Aspirin Background Aspirin Aspirin‚ or acetylsalicylic acid (ASA) is a salicylate drug‚ and is generally used as an analgesic (something that relieves pain without producing anaesthesia or loss of consciousness) for minor aches and pains‚ to reduce fever (an antipyretic)‚ and also as an anti-inflammatory drug. Aspirin works by prohibiting biological substances such as prostaglandins. Many different prostaglandins exist in the human body each serving a plethora of physical functions.

describe the functioning of Aspirin in our body‚ its various properties to fight pain‚ and its evolution over the years. Littlejohn describes how Aspirin claimed celebrity status as one of the world’s most popular‚ inexpensive painkillers by relieving headaches‚ sprains‚ blows‚ burns‚ swelling and fever. Furthermore‚ she added that Aspirin could also be used to reduce the risk of stroke and heart attack. The author supports the main idea by describing how the aspirin when taken with a modest stream

Freezing-Point Depression to Find Molecular Weight Abstract: In this lab‚ the purpose was to use the freezing point depression method to determine the molecular weight of aspirin. This was done by determining the freezing of t-butanol and that of a t-butanol and aspirin solution; then finding the molality of the solution‚ and moles of aspirin. In the results of the experiment‚ the molar mass was found to be 192.2 g/mol‚ which differed from the established value of 180.2 g/mol by 6.7% error. Introduction:

BMS3021 – Research Topic: Aspirin TOPIC SUMMARY Aspirin is able to inhibit the synthesis of the Thromboxane A2 precursor‚ by irreversibly binding to the COX-1 enzyme Lack of Thromboxane A2 means that there is no signalling for platelet aggregation so there is no blood clot formation‚ leading to its ability to act as a ‘blood thinner‘ SALT found that in a low-dose of 75mg of Aspirin a day‚ secondary prophylaxis of new cardiovascular events were reduced by 16-20% By decreasing the daily dose to 75mg

2005 September 23‚ 2005 OBJECTIVES The objective of this lab experiment is to prepare aspirin (acetylsalicylic acid) by reacting salicylic acid and acetic anhydride. INTRODUCTION This purpose of this lab was to prepare aspirin using its basic components: salicylic acid and acetic anhydride. Salicylic acid and acetic anhydride‚ along with an acid catalyst‚ react to form acetylsalicylic acid (aspirin) and acetic acid. In this reaction‚ the hydroxyl group on the benzene ring in salicylic acid

Separating the Components of "Panacetin" Submitted- July 17‚ 2012 Introduction 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

schemes using Dipotassium phosphate (K2HPO4) and Potassium hydroxide (KOH) to isolate the compounds of pure Acetylsalicylic Acid/Aspirin and N-(4-hydroxyphenyl) Ethanimidate/Acetaminophen respectively from Excedrin. The first reaction scheme to undergo acid-base organic extraction was to isolate the most acidic compound in Excedrin with a weak base‚ K2HPO4. We isolated the aspirin using aqueous base extraction‚ with Dipotassium phosphate then treated with HCl to force acidification. The mechanism for Scheme
