Antiplatelet drugs effect may be affected by patient's medications, current medical conditions, food and supplements taken. Antiplatelet drugs effect may be increased or decreased. An increase in antiplatelet effect would increase the risk of bleeding and could cause prolonged or excessive bleeding.
This effect is mediated by the irreversible blockage of COX-1 in platelets, since mature platelets don't express COX-2. [ 14 ] This antiplatelet property makes aspirin useful for reducing the incidence of heart attacks; [ 13 ] heart attacks are primarily caused by blood clots, and their reduction with the introduction of small amounts of ...
COX-2 is an enzyme facultatively expressed in inflammation, and it is inhibition of COX-2 that produces the desirable effects of NSAIDs. [125] When nonselective COX-1/COX-2 inhibitors (such as aspirin, ibuprofen, and naproxen) lower stomach prostaglandin levels, ulcers of the stomach or duodenum and internal bleeding can result. [126]
Platelets are small blood components that form a plug in the blood vessel wall that stops bleeding. Platelets also produce a variety of substances that stimulate the production of a blood clot. One of the most common causes of increased bleeding risk is exposure to nonsteroidal anti-inflammatory drugs (NSAIDs). The prototype for these drugs is ...
This makes aspirin different from other NSAIDs (such as diclofenac and ibuprofen), which are reversible inhibitors. Low-dose aspirin use irreversibly blocks the formation of thromboxane A 2 in platelets, producing an inhibitory effect on platelet aggregation during the lifetime of the affected platelet (8–9 days). This antithrombotic property ...
Prostaglandin inhibitors are drugs that inhibit the synthesis of prostaglandin in human body. [1] There are various types of prostaglandins responsible for different physiological reactions such as maintaining the blood flow in stomach and kidney, regulating the contraction of involuntary muscles and blood vessels, and act as a mediator of inflammation and pain.
In whole, the NSAIDs prevent the prostaglandins from ever being synthesized, reducing or eliminating the inflammation and resulting pain. [citation needed] Some common examples of NSAIDs are aspirin, ibuprofen, and naproxen. The newer specific COX-inhibitors are not classified together with the traditional NSAIDs, even though they presumably ...
Cardiovascular agents are drugs that affect the rate and intensity of cardiac contraction, blood vessel diameters, blood volume, blood clotting and blood cholesterol levels. [1] They are indicated to treat diseases related to the heart or the vascular system (blood vessels), such as hypertension , hyperlipidemia , coagulation disorders , heart ...
