 inhibitors.
- Identification of new agents in development and emerging therapeutic targets.
- Investigation into expanded uses of PAH therapies for other forms of pulmonary hypertension.
Conclusions:
- Despite 20 years of active research, significant unmet medical needs persist in PAH treatment.
- Continued basic and clinical research is crucial for developing more effective PAH therapies.
