The listed products primarily fall under Pulmonary Arterial Hypertension (PAH) medicines, along with one cardiac medicine, and are used to manage conditions related to high blood pressure in the lungs and heart function. PAH medicines such as Bosentas, Endobloc, Opsutan, Pulmonext, Macitent, and Selepag work by relaxing and widening the blood vessels in the lungs, reducing pulmonary pressure, and improving blood flow, which helps decrease symptoms like shortness of breath and fatigue. These medications often belong to classes like endothelin receptor antagonists, phosphodiesterase-5 inhibitors, and prostacyclin pathway agents, forming an essential part of long-term PAH management. Additionally, Dobutrex is a cardiac medicine commonly used to improve heart pumping function in cases of heart failure or cardiac stress. All these medicines are prescribed under strict medical supervision and play a crucial role in improving patient quality of life and disease control.
