Acetaminophen Is A Common Pain Reliever And Fever Reducer Essay

The goal of this experiment was to find out active chemical components in Anacin and Tylenol, using Thin Layer Chromatography technique. This technique uses the difference in the intermolecular forcer and polarity to separate mixtures. Comparing Rf values were then used to determine the active chemical components in the two analgesics. The overall result was that Acetaminophen exists in Tylenol and Acetylsalicylic Acid exists in Anacin.

Aspirin, Caffeine and Salicylamide were extracted from an over-the-counter pain reliever (BC Powder). These components were separated by manipulating their solubilities by adjusting the acidity and basicity of the solution. By doing this, the three components were forced into conjugate acid (or base) forms, causing selective solubility in either an aqueous or organic solvent. These layers were then separated by use of a separation funnel. Once separated, the components extracted were characterized by measuring the melting point and performing a TLC analysis. Also, the recovered aspirin from the first part of the experiment was recrystallized and compared to that of the

Separation and Purification of the Components of an Analgesic Tablet. Cora Bruno, Lab Section E. Aspirin, Caffeine and Acetaminophen were separated from four analgesic tablets of Excedrin using extraction techniques. 5% wt/vol NaHCO3, 4M HCL, ethyl acetate and deionized water were used to separate the three active components. MgSO4 was used to dry each extraction. Aspirin was isolated using a hot water bath and weighed to determine the percent theoretical recovery and the actual percent recovery of aspirin. After separation, Aspirin (ASA), Caffeine (CAF), and Acetaminophen (ACE) were purified and identified using Thin Layer Chromatography (TLC). Standards and purified ASA, CAF, and ACE were spotted on the silica gel (stationary phase) of the

Discussion The third experiment of the semester involves identifying an unknown component of Panacetin, a common pain relief medication, separated and precipitated in the previous experiment. Although Panacetin’s label reports this third ingredient as Tylenol, there is controversy over the true classification of the third substance. This Panacetin label also reports that the unknown constituent makes up 50% of the composition of Panacetin, compared to aspirin’s 40% composition and sucrose’s 10% composition, meaning that it is currently unknown what half of the drug people ingest is identified as. Research results have failed to repeatedly show that the third component of Panacetin is Tylenol, which leads to the hypothesis

The goal of the experiment was to securely isolate pure acetaminophen from p-aminophenol using a synthesis reaction. Synthesis still remains an important tool for scientists conducting chemical reactions. Most synthesis relies on a long process that involves multiple chemicals reactions. In the synthesis of Acetaminophen, one reaction is performed and a four step process is used, Scheme 1. Multiple techniques was used to achieve this goal.

Acetic Anhydride and p-Aminophenol were heated in a vial attached to an air condenser to synthesize crude acetaminophen, resulting in 0.097 grams (47.48% yield). The crude acetaminophen was then recrystallized in a solvent of water and methanol over heat resulting in 0.082 grams (39.61% yield) of pure acetaminophen. Melting points of both crude and pure acetaminophen were taken, and found to be 165.9 - 170.9°C and 168.2 - 171.5°C, respectively. The literature melting point of acetaminophen is 169.5 – 171.0°C, indicating that our final product was pure.

Ever wonder about the chemical makeup of tablets that people take for pain relief? Before a tablet can be successfully made, the limiting and excess reactants must be considered. The limiting reactant will affect the amount of the product that can be made. Another reason why the starting reactants must be determined carefully is to make reduce the amount of the reactant in excess so that reactants are not wasted. This experiment uses an Alka-Seltzer tablet. Alka-Seltzer dissolves in water and is an antacid and a pain reliever1. The Alka-Seltzer tablet has many uses such as relief of headaches, ingestion, heart burns, or even upset stomachs2. The active ingredients in an Alka-Seltzer tablet is aspirin, also known as acetyl-salicylic acid (C8H12O4), citric acid (C6H8O7), and sodium bicarbonate (NaHCO3)2. The aspirin in the Alka-Seltzer tablet helps with pain relief. Because of the acid-base chemistry (Brønsted-Lowry), citric acid and sodium bicarbonate produce O2, which makes the tablet fizz when it is dropped in liquid. The Brønsted-Lowry theory shows how the Brønsted-Lowry acid donates a hydrogen ion while the Brønsted-Lowry base accepts the hydrogen ions3. The remaining NaHCO3 that is in excess post reaction with the citric acid is what is used to neutralize stomach acid which helps relief heart burn2. The problem in

The purpose of this lab is to investigate the composition of a compound suspected to be Panacetin, a type of pain-killer. Panacetin is typically made up of sucrose, aspirin, and acetaminophen, but the third component in this experiment is unknown. The unknown component is suspected to be a chemical relative of acetaminophen, either acetanilide or phenacetin. Using techniques such as extraction, evaporation, and filtration, the three components will be isolated based on their solubilities and acid-base properties. Then, the percent composition of Panacetin can be deduced based on the masses of the three dried components. The

The tragic deaths of seven people who died due to potassium cyanide-laced Tylenol capsules started as a disaster for Tylenol producer Johnson and Johnson. However, J&J communicated with their publics and the media proficiently, investigated their

Acetaminophen is a worldwide known drug used for aches and pains, but that is all that is thought of when the name is said. Because it is an over the counter medicine, nobody thinks about the effects it can have on you. In fact most people don't even read the warning label. In this paper, it will discuss all of the things nobody even bothers themself to look into. Such as common name/s, what it should be prescribed for, uses, side effects, warnings, drug interactions, and the chemical composition for it. This essay attempts to prove that Acetaminophen is more than just a benign remedy for discomfort.

| * 90% of customers uses aspirin based analgesics * Many of them are suffering from side effects such as upset stomach, irritation of the stomach lining, or an allergic reaction. * 10% of customers who generally visited doctors and who get prescription use acetaminophen thorough doctor’s recommendation.

During the 1900's, the McNeil company developed and established Tylenol into a well known and recommended analgesic. It has become recognized world wide as a safe brand of acetaminophen. The name Tylenol has become identified as a trusted, safe drug that people can easily purchase over the counter for their ailments. Tylenol is still recommended by doctors even though there was a cyanide scare in the history of the company. It has been discovered by my independent survey that consumers use Tylenol for their pet's needs also.

The market for acetaminophen was growing at a rate of 5:1 to that of aspirin. Studies had shown that the side-effects from acetaminophen were less than aspirin. Bristol-Myers could have used the change in consumer consumption pattern and the shifting demand between the 2 analgesic variants as a means for positioning Datril using an effective campaign strategy.

Sealed bottles were tampered with and extra-strength Tylenol capsules were replaced with cyanide-laced capsules. These bottles were then resealed and placed on shelves of pharmacies in the Chicago area. Seven people died as a result. Tylenol was called upon to explain why its product was killing people.

The product portfolio includes Acetadote® (acetylcysteine) Injection for the treatment of acetaminophen poisoning, Caldolor® (ibuprofen) Injection, the first injectable treatment for pain and fever approved
