Ibuprofen/paracetamol, sold under the brand name Combogesic among others, is a fixed-dose combination of two medications, ibuprofen, a non-steroidal anti-inflammatory drug (NSAID); and paracetamol (acetaminophen), an analgesic and antipyretic. [6] It is available as a generic medication. [9] [10] [11]
Some patients request to be switched to a different narcotic due to stigma associated with a particular drug (e.g. a patient refusing methadone due to its association with opioid addiction treatment). [4] Equianalgesic charts are also used when calculating an equivalent dosage of the same drug, but with a different route of administration.
This decreases the possibility of using a higher dose of a single medication if the previous dose is ineffective in treating diseases or relieving symptoms. The significance of using drugs with optimal dose is lowering the occurrence of intolerable side effects, adverse reactions, and possible drug toxicity in patient's body. This increases the ...
Allowing sufficient time between doses of ibuprofen and immediate-release (IR) aspirin can avoid this problem. The recommended elapsed time between a dose of ibuprofen and a dose of aspirin depends on which is taken first. It would be 30 minutes or more for ibuprofen taken after IR aspirin, and 8 hours or more for ibuprofen taken before IR aspirin.
The brand first entered the American market in 1984 through Whitehall [3] (itself a division of Wyeth, which was purchased by Pfizer in 2009), [4] the same year ibuprofen gained Food and Drug Administration (FDA) approval for over-the-counter (OTC) sales in the United States (being available via prescription since 1974).

[1] Sometimes drugs cannot be compared across a wide range of treatment situations because one drug has a ceiling effect. [citation needed] Sometimes the desired effect increases with dose, but side-effects worsen or start being dangerous, and risk to benefit ratio increases. This is because of occupation of all the receptors in a given specimen.
Paracetamol (acetaminophen) class antipyretics, which have negligible anti-inflammatory activity. Apart from paracetamol itself, the medications in this class are mainly previously marketed drugs which were withdrawn owing to safety concerns, one example of this being phenacetin. A few other medications have antipyretic effects of varying strength.
For many drugs, severe toxicities in humans occur at sublethal doses, which limit their maximum dose. A higher safety-based therapeutic index is preferable instead of a lower one; an individual would have to take a much higher dose of a drug to reach the lethal threshold than the dose taken to induce the therapeutic effect of the drug.
