25 advil?
what will that do
normal strength
Best Answer:
Mainly, ulcerations, hepatotoxicity and renal damage. There's also risk of some cardiovascular damage.
Advil is a popular brand of ibuprofen, an NSAID (non-steroidal anti-inflammatory drug)
The widespread use of NSAIDs has meant that the adverse effects of these relatively safe drugs have become increasingly prevalent. The two main adverse drug reactions (ADRs) associated with NSAIDs relate to gastrointestinal (GI) effects and renal effects of the agents.
These effects are dose-dependent, and in many cases severe enough to pose the risk of ulcer perforation, upper gastrointestinal bleeding, and death, limiting the use of NSAID therapy. An estimated 10-20% of NSAID patients experience dyspepsia, and NSAID-associated upper gastrointestinal adverse events are estimated to result in 103,000 hospitalizations and 16,500 deaths per year in the United States, and represent 43% of drug-related emergency visits. Many of these events are avoidable; a review of physician visits and prescriptions estimated that unnecessary prescriptions for NSAIDs were written in 42% of visits
Combinational risk
If a COX-2 inhibitor is taken, one should not use a traditional NSAID (prescription or over-the-counter) concomitantly.[1] In addition, patients on daily aspirin therapy (as for reducing cardiovascular risk or colon cancer risk) need to be careful if they also use other NSAIDs, as the latter may block the cardioprotective effects of aspirin.
Cardiovascular risk
A recent meta-analysis of all trials comparing NSAIDs found an 80% increase in the risk of myocardial infarction with both newer COX-2 antagonists and high dose traditional anti-inflammatories compared with placebo.
NSAIDs double the risk of development of symptomatic heart failure in patients without a history of cardiac disease. In patients with such a history, however, use of NSAIDs may lead to a more than 10-fold increase in heart failure
Overall, NSAIDs are estimated to be responsible for up to 20 percent of hospital admissions for congestive heart failure
Gastrointestinal ADRs
The main ADRs (adverse drug reactions) associated with use of NSAIDs relate to direct and indirect irritation of the gastrointestinal tract (GIT). NSAIDs cause a dual insult on the GIT – the acidic molecules directly irritate the gastric mucosa; and inhibition of COX-1 reduces the levels of protective prostaglandins.
Common gastrointestinal ADRs include:
* Nausea/Vomiting
* Dyspepsia
* Gastric ulceration/bleeding
* Diarrhea
Risk of ulceration increases with duration of therapy, and with higher doses. In attempting to minimise GI ADRs, it is prudent to use the lowest effective dose for the shortest period of time, a practice which studies show is not often followed.
There are also some differences in the propensity of individual agents to cause gastrointestinal ADRs. Indomethacin, ketoprofen and piroxicam appear to have the highest prevalence of gastric ADRs, while ibuprofen (lower doses) and diclofenac appear to have lower rates
Certain NSAIDs, such as aspirin, have been marketed in enteric-coated formulations which are claimed to reduce the incidence of gastrointestinal ADRs. Similarly, there is a belief that rectal formulations may reduce gastrointestinal ADRs. However, in consideration of the mechanism of such ADRs and indeed in clinical practice, these formulations have not been shown to have a reduced risk of GI ulceration.
Commonly, gastrointestinal adverse effects can be reduced through suppressing acid production, by concomitant use of a proton pump inhibitor, e.g. omeprazole; or the prostaglandin analogue misoprostol. Misoprostol is itself associated with a high incidence of gastrointestinal ADRs (diarrhoea). While these techniques may be effective, they prove to be expensive for maintenance therapy.
Renal ADRs
NSAIDs are also associated with a relatively high incidence of renal ADRs. The mechanism of these renal ADRs is due to changes in renal haemodynamics (blood flow), ordinarily mediated by prostaglandins, which are affected by NSAIDs. Prostaglandins normally cause vasodilation of the afferent arterioles of the glomeruli. This helps maintain normal glomerular perfusion and glomerular filtration rate (GFR), an indicator of renal function. By blocking this prostaglandin-mediated effect, NSAIDs ultimately may cause renal impairment. Horses are particularly prone to these adverse affects compared to other domestic animal species.
Common ADRs associated with altered renal function include:
* Salt and fluid retention
* Hypertension
These agents may also cause renal impairment, especially in combination with other nephrotoxic agents. Renal failure is especially a risk if the patient is also concomitantly taking an ACE inhibitor and a diuretic – the so-called “triple whammy” effect.
In rarer instances NSAIDs may also cause more severe renal conditions:
* Interstitial nephritis
* Nephrotic syndrome
* Acute renal failure
* Acute tubular necrosis
Photosensitivity
Photosensitivity is a commonly overlooked adverse effect of many of the NSAIDs. It is somewhat ironic that these anti-inflammatory agents may themselves produce inflammation in combination with exposure to sunlight. The 2-arylpropionic acids have proven to be the most likely to produce photosensitivity reactions, but other NSAIDs have also been implicated including piroxicam, diclofenac and benzydamine.
Benoxaprofen, since withdrawn due to its hepatotoxicity, was the most photoactive NSAID observed. The mechanism of photosensitivity, responsible for the high photoactivity of the 2-arylpropionic acids, is the ready decarboxylation of the carboxylic acid moiety. The specific absorbance characteristics of the different chromophoric 2-aryl substituents, affects the decarboxylation mechanism. While ibuprofen is somewhat of an exception, having weak absorption, it has been reported to be a weak photosensitising agent.
During pregnancy
NSAIDs are not recommended during pregnancy, particularly during the third trimester. While NSAIDs as a class are not direct teratogens, they may cause premature closure of the fetal ductus arteriosus and renal ADRs in the fetus. Additionally, they are linked with premature birth (Ostensen & Skomsvoll, 2004). Aspirin, however, is used together with heparin in pregnant women with antiphospholipid antibodies
In contrast, paracetamol (acetaminophen) is regarded as being safe and well-tolerated during pregnancy. Doses should be taken as prescribed, due to risk of hepatotoxicity with overdoses
Other ADRs
Common ADRs, other than listed above, include: raised liver enzymes, headache, dizziness
Uncommon ADRs include: hyperkalaemia, confusion, bronchospasm, rash. Ibuprofen may also rarely cause irritable bowel syndrome symptoms.
Most NSAIDs penetrate poorly into the central nervous system (CNS). However, the COX enzymes are expressed constitutively in some areas of the CNS, meaning that even limited penetration may cause adverse effects such as somnolence and dizziness.
