Aspirina para mejorar la circulación y prevenir ataques al corazón.

Yo que siempre la tomaba en la manana la aspirina,...de ahora en adelante en la noche.

y ademas para el dolor tomaba ibuprofen que contrareacciona el efecto de la aspirina.... Bueno mas vale tarde que nunca el saberlo y ponerlo en practica.
Comparto este conocimiento con ustedes y algunos otros consejos sobre la aspirina.

Aqui en los Estados Unidos la aspirina usualmente lavenden en dosis de 325 mg; asi que hay que partirla en 4 para tener la dosis de 81 mg más o menos; y además ahorran en la medicina.

Ask Dr. Art:
Best time to take Aspirin

You've got medical questions, we know just who to prescribe: Dr. Art Ulene. Dr. Ulene is an AARP Foundation board member and is deeply committed to our efforts to improve the health and well-being of all seniors. He has appeared on NBC's Today Show and has led several national campaigns promoting health.

Q My doctor recently put me on 81 mg. of aspirin, once a day. What is the best time to take the aspirin?

A If your blood pressure is normal, take the aspirin at whatever time of day you are most likely to remember it.

If you have a slightly elevated blood pressure, or "prehypertension" (under 140 systolic and 90 diastolic), take your aspirin in the evening. Two studies have shown that, in people with prehypertension, the systolic blood pressure (the higher number) drops about five points and the diastolic pressure drops about three points when aspirin is taken before bedtime. No change occurs when the aspirin is taken in the morning.

Here are some other important tips about aspirin use from the National Library of Medicine (NLM) and the National Institutes of Health (NIH):

• If you forget a dose, take the missed dose as soon as you remember it—unless it's almost time for the next dose. In that case, you should skip the missed dose and resume your regular dosing schedule. Do not take a double dose to make up for a missed one.
  
• If you are using extended-release aspirin tablets, swallow them whole with a full glass of water. Do not break, crush, or chew them. (Chewable aspirin tablets may be chewed, crushed, or swallowed whole.
  
• If you are taking aspirin on a regular basis to prevent heart attack or stroke, do not take ibuprofen (Advil, Motrin) to treat pain or fever without talking to your doctor. Ibuprofen counteracts the benefit of daily aspirin therapy.
  
• The effects of aspirin on your blood-clotting capability last much longer than 24 hours (probably, for around five days). If you need surgery or any major dental work, be sure to tell your doctor or dentist that you are taking aspirin.
