Multiple electrode aggregometry and ADP-receptors. Adding ASA (acetylsalicylic acid) reagent to a blood sample reduces the aggregation responses in ASPItest and COLtest. ASA irreversibly inhibits COX1 in platelets, thereby inhibiting the production of TXA2. The ASA Reagent is used as a quality control in the platelet function testing with Multiplate, allowing the assessment of abnormal platelet responses in ASPItest and COLtest. This reagent is used as a quality control in Multiplate platelet function testing. The GPIIb/IIIa antagonist blocks the binding of fibrinogen to the GPIIb/IIIa receptors, preventing the formation of platelet-fibrinogen bonds and resulting in significantly reduced platelet aggregation in response to all
4-Aminosalicylic acid tuberculosis. Like many commercially significant compounds, PAS has many names including "para"-aminosalicylic acid, "p"-aminosalicylic acid, 4-ASA, and simply P. 4-Aminosalicylic acid 4-Aminosalicylic acid, also known as "para"-aminosalicylic acid (PAS) is an antibiotic primarily used to treat tuberculosis. Specifically it is used to treat active drug resistant tuberculosis together with other antituberculosis medications. It has also been used as a second line agent to sulfasalazine in people with inflammatory bowel disease such as ulcerative colitis and Crohn's disease. It is typically taken by mouth. Common side effects include nausea, abdominal pain, and diarrhea. Other side effects may include liver inflammation and
