Pulmonary hypertension medication list by drug class: Free PDF

Avatar photo Monika Lazarevska
Last Updated: September 21, 2026

A pulmonary hypertension medication list gives clinicians one place to check every FDA-approved PAH therapy, its route, and what needs monitoring. Six drug classes act on three biological pathways, and a seventh agent works outside all of them. One rule drives most decisions.

Class matters more than brand, because escalation means adding a pathway you have not yet targeted. Get that mapping wrong and a patient stays on two drugs that hit the same receptor. What follows is the full drug table, WHO functional class guidance, monitoring rules, and a reference sheet you can download.

Key takeaways

Key takeaways

Six drug classes target the endothelin, nitric oxide, and prostacyclin pathways, and sotatercept works outside all three.

WHO functional class sets the starting regimen, so record it at diagnosis and at every follow-up.

Most newly diagnosed patients begin on dual or triple therapy rather than a single agent.

Bosentan is the only endothelin receptor antagonist that still needs monthly liver function tests.

Riociguat is never combined with a PDE-5 inhibitor or a nitrate, because blood pressure drops sharply.

Three pathways explain every drug on the list

Pulmonary arterial hypertension is treated by widening the pulmonary arteries and slowing the vessel remodeling behind the pressure. Three pathways do that work. The endothelin pathway drives vasoconstriction and fibrosis.

The nitric oxide and sGC pathway widens vessels and holds back cell proliferation. The prostacyclin pathway also widens vessels and damps down platelet activity. Almost every approved drug acts on one of those three.

So a reference that lists brand names alphabetically is hard to use at the bedside. Grouping by pathway shows you what a patient already has covered, and which column is still open. The map below sets each class against the pathway it targets.

Escalation means adding a column you have not covered yet, which is why the pathway view beats an alphabetical drug list. Grouping follows the FDA-approved labeling summarized in the table below.

Other groupings exist. Stanford’s Pulmonary Hypertension Program sorts approved therapies into vasodilator and antiproliferative agents, calcium channel blockers, and supportive treatments. Keeping those details in the patient’s medical records beats a loose printout that only one person updates.

Every FDA-approved PAH medication, grouped by class

Each row below carries the generic and brand name, the route, and the monitoring point that decides whether the drug is safe to continue. Six classes make up the core of targeted therapy. Two further entries sit alongside them.

Drug class Generic (brand) Route Key monitoring
Endothelin receptor antagonists Bosentan (Tracleer) Oral Monthly liver function tests, REMS for hepatotoxicity and pregnancy risk
Ambrisentan (Letairis) Oral REMS for pregnancy risk, monthly pregnancy testing
Macitentan (Opsumit) Oral REMS for pregnancy risk, no mandated monthly LFTs
PDE-5 inhibitors Sildenafil (Revatio) Oral, IV Systemic hypotension, vision changes
Tadalafil (Adcirca) Oral Blood pressure, contraindicated with nitrates
Soluble guanylate cyclase stimulator Riociguat (Adempas) Oral Never with a PDE-5 inhibitor or a nitrate
Prostacyclin analogues Epoprostenol (Flolan, Veletri) IV infusion Continuous pump operation, line infections
Treprostinil (Remodulin, Tyvaso) Subcutaneous, inhaled, oral Infusion site reactions, jaw pain
Iloprost (Ventavis) Inhaled Cough, throat irritation
IP receptor agonist Selexipag (Uptravi) Oral Headache, jaw pain, fluid retention
Calcium channel blockers Nifedipine, diltiazem Oral Only after a positive vasoreactivity test; blood pressure and edema
Fixed-dose combination Macitentan and tadalafil (Opsynvi) Oral Same REMS as macitentan, plus blood pressure
Activin signaling inhibitor Sotatercept (Winrevair) Subcutaneous, every 3 weeks Hemoglobin and platelets before each of the first 5 doses

Opsynvi, approved in March 2024, puts macitentan and tadalafil in a single daily tablet. It suits patients already heading for that pairing, and it removes one pill from the regimen. Sotatercept (Winrevair) arrived the same month with a mechanism none of the older classes share.

WHO functional class sets the starting regimen

Functional class is what you record first, and what you recheck first. The 2022 ESC/ERS pulmonary hypertension guidelines build their treatment algorithm around it. Functional class feeds a formal risk assessment, which is then repeated at every follow-up.

WHO FC Clinical symptoms Recommended initial strategy
I No dyspnea with ordinary activity Observation, or monotherapy where treatment is indicated
II Mild exertional dyspnea and fatigue with ordinary activity Upfront dual therapy, usually an ERA plus a PDE-5 inhibitor
III Marked exertional dyspnea, unable to perform usual activities Dual therapy, moving to triple therapy when risk assessment is high
IV Dyspnea or syncope at rest, unable to perform any activity Triple therapy including an IV or subcutaneous prostacyclin

Read the table as a starting point, not a rule. A patient in class III with comorbidities may be managed differently from a young patient with idiopathic disease. What stays constant is the habit of writing the class down at every visit.

Combination therapy is now the default at diagnosis

Sequential monotherapy has largely gone. Targeting two or three pathways at once produces faster hemodynamic improvement and fewer episodes of clinical worsening.

The ESC/ERS guidelines recommend starting most newly diagnosed patients on a combination rather than a single agent. Approved pairings include:

  • Bosentan (ERA) with sildenafil (PDE-5 inhibitor)
  • Ambrisentan (ERA) with tadalafil (PDE-5 inhibitor)
  • Macitentan (ERA) with tadalafil (PDE-5 inhibitor), also sold as the single tablet Opsynvi
  • Riociguat (sGC stimulator) alone, or alongside a prostacyclin
  • Triple therapy: an ERA, a PDE-5 inhibitor, and a prostacyclin or IP agonist

One combination is never allowed. Riociguat and a PDE-5 inhibitor both act on the nitric oxide pathway, and together they cause severe hypotension and syncope. The same warning applies to riociguat with any nitrate.

What each drug class needs you to monitor

Bosentan is the only endothelin receptor antagonist that still requires monthly liver function tests. The FDA removed that requirement for ambrisentan in 2011, and it was never mandated for macitentan.

All three remain under a REMS for teratogenicity, so patients who can conceive need contraception counseling and monthly pregnancy tests.

PDE-5 inhibitors need blood pressure checks, and sildenafil adds a question about vision changes. Continuous prostacyclin infusions need daily pump management and a look at the infusion site. A line infection is the complication that puts these patients in the hospital.

Sotatercept is dosed subcutaneously every three weeks. Its FDA label asks for hemoglobin and platelet counts before each of the first five doses, then periodically after that. Erythrocytosis and thrombocytopenia are the reasons those counts matter.

Turning that into practice is a scheduling job. Setting the interval once per drug class in your workflow automation means the lab, the pregnancy test, or the follow-up echo gets chased on time.

How to work the reference into a PAH visit

The sheet earns its keep when it drives the consultation rather than sitting in a folder. Five steps cover a typical visit:

  1. Record the baseline. At diagnosis, note WHO functional class and every current medication, diuretics and anticoagulants included.
  2. Map the pathways. Mark which of the three pathways each drug already covers. The open column is your escalation candidate.
  3. Plan the combination. Decide whether the patient needs monotherapy, dual therapy, or triple therapy, then choose the classes to combine.
  4. Set the monitoring. Write down baseline labs, blood pressure, echocardiography, and catheterization dates, with the review interval for each drug.
  5. Track the escalation. At each follow-up, usually four to twelve weeks after a dose change, reassess functional class, hemodynamics, and side effects.

Supportive drugs, and what is coming next

Targeted therapy is only part of the regimen. Diuretics manage fluid overload from right heart failure. Anticoagulants are used in selected patients to reduce thrombosis risk. Supplemental oxygen corrects hypoxia, and digoxin is sometimes added for right ventricular support.

Sotatercept is the newest addition and the first activin signaling inhibitor approved for PAH. It is given as a subcutaneous injection every three weeks, on top of background therapy. It was studied in patients whose response to standard combination therapy was inadequate.

Where a pulmonary hypertension medication list goes wrong

A stale list is worse than no list, because the next clinician trusts it. Four failures turn up again and again in practice:

  • The record holds brand names only, so nobody can see which pathway is already covered.
  • A drug stopped for side effects stays on the list, because the change was noted in free text.
  • REMS dates and pregnancy test results live in a separate spreadsheet that one nurse maintains.
  • A route change goes unrecorded, so a patient moved to inhaled treprostinil still reads as subcutaneous.

Asking for the medication history on pre-visit intake forms catches what a rushed verbal review misses. Patients list what they actually take, which is not always what was prescribed.

Before you close a PAH consultation, check five boxes:

  • Functional class recorded today, not carried over
  • Every targeted agent listed with its class and route
  • Pathways covered, and the one still open, written down
  • Next monitoring date set, with the parameter named
  • REMS and contraception status current for anyone who can conceive

If you also track each administered dose, the medication log template sits alongside this reference and covers that job.

Who should keep this reference to hand

Cardiologists, pulmonologists, internists, and cardiac nurses use it most. It also helps practice managers who build documentation standards for a group, and pharmacists checking a regimen against the approved routes.

A shared format pays off at audit too, because compliance documentation has to show the monitoring actually happened. One agreed layout across the team makes that far easier to evidence.

How Pabau keeps a PAH medication record current

Most practices keep the PAH medication list in two places. The EMR carries the prescription, while a spreadsheet or printout carries functional class, REMS dates, and the monitoring schedule. Within a few months the two versions disagree.

Pabau holds all of that on one patient record. Intake forms collect the current medication history before the appointment. Custom fields hold WHO functional class and the pathways already covered, so the next clinician sees them without opening a second system.

Automated reminders then run the monitoring calendar. You set the interval once per drug class, and Pabau chases the lab, the pregnancy test, or the follow-up echo when it falls due. The schedule no longer rests on one person’s memory.

Keep every PAH medication record current

Pabau holds medication history, WHO functional class, and monitoring dates on one patient record, then schedules the labs and reviews each drug class needs. Your team stops reconciling a spreadsheet against the chart.

Conclusion

Assembling the list is the easy part. Keeping it accurate between visits is the work, because doses change over the phone and patients stop drugs they cannot tolerate.

Print the reference sheet, agree who updates the record after each contact, and name the monitoring parameter beside every date. A regimen documented by pathway is far easier to escalate safely when functional class slips.

Frequently asked questions

Can pulmonary hypertension be cured with medication?

No. Approved therapies improve symptoms, exercise capacity, and hemodynamics, but none reverses the underlying disease. The goal is to slow progression, delay right heart failure, and keep patients out of the hospital. Early diagnosis and prompt escalation matter more to survival than the choice of first agent.

Do the same drugs work for group 2 and group 3 pulmonary hypertension?

No. The drugs listed here are approved for group 1 pulmonary arterial hypertension. In group 2 disease, caused by left heart failure, targeted therapy can worsen pulmonary edema. Group 3 disease is driven by lung disease or hypoxia, so treatment targets the underlying condition and oxygenation. Inhaled treprostinil is the exception, approved for group 3 PH linked to interstitial lung disease.

Are PAH medications safe during pregnancy?

No. Pregnancy carries a high maternal mortality risk in PAH, and endothelin receptor antagonists are teratogenic. That risk is exactly what the REMS programs for bosentan, ambrisentan, macitentan, and Opsynvi exist to prevent. Patients who can conceive need reliable contraception and monthly pregnancy testing while on these drugs.

What happens if a patient misses a dose of an infused prostacyclin?

Treat it as urgent. Continuous IV and subcutaneous prostacyclins have very short half-lives, so an interruption can trigger rebound pulmonary hypertension within hours. Patients should carry a backup pump, spare cassettes, and their PAH center’s 24-hour number. Any pump alarm or line problem needs a call the same day.
