Opsumit® Too Costly? Access Affordable Generic Macitentan Globally for Pulmonary Arterial Hypertension
Share
Summary - This blog shares the latest information as of Jan 2026 on generic Macitentan for pulmonary arterial hypertension. It explains how you can legally access affordable Macitentan globally through MedsPartner, when branded Opsumit® is too expensive or not easily available in your country.
Pulmonary Arterial Hypertension (PAH) is a serious and progressive condition where high pressure in the lung arteries places a constant load on the right side of the heart. This strain can lead to breathlessness, swelling, chest discomfort, and eventual right heart failure if treatment is delayed or interrupted. Opsumit®, whose generic name is Macitentan, is a key medicine in many treatment plans and has proven benefits in slowing disease progression and reducing hospital admissions.
For patients in many countries like the United States, the United Kingdom, and Australia, and many others, the monthly cost of branded Opsumit can easily exceed several thousand dollars, forcing families into very difficult financial choices.
The price of Opsumit® (10 mg) in the US is ~USD 6,335 for 15 tablets without insurance. Through MedsPartner, you can access high-quality generic Macitentan manufactured in India by FDA- or EMA-approved facilities at a fraction of the brand price. For example, generic Macitentan 10 mg from MedsPartner is available at approximately USD 590 for 10 tablets, which offers significant savings to families struggling with treatment costs. When you combine this price difference with legal personal import options in many countries, you get a very real pathway to keep PAH treatment going without destroying your finances.
What is Macitentan (Opsumit®) used for - mechanism of action?
Adults with pulmonary arterial hypertension are treated with macitentan, an endothelin receptor antagonist that lowers lung artery pressure, enhances exercise capacity, and lowers the risk of hospitalisation and disease progression.
In PAH, the body overproduces endothelin - which causes the blood vessels in your lungs to thicken and tighten. Because macitentan inhibits endothelin type A and type B receptors on the walls of those vessels, the lung arteries relax and remain more open, allowing the heart to pump blood more easily. In the large long-term SERAPHIN study - patients who took Macitentan had a lower risk of death or PAH related complications, and many maintained or improved their functional class and six-minute walk distance over several years of follow-up.
How much does Opsumit® cost - why is it so expensive?
Because of its status as an orphan drug, patent protection, and lack of competition, branded Opsumit® can cost several thousand dollars a month in the US and other countries with large economies.
In real life, many patients also face additional pharmacy markups or speciality distribution fees which push the bill even higher.
PAH is a rare disease, which means medicines like Opsumit® receive orphan drug incentives such as extended market exclusivity and lighter competition. Companies also highlight the lengthy and expensive drug development process and the requirement to finance additional research.
Many patients also have to deal with extremely high copayments, stringent eligibility requirements, or outright denials due to local reimbursement criteria in some countries where the national health system or private insurers cover the majority of the costs. For many families, the total cost of travel, meds, monitoring tests, and hospital stays becomes unaffordable.
What are the recent news and updates on Opsumit®?
In August 2025 - Alembic Pharmaceuticals received final approval from the US FDA for generic macitentan tablets. While the commercial launch is still pending, this approval predicts broader availability of lower-cost macitentan in the U.S. and reflects growing global interest in generic options for PAH treatment.
Ongoing research continues to explore the utility of macitentan in different patients. Recent real-world evidence from large registries has demonstrated the effectiveness and safety of the medicine across diverse patient groups, including those with connective-tissue disease-associated PAH.
Can I access affordable generic Macitentan from other countries?
Yes, in many countries you can legally import generic Macitentan for personal use when local options are too costly or unavailable, provided you have a valid prescription and follow your national rules for personal importation.
MedsPartner works with FDA or EMA-approved manufacturers in India to supply generic Macitentan that offers the same ingredient and similar efficacy as Opsumit®. MedsPartner supports compliant personal import by guiding you on the documents your local regulations require, and sourcing from vetted manufacturers after thorough document verification.
Here’s a simple cost comparison -
Branded Opsumit® in the United States, 10 mg, 15 tablets, can cost about USD 6,335 at retail prices without insurance.
Generic Macitentan via MedsPartner, 10 mg, 15 tablets, is currently available for about USD 885 on MedsPartner, with further savings often available for larger quantities.
Patients frequently experience savings of over 85% and, in certain situations, over 90% when compared to paying full branded prices in their home country. MedsPartner has already supported patients in more than 40 countries, which shows that the model works across very different health systems.
What happens when patients turn to MedsPartner for Macitentan?
In mid-2025, a family from Romania contacted MedsPartner after struggling for months with the cost of Opsumit® for a 52-year-old Elena, who had been diagnosed with PAH. Her specialist strongly recommended Macitentan as part of a combination treatment plan, yet local insurance only covered a small share of the price and the remaining copay consumed most of the family's income every month.
After another increase in premiums, Elena and her husband considered stopping treatment altogether because they could not see any other way to manage everyday expenses and also fund her medicine. A wellwisher mentioned the option of personal import of generics from India, and that is how they discovered MedsPartner.
The MedsPartner team reviewed the Romanian rules for personal use imports, explained the documents needed from her doctor and helped the family arrange a supply of generic Macitentan sourced from an FDA-approved manufacturer in India. Within a few weeks, Elena received her first shipment at a price that finally felt manageable.
“It’s not just affordable medicine, it’s mental peace - after a long time”, said Elena’s husband.
Answering your top questions on Macitentan for PAH
Q1. Is generic Macitentan as effective as branded Opsumit® for PAH treatment?
A - Generic Macitentan contains the same active ingredient, strength and dosage as Opsumit®. Regulators require proof of bioequivalence, which means the medicine works in your body in a very similar way to the original brand. When you source generic Macitentan from FDA or EMA-approved manufacturers, you can expect the same clinical effect on lung artery pressure and PAH symptoms as long as you follow your doctor’s plan.
Q2. Is it legal to import generic Macitentan from another country?
A - Many countries allow patients to import a limited quantity of prescription medicines for personal use when they have a valid local prescription and when the product is not affordable or easily available at home. The exact rules differ by jurisdiction, which is why MedsPartner focuses on guidance and helps you understand your local regulations before processing your order.
Q3. What if my insurance denies Opsumit® or my Macitentan copay is too high?
A - Patients across the globe frequently face situations where insurers either deny coverage for Macitentan or place it on a speciality tier, with a very high copay that still leaves families paying thousands every month.
