What is aspirin? What are its uses?

Aspirin (acetylsalicylic acid) belongs to the class of non-steroidal anti-inflammatory drugs (NSAIDs) and contains salicylic acid. It can reduce inflammation, fever, and relieve pain. Studies have shown that aspirin can also thin the blood, reducing the risk of heart disease or stroke caused by blood clots in the brain, so it is also considered a blood thinner.

What are the different forms of aspirin?

Aspirin comes in various forms, including:

Tablets, such as Panadol
Powder
Oral gel
Effervescent tablets.

What diseases/conditions is aspirin commonly used for?

Aspirin is commonly used to treat the following diseases or conditions:

Headache
Cold or flu
Sprains and strains
Menstrual pain
Long-term arthritis and migraines
Reduce the risk of cardiovascular disease (only applicable to some people)

Who should not take aspirin?

Have indigestion
Have asthma or other lung diseases
Have had clotting problems
Have liver or kidney problems

Will aspirin develop resistance?

The reason for the development of resistance to long-term use of aspirin is that aspirin fails to reduce the production of thromboxane A2, thereby reducing platelet activation and aggregation. Studies have shown that the causes of resistance include insufficient drug dosage and drug interactions, and methods to reduce resistance include reducing the production and activity of thromboxane and blocking platelet activation pathways.

How to take aspirin correctly?

Taking aspirin pills as an example, the common dosage is 300mg, and the specific steps for taking aspirin are as follows:

Dosage	Frequency	Maximum dosage
1-2 pills per dose	Every 4-6 hours (not less than 4 hours between doses)	Do not take more than 12 pills within 24 hours

In addition, taking aspirin requires the following precautions:

If you take aspirin to relieve short-term pain, such as toothache and menstrual pain, you generally only need to take it for 1 to 2 days.
If you buy aspirin on your own and need to take it for more than 3 days, you should consult a doctor or pharmacist.
If your aspirin is prescribed by a doctor, you should take it according to the doctor’s instructions.
If you need to take aspirin, ibuprofen, or naproxen at the same time, remember to consult a doctor first, as they are all oral non-steroidal anti-inflammatory drugs, and taking them at the same time may increase the chance of side effects.
If you have any questions about the medication, dosage, or method of taking it, you should consult a doctor first.

How to store aspirin?

There are several key points to storing aspirin, including:

Store in a sealed container
Keep out of reach of children
Store at room temperature and away from high temperatures and humidity
If the medicine emits a strong vinegar smell, it should be discarded.

Is aspirin addictive?

If aspirin and other painkillers are used to treat headaches for a long time, it may cause “medication overuse headache (MOH)”, which means that the headache problem appears after the drug’s efficacy decreases. Generally, stopping the medication can solve the problem.

What is the difference between aspirin and paracetamol?

Aspirin is an oral non-steroidal anti-inflammatory drug (NSAID) that contains salicylic acid, which can reduce inflammation, reduce fever, and relieve pain. Paracetamol is one of the painkillers, which can block or regulate the chemical substances responsible for producing pain signals and body temperature in the brain, and is used to reduce fever and relieve pain.
