Impact of a Fixed-Dose Combination of Naproxen and Esomeprazole Magnesium on Serum Thromboxane B(2) Inhibition by Low-Dose Aspirin Over 5 Days in Healthy Adults: A Phase I, Randomized, Double-Blind, Placebo-Controlled, Noninferiority Trial. [2011.11.09]
Background: Low-dose aspirin (LDA) and nonsteroidal anti-inflammatory drugs (NSAIDs) are often used concomitantly; however, some NSAIDs may interfere with LDA antiplatelet activity. OBJECTIVE: We evaluated the impact of coadministered enteric-coated naproxen 500 mg and immediate-release esomeprazole magnesium 20 mg (fixed-dose combination) on LDA-mediated platelet cyclooxygenase (COX)-1 inhibition... CONCLUSIONS: This pilot investigation suggests that LDA coadministered with naproxen/esomeprazole magnesium is noninferior to LDA alone for platelet COX-1 inhibition, as measured by serum TXB(2) concentration, in healthy volunteers.

Comparison of the Clinical Efficacy of Naproxen, Associated or Not With Esomeprazol, in Lower Third Molar Removal [Recruiting]
The present clinical trial randomized compared the clinical efficacy of the naproxen

postoperative day were evaluated. For this purpose, 50 healthy volunteers underwent removal

months apart), under local anesthesia with either articaine 4% (1: 200,000 adrenaline) in a
doubleblind, randomized and crossed manner.

Naproxen for the Prevention of HO After Complex Elbow Trauma [Withdrawn]
Complex elbow fractures can lead to formation of new bone (called Heterotopic ossification).
This new bone is unwanted and it can restrict motion. This research study is being done to
learn more about the effect of the drug naproxen, on unwanted formation of new bone around
the elbow as it heals after a fracture. Naproxen belongs to a class of drugs called NSAIDs
which stands for non-steroidal anti-inflammatory drugs.
Several research studies suggest that NSAIDs such as Naproxen can prevent the unwanted
formation of new bone around the hip. The effect of NSAIDS on the formation of bone around
the elbow has not been studied as well as it has been studied for their effect on the hip.
The drug, Naproxen is approved by the US food and drug administration (FDA) for sale but ot
specifically for the treatment of heterotopic ossification.

Naproxen review by 25 year old female patient
|Overall rating:|| || |
|Effectiveness:|| || Highly Effective|
|Side effects:|| || No Side Effects|
|Condition / reason:|| || period cramps|
|Dosage & duration:|| || 500 mg taken 3 days per month for the period of almost 6 years|
|Other conditions:|| || none|
|Other drugs taken:|| || none|
|Benefits:|| || I was able to do normal daily activities again|
|Side effects:|| || I had no side effects.|
|Comments:|| || I always have had really bad cramps. I have tried many different prescription pain killers over the years and none have really made the pain any better. I first started taking Naproxen in 200mg as you can get this over the counter as Aleve in the States. Canada has no such product available. I found that even in 200 mg strength sometimes was enough to make my day bearable. I now get it from my Dr. in 500 mg strength and am able to carry out my normal daily activities as I was unable to even go to work some days before.|
Naproxen review by 16 year old female patient
|Overall rating:|| || |
|Effectiveness:|| || Ineffective|
|Side effects:|| || Moderate Side Effects|
|Condition / reason:|| || Juvenile Idiopathic Arthritis|
|Dosage & duration:|| || 500mg taken twice a day/at 12 hour intervals for the period of Four weeks|
|Other conditions:|| || None|
|Other drugs taken:|| || None|
|Benefits:|| || The treatment did not affect the level of joint pain that I experienced, nor did it improve joint stiffness. I cannot comment on it's effect on inflammation as my inflammation tends not to be visible anyway. This may be the reason that Naproxen did not benefit me|
|Side effects:|| || Caused nausea and stomach pain. The nausea would alleviate a couple of hours before the next dose was due, and start within an hour of the dose. It did not cause actual vomitting, but there were a few occasions on which I felt so nauseous I was convinced I would be sick at any moment. |
|Comments:|| || I would never take Naproxen again without having a LONG discussion with both a doctor and pharmacist.|
Naproxen review by 37 year old female patient

|Side effects:|| || Extremely Severe Side Effects|
|Condition / reason:|| || joint pain|
|Dosage & duration:|| || 500 mg taken 2 in 1 day for the period of 1day|
|Other conditions:|| || only had joint pain before I took this drug|
|Other drugs taken:|| || none|
|Benefits:|| || I didn't feel my joint pain after taking this, I think because I was too bothered by the side effects.|
|Side effects:|| || I had the most intense stomach pain I've ever had in my life. The pain was nearly unbearable. It felt like I had an acid stomach with extreme pain. I drank milk and had taken this will food and still had stomach pain. |
|Comments:|| || I would much ranther have the joint pain, then go through this stomach pain ever again. I've stopped using this and would not recommend it to anyone.|
