Nevanac vs Prolensa
Introduction
For patients dealing with postoperative inflammation and pain after cataract surgery, certain drugs that inhibit the production of prostaglandins, which are compounds in the body responsible for causing inflammation and pain, can help manage these symptoms. Nevanac (Nepafenac) and Prolensa (Bromfenac) are two such drugs that are prescribed for this purpose. Both medications work by inhibiting cyclooxygenase enzymes involved in prostaglandin production but differ slightly in their chemical structure and formulation. Nevanac is a prodrug converted into its active form inside the eye providing both superficial and intraocular anti-inflammatory activity. On the other hand, Prolensa has a higher concentration allowing once-daily dosing compared to three times daily for Nevanac.

What is Nevanac?
Nepafenac (the generic name for Nevanac) and Bromfenac (the generic name for Prolensa) are both nonsteroidal anti-inflammatory drugs, prescribed predominantly to alleviate pain and inflammation following cataract surgery. They represent a significant advancement from the earlier class of corticosteroid eye drops that were previously used post-operatively.
Nevanac was first approved by the FDA in 2005. It works by inhibiting an enzyme known as cyclooxygenase, thereby reducing the production of prostaglandins — substances responsible for causing pain and inflammation. On the other hand, Prolensa operates on a similar principle but is generally administered only once daily due to its longer duration of action compared to Nevanac which usually requires three times a day administration.
While both have proven their efficacy in managing post-operative discomfort, it's worth noting that they differ slightly in terms of side effects: while common side effects with Nepafenac include decreased visual clarity and feeling like something is in your eye; Bromfenac may cause mild stinging or burning when applied.
What conditions is Nevanac approved to treat?
Nevanac is approved for the treatment of pain and inflammation associated with:
- Cataract surgery
- Postoperative ocular inflammation
It's also used to reduce the risk of macular edema following cataract surgery in diabetic patients.
How does Nevanac help with these illnesses?
Nevanac helps manage post-operative eye inflammation and pain by decreasing the amount of prostaglandins in the eyes. Prostaglandins are compounds that contribute to inflammation, swelling, and pain when produced in large quantities in response to injury or surgery. By blocking an enzyme involved in producing these substances (cyclooxygenase), Nevanac reduces their levels, thereby alleviating associated discomfort after ocular surgery.
Much like serotonin's role as a neurotransmitter affecting mood and cognition, prostaglandins play a crucial part in our body’s inflammatory responses – which include those occurring post-surgery within delicate structures such as the eyes. Consequently, by reducing prostaglandin production via its active ingredient (nepafenac), Nevanac can limit negative effects of post-operative inflammation and help patients manage their condition more comfortably.
What is Prolensa?
Prolensa is a brand name for bromfenac, which is a non-steroidal anti-inflammatory drug (NSAID) that reduces the production of prostaglandins, substances in the body responsible for pain and inflammation. It's often used to reduce swelling and pain in the eye after cataract surgery. Prolensa was first approved by the FDA in 2013. As it's not an antibiotic medication, it doesn't kill bacteria or other microorganisms that can cause infections. Its lack of antimicrobial activity means its side-effect profile differs from antibiotics; specifically, it does not cause antibiotic-associated side effects such as diarrhea or yeast infections (common side effects with some antibiotics). The effect on reducing prostaglandin production can be beneficial particularly post-operative patients experiencing ocular inflammation or pain.
What conditions is Prolensa approved to treat?
Prolensa is a nonsteroidal anti-inflammatory drug (NSAID) eye drop that has received FDA approval for the treatment of:
- Postoperative inflammation and reduction of ocular pain in patients who have undergone cataract surgery
- Anterior chamber inflammation following ophthalmic surgery
Its one-drop-a-day dosage makes it a preferred option for many due to its convenience.
How does Prolensa help with these illnesses?
Prolensa is a non-steroidal anti-inflammatory drug (NSAID) eye drop that reduces inflammation and pain in the eye following cataract surgery, much like Nevanac. However, Prolensa has a higher concentration of bromfenac (0.07% compared to 0.03% in Nevanac), which may make it more effective at reducing inflammation. It works by inhibiting cyclooxygenase, an enzyme involved in prostaglandin production - substances responsible for causing inflammation and pain. Its action on these enzymes can alleviate some symptoms associated with post-operative states, thus providing relief for patients after ophthalmic procedures such as cataract surgery. Because of its potency and less frequent dosing schedule – once daily versus multiple times per day – Prolensa might be preferred when a patient requires potent anti-inflammatory effects or finds it difficult to adhere to multiple-dose regimens.
How effective are both Nevanac and Prolensa?
Both nepafenac (Nevanac) and bromfenac (Prolensa) are non-steroidal anti-inflammatory drugs used in ophthalmology, with their primary function being the reduction of pain and inflammation after cataract surgery. They were approved by the FDA within a few years of each other; Nevanac in 2005 and Prolensa in 2013. Both medications act by inhibiting cyclooxygenase, an enzyme that promotes production of pro-inflammatory compounds known as prostaglandins.
The efficacy of both these drugs has been studied extensively via double-blind clinical trials for postoperative ocular inflammation and pain management following cataract surgery. The findings from these studies indicate comparable effectiveness between Nevanac and Prolensa in reducing symptoms such as eye discomfort, redness, or swelling after surgery.
A review published in 2009 concluded that nepafenac is effective at managing post-surgical ocular pain beginning on the first day of treatment. It also showed favorable safety profiles amongst numerous patients without causing any serious systemic side effects.
On another note, a 2017 systematic review suggested that bromfenac appears to be more effective than placebo when it comes to controlling inflammation following intraocular surgeries including cataracts removals. However, it's often chosen over other NSAIDs because it requires less frequent dosing due to its longer half-life compared to most NSAIDs which can improve patient adherence to therapy.
In summary, while both medications demonstrate similar efficacy profiles for relief from postoperative ocular discomfort or inflammation they do have some differences. For example Prolesa may offer practical advantages like less-frequent dosing schedule while Nevanca might be better tolerated according to some studies but ultimately choice between them would depend upon individual patient factors along with physician’s judgement based on available evidence.

At what dose is Nevanac typically prescribed?
Nevanac and Prolensa are both ophthalmic solutions used for the reduction of pain and inflammation following cataract surgery. Dosages of Nevanac typically consist of one drop into the affected eye three times daily beginning 1 day prior to surgery, continued on the day of surgery, and up to two weeks post-operation. Similarly, Prolensa dosage generally consists of one drop in the surgical eye once a day starting from 1 day before surgery until two weeks after. In either case, it's important not to exceed these recommended dosages without consulting your healthcare provider.
At what dose is Prolensa typically prescribed?
Prolensa treatment is usually initiated one day prior to eye surgery, continued on the day of surgery, and through the first 2 weeks post-surgery. The recommended dosage is one drop into the affected eye once daily. Overdosing should be avoided as more frequent administration may decrease its efficacy by increasing risk for adverse effects. If a dose is missed, it should be administered as soon as possible; however, if it's almost time for the next dose, skip it and continue with your regular dosing schedule. Always consult your doctor or pharmacist before adding any other medication to your regimen while on Prolensa.
What are the most common side effects for Nevanac?
The side effects of Nevanac and Prolensa, both used as anti-inflammatory medications in the management of postoperative pain and inflammation associated with cataract surgery, are typically localized to the eyes. These can include:
- Eye pain or discomfort
- Dry eye symptoms
- Itching or stinging sensation in the eyes
- Tearing (excessive tear production)
- Sensitivity to light
- Vision changes such as blurred vision
- Redness, swelling, or bleeding of the eyelid
- Foreign body sensation in the eye (feeling like there is something stuck in your eye)
These are some common side effects but if you experience severe discomfort or any other unusual reactions after using these drugs it's important to seek medical attention immediately.
Are there any potential serious side effects for Nevanac?
While Nevanac and Prolensa are both non-steroidal anti-inflammatory drugs (NSAIDs) used to reduce pain and inflammation in the eyes, they can sometimes cause different side effects. Here are some rare but severe potential side effects of these medications:
- Any signs of allergic reaction: hives, difficulty breathing, swelling in your face or throat
- Changes in vision: blurred vision, tunnel vision, eye pain or swelling, seeing halos around lights
- Eye sensitivity to light
- Eye discharge
- Slow healing after your eye procedure
- Bleeding from the eye
It's also possible that these medications could affect other parts of the body leading to symptoms such as:
-Irregular heartbeat
-Breathing difficulties/shortness of breath
-Unusual tiredness or weakness
These side effects are extremely rare but if you experience any of them while taking either Nevanac or Prolensa you should seek immediate medical attention.
What are the most common side effects for Prolensa?
Prolensa, an eye drop medication like Nevanac, can also potentially cause several side effects. These may include:
- Temporary blurred vision following application
- Mild eye irritation or discomfort
- Dryness or redness in the eyes
- Sensitivity to light (photophobia)
- Mild headache or dizziness
- Metallic taste shortly after use
These symptoms are usually mild and temporary, but if they persist or worsen, it is important to consult with your healthcare provider.
Are there any potential serious side effects for Prolensa?
While Prolensa is typically safe for use, it is important to be aware of potential severe side effects. These adverse reactions may include:
- Signs of an allergic reaction such as hives, difficulty breathing, swelling in your face or throat
- Severe redness, burning or itching sensation in the eyes
- Increased sensitivity to light
- Vision changes including blurred vision or seeing halos around lights
- Eye pain or discomfort that worsens over time
- Excessive tearing or discharge from the eye
If you experience any of these symptoms while using Prolensa, contact your healthcare provider immediately.
Contraindications for Nevanac and Prolensa?
Both Nevanac and Prolensa, similar to most other nonsteroidal anti-inflammatory drugs (NSAIDs) eye drops, may exacerbate the symptoms of certain ocular conditions. If you notice your condition worsening or experience severe discomfort, swelling or changes in vision after using either medication, seek immediate medical attention.
Neither Nevanac nor Prolensa should be used if you are currently taking anticoagulants or other NSAIDs orally. Always inform your physician about all medications and supplements that you're taking; these can interact negatively with Nevanac and Prolensa causing serious side effects.
Remember that both of these medications have potential side effects such as stinging in the eyes upon instillation, temporary blurred vision, headache among others. Therefore it is crucial to use them strictly under a doctor's supervision.
How much do Nevanac and Prolensa cost?
For the brand name versions of these drugs:
- A 3 ml bottle of Nevanac (1mg/ml) averages around $280, which works out to about $10–20/day depending on your dose.
- The price for a 3 ml bottle of Prolensa (0.07%) is approximately $300, working out to roughly $10–20 per day.
Thus, if you are using more drops per day with Nevanac, then brand-name Prolensa might be less expensive on a per-day treatment basis. However, cost should not be the primary consideration in determining which of these eye drops is right for you.
As it stands now there are no generic alternatives available for either Nevanac or Prolensa. This may change in the future as patents expire and other manufacturers can start producing equivalent medications at potentially lower costs. Always consult with your healthcare provider before making medication choices based solely on cost considerations.
Popularity of Nevanac and Prolensa
Nepafenac, in its generic form as well as brand names like Nevanac, was estimated to have been prescribed to about 1.2 million people in the US in 2020. Nepafenac accounted for around 15% of nonsteroidal anti-inflammatory eye drops prescriptions in the US. However, it appears to be used most commonly for pain and inflammation after cataract surgery, with an increasing trend since its approval by the FDA.
Bromfenac sodium ophthalmic solution, including brand versions such as Prolensa, was prescribed to approximately 900 thousand people in the USA during the same year. In terms of NSAID eye drop prescriptions within the country, bromfenac accounts for nearly 10%. The prevalence of bromfenac has also seen a steady increase over recent years due to its efficacy and once-daily dosing regimen which improves patient compliance.
Conclusion
Both Nevanac (nepafenac) and Prolensa (bromfenac) have proven track records in managing postoperative pain and inflammation associated with cataract surgery. The drugs are both nonsteroidal anti-inflammatory agents that work by inhibiting the cyclooxygenase enzyme, which is involved in the production of prostaglandins, substances that cause inflammation.
Nevanac is a prodrug, meaning it turns into its active form once inside the body, specifically within the eye's tissues. This property allows for a more targeted approach to reducing inflammation. On the other hand, Prolensa does not require this conversion and starts working immediately upon entering ocular tissues.
Both medications are available only as branded products; hence their prices may be significant especially for patients who must pay out of pocket. Moreover, both drugs should be used under medical supervision as they can cause certain side effects such as decreased visual acuity or burning sensation after application.
The safety profile is quite similar between Nevanac and Prolensa. Both drugs are generally well-tolerated but like all medicines they do carry risk of side-effects. Patients using either drug should closely monitor their symptoms and seek immediate medical help if they notice worsening eye redness or discomfort.
