Explains

PharmD, BCPS · Clinical pharmacist Updated

Generic centanafadine is expected to be available between 2037 and 2038. None is for sale yet.

Why 2037 to 2038?

The patent fight is likely to end in an agreement that sets the launch. The terms are not public yet. We rate it probable: more likely than not, but it can still move.

Will the generic cost less?

Usually, but no company is recorded as having applied to make one yet, and a single company usually brings only a modest drop. See the price pattern

What should I do now?

Keep taking Simtriyo as prescribed. When a generic arrives, your pharmacy may switch you to it automatically, and it may look different. What a generic means for you

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

Simtriyo’s Road to a Generic

The first generic of Simtriyo is expected between 2037 and 2038.

Why that month: the patent fight is likely to end in an agreement that sets the launch. The terms are not public yet.

Brand alone on the market Approval date not in the Orange Book
Brand alone on the market First generic expected Swipe the chart sideways to see every year.

The bar shows Simtriyo on the market on its own until the month we expect the first generic (the green band), a month and never a day. Its approval date and patents are not in the FDA Orange Book under this name, so the bar fades in from the left. The expected month comes from court records and company announcements.

Who Is Lined Up to Make Generic Centanafadine

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 company is recorded as having applied to the FDA to make a generic Simtriyo yet.

2

Approved by the FDA

We could not find Simtriyo’s own record in the FDA Orange Book under this name, so the approved generic makers are not shown.

3

For Sale in Pharmacies

Not yet. No company lists a generic centanafadine for sale with the FDA.

Sources: how many companies have applied, from court records and company announcements; approved generics from the FDA Orange Book; what is for sale from the FDA NDC Directory. The FDA does not disclose an application before it approves it (21 CFR 314.430).

Simtriyo 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 Simtriyo, 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 a Generic Simtriyo Means for You

Nothing Changes Until It Is in Pharmacies

Until a generic is actually for sale, keep filling Simtriyo as usual. When one arrives, there is nothing you need to sign up for.

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.

Until a generic is on US pharmacy shelves, be careful with websites that offer “generic Simtriyo”. The FDA warns that unlicensed online pharmacies sell counterfeit and unapproved medicines; its BeSafeRx page shows how to check a pharmacy.

Questions people ask about Simtriyo

Is there a generic for Simtriyo right now?

No. As of October 9, 2026 no generic centanafadine is listed for sale in the FDA NDC Directory.

When will Simtriyo go generic?

2037 to 2038 is the expected window, and that is probable but not certain. The patent fight is likely to end in an agreement that sets the launch. The terms are not public yet.

Will generic centanafadine be the same as Simtriyo?

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. No company is recorded as having applied to the FDA to make one yet, and a single company usually brings only a modest drop.
