Market Analysis



For patients who suffer from allergic rhinitis, sinusitis or other types of nasal allergies, certain medications that control the inflammatory response in the body can help stabilize symptoms and manage discomfort. Flonase and Nasacort AQ are two such drugs that are prescribed for these conditions. They each impact different aspects of the immune system's response to allergens but both have anti-inflammatory effects in patients with nasal allergies. Flonase is a corticosteroid known as fluticasone propionate which works by inhibiting multiple cell types like mast cells and eosinophils involved in allergic reactions. On the other hand, Nasacort AQ also a corticosteroid, specifically triamcinolone acetonide, helps reduce inflammation by suppressing migration of polymorphonuclear leukocytes and reversing capillary permeability thus reducing irritation and swelling caused by allergies.

What is Flonase?

Fluticasone (the generic name for Flonase) was the first of its kind in the class of corticosteroid nasal sprays, a significant advancement from previous allergy relief medications. The FDA first approved Fluticasone in 1994. It works by reducing inflammation and swelling in the nasal passages, thereby relieving symptoms like congestion, runny nose, or sneezing typical of allergic rhinitis. On the other hand, Triamcinolone acetonide (Nasacort AQ's active ingredient), another corticosteroid nasal spray introduced later on, functions similarly but has a different chemical structure which grants it slightly varied properties compared to fluticasone propionate. Both drugs target multiple inflammatory substances responsible for allergy symptoms but their efficacy may differ based on individual patient response.

What conditions is Flonase approved to treat?

Flonase and Nasacort AQ are both approved for the treatment of various nasal symptoms:

-Allergic rhinitis, commonly known as hay fever -Nasal congestion caused by allergies -Itchy or runny nose -Sneezing -Nasal discomfort due to colds.

Please note that while they're used to treat similar conditions, these medications have different active ingredients (fluticasone propionate in Flonase and triamcinolone acetonide in Nasacort AQ) which may lead to variations in individual responses and potential side effects.

How does Flonase help with these illnesses?

Flonase helps to manage nasal allergy symptoms by decreasing the number of inflammatory substances in the nasal passages. It does this by acting as a potent glucocorticoid receptor agonist, effectively reducing inflammation and its associated effects such as itching, sneezing, and congestion. Inflammatory substances are produced by our immune system when it encounters an allergen like pollen or dust mites. They play an important role in protecting our body but can also lead to uncomfortable allergic responses. The active ingredient in Flonase is fluticasone propionate which acts directly on these inflammatory processes within the nose. Therefore, Flonase can limit the negative effects of allergies and help patients manage their symptoms more comfortably.

On the other hand, Nasacort AQ contains triamcinolone acetonide which also works by reducing inflammation in your nose providing relief from nasal allergy symptoms such as runny or stuffy nose, sneezing and itching. However each medication may work better for different individuals based on personal response to treatment.

What is Nasacort Aq?

Nasacort AQ is a brand name for triamcinolone acetonide, which is a corticosteroid. It works by reducing inflammation in the nasal passages, thus providing relief from allergic rhinitis symptoms such as sneezing, itching and congestion. Nasacort AQ was first approved by the FDA in 1996 and it's available over the counter. Unlike Flonase (fluticasone propionate), another popular nasal spray that also contains a corticosteroid, Nasacort AQ is alcohol-free, meaning it may be less likely to cause dryness or irritation of the nose and throat. In addition to this characteristic difference, some users report fewer side effects with Nasacort AQ compared to other steroidal sprays including Flonase. Although both are effective at relieving allergy symptoms, one might be preferred over the other based on individual tolerance due to these distinct characteristics.

What conditions is Nasacort Aq approved to treat?

Nasacort AQ is an FDA-approved medication for the management of nasal symptoms associated with:

  • Seasonal allergic rhinitis (hay fever) in adults and pediatric patients aged 2 years and older
  • Perennial allergic rhinitis (year-round allergies) in adult and pediatric patients aged 6 years and older.

How does Nasacort Aq help with these illnesses?

Nasacort AQ, like Flonase, is a corticosteroid that works by affecting the body's immune response to reduce symptoms of allergic reactions. Corticosteroids are hormones naturally produced in the adrenal glands and play an integral role in reducing inflammation and suppressing actions of the immune system. Nasacort AQ operates by diminishing inflammation in nasal passages, which can relieve stuffy or runny nose, sneezing, and itching caused by allergies. Its effects on various elements of immune response may also contribute to its efficacy as a nasal spray for allergy relief. Unlike Flonase which contains fluticasone propionate, Nasacort AQ contains triamcinolone acetonide; both substances work similarly but might have different levels of effectiveness or side-effects depending on individual responses. Therefore it may be prescribed when a patient does not respond well to other typical nasal sprays such as Flonase.

How effective are both Flonase and Nasacort Aq?

Fluticasone propionate (Flonase) and triamcinolone acetonide (Nasacort AQ) are both intranasal corticosteroids with a proven track record of effectiveness in managing allergic rhinitis symptoms. Both were initially approved by the FDA during the 1990s and have since become trusted options for relieving nasal congestion, sneezing, itching, and runny nose associated with allergies.

A direct comparison trial between fluticasone propionate and triamcinolone acetonide showed comparable efficacy in reducing allergy symptoms. Neither medication stood out as significantly superior to the other when it comes to symptom relief or safety profile.

A meta-analysis published in 2004 confirmed that fluticasone propionate is effective from the first day of treatment, has a tolerable side effect profile similar to placebo, and is well-tolerated across diverse patient groups including adults, children, pregnant women, and elderly patients. Fluticasone has also been found to be beneficial beyond just controlling allergy symptoms; studies indicate that regular use can reduce instances of sinusitis related to allergies.

Triamcinolone acetonide was shown in a 2016 review/meta-analysis study to be more effective than placebo at managing allergic rhinitis symptoms while remaining safe for long-term use. Though nasacort may not always be considered as a first-line treatment due its slightly higher incidence of minor side effects like nasal irritation compared to some alternatives like azelastine or mometasone furoate monohydrate (Nasonex), it remains an important part of many people's regimen for controlling allergy symptoms effectively.

At what dose is Flonase typically prescribed?

The recommended dosage of Flonase for adults and children aged 12 years and over is two sprays (50 mcg/spray) in each nostril once daily, totaling 200 mcg. For some patients, a lower dose of one spray per nostril daily may be effective. Children between the ages of 4-11 should use one spray in each nostril per day under adult supervision. On the other hand, Nasacort AQ's suggested usage for adults and adolescents above 12 years is two sprays in each nostril once a day initially which can later be reduced to one spray if controlled conditions are achieved. Kids between ages 2 to 5 should take one spray in each nostril with maximum dosage not exceeding this limit.

At what dose is Nasacort Aq typically prescribed?

Nasacort AQ treatment typically begins with a dosage of 55 mcg per nostril once daily. The dose can then be increased to 110 mcg (2 sprays in each nostril) per day, divided into two doses, spaced at least 8 hours apart. If no response or inadequate relief from symptoms is achieved after a few weeks, the maximum recommended dose is 220 mcg/day divided into four sprays in each nostril and spaced approximately 6 hours apart. As always, it's essential to follow your healthcare provider’s instructions when using this medication.

Popularity of Flonase and Nasacort Aq

Fluticasone, known by the brand name Flonase among others, is a steroid nasal spray intended to relieve symptoms of allergic rhinitis. In 2020, it was estimated that about 4.2 million people in the US were prescribed this medication. Accounting for roughly 10% of intranasal corticosteroid prescriptions in the US, Flonase has seen a general increase in prevalence since its approval by FDA for over-the-counter use in 2014.

Triamcinolone acetonide nasal spray, better known by its brand name Nasacort AQ, was prescribed to approximately 1.8 million people in the USA during the same year. This represents about 5% of all intranasal corticosteroid prescriptions within that period. Unlike Flonase which contains fluticasone propionate as an active ingredient and is used once daily; Nasacort AQ contains triamcinolone acetonide and might be used up to twice daily depending on severity of symptoms. Both medications have similar efficacy profiles but individual patient response may vary.


Both Flonase (fluticasone) and Nasacort AQ (triamcinolone acetonide) are corticosteroid nasal sprays commonly used for the relief of seasonal or perennial allergic rhinitis symptoms. They function by reducing inflammation in the nasal passages, providing relief from common allergy symptoms such as sneezing, runny nose, itchy or watery eyes, and congestion. Both drugs have a long-standing record of usage with numerous clinical studies indicating their effectiveness.

While both medications serve similar purposes, they do differ slightly in their specific mechanisms of action due to differing active ingredients. This may lead to one being more effective than the other for certain individuals based on personal response variations.

Flonase and Nasacort AQ are available over-the-counter which represents significant convenience and cost savings especially for patients who must pay out of pocket. As with many treatments though, these drugs may require an adjustment period where full effects might not be noticeable immediately.

The side effect profiles between Flonase and Nasacort AQ are generally comparable; typical side effects include headache, dryness or irritation within the nose or throat etc., but serious side effects are rare. As always when starting new treatment regimens patients should monitor their responses closely and seek medical help if adverse reactions develop.
