Description
Curator's Comment: description was created based on several sources, including https://www.drugs.com/international/triflusal.html | https://www.drugbank.ca/drugs/DB08814 | https://www.ncbi.nlm.nih.gov/pubmed/19465361 | https://www.ncbi.nlm.nih.gov/pubmed/19641312

Triflusal (trade names Disgren, Grendis, Aflen, Triflux, ets) is a member of the salicylate family with a well-established platelet aggregation inhibitory profile that differs from that of acetylsalicylic acid (ASA) in its pharmacokinetic and pharmacodynamic properties. Triflusal irreversibly inhibits cyclooxygenase-1 through its potency is lower than that of acetylsalicylic acid (ASA). Triflusal shows potent inhibition of vascular prostacyclin synthesis, and weak inhibition of platelet phosphodiesterase. Triflusal also favors the production of NO and increases the concentration of cyclic nucleotides. A number of experimental and clinical studies have shown that triflusal is a potentially useful choice in the treatment and prophylaxis of brain ischemia because of its antithrombogenic as well as neuroprotective effects. Triflusal anti-thrombogenic properties have been demonstrated clinically and experimentally, while its neuroprotective effects have been shown only in animal models. Triflusal is administered orally. It Is absorbed primarily in the small intestines and its bioavailability in humans ranges from 83% to 100%. Once absorbed, 99% of triflusal binds to plasma proteins in experimental animals as well as in humans. Triflusal readily crosses organic barriers, but its blood levels are always higher than tissue levels. Upon passage through the liver, triflusal is deacetylated, forming 2-hydroxy-4-trifluoro-methyl-benzoicacid (HTB) as the main active metabolite. Triflusal inhibits platelet aggregation and interaction of platelets with subendothelium. The antiplatelet effect of triflusal has been documented in experimental animals and in humans, in in vitro and ex vivo studies, and in in vivo models of thrombogenesis in animals. Triflusal inhibited collagen- or arachidonic acid-induced platelet aggregation in platelet-rich plasma more effectively than ADP-induced platelet aggregation. Independently of its antithrombotic effect, triflusal acts directly on the nervous tissue to reduce the damage caused by ischemic or cytotoxic insults. The daily oral intake of 600 mg triflusal led to HTB levels in the cerebrospinal fluid that had neuroprotective effects in experimental animals. Traditionally, antiplatelet drugs have been associated with an increased risk of bleeding complications.

Sample Use Guides

The recommended dosage in adults is 600-900 mg/day, administered as a single dose of 600 mg or in two or three doses of 300 mg, preferably during or after meals.
Route of Administration: Oral
In Vitro Use Guide
Platelet rich plasma (500 mkL) was incubated at 37C for 3 min in the aggregometer with continuous stirring (1000 rpm) and then stimulated with submaximal concentrations . of thrombin (0.025 U/ml) or ADP (1 mkM). Before stimulation, 100 mkl of the neutrophil suspension was added to plasma rich plasma to reach a final amount of 1.25x10^8 platelets and 1x10^6 neutrophils (125:1) which approximate the relative concentrations in normal blood. In other series of experiments, increasing neutrophil concentrations ranging from 10^6 to 10^7 cells/ml were added to 1.25x10^8 platelets. Acetylsalicylic acid or triflusal were added to the platelet–neutrophil suspension 5 min before platelet stimulation with thrombin or ADP
