With its more than 115 years of age, Aspirin™ can look back at a rich, long-standing history and exciting future. Thanks to its active ingredient acetylsalicylic acid, Aspirin™ is surprisingly versatile: not only does it stop pain, it is also effective in preventing cardiovascular events in appropriate at-risk patients.
Aspirin™ has been an important medicine for more than 115 years because of its remarkable pain relief, as well as cardiovascular (CV) event prevention, properties. It has withstood the test of time, and is an excellent case study in both science and branding. As a brand, Aspirin™ has been trusted over time by more consumers worldwide longer than any other over –the-counter (OTC) pain reliever.
As has been the case since the introduction of Aspirin™, acetylsalicylic acid (ASA), its active ingredient, continues to be used as the benchmark in pain relief and CV event prevention. At over-the-counter (OTC) doses, Aspirin™ offers the same pain-relieving properties as many molecules discovered decades later. It has been the most utilized pain reliever in history. As such, its efficacy and safety profile is well documented, which has certainly contributed to its remarkable longevity. Its anti-platelet and blood thinning properties separate it from all other category ingredients, and it is the only one to offer both pain relief and remarkable CV benefits. In fact, Aspirin™ is included in the World Health Organization’s list of essential medications based on its pain relief and anti-platelet effects.1
For CV event prevention, low-dose (81 mg–325 mg) Aspirin™ Cardio products are recognized for use – as directed by a physician – during suspected heart attack to help reduce damage to the heart, and as cornerstone therapy for reducing risk of recurrent CV events, specifically, heart attack and ischemic stroke. Furthermore, the drug is approved in more than 50 countries for the prevention of a first heart attack or stroke (primary prevention) in appropriate patients. In terms of safety, when used as directed for its approved cardiovascular indications, Aspirin™ is well-tolerated and effective, and, for the vast majority of patients, is infrequently associated with clinically relevant side effects. For prevention of CV events, more than 200,000 patients have been studied in more than 200 randomized clinical trials evaluating the safety and efficacy of Aspirin™. Serious bleeding rarely occurs.
GI bleeding has been shown to occur in less than 1% (41 of 6,300 patients) of those taking Aspirin™ to prevent a recurrent CVD event, such as a heart attack.4 A landmark meta-analysis showed that for patients taking low-dose Aspirin™ to prevent a first CV event, there was a positive benefit/risk ratio for Aspirin™ greater than 2:1.5 As with all drugs, the potentially life-saving benefits of longer-term, low-dose Aspirin™ therapy to prevent CV events such as heart attack and ischemic stroke must be weighed against its risks. Patients should work with their doctors to best determine if they are appropriate candidates for Aspirin™ therapy.
In a Bayer laboratory in Wuppertal, Germany, young scientist Dr. Felix Hoffmann is the first to succeed in synthesizing a chemically pure and stable form of acetylsalicylic acid (ASA), which becomes the active ingredient in Aspirin™.
Aspirin™ is registered as a trademark. It is launched on the market in powder form. Bayer delivers the medicine to pharmacies in small 250-gram glass vials. 500 mg of the powder is then weighed out and dispensed to customers in small paper bags. Just one year later, Bayer launches the analgesic in its classic tablet form – one of the first medicines to be marketed in this dosage form.
Aspirin™ becomes available without a prescription and becomes a best-seller in the USA.
Aspirin™ turns 50, and the following year, is for the first time featured in the Guinness Book of Records as the most frequently sold pain reliever in the world.

In the same year, the World Health Organization (WHO) introduces its “Essential Drug List”. Aspirin™ is included right from the start as an essential analgesic.
British pharmacologist Professor John Vane receives the Noble Prize for Medicine for his discovery that the anti-inflammatory properties of Aspirin™ result from its ability to inhibit the body’s production of certain chemical mediators (prostaglandins) that promote inflammation.

Results of the International Stroke Trial, with nearly 20,000 patients in 36 countries, are published. They support use of Aspirin™ within 48 hours after ischemic stroke.8
On March 6, exactly 100 years after Aspirin™ was entered into the trademark register of the Imperial Patent Office in Berlin, Bayer set a Guinness world record by transforming its 122 meter tall headquarters building in Leverkusen into the largest Aspirin™ box. The building is wrapped with more than 22,500 square meters of fabric to celebrate the 100th birthday of Aspirin™.

Bayer’s global Aspirin™ business continues to exhibit significant sales performance and remains one of the company’s top ten brands. Today, Aspirin™ is one of the top three branded over the counter analgesics worldwide.
Beginning with the launch in Germany (the birthplace of Aspirin™) New Aspirin™ is being introduced to consumers in countries throughout Europe and Latin America. The active ingredient of New Aspirin™, acetylsalicylic acid, is used in the form of microparticles that are on average 10 percent of the size of particles found in previous Aspirin™ tablets. Microparticles are combined with sodium carbonate, which acts as a disentigrant and local buffer, helping New Aspirin™ dissolve more quickly, enter the bloodstream faster, and relieve pain twice as fast as previous Aspirin™ tablets11,12.
