Does aspirin lower blood pressure？ | Detailed Explanation

Aspirin is a very common nonsteroidal anti-inflammatory drug (NSAID). It is used worldwide to alleviate pain, reduce inflammation, and lower inflammatory reactions. Due to its antiplatelet aggregation effect, aspirin plays an important role in preventing cardiovascular diseases such as myocardial infarction and stroke. Does aspirin lower blood pressure?

About this question, there is no consensus in the scientific community. There is some controversy and misunderstanding among the public and the medical community. This article will delve into the potential impact of aspirin on blood pressure and hope to help readers have a better understanding of aspirin and blood pressure.

Aspirin

Aspirin’s chemical name is acetylsalicylic acid. It mainly reduces prostaglandins’ production by inhibiting the activity of cyclooxygenases in the body. Prostaglandins participate in regulating physiological responses. Aspirin can then achieve anti-inflammatory, antipyretic, and analgesic effects. In the cardiovascular field, aspirin can inhibit platelet aggregation, and prevent thrombosis, therefore it is widely used to prevent heart disease and stroke.

Aspirin and blood pressure

Does aspirin lower blood pressure? Scientific research provides different insights. Different perspectives should be approached when we are about to discuss the aspirin and blood pressure relationship.

In short-term clinical trials, aspirin’s effect on blood pressure was minimal, a significant lowering effect was not shown. The use of aspirin does not immediately change the blood pressure reading.  That is the same in both healthy individuals and hypertensive patients. In some individuals, aspirin may indirectly lead to a slight increase in blood pressure, that is because of its impact on kidney function and reduction in prostaglandin production.

After some long-term observation and research, it can be found that among people who regularly take low-dose aspirin, hypertension’s incidence rate is low. However, this association does not imply a cause-and-effect relationship between the two. However, this does not imply aspirin and blood pressure have a causal relationship. That may be influenced by other health behaviors. In cardiovascular disease prevention, it is more common to use aspirin for the long term. However, there is limited evidence about its direct impact on blood pressure. Although aspirin helps reduce heart attack and stroke risk, it mainly prevents thrombosis rather than directly lowering blood pressure.

Some studies suggest that if patients take aspirin at night, that may have a slight positive effect on lowering morning blood pressure. This is believed because aspirin changes blood pressure’s circadian rhythm. However, this effect is usually mild, it is not sufficient as hypertension’s primary treatment.

Although the direct effect of aspirin on blood pressure is not clear yet, it may indirectly affect cardiovascular health through other mechanisms. For example, aspirin can reduce thrombosis, improve blood flow, and to some extent affect blood pressure.

Applicable users

Although for most people aspirin is relatively safe, it is not suitable for everyone. The following people should be more careful if they need to use aspirin. For patients with gastrointestinal problems, aspirin may exacerbate gastrointestinal diseases. Patients who are taking other NSAIDs should pay attention to something. If you use multiple NSAIDs simultaneously, that may increase gastrointestinal bleeding risk.

People with coagulation disorders should be aware of aspirin’s antiplatelet effect. That may increase bleeding tendency. If hypertensive patients have cardiovascular and cerebrovascular disease at the same time, aspirin may be used together with other antihypertensive drugs. Do remember the selection and use of aspirin should be guided by a doctor, that can ensure efficacy and reduce potential risks.

Attention

Although aspirin’s benefits are widely recognized, it has side effects. The possible side effects of aspirin include gastrointestinal discomfort, bleeding, etc. Individuals who already have gastric ulcers or other bleeding risks should pay extra attention if they need to take aspirin. People who use aspirin need regular examinations, it is very necessary. 

Patients at risk of cardiovascular and cerebrovascular diseases or renal insufficiency should especially focus on this part. This can help detect potential side effects in time, and then adjust the treatment plan. Aspirin may interact with other drugs, which will affect their efficacy or increase side effects. Therefore, it is important to have a detailed understanding of possible drug interactions, you’d better consult a doctor before starting to take aspirin. In addition to medication treatment, it is important to adjust lifestyle. You should maintain a healthy diet, regular physical activity, and avoid excessive drinking.

Conclusion

does aspirin lower blood pressure? Although aspirin has a slight impact on blood pressure in some cases, it should not be used as the primary antihypertensive drug. If you consider using medication, it is most important to follow medical professionals’ advice, which can help ensure the safety and effectiveness of the medication. You can make safer and more effective use of the advantages of aspirin in healthcare, and avoid potential risks at the same time.
