Chewable aspirin is absorbed faster and is more effective than regular aspirin that is either swallowed whole or chewed and then swallowed, a new study shows. This “seemingly quite simple finding” could lead to improvements in the care of heart attack patients, researchers say.

Sean Nordt, MD, of the University of California, San Diego, and colleagues, gave three different types of aspirin to 14 people between ages of 20 and 61. One group was given regular solid aspirin tablets and told to swallow the pills whole. Another was given regular aspirin tablets and told to chew the pills before swallowing. A third group was given chewable aspirin tablets, and swallowing occurred during chewing.

The researchers then measured levels of aspirin in the blood; researchers say the chewable aspirin consistently showed the greatest and fastest absorption rates. The findings are being presented at the annual meeting of the Society for Academic Medicine in New Orleans. Researchers say the study was done because current guidelines recommend chewing to increase absorption, but evidence that that’s best is scant.

Thirteen of the 14 participants were men; the mean age was 31. Over the course of the study, each participant ingested each form of aspirin; 1,950 milligrams of aspirin (the equivalent of six regular aspirin tablets) was administered every time. Measurements of blood showed clearly that aspirin was absorbed fastest when administered in chewable form and swallowed. “This supports the recommendation to use chewable [aspirin] formulation in the treatment of ACS,” the researchers say. ACS refers to “acute coronary syndrome,” the general medical term meaning heart attack or sudden onset of angina.

Current guidelines call for giving heart attack patients one aspirin tablet and for them to chew it to speed up its anti-blood-clotting properties.

Aspirin works within 15 minutes to prevent the formation of blood clots in people with known coronary artery disease. One adult-strength aspirin contains 325 milligrams. The current study suggests that 325 milligrams of chewable aspirin would be preferred in the setting of a heart attack or sudden onset of angina ( chest pain). However, aspirin should still be taken under these circumstances if the chewable form is unavailable.

Aspirin use in patients with heart disease is common. People with known coronary disease often are told to take a “baby” aspirin (81 milligrams) daily to reduce their risk of heart attack of stroke.

At many blood donor services, you can choose to donate whole blood or just specific blood components. All donations are greatly needed and appreciated.

Whole blood
The main components that make up blood are red cells, platelets, plasma, and white cells. When most people give blood, they give a pint of “whole blood” which means a donation containing all four blood components. Each donation of whole blood is taken to the testing lab where the white cells are filtered out. The unit is then separated into the remaining components: platelets, plasma, and red blood cells.

If you donate through Inova Blood Donor Services or the American Red Cross, every donation is thoroughly tested, properly labeled, and carefully delivered to local hospitals.

Whole blood donors are eligible to give blood every 56 days.

ABC (automated blood collection) donation
Making an automated or “apheresis” donation means that you provide a particular blood component or set of components such as red blood cells, plasma and/or platelets. This technology enables us to collect specific components and return the uncollected components safely back to the donor via the automated process.

During the automated blood collection process, blood flows through single-use sterile tubing into a centrifuge chamber that “spins” your blood and separates the whole blood into various components. Each component is collected into a waiting bag. Component procedures take a little longer, but they are safe for you and highly efficient for patients. Each blood component is unique and important:

One platelet donation yields as many platelets as normally present in six whole blood donations. Platelets are given to help stop bleeding in patients recovering from cancer, leukemia, open-heart surgery, and transplant surgery. A platelet donation typically takes 90 minutes. You can donate platelets every 14 days.

One plasma donation yields as much plasma as three whole blood donations. Plasma carries clotting factors and nutrients. It is often given to trauma patients, organ transplant recipients, newborns, and patients with clotting disorders.

Red blood cells
One red cell donation yields as many red blood cells as two whole blood donations. Red blood cells carry oxygen and are often given to surgery and trauma patients and those with blood disorders such as anemia and sickle cell anemia. A red blood cell donation typically takes one to two hours. You can donate red cells every 56 days. You may also be eligible to donate double red cells. In this case, you are eligible t o donate every 112 days.

All blood types are needed for components. Component donations are safe for donors and make transfusions even more efficient and safe for patients.

Autologous blood donations
In rare instances, such as when someone has a unique set of markers or antigens in their blood or are about to undergo a highly complex surgical procedure, a physician may recommend that an individual have his or her blood drawn and reserved for the upcoming surgery.

In these cases, most blood donor services can draw and transfer blood to the hospital performing the surgery. If you are interested i autologous blood donation, please talk with your physician.

Blood that is drawn autologously and is not used during surgery is immediately and properly disposed of. The nature of autologous donations does not require that the donated unit(s) go through the same rigorous testing as blood donated for use by the general patient population.
