Ibuprofen And Acetaminophen

Investigating the effectiveness of the drugs Ibuprofen and Acetaminophen

Background:

Whenever we are in pain, let it be headaches or even back pain, the first source of remedy that we always seek is from over the counter painkillers such as Aleve and Advil. One of the problems or even a dilemma that we face between buying a painkiller is determining which painkiller would prove to be the most effective in remedying the pain and providing quick relief. When taking pain killers we also have to consider how quickly and how much should be absorbed in the blood to provide the maximum benefit. Some drugs need to be absorbed quickly in the blood

Although the same dosage of 200 mg was used for both ibuprofen and Acetaminophen, when comparing the AUC values and the Cmaxvalues it can be determined that Ibuprofen is more effective in providing quick pain relief when compared to Acetaminophen. Since we now have the AUC values, the rate of absorption and the rate of elimination of Ibuprofen and Acetaminophen can be determined through …show more content…
When the AUC was calculated, the area of each segment within certain time intervals were added up, For each of these individual segments the approximate area was calculated by finding the plasma concentration equation and integrating through definite integration. Finding the total AUC could be represented by the equation below:
AUC= t= 0t= Cptdt
Where Cptrepresents the Plasma concentration equation of each individual segment.
When observing the general shape of any pharmacokinetic profile, it is evident that they all follow the shape and curve of an exponential function.This allows us to express Cptas:
Cpt= Cp0e-kelt= DoseVe-kelt
We can now substitute this equation into the previous equation to create an analytical equation for determining AUC.
AUC= t= 0t= DoseVe-keltdt t= t1t= t2e-keltdt=e-kt-kt= t1t= t2= e-kelt2-k-

    The purpose of this experiment was to create and obtain pure acetaminophen. p-aminophenol and acetic anhydride were used to create acetaminophen and acetic acid. The acetic acid mixed with acetaminophen created an impure sample, which was purified through the addition of a water/methanol solution. The percent recovery of acetaminophen from the impure sample to the pure sample was 76%. The melting point of the pure sample was 167C - 169C.…

    In this TLC lab, we explored the relative polarities of Acetylsalicylic Acid, Ibuprofen, Acetaminophen, and Caffeine based on their functional groups. The most overall polar analgesic is considered to be the analgesic that contained the most polar function groups. The amine and amide functional groups are the most polar. In this experiment, we found that both these functional groups are found in Caffeine. As a result, Caffeine was the most polar out of Acetylsalicylic Acid, Ibuprofen, Acetaminophen, and Caffeine. Aside from Caffeine, Acetaminophen has one amide functional group. This makes it the second most polar analgesic. In addition, Acetylsalicylic Acid has an ester group. Since ester group is not as polar as either amine or amide groups,…

    The medication typically recommended first are NSAIDs (though not aspirin) or skeletal muscle relaxants and these are enough for most people. Benefits with NSAIDs; however, is often small. High-quality reviews have found acetaminophen (paracetamol) to be no more effective than placebo at improving pain, quality of life, or function. NSAIDs are more effective for acute episodes than acetaminophen; however, they carry a greater risk of side effects including: kidney failure, stomach ulcers and possibly heart problems. Thus, NSAIDs are a second choice to acetaminophen, recommended only when the pain is not handled by the latter. NSAIDs are available in several different classes; there is no evidence to support the use of COX-2 inhibitors over any other class of NSAIDs with respect to benefits. With respect to safety naproxen may be best. Muscle relaxants may be…

    Vicodin

    Vicodin is prescription medication that is used to treat moderate to severe pain in adults. The two main ingredients in Vicodin are Hydrocodone bitartrate and acetaminophen. Hydrocodone is considered to be a pain reliever that acts similarly to codine and is effective at decreasing the pain as well as relieving cough, however its can also cause drowsiness, mood changes, and metal “clouding”. Because of this reason the it can only be used when combined with another drug and not alone, as far as in the United States. Therefore its combined with acetaminophen, which is also a pain reliever along with a fever reducer. The combination of these two drugs helps improve acetaminophen’s effectiveness at relieving pain as well as limiting the potential abuse of Hydrocodone. The maximum dose of Vicodin is usually controlled by the amount of acetaminophen that it contains.…

    The midst, eldest and most long-standing substances used for the management of pain and other medical complications is opioids. It is well-known that the naturally occurring opioids (primarily morphine and codeine), the related endogenous opioid-like peptides and synthetic chemical substances have properties that can be indorsed to action that is mediated by binding at the various opioids receptors within the central and peripheral nervous systems. A number of opioids are available for clinical use, including morphine, hydromorphone, levorphanol, oxymorphone, methadone, meperidine, oxycodone, and fentanyl.…

    The concepts of this theory are the balance between analgesia and side effects, pain, and side effects themselves. Opioid analgesics often have very unpleasant side effects, so the end result is often patients taking less medication than they actually need, which results in pain not being effectively relieved. The combination of potent analgesics, pharmacological and non-pharmacological adjuvants can allow for the pain relief needed and also help minimize or eliminate unwanted side effects. Nurses can work with the patient to educate them on the side effects of potent medication and help them set realistic goals. This will entail working with both the patient and physician to achieve the results desired.…

    Analgesics:- analgesics are a medication which are used to relieve pain, this is done by blocking pain signals which are sent from the brain or by interfering with the signals. Analgesics are most commonly found in paracetamol and ibuprofen and are used for pain such as headaches. There are three common ways in which analgesics can be administered, these are; orally for moderate pain such as headaches, intravenous which is used in hospitals when an individual goes on a drip, epidurals are used when women are in labour.…

    As he comes off the field, an athlete notices he has a subtle pain in his shoulder. Determined to finish out the season strong, he takes two tablets of aspirin in hopes of healing the beginnings of an injury. What the athlete does not know about the painkillers could affect him later down the road, especially if he upholds his mentality of constantly taking aspirin whenever he senses an injury in the making. Painkillers are drugs that simply mask the pain many people suffer from on a daily basis. Globally, humans are using painkillers to cope with pains ranging from headaches to arthritis inflammation. Although painkillers offer many benefits, society has become too dependent on these instantaneous cures. When asked what invention they could not live without, twice as many people answered aspirin rather than their personal computer. Although the study was completed in 1996, the same holds true today.

    By examining the functional groups of the analgesic drug components, the relative strength of their polarities can be determined. For example, if a compound contains carboxylic acid, alcohol or amine functional groups, it should be very polar. If a compound contains ketone, aldehyde, ester, amide, or ether functional groups, it should be polar. Lastly, if a compound…
