Question 1: Define what a painkiller is and explain its primary function in the body.

Answer: A painkiller is a medication that reduces or relieves pain by blocking pain signals or reducing inflammation. Its primary function is to alleviate discomfort caused by injury or illness.

Question 2: Describe the mechanism by which non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen reduce pain.

Answer: NSAIDs like ibuprofen reduce pain by blocking enzymes called COX which are involved in producing prostaglandins—substances that promote inflammation, pain, and fever. By inhibiting these enzymes, NSAIDs decrease inflammation and pain.

Question 3: Explain why painkillers might sometimes interfere with the immune response.

Answer: Some painkillers, especially anti-inflammatory ones, can suppress parts of the immune response by reducing inflammation, which is a key part of fighting infections. This may slow down healing or reduce the body's ability to fight pathogens.

Question 1: A patient is prescribed 200 mg of ibuprofen every 8 hours. Calculate the total amount of ibuprofen taken by the patient in 24 hours.

Answer: 600 mg

Question 2: If a painkiller reduces the production of prostaglandins by 70%, what is the remaining percentage of prostaglandin activity?

Answer: 30%

Question 1: Describe a simple experiment to test the effectiveness of a new painkiller. Include the variables, control measures, and safety precautions.

Answer: An experiment can involve two groups of volunteers experiencing similar pain levels. One group receives the new painkiller, while the control group receives a placebo. Variables include dosage and pain level. Controls include similar age and health status. Safety precautions involve monitoring for adverse reactions and obtaining informed consent.

Question 1: A study shows that after taking a certain painkiller, patients report a 50% reduction in pain within 30 minutes. If a patient initially rated their pain as 8 out of 10, what is their pain level after taking the medication?

Answer: 4 out of 10

Question 2: In a test, two different painkillers were administered to similar patients. Pain reduction was 65% with Drug A and 35% with Drug B. Which drug was more effective, and by what percentage difference?

Answer: Drug A was more effective, with a 30% higher reduction in pain.

Question 1: Explain how painkillers like NSAIDs can impact both pain relief and the immune response, including potential benefits and drawbacks.

Answer: NSAIDs relieve pain by reducing inflammation through enzyme inhibition, which decreases prostaglandin production. While effective at relieving pain, they can suppress parts of the immune response, potentially slowing healing and reducing infection fighting. Benefits include quick pain relief; drawbacks include possible delayed recovery and side effects such as stomach irritation.

Question 1: Discuss how the development of new painkillers can benefit industries such as pharmaceuticals and healthcare, and mention any ethical considerations involved.

Answer: New painkillers can improve patient comfort, reduce recovery times, and provide alternatives for those with allergies or side effects. Ethical considerations include ensuring safety through rigorous testing, avoiding overprescription, and preventing misuse or dependency.
