Explains

PharmD, BCPS · Clinical pharmacist

It already is. A generic bimatoprost is listed for sale by 15 companies, so ask your pharmacy whether it can fill your prescription with one.

Why 2041?

No generic application is on record yet. The month follows the patents and protections on record, which a challenge or a deal can end early. We rate it probable: more likely than not, but it can still move.

What should I do now?

Ask your pharmacy whether it can fill your prescription with a generic. It may look different from Durysta, but the active ingredient, strength and form are the same. What a generic means for you

Our month is only an estimate based on available information, so we never name a day.

Durysta’s Road to a Generic

Durysta has had the market to itself since the FDA approved it in March 2020 (Abbvie Inc). Its 7 listed patents run to October 2034.

The first generic of Durysta is expected sometime in 2041.

No generic application is on record yet. The month follows the patents and protections on record, which a challenge or a deal can end early.

Each bar runs from the brand’s approval to the day that protection ends. The green band is our projection for the first generic: a month, never a day, because legal dates move and a generic reaches shelves days to weeks after it is allowed.

Durysta Patents and FDA Protections

Every patent and exclusivity the FDA Orange Book lists for Durysta’s own applications. A protection running past the expected month does not mean the date is wrong: a settlement or a court ruling can let a generic in before a patent ends, and a patent on one formulation or use does not block every generic.

Who Is Lined Up to Make Generic Bimatoprost

Three steps stand between a brand and a generic you can buy: a company applies to the FDA, the FDA approves it, and the company starts selling it.

1

Applied to the FDA

No application count is on record for Durysta, but the FDA has already approved 9 companies (step 2), and every approval starts with an application.

The FDA has tentatively approved 5 companies’ generics, listed below. A tentative approval means the generic is ready, but a patent or exclusivity still stops the FDA from giving it final approval.

2

Approved by the FDA

The FDA has approved generic versions from 9 companies, the first in February 2015. Approved is not the same as on sale: patents, a settlement or the company’s own plans can still hold a launch.

3

For Sale in Pharmacies

Yes. A generic bimatoprost is listed for sale by 15 companies. Ask your pharmacy whether it can fill your prescription with it.

Durysta Price: What Pharmacies Pay and What Generics Usually Do

What a Generic Could Cost

How we estimate it. The national survey of what pharmacies pay (NADAC) has no recent price for Durysta, so we cannot show dollars. Here is the FDA’s finding of how far the price pharmacies pay usually falls as generic companies join: about 31% with one company, 44% with two, 73% with four and over 95% with six or more (the typical drop for every drug whose first generic came out from 2015 to 2017).

Median prices pharmacies paid for the generic (invoice prices), compared with the brand’s price before generic entry, from FDA’s 2019 analysis “Generic Competition and Drug Prices”. At the manufacturer’s price FDA found steeper drops (about 39%, 54%, 79% and over 95%), the figures quoted elsewhere on this tracker. A typical pattern, not a price quote for this medicine.

What Medicare and Medicaid Spend on Durysta

Big public spending is part of why generic makers line up for a medicine, and why its first generic matters beyond the pharmacy counter. Figures are before manufacturer rebates, which are confidential.

What a Generic Durysta Means for You

Nothing Changes Until It Is in Pharmacies

A generic is listed for sale now, so your pharmacy may already be able to fill your prescription with it.

Your Pharmacy May Switch You Automatically

Every state lets pharmacists fill a brand-name prescription with an FDA-approved generic rated as equivalent to it, and about 19 states require them to, unless your prescriber writes “dispense as written” or “brand medically necessary” on the prescription. Some states ask the pharmacist to tell you, or to get your OK first. A study of every state’s law has the details.

It Will Probably Look Different

US trademark law does not let a generic look exactly like the brand, so the color, shape or markings usually change. The active ingredient, strength and form are the same. An “authorized generic,” made by or for the brand’s own company, can look identical. The FDA explains.

Your Insurance May Change Too

Once a lower-cost version is available, many insurance plans charge more for the brand, or stop covering it. Your plan’s drug list (formulary) says how.

Questions people ask about Durysta

Is there a generic for Durysta right now?

Yes. The FDA NDC Directory lists a generic bimatoprost from 15 companies. Ask your pharmacy whether it can fill your prescription with it.

When will Durysta go generic?

It already has. The FDA NDC Directory lists a generic bimatoprost from 15 companies, so ask your pharmacy whether it can fill your prescription with one.

Will generic bimatoprost be the same as Durysta?

Yes in the ways that matter: the same active ingredient, strength and form, with proof that it reaches your blood the same way. Inactive ingredients can differ, which is why some people notice a different look or taste.

How much will the generic cost?

Nobody can say for sure before launch. The FDA has already approved 9 companies to make a generic, and how many of them launch decides how far the price falls.

Has the FDA approved a generic Durysta?

Yes. The FDA Orange Book lists approved generic versions from 9 companies, the first approved in February 2015: Sandoz Inc, Apotex Inc, Gland Pharma Ltd, Alembic Pharmaceuticals Ltd and 5 more. Approved is not the same as on sale: patents, a settlement or the company’s own plans can still hold a launch.

When does the Durysta patent expire?

The FDA Orange Book lists 7 patents for Durysta; the last runs to October 2034. A patent date is not the launch date: settlements and court rulings often bring a generic earlier, and FDA approval or a company’s own plans can make it later. The expected window on this page (Sometime in 2041) weighs all of that.
