Non steroidal anti inflammatory drugs adverse effects

NSAIDs have anti-inflammatory (reduce inflammation), analgesic (relieve pain) and antipyretic (lower temperature) effects. Although different NSAIDs have different structures, they all work by blocking cyclooxygenase (COX) enzymes. There are two main types of COX enzymes: COX-1 and COX-2. Both types produce prostaglandins; however, the main function of COX-1 enzymes is to produce baseline levels of prostaglandins that activate platelets and protect the lining of the gastrointestinal tract, whereas COX-2 enzymes are responsible for releasing prostaglandins after infection or injury. Prostaglandins have a number of different effects, one of which is to regulate inflammation. Most NSAIDs inhibit both enzymes, although a few are available that mainly inhibit COX-2. The pain-relieving and anti-inflammatory effects of NSAIDs are mainly due to inhibition of COX-2, and their unwanted side effects are largely due to inhibition of COX-1.

A Cochrane review of the analgesic efficacy of paracetamol and ibuprofen in the treatment of post-operative pain, concluded that combinations of paracetamol plus ibuprofen provided better analgesia than either medicine alone. 12 It was also concluded that the combination treatment reduced the need for additional analgesia to be administered and reduced the risk of adverse events occurring. 12 A study of approximately 900 patients using paracetamol or ibuprofen, or a combination of the two, for the treatment of osteoarthritis of the knee found significantly more patients achieved pain control at ten days and at 13 weeks with the combination treatment compared to paracetamol alone, but there was not a statistically significant difference compared to using ibuprofen alone. 15 In contrast, a small study of 90 patients randomised to one of three treatment groups in an emergency department setting found that combination treatment with paracetamol and ibuprofen did not provide more effective pain relief following musculoskeletal injury compared to either medicine alone. 16

Formulations of topical diclofenac, ibuprofen, ketoprofen, piroxicam, and indomethacin demonstrated significantly higher rates of clinical success (more participants with at least 50% pain relief) than matching topical placebo (moderate or high quality data ). Benzydamine did not. Three drug and formulation combinations had NNTs for clinical success below 4. For diclofenac, the Emulgel® formulation had the lowest NNT of (95% CI to ) in two studies using at least 50% pain intensity reduction as the outcome . Diclofenac plasters other than Flector® also had a low NNT of ( to ) based on good or excellent responses in some studies. Ketoprofen gel had an NNT of ( to ), from five studies in the 1980s, some with less well defined outcomes. Ibuprofen gel had an NNT of ( to ) from two studies with outcomes of marked improvement or complete remission. All other drug and formulation combinations had NNT values above 4, indicating lesser efficacy .

If I ever forget to change one of me patches, that’s horrible. It’s the worst feeling ever forgetting to change a patch.   Why’s that?   Because it’s the same kind of medication what they give heroin addicts so it’s, if you forget to change it you get bad withdrawal symptoms so I’ll start itching all over, feeling hot and cold, headaches, unable to sleep and that’s just forgetting to change one day. So it’s horrible.   Wow. What kind of patches are these, sorry, what’s the name of it?   It’s buprenorphine. It’s like a morphine based.   You mentioned the withdrawals there. You didn’t mention pain. Is pain something which gradually comes back as opposed to maybe in one day does the patch leave you in a lot of pain?   No, if, well, really I don’t notice the pain if I’ve forgot to change the patch because the withdrawals are that bad, I just can’t think about anything to be honest and it’s sent me into hospital a couple of times where I’ve forgot to change it and I’ve had a bad reaction just from forgetting to change it for one day.   When you were hospitalised, what were you suffering from then?   At the same time, I’d just started a new medication because I’d reacted wrong, badly to that and because I’d forgot to change the patch, they both reacted badly together and it sent me kind of crazy and my friends started getting worried about me so mum took me into hospital and I ended up going three days without sleep. So they had to give me something to just knock me out of it.   Okay. Do you mind just saying what you meant when you say you went a bit crazy?   Well, I started I actually started hallucinating because I’d had an allergic reaction at the same time as withdrawal symptoms so I’d actually gone over to my friend’s house and I just asked her if I were a butterfly and it kind of freaked her out so that’s why they says, “We’d better get you to hospital.”    Do you remember much about what happened?   Yeah, I remember it all. It were, I’d started twitching really badly and the doctor at A and E could see that something were happening and that and at first they said, “Oh, you’ve got to try and get some sleep.” “Oh, I can’t. I’ve been trying for three days.” So then they gave me some diazepam to knock me out and then after I’d actually got some sleep, the patches eventually started kicking in and I started feeling better after a couple of days.
