Sildenafil is the generic name of an active pharmaceutical ingredient that appears in multiple branded and generic medicine products. Historically prominent U.S. brand identities include Viagra and Revatio, while more recent FDA-approved sildenafil brands include Liqrev and Vybrique.
These brand names do not represent different sildenafil molecules. They identify specific drug products with their own dosage forms, approved indication contexts, labeling and regulatory histories. Two sildenafil brands can therefore share the same active ingredient while differing substantially at the product level.
This page provides a high-level naming map rather than an exhaustive international trade-name directory. The detailed relationships between sildenafil and Viagra or Revatio remain covered on their dedicated pages, while newer brand examples are included here to show why brand identity, formulation and indication should be interpreted separately.
Viagra and Revatio remain two of the best-known sildenafil brand names, but they are no longer the only relevant U.S. proprietary sildenafil identities. FDA-approved products also include Liqrev, an oral suspension associated with a pulmonary arterial hypertension context, and Vybrique, an oral-film product approved for erectile dysfunction.
All of these products use sildenafil as the active drug. What differs is the commercial product identity, dosage form, approved-use context, labeling and regulatory application under which each product is marketed.
Generic sildenafil products add another layer to the naming map. They use the established active-drug name rather than one of these proprietary names, although individual generic products can still have their own manufacturers, formulations, labeling contexts and regulatory records.
| Name | Name Type | Active Ingredient | General U.S. Product Context |
|---|---|---|---|
| Sildenafil | Generic active-drug name | Sildenafil | Appears in multiple branded and generic product contexts |
| Viagra | Brand name | Sildenafil | Erectile dysfunction |
| Revatio | Brand name | Sildenafil | Pulmonary arterial hypertension |
| Liqrev | Brand name | Sildenafil | Pulmonary arterial hypertension |
| Vybrique | Brand name | Sildenafil | Erectile dysfunction |
The term sildenafil identifies the active pharmaceutical ingredient rather than one particular commercial product. This established drug name remains constant even when the medicine appears under different proprietary names or is supplied by different manufacturers.
Generic drug naming allows the active medicine to be identified independently of brand identity. A product labeled simply as sildenafil may therefore share the same active drug with Viagra, Revatio, Liqrev or Vybrique while belonging to a different regulatory product record.
This distinction is especially important because generic sildenafil is not synonymous only with 'generic Viagra.' Generic sildenafil products can exist in different indication and formulation contexts, so the product label remains necessary for understanding exactly what medicine is being supplied.
| Concept | Meaning |
|---|---|
| Generic drug name | Established name of the active ingredient |
| Brand name | Proprietary commercial identity of a specific medicine product |
| Generic product | Approved product identified primarily by the established drug name rather than an originator proprietary name |
Viagra is a branded sildenafil product and remains one of the most widely recognized commercial identities associated with the drug. Its labeling identifies sildenafil citrate as the drug substance context while sildenafil provides the active pharmacological moiety.
In the United States, Viagra is associated with the erectile-dysfunction indication and an oral tablet product framework. That brand identity should therefore be understood as a particular sildenafil product rather than as another name for every sildenafil-containing medicine.
The detailed relationship between the drug and this brand is explained on the sildenafil and Viagra page.
| Feature | Viagra Context |
|---|---|
| Active ingredient | Sildenafil |
| Identity type | Brand product |
| General label context | Erectile dysfunction |
| Dosage-form context | Oral tablets |
Revatio is another major branded sildenafil medicine, but its U.S. regulatory history and indication context differ from Viagra. The shared active drug does not make the two commercial identities interchangeable.
Revatio is associated with pulmonary arterial hypertension and has a broader formulation framework than the classic Viagra tablet context. FDA labeling covers Revatio tablets, powder for oral suspension and injection, illustrating how one brand family can extend across multiple dosage forms.
The dedicated sildenafil and Revatio page explains that brand relationship in greater detail.
| Feature | Revatio Context |
|---|---|
| Active ingredient | Sildenafil |
| Identity type | Brand product |
| General label context | Pulmonary arterial hypertension |
| Formulation framework | Includes tablet, oral suspension and injection contexts |
The current U.S. sildenafil brand landscape is broader than Viagra and Revatio. Liqrev was FDA-approved as a sildenafil oral suspension for pulmonary arterial hypertension in adults, providing an example of a newer proprietary product built around a specific dosage-form and indication context.
Vybrique is a more recent sildenafil brand approved as an oral film for erectile dysfunction. Its existence is particularly useful for understanding why 'sildenafil brand name' and 'sildenafil tablet brand' are not equivalent ideas: a proprietary sildenafil product can use a dosage form that differs from conventional tablets.
These newer products do not change sildenafil's underlying drug identity. Instead, they show how additional proprietary products can enter the market over time while preserving sildenafil as the common active ingredient.
| Brand | Active Drug | Dosage-Form Context | General U.S. Indication Context |
|---|---|---|---|
| Liqrev | Sildenafil | Oral suspension | Pulmonary arterial hypertension |
| Vybrique | Sildenafil | Oral film | Erectile dysfunction |
A single active pharmaceutical ingredient can appear in multiple branded medicine products. Sildenafil illustrates this clearly because several proprietary products share the same active drug while being organized around different formulations, indications and regulatory applications.
The active ingredient determines the core sildenafil pharmacology, whereas the brand identifies a particular commercial and regulatory product. Viagra and Vybrique are both associated with an erectile-dysfunction context, for example, but one is a traditional tablet brand and the other is an oral-film product.
Likewise, Revatio and Liqrev both occupy pulmonary arterial hypertension contexts while differing in product identity and formulation framework. Brand names therefore provide product-level information that cannot be inferred from the active ingredient alone.
| Layer | Shared or Different? |
|---|---|
| Active drug | Shared: sildenafil |
| Brand name | Can differ |
| Approved indication context | Can differ or overlap between brands |
| Product formulation | Can differ |
| Regulatory product identity | Different |
A brand name should not be treated as though it were the generic or chemical identity of the medicine. Sildenafil identifies the drug itself, whereas Viagra, Revatio, Liqrev and Vybrique identify particular proprietary sildenafil products.
This distinction becomes especially important when reading prescribing information or pharmacy records. The word sildenafil tells the reader what active drug is present, while the proprietary name can provide additional clues about the specific product, dosage form and approved-use context.
Separating these identity levels also prevents outdated assumptions. Sildenafil is not simply another word for Viagra, and the existence of several branded sildenafil products means that a brand name cannot be inferred solely from the active ingredient.
| Identity Level | Example |
|---|---|
| Active ingredient | Sildenafil |
| Brand product | Viagra |
| Brand product | Revatio |
| Brand product | Liqrev |
| Brand product | Vybrique |
Brand identity can reflect the indication and regulatory pathway under which a particular product was approved. Sildenafil demonstrates this especially clearly because branded products exist in both erectile-dysfunction and pulmonary arterial hypertension contexts.
The relationship is not simply one brand per indication. Viagra and Vybrique are both associated with erectile dysfunction, while Revatio and Liqrev are associated with pulmonary arterial hypertension in their respective U.S. product contexts.
The broader indication map is covered on the sildenafil uses page. The important naming principle here is that the active ingredient alone does not identify which product label or indication framework applies.
| Brand | Active Drug | General U.S. Indication Context |
|---|---|---|
| Viagra | Sildenafil | Erectile dysfunction |
| Vybrique | Sildenafil | Erectile dysfunction |
| Revatio | Sildenafil | Pulmonary arterial hypertension |
| Liqrev | Sildenafil | Pulmonary arterial hypertension |
Brand products are defined not only by the active drug but also by their dosage form, route, labeling and regulatory application. Sildenafil brand names therefore cannot be interpreted correctly without considering the product format attached to the name.
Viagra is associated with oral tablets, while Vybrique provides an example of sildenafil supplied as an oral film. Revatio spans tablet, oral-suspension and injection contexts, whereas Liqrev is an oral-suspension product.
These examples show why brand and dosage form are separate dimensions of product identity. The full dosage-form overview is available on the sildenafil formulations page.
| Brand | Example Formulation Context |
|---|---|
| Viagra | Oral tablets |
| Vybrique | Oral film |
| Revatio | Tablet, oral suspension and injection |
| Liqrev | Oral suspension |
Generic sildenafil refers to approved drug products identified by the established sildenafil name rather than by a proprietary brand such as Viagra or Revatio. The generic name tells the reader which active drug is present, but it does not by itself specify every product characteristic.
Generic status does not mean the active ingredient is a different drug. Current U.S. records include multiple sildenafil products marketed through abbreviated new drug applications, demonstrating that several manufacturers can supply approved products containing the same active ingredient.
Individual generic products can differ in manufacturer, inactive ingredients, appearance, dosage form, strengths and labeling context while still containing sildenafil as the active drug. The specific product label therefore remains more informative than the word 'generic' alone.
| Feature | Generic Sildenafil |
|---|---|
| Active ingredient | Sildenafil |
| Name basis | Established generic drug name |
| Manufacturer | Can vary |
| Inactive ingredients | Can vary by product |
| Indication or formulation context | Depends on the approved product |
The phrase 'generic Viagra' is commonly used as informal shorthand for generic sildenafil products associated with the erectile-dysfunction market. It is understandable in ordinary conversation, but it is less precise than identifying the actual drug and product.
Sildenafil is the generic drug name and Viagra is one proprietary brand. Because sildenafil also appears in other branded and generic product contexts, the phrase 'generic Viagra' should not be interpreted as a complete description of every generic sildenafil medicine.
Using 'generic sildenafil' together with the relevant product or indication context is therefore more precise when discussing the active ingredient independently of the Viagra brand.
| Phrase | Interpretation |
|---|---|
| Viagra | Specific sildenafil brand product |
| Sildenafil | Generic active-drug name |
| Generic Viagra | Informal phrase generally referring to generic sildenafil in an ED context |
The terms brand name, proprietary name and trade name are used in related ways to describe the commercial identity under which a pharmaceutical product is marketed. They belong to the product-identity layer rather than to the underlying active-drug identity.
The generic or established drug name identifies the active medicine independently of the proprietary product. Sildenafil therefore remains sildenafil whether the product is sold under a brand identity or under generic labeling.
This distinction is more useful than treating every trade name as a separate drug entity. Brand names can change or expand over time, whereas the established active-drug name provides the stable pharmacological reference.
| Term | Typical Meaning |
|---|---|
| Generic name | Established name of the active drug |
| Brand or proprietary name | Commercial identity of a specific medicine product |
| Trade name | Commercially used product name |
Pharmaceutical brand names can vary between markets because regulatory approvals, manufacturers, licensing arrangements and commercial naming strategies differ by country. A proprietary name recognized in the United States therefore should not automatically be treated as the principal sildenafil brand everywhere.
The same active drug can also appear through locally approved generic products or market-specific trade names. Conversely, a brand available in one country may not be approved, marketed or distributed in another.
For that reason, this page focuses primarily on well-established and current U.S. sildenafil identities rather than attempting an exhaustive global directory. For an unfamiliar trade name, the active ingredient and official local product information are more reliable identifiers than the brand name alone.
| Factor | Why Brand Naming Can Vary |
|---|---|
| Country | Drug approvals and marketed proprietary names differ by jurisdiction |
| Manufacturer or license holder | Different companies can market sildenafil products |
| Dosage form | Different proprietary products can be built around different formulations |
| Market history | New sildenafil brand products can be approved over time |
The core molecular mechanism comes from sildenafil rather than from the proprietary name printed on a product. Sildenafil remains a PDE5 inhibitor whether the medicine appears as Viagra, Revatio, Liqrev, Vybrique or an appropriate generic product.
Brand differences can still matter at the product level because formulation, indication, route and labeling can change how a specific product is used and studied. Those distinctions should not be confused with a change in the basic molecular identity of sildenafil.
The plain-language mechanism is explained on the how sildenafil works page.
| Concept | What Determines It? |
|---|---|
| Core PDE5 mechanism | Sildenafil active ingredient |
| Brand identity | Specific proprietary drug product |
| Formulation and route | Specific product design and labeling |
| Approved-use context | Regulatory product label |
A brand identifies a proprietary medicine product or product family, while a formulation describes the physical dosage form in which the drug is supplied. The two concepts often overlap in practical discussion but should not be treated as synonyms.
Current sildenafil brands illustrate both possibilities. Revatio is associated with multiple dosage forms, while Vybrique is specifically an oral-film product and Liqrev is an oral suspension. The active drug remains sildenafil across these different product formats.
Keeping brand and formulation separate makes it easier to understand why sildenafil tablets, oral suspension, oral film and injection are distinct dosage-form contexts even when the pharmacologically active ingredient is the same.
| Concept | Example |
|---|---|
| Active ingredient | Sildenafil |
| Brand | Revatio, Viagra, Liqrev or Vybrique |
| Formulation | Tablet, oral suspension, oral film or injection context |
The phrase sildenafil citrate describes a pharmaceutical salt form, whereas Viagra, Revatio, Liqrev and Vybrique are proprietary product identities. These terms therefore belong to different levels of pharmaceutical description.
A label may refer to sildenafil citrate while expressing the amount of active drug in sildenafil-equivalent terms. That chemical and formulation terminology should not be interpreted as another brand name.
The relationship between sildenafil and its citrate form is explained on the sildenafil citrate page.
| Term | Identity Type |
|---|---|
| Sildenafil | Active drug |
| Sildenafil citrate | Pharmaceutical salt form |
| Viagra / Revatio / Liqrev / Vybrique | Proprietary brand names |
Viagra and Revatio both contain sildenafil, but the shared ingredient does not make the two brand names interchangeable. Each name identifies a separate regulatory product context.
Their indication, dosage-form framework and prescribing information differ. The existence of newer sildenafil brands reinforces the same principle: sildenafil is the common active drug, while each brand name identifies only one part of the broader sildenafil product landscape.
The direct comparison between Viagra and Revatio belongs on the Viagra vs Revatio page rather than being duplicated in this brand map.
| Shared | Different |
|---|---|
| Sildenafil active ingredient | Brand identity |
| Core PDE5-inhibitor pharmacology | Approved-use context |
| Core drug identity | Dosage-form and product labeling framework |
The simplest naming framework starts with sildenafil as the active drug and then asks which specific product contains it. The next layer is the proprietary or generic product identity, followed by formulation, indication and jurisdiction.
In the current U.S. landscape, Viagra and Vybrique provide examples of branded sildenafil products in an erectile-dysfunction context, while Revatio and Liqrev provide branded examples in pulmonary arterial hypertension contexts. Generic sildenafil products sit alongside these brands and should be interpreted according to their own labeling.
Brand names can vary by market and new products can be approved over time. The most reliable way to identify a sildenafil medicine is therefore to read the active ingredient together with the proprietary or generic product name, dosage form and official labeling rather than relying on brand recognition alone.

Major U.S. sildenafil brand identities include Viagra and Revatio, while newer FDA-approved brands include Liqrev and Vybrique. Other trade names may exist in different regulatory markets.
No. Sildenafil is the generic or established name of the active pharmaceutical ingredient. Brand names identify particular proprietary sildenafil products.
Yes. Both contain sildenafil, although their approved-use, formulation and product-label contexts differ.
Liqrev is a branded sildenafil oral suspension approved in the United States for a pulmonary arterial hypertension context, while Vybrique is a branded sildenafil oral film approved for erectile dysfunction.
It is an informal phrase generally referring to generic sildenafil in an erectile-dysfunction context. Sildenafil is the more precise generic drug name, and generic sildenafil products can exist in other product contexts as well.
Yes. Pharmaceutical trade names, manufacturers, approvals and marketed products can vary by country, so an unfamiliar brand should be verified through its active ingredient and official local product information.
