Ibuprofen adverse effects

Most NSAIDs (e.g., ibuprofen, naproxen, and others) inhibit both COX-1 and COX-2 isoforms. That is, they are nonselective inhibitors of the COX enzyme system. Whereas inhibition of COX-2 is responsible for beneficial effects, inhibition of COX-1 is responsible for the most common and important adverse effects of NSAIDs. COX-2-selective inhibitors have been produced and marketed in attempts to preserve the beneficial effects of COX-2 inhibition while avoiding the deleterious effects associated with inhibition of the COX-1 enzyme. This approach has not been entirely successful, as discussed below. 

Recent advances with other anti-inflammatory drugs, ibuprofen and naproxen, which only work by physically blocking the channel to arachidonic acid, mean that the adverse effect of stomach bleeding can be avoided. 

For highly potent APIs, profound effects can occur at low ng levels, the adverse effect of ethynylestradiol on fish populations is one example [107]. Another example is the development of resistant bacterial strains induced by the release of antibiotics into the environment [112, 113]. Dome et al. [114] concluded that fluoxetine, ibuprofen, diclofenac, propranolol and metoprolol exhibit relatively high acute toxicity to aquatic species. In addition, due to the inherent properties of these chemicals, pharmacodynamic effects were observed in the heart rate of Daphnia magna for the (3-blockers propranolol and metoprolol. 

The drugs like ibuprofen, flurbiprofen, ketoprofen etc. possess antiinflammatory property similar to aspirin but toxicity and adverse effects are fewer and of lesser intensity. These preparations alone and in combination with other NSAIDs are used for treatment of inflammatory disorders. 

The incidence of upper gastrointestinal bleeding in over-the-counter use is low but still double that of over-the-counter ibuprofen (perhaps due to a dose effect). Rare cases of allergic pneumonitis, leukocytoclastic vasculitis, and pseudoporphyria as well as the common NSAID-associated adverse effects have been noted. 

Although the use of aspirin in treating fever in children is contraindicated (because of the association with Reye syndrome see Problems and Adverse Effects of Aspirinlike Drugs ), aspirin remains the primary NSAID used in treating fever in adults.9 Ibuprofen is also used frequently as a nonprescription antipyretic NSAID in both adults and children. 

Naproxen Anaprox, Naprosyn, others Similar to ibuprofen in terms of benefits and adverse effects... 

Ibuprofen Overdose of OTC ibuprofen manifests as a syndrome of coma, hyperkalemia with cardiac arrhythmias, metabolic acidosis, pyrexia, and respiratory and kidney failure. The treatment of adverse effects includes intubation, mechanical ventilation, fluid resuscitation, gastric lavage, and administration of activated charcoal.62 Interactions are similar to those of NSAIDs. Moclobemide enhances the effects of ibuprofen. 

A 23-year-old military officer on active duty took diazepam 5 mg tds and ibuprofen for back spasms. Three days later he was found sitting in a church, having assumed a previous role from his past life. He identified the date as 14 months before and his memory before that time was intact. However, he had no memory of events during the previous 14 months. There were no symptoms suggesting a schizophrenic disorder and his mental function was normal. His symptoms resolved within 24 hours of withdrawal of diazepam, except for amnesia of the event. He assumed his correct identity and was aware of the correct date. He had taken ibuprofen in the past with no adverse effects and this was his first exposure to a benzodiazepine. No other medications were involved and a full medical review found no cause for his symptoms other than diazepam use. 

The interaction of zaleplon with ibuprofen has been investigated in 17 subjects (23). Healthy adult volunteers were given zaleplon 10 mg alone, ibuprofen 600 mg alone, or zaleplon 10 mg plus ibuprofen 600 mg in an open, randomized, crossover study. The adverse effects were mild and resolved without intervention. The authors concluded that there was no evidence of a significant interaction between zaleplon and ibuprofen. 

Taking into account pharmacokinetics, adverse effects and clinical studies, ibuprofen may be considered the best choice in this patient, for the following reasons ... 

Non-steroidal Antiinflammatory Drugs (NSAIDs). In some cases, a patient may unknowingly be taking several different products that contain the same NSAID. An arthritic patient whose condition has been managed with ibuprofen obtained via prescription (often at dosage levels at or near the recommended maximum) may purchase a non-prescription ibuprofen product for pain/discomfort not associated with the arthritis. The patient may not know that the two products contain the same drug and that there is an increased risk of adverse effects. 

The incidence of adverse effects related to renal function in CLASS and VIGOR was low and similar (0.9% with celecoxib and 1.2% with rofecoxib). The incidence of increased creatinine and urea nitrogen concentrations was slightly lower in patients taking celecoxib than in those taking ibuprofen or diclofenac. Similar results have been documented in two other clinical trials. The... 

Flurbiprofen causes more gastrointestinal adverse effects than naproxen or ibuprofen. In a series of controlled double-bhnd studies, adverse reactions occurred in 27-42% of patients and were most commonly gastrointestinal in origin (18-28%) (SEDA-12, 85). 

High dosages of ibuprofen for 4 years were used in 41 patients with cystic fibrosis to slow progression of lung disease and only two adverse effects (conjunctivitis and epistaxis) were drug-related (SEDA-20, 93). 

Modified-release formulations seem to cause the same adverse effects as conventionally formulated ibuprofen (25), and four-times-daily treatment is better tolerated than twice-daily (SEDA-12, 86). 

A flu-like illness is the most common adverse effect of interferon beta. In an open, randomized study of the effects of paracetamol 1 g or ibuprofen 400 mg before and 6 hours after interferon beta injection on interferon beta-induced flu-like symptoms in 104 patients, the two drugs were equally effective (11). 

The spectrum of adverse effects of ketoprofen is similar to that of ibuprofen. 

The adverse effects of naproxen resemble those of ibuprofen. Any minor differences in frequency cannot be assessed with certainty. In 881 patients who had been followed for more than 3 years, only 8.9% dropped out because of adverse effects. In shorter studies, doses of up to 1.5 g/day produced no more adverse effects than lower or standard doses of other NSAIDs (1). 

Some rarer adverse effects, such as aseptic meningitis, have been reported with ibuprofen, suhndac, and tolmetin (37) in patients with systemic lupus erythematosus. A case-control study showed no increased risk of intracerebral hemorrhage in patients using aspirin or other NSAIDs in low dosages as prophylaxis against thrombosis (43). 

In 32 207 patients taking part in a short (1-4 weeks) postmarketing study of tolmetin, adverse effects occurred in 12%, and led to withdrawal in 3.6% (1). Tolerability was similar to that of naproxen, indometacin (SEDA-7, 114), and ibuprofen (SED-9, 152) (2). In another retrospective study in patients treated for 1 year or more with tolmetin, 64% reported generally mild transitory adverse effects. In controlled studies, about 10% of patients withdrew owing to adverse effects (3). In another study of 25 000 prescription records (4), tolmetin caused adverse... 

Studies of ibuprofen and other NSAIDs have produced toxic effects at concentrations 10 times therapeutic in cultured hepatocytes. No adverse effect on cell survival was noted at therapeutic concentrations of ibuprofen in this model, although increases in lactate dehydrogenase leakage were prominent. 

In the recent 8000-patient celecoxib long-term arthritis safety study [123], significantly more patients receiving traditional NSAlDs (ibuprofen or diclofenac) experienced clinically significant elevations in serum creatinine and/or serum urea nitrogen levels when compared to celecoxib. In an equally large gastrointestinal safety trial with rofecoxib, the incidence of adverse effects related to renal function for rofecoxib was similar to naproxen (1.2% versus 0.9%, respectively) [124]. When rofecoxib and celecoxib were directly evaluated in elderly hypertensive OA patients who manifested "normal" serum creatinine at the time of study recruitment, the overall incidence of clinically... 

Ibuprcfen is thought to be better tolerated than aspirin and indomethacin and has been used in patients with a history of gastrointestinal intolerance to other NSAIDs. Nevertheless, 5-15% of patients experience GI side effects. Less frequent adverse effects include thrombocytopenia, rashes, headache, dizziness, blurred vision, and in a few cases toxic amblyopia, fluid retention, and edema. Patients who develop ocular disturbances should discontinue the use of ibuprofen. Ibuprofen can be used occasionally by pregnant women however, the concerns apply regarding third-trimester effects. Excretion into breast milk is thought to be minimal, so ibuprofen also can he used with caution by women who are breastfeeding. 

Several NSAIDs, including aspirin, ibuprofen, and piroxicam, increase serum levels of methotrexate by interfering with its renal clearance. The adverse effects of methotrexate, including its hematotoxicity are predictably increased. The answer is (J). 

Adverse effects of naproxen is similar to that of ibuprofen. The most frequent adverse effects occuring are gastrointestinal disturbances. Peptric ulceration and gastro-intestinal bleeding have been reported, other side effects include headache, dizziness, nervousness, skin rash, pruritus, tinnitus, oedema, depression, drowsiness, insomnia, and blurred vision and other occular reactions. Hypersensitivity reactions, abnormalities of liver function tests, impairment of renal function including interstitial nephritis or the nephrotic-syndrome, agranulocytosis, and thrombocytopenia have occasionally been observed (5).
