Brief communication: duration of platelet dysfunction after a 7-day course of Ibuprofen Goldenberg et al. [13] Annals of Internal Medicine 2005 11 healthy adult volunteers received 600 mg ibuprofen orally every eight hours for seven days. Aggregometry showed increased closure time at 40 minutes, with some recovery at eight hours and some recovery at 24 hours
Assessment of common nonsteroidal anti-inflammatory medications by whole blood aggregometry: a clinical evaluation for the perioperative setting Scott et al. [14] World Neurosurgery 2014 12 healthy volunteers received 600 mg ibuprofen three times per day or naproxen 440 mg twice a day for three days. After 24 hours, aggregometry showed no inhibition with ibuprofen while naproxen showed inhibition. At 48 hours, naproxen inhibition recovered in 83% of women and 50% of men. At 72 hours, all platelet function recovered
Dose responses of ibuprofen on platelet aggregation and coagulation in human platelets in vitro Martini et al. [15] Military Medicine 2016 Blood samples collected from four healthy humans were dosed to reach 163 µg/mL ibuprofen or higher, reaching two times, four times, eight times, and sixteen times the initial concentration. Aggregometry showed increased closure time at 163 µg/mL using arachidonic acid activation and at two times concentration using collagen activation
The interaction of ibuprofen and diclofenac with aspirin in healthy volunteers Schuijt et al. [16] British Journal of Pharmacology 2009 12 healthy volunteers received 50 mg diclofenac three times per day or 800 mg ibuprofen two times per day. After 8 hours, TxB2 titers were reduced by 30% with diclofenac and 83% with ibuprofen
Platelet inhibitory effects of OTC doses of naproxen sodium compared with prescription dose naproxen sodium and low-dose aspirin Schiff et al. [17] Current Medical Research and Opinion 2009 48 volunteers received 220 mg two to three times per day versus 550 mg two times per day of naproxen and found similarly reduced (97%+ inhibition) titers of TxB2 compared to 81mg aspirin (98%+ inhibition) 24 hours after the last dose
Effects of celecoxib, a novel cyclooxygenase-2 inhibitor, on platelet function in healthy adults: a randomized, controlled trial Leese et al. [18] Journal of Clinical Pharmacology 2000 24 healthy adults took 500 mg of naproxen twice per day. After 24 hours, both platelet aggregation and TxB2 titers were reduced
Valdecoxib does not impair platelet function Leese et al. [19] American Journal of Emergency Medicine 2002 62 Healthy volunteers were given either 500 mg naproxen or 75 mg diclofenac. After eight hours, aggregometry showed that patients who took diclofenac had normal platelet aggregation and patients who took naproxen had increased closure times. TxB2 titers were also measured at 8 hours and the diclofenac arm showed recovery while the naproxen arm showed significantly decreased measurements
The impact of selective and non-selective non-steroid anti-inflammatory drugs on secondary hemostasis in healthy volunteers Schjerning et al. [20] Thrombosis Research 2009 20 healthy male volunteers received 250 mg naproxen for 21 days. 12 hours after each dose, platelet samples taken from the patients showed inhibition of aggregation
Selective inhibition of COX-2 in humans is associated with less gastrointestinal injury: a comparison of nimesulide and naproxen Shah et al. [21] Gut 2001 36 healthy volunteers received 500 mg naproxen two times per day for 14 days. After one to two hours, TxB2 titers were reduced by 98% with partial recovery two days after the last dose. Platelet aggregation was inhibited with AA but less with ADP activation
Effect of non-selective, non-steroidal anti-inflammatory drugs and cyclo-oxygenase-2 selective inhibitors on the PFA-100 closure time Blaicher et al. [22] Anaesthesia 2004 44 healthy volunteers received 75 mg diclofenac sodium. Aggregometry showed inhibition at three hours with complete recovery at 12 hours
Comparison of the effect of intravenous ketoprofen, ketorolac and diclofenac on platelet function in volunteers Niemi et al. [23] Acta Anesthesiology Scandinavia 1997 10 healthy volunteers were given 1.1 mg/kg diclofenac intravenously. After 2 hours, inhibition was found with adrenaline activation with complete recovery by 24 hours. With ADP activation, no inhibition was found
Propacetamol augments inhibition of platelet function by diclofenac in volunteers Munsterhjelm et al. [24] British Journal of Anesthesia 2003 10 healthy male volunteers received diclofenac intravenously to reach 1.1 mg/kg and found increased closure time at 30 minutes with complete recovery after 22–24 hours
Effect of diclofenac sodium (feloran) on platelet aggregation Tyutyulkova et al. [25] Methods and Findings in Experimental and Clinical Pharmacology 1984 8 healthy volunteers received 25 mg diclofenac three times per day for eight days. 10 hours after the last dose, 25% inhibition was found
Platelet function following administration of a novel formulation of intravenous diclofenac sodium versus active comparators: a randomized, single dose, crossover study in healthy male volunteers Bauer et al. [26] Journal of Clinical Anesthesiology 2010 30 healthy volunteers received diclofenac sodium intravenously (37.5 mg) or diclofenac potassium orally (50 mg). Aggregometry showed inhibition at 1.5 and 3 hours with near-complete recovery after 6 hours for both treatment arms
Indomethacin prevents the long-lasting inhibitory effect of aspirin on human platelet cyclo-oxygenase activity Livio et al. [27] Prostaglandins 1982 3 volunteers received 50 mg indomethacin. After two hours, aggregometry showed inhibition, and TxB2 titers were reduced (99% inhibition) with recovery of both at 48 hours
Time-dependent inhibition of platelet cyclo-oxygenase by indomethacin is slowly reversible Walenga et al. [28] Prostaglandins 1986 4 healthy adults received 25 mg indomethacin. After six hours, inhibition of TxB2 production was found with recovery by 24 hours
Meloxicam, 15 mg/day, spares platelet function in healthy volunteers deMeijer et al. [29] Clinical Pharmacology & Therapeutics 1999 15 healthy volunteers took 25 mg indomethacin three times per day for seven days or 15 mg meloxicam one time per day for seven days. After one hour, aggregometry showed inhibition, and TxB2 titers were reduced (95%+ inhibition).

[33] British Journal of Anesthesiology 2006 18 healthy volunteers received 1 g of acetaminophen intravenously. After 10 minutes, no inhibition of platelet aggregation nor a reduction of TxB2 titers was found. AA activation at 500 µM showed high variability but possible inhibition
Dose-dependent inhibition of platelet function by acetaminophen in healthy volunteers Munsterhjelm et al. [34] Anesthesiology 2005 13 healthy males received acetaminophen intravenously to reach 30 mg/kg. With AA activation, increased closure time was found only at the 10-minute mark with recovering function by 90 minutes. Other activators of platelets found no inhibition
