FDA List of Authorized Generic Drugs
No. The term “authorized generic” drug is most commonly used to describe an approved brand name drug that is marketed without the brand name on its label. Other than the fact that it does not have the brand name on its label, it is the exact same drug product as the branded product. An authorized generic may be marketed by the brand name drug company, or another company with the brand company’s permission. In some cases, even though it is the same as the brand name product, a company may choose to sell the authorized generic at a lower cost than the brand name drug.
How Is an Authorized Generic Drug Different from what Is Commonly Understood to Be a Generic Drug?
A generic drug, as that term is commonly understood and referred to by health care providers and insurers, is a copy of a brand-name drug that is developed and made by a company other than the company that makes the brand-name drug. A generic drug is the same as the brand-name drug in active ingredient, conditions of use, dosage form, strength, route of administration, and (with certain permissible differences) labeling. However, a generic drug may have certain minor differences from the brand-name product, such as different inactive ingredients. To obtain approval of a generic drug, a company must submit an Abbreviated New Drug Application (ANDA) to FDA and prove that its product is the same as the brand-name drug in the ways described above, and that it is “bioequivalent,” meaning it gets to the part of the body where the drug works at the same time and in the same amount. A generic drug must also meet the same standards of quality and manufacturing as the brand name drug. An ANDA applicant is not required to provide independent evidence of the safety and effectiveness of a proposed generic drug. Instead, the applicant relies on FDA’s finding that a previously approved drug product is safe and effective. Therefore, it is generally less costly to obtain approval of a generic drug than a brand name drug.
An authorized generic drug is the same as the brand-name drug but does not use the brand name on the label. In addition, an authorized generic version of a tablet or capsule may have a different color or marking. Because an authorized generic drug is marketed under the brand name drug’s New Drug Application (NDA), it is not listed in FDA’s Approved Drug Products With Therapeutic Equivalence Evaluations (the Orange Book). An authorized generic is considered to be therapeutically equivalent to its brand-name drug because it is the same drug. This is true even if the brand-name drug is “single source,” meaning there are no ANDAs approved for that product, or coded as non-equivalent (e.g., BN) by FDA in the Orange Book. While a separate NDA is not required for marketing an authorized generic, FDA requires that the NDA holder notify the FDA if it markets an authorized generic. The NDA holder may market both the authorized generic and the brand-name product at the same time.
Listing of Authorized Generic Drugs
As part of their required annual reports, NDA holders must notify the FDA of any authorized generic drugs marketed under their approved NDAs. FDA publishes a list of reported authorized generics and updates that list quarterly.
Statutory History and Legal Definition for Annual Reports
MORE INFO
On September 27, 2007, the President signed into law the Food and Drug Administration Amendments Act (FDAAA) (Public Law 110-85). Among other things, FDAAA added new subsection (t) to section 505 of the Federal Food, Drug, and Cosmetic Act (the Act). Section 505(t) is titled “Database For Authorized Generic Drugs,” and requires that FDA publish a complete list on its Internet site of all authorized generic drugs, including (1) the drug trade name, (2) the brand company manufacturer, and (3) the date the authorized generic drug entered the market. The agency is required to update the list quarterly. Section 505(t)(2) of the Act requires the list to contain authorized generic drugs included in an annual report submitted to the agency after January 1, 1999.
Subsection 505(t)(3) defines an “authorized generic drug” as a listed drug as defined in § 314.3 that has been approved under subsection 505(c) of the act and is marketed, sold, or distributed directly or indirectly to retail class of trade with either labeling, packaging (other than repackaging as the listed drug in blister packs, unit doses, or similar packaging for use in institutions), product code, labeler code, trade name, or trade mark that differs from that of the listed drug.

Generic drug guide
Generic alternatives and generic equivalents to brand-name medications may help patients save money. The U.S. Food and Drug Administration (FDA) states that it ensures the safety and effectiveness of the generic drugs it approves. 1 According to the FDA, a generic drug is identical, or bioequivalent, to a brand-name drug and is “required to have the same active ingredient, strength, dosage form and route of administration as the brand-name product.” 2
A generic alternative is not a direct generic for a particular branded medication, but in most cases it is in the same therapeutic class as the brand. Alternative drugs produce similar clinical outcomes and often have similar side-effect profiles.

Cialis and Viagra are brand-name prescription drugs that can treat erectile dysfunction. Learn how they are work differently to treat ED.
If you are experiencing erectile dysfunction (ED) , there are many options available to help you. Treatment options for ED include medications and non-drug treatments, such as lifestyle changes and talk therapy.

Cialis and Viagra are brand-name prescription drugs that can treat ED.
They are part of a class of medications called phosphodiesterase-5 (PDE5) inhibitors that work by increasing blood flow to the penis. Other similar drugs include Levitra (vardenafil) and Stendra (avanafil). While they can help treat occasional or long-term ED, PDE5 inhibitors will not treat any underlying medical condition that can contribute to ED, such as diabetes or heart disease.\
As always, it’s important to consult a healthcare provider before starting a new medication. Continue reading to learn more about using Cialis or Viagra, their potential side effects, and other information.

It is prescribed to treat erectile dysfunction and benign prostatic hyperplasia (BPH). Cialis can be taken as needed before sexual activity or once daily , with effects lasting up to 36 hours. Cialis reaches maximum levels in the body between 30 minutes and six hours after taking it. It can be taken with food or on an empty stomach.

Cialis can also be taken once daily if you have ED, BPH, or ED and BPH. For ED, Cialis can be taken as 2.5 mg once daily. The maximum dosage for once-daily treatment for ED is 5 mg per day. For BPH alone or BPH and ED, Cialis can be taken as 5 mg at around the same time every day.

Conditions treated by Cialis vs. Viagra
Cialis is primarily used to treat ED. However, it is also approved to treat signs and symptoms of an enlarged prostate, also called benign prostatic hyperplasia (BPH). Tadalafil , the active ingredient in Cialis, is also available as a brand-name drug called Adcirca, which is used to treat pulmonary arterial hypertension (PAH), or high blood pressure in the lungs. Tadalafil can also be used off-label for Raynaud’s phenomenon, a rare blood vessel disorder, and female sexual arousal disorder.
Viagra is only FDA-approved to treat ED. Sildenafil citrate , the active ingredient in Viagra, is also used to treat PAH under the brand name Revatio. Viagra is sometimes used off-label to treat Raynaud’s phenomenon and female sexual arousal disorder.

For instance, Cialis has been shown to help improve ejaculation and the ability to reach an orgasm in men. Viagra may also help men who have problems with early ejaculation by improving ejaculatory control.

Is Cialis or Viagra more effective?
Cialis and Viagra are both effective treatments for erectile dysfunction. Most of the differences between the two drugs have to do with how long their effects last and how they are dosed. Still, clinical trials comparing the drugs have provided some interesting insights.
Although Cialis and Viagra are both effective, Cialis may be preferred for its once-daily dosing. Cialis may also be preferred over Viagra in men who have BPH in addition to ED. Viagra may be preferred for its short half-life in men who are able to plan their sexual encounters or those who only need ED treatment on occasion.
In a meta-analysis pooling 16 different trials and analyzing over 5,000 patients, Cialis and Viagra were found to be similarly effective and safe. Results on effectiveness were based on the International Index of Erectile Function (IIEF)-EF scale, which is widely used to assess erectile function. Both drugs had similar incidences of side effects. However, those taking Cialis experienced improved sexual confidence and preferred it over Viagra for its long-acting effects.
If you experience ED, it’s important to consult a doctor to determine which treatment option may be best for you. One medication may be more effective or preferred over the other, depending on your overall condition.

Common side effects of Cialis and Viagra
Cialis and Viagra share several common side effects, such as headache, indigestion, muscle pain, back pain, and nasal congestion. Other possible side effects of these drugs include abnormal changes in vision, nausea, dizziness, and rash.
Both ED medications can also cause some degree of flushing, which is a warm feeling with a blushed skin tone, especially on the face. Flushing is caused by the vasodilator effects of these drugs, which relaxes smooth muscles in the blood vessels to increase blood flow.
In addition to these side effects, Cialis may also cause diarrhea and some pain in the arms or legs. Viagra may cause more nausea, dizziness, and rash than Cialis.
Serious side effects of Cialis and Viagra include an erection that doesn’t go away (priapism) and sudden loss or decrease in vision or hearing. Other serious side effects may include cardiovascular complications, such as heart attack and stroke, when taken with certain drugs (see Drug Interactions).

Drug interactions of Cialis vs. Viagra
PDE5 inhibitors like Cialis and Viagra have similar drug interactions. The use of Cialis or Viagra should be avoided with certain medications that can decrease blood pressure. These medications include nitrates and guanylate cyclase stimulators. Taking nitrates or guanylate cyclase stimulators, such as riociguat, with Cialis or Viagra can cause dangerously low blood pressure (hypotension).
Combining a PDE5 inhibitor with alpha-blockers, antihypertensives, or alcohol may also lead to hypotension. Very low blood pressure could lead to dizziness, fainting, and an increased risk of heart attack or stroke.
Cialis and Viagra are both processed in the liver. Therefore, they should not be used with medications that alter the function of certain liver enzymes. CYP3A4 inhibitors, such as certain antibiotics, antifungals, and HIV protease inhibitor drugs, can increase the levels and possible side effects of Cialis and Viagra in the body. CYP3A4 inducers, such as certain anticonvulsants and antibiotics, can decrease the levels and overall effectiveness of Cialis and Viagra.
The use of Cialis or Viagra should also be avoided with alcohol and grapefruit juice. Consuming alcohol or grapefruit juice may increase the side effects of ED medications.
