Objectives
In doing this research I wanted to understand more about Lipitor as a drug. The diseases it treats, its chemical components and its medical benefits. In addition to that I also wanted to know the toxicological and physiological effects on human body, its drawbacks and also look into its specific medical documents.
Introduction
According to Macmillan (2006), “drug can be best defined as substance used in the diagnosis, treatment, or prevention of a disease or as a component of a medication” (p. 302). Lipitor whose generic name is atorvastatin (Webster, 2009) is a synthetic lipid-lowering agent. It is an oral drug that lowers the level of cholesterol in blood. It belongs to a class of drugs referred to as statins, thus Lipitor is classified as a drug (Smith and Knapp, 1972). This research was intended to best understand the drug Lipitor. How it works and generally gets some vital information about the drug so that at the end of this research I can have a vivid understanding of its expected effects.
Materials and methods
This research was done by going through medical books and online journals medical articles. I also requested for clarification from Medical personnel who were of so much help as far as how the drug generally works is concerned and its side effects. I interviewed some patients that were under Lipitor dosage and also patients that have been treated using Lipitor dosage before. I also got information from the information printed on its pack.

Results
In my research I found out that The main ingredient in Lipitor is a chemical known as atorvastatin which is an inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme(Roberts, 2012). This enzyme catalyzes the conversion of HMG-CoA to mevalonate is catalyzed by this enzyme which in cholesterol biosynthesis is an early and rate-limiting step. Atorvastatin calcium has an empirical formula of (C33H34FN2O5)2Ca•3H2O with a molecular weight of 1208.43. (Webster, 2009).
Discussion
Atorvastatin which is the main ingredient in Lipitor works to lower cholesterol levels just like all other statins. It can also be said that Lipitor competitively inhibits HMG-CoA reductase (Webster, 2009). Lipitor works in a manner that it inhibits an enzyme in the human body that is very essential for the production of cholesterol (Roberts, 2012). Over time this the cholesterol levels in the blood to drop significantly due to these inhibiting effects. Lipitor is also used to help reduce the risk of having a heart attack or stroke in people who have high blood pressure and coronary heart disease (CHD) or who are at risk of CHD (Smith and Knapp, 1972).
It was found that Lipitor tablets that are used for oral administration contains the following: 10, 20, 40, or 80 mg atorvastatin and many inactive ingredients such as : Opadry White YS-1-7040 (hypromellose, polyethylene glycol, lactose monohydrate, NF; talc, titanium dioxide); polysorbate 80, NF; simethicone emulsion; calcium carbonate, USP; candelilla wax, FCC; croscarmellose sodium, NF; hydroxypropyl cellulose, NF;; magnesium stearate, NF; microcrystalline cellulose, NF. (Roberts, 2012)

When one uses Lipitor it leads to decreased elimination of atorvastatin that could increase levels of atorvastatin in the body and thereby increasing the risk of muscle toxicity from atorvastatin. Therefore, it is recommended that atorvastatin should not be combined with other drugs that decrease its elimination (Roberts, 2012). An example of such a drug is erythromycin (E-Mycin). Other than this Lipitor is associated with unexplained muscle pain, tenderness, or even weakness where one just feels so weak all over sudden. It is also associated with unusual tiredness fever and urine that is dark in color. In addition to these it is also associated with swelling, irregular urinating where one urinates less or even doesn’t urinate at all and also leads to weight gain. Among these side effects Lipitor also causes nausea, itching, clay-colored stool, yellowing of the skin and upper stomach pain. Other than the above mentioned Lipitor can cause serious muscle problems that can lead to kidney problems, including kidney failure and liver problems. (Smith and Knapp, 1972) Lipitor has so many benefits since it is a prescription medicine that lowers cholesterol in your blood. It helps to lowers the (“bad” cholesterol) and triglycerides in your blood thus making them to be in quantities so that they do not pose any health risk (Roberts, 2012). It can also raise your HDL-C (“good” cholesterol) as well, this is also very much recommended health wise. Lipitor is for people whose cholesterol does not come down enough when they do a lot of exercise and when they also take meals that are low in fat (Smith and Knapp, 1972).
. Lipitor also help to lower the risk of one getting an heart attack, stroke or even chest pain in patients who have heart diseases are exposed to risk factors for heart disease such as age, smoking, hereditary heart disease. (Webster, 2009)
Lipitor as a drug has quite a number of draw backs which in one way or the other really hinder its proper usage. For example Lipitor should not be taken by women who are pregnant or are thinking that they could be pregnant, or in one way or the other are planning to become pregnant (Roberts, 2012). This is because Lipitor could turn out to be very harmful to the unborn baby. If one gets pregnant, he or she is advised to stop taking stop taking Lipitor. The mothers who are breast feeding should also not use Lipitor since the content of the drug can pass into her breast milk and may harm the baby (Roberts, 2012). Lipitor cannot also be taken by those who are allergic to any of Lipitor’s ingredient. (Dr. E. Robbins, personal communication, October 18, 2012).
Conclusion
In my opinion Lipitor is quite a medical success since it has helped to solve quite a good number of medical complications. So I advice that one should obey the medical advice that come with it and one will surely acknowledge the benefits of treating him/herself with this drug.

Page 1 of 2 HBR Blog Network Lipitor and iPhone 4s: Setting the Stage for Industry Disruption by Christopher Bowe | 12:55 PM December 20, 2011 The two biggest product stories of 2011 were arguably Lipitor and the iPhone 4S. Although the two stories could not appear to differ more, both offer business leaders strategic lessons that are intriguingly similar. The Lipitor story seems to be about a managed end: the highly anticipated demise (due to the expiration of its patent last Nov. 30) of a blockbuster prescription drug. The iPhone 4S's story seems to be about a new beginning: the highly anticipated launch of the latest version of a blockbuster consumer-technology product. But they have fundamentally more in common than meets the eye. Both Pfizer and Apple use life-cycle management to explore a new way to drive the business and business model forward. In both instances, the lifecycle management innovation involves using disintermediation to change how the customer interacts with the product. And both teach lessons that apply across many industries. Lipitor's Long Good-bye Throughout its history, Pfizer's biggest product and the biggest-selling branded drug in pharmaceutical industry history, has delivered some confounding strategic lessons (http://blogs.hbr.org/cs/2011/11/say_farewell_to_lipitor_but_do.html) .

...three medications to her medication regime including Metformin 250mg two times per day, atorvastatin (Lipitor) 10mg daily, enalopril (Vasotec) 10mg daily. The addition of Metformin 250mg two times per day was added due to her newly diagnosed type II diabetes. Metformin is an oral diabetic medication that is used for type II diabetes and can be used with or without the use of insulin to aide in controlling blood sugars. Metformin is contraindicated in patients with renal disease or dysfunction, acute or chronic metabolic acidosis, including diabetic ketoacidosis, with or without coma and should be temporarily discontinued when a patient is having radiologic studies that involve intravascular administration of iodinated contrast because these medications may result in acute alteration on the patient’s renal function. Atorvastatin (Lipitor) 10mg daily was added due to the patient verbalizing she eats fast foods, her diet and meals are not regular, and she is overweight. During her hospitalization she required a heart catheterization and angioplasty. Atorvastatin, when used in patients with type II diabetes, reduces the risk of a myocardial infarction and stroke. Atorvastatin helps reduce levels of low-density lipoprotein, commonly known as LDL or “bad” cholesterol and increase the levels of high-density lipoprotein, or “good” cholesterol in the blood. Atorvastatin (Lipitor) is contraindicated in use with patients with acute liver disease, and pregnant or nursing......

...Drug Study Atorvastatin(lipitor) fourty mg one tablet once a day at HS eight pm DRUG CLASS AND MECHANISM: Atorvastatin is an oral drug that lowers the level of cholesterol in the blood. It belongs to a class of drugs referred to as statins, which includes lovastatin (Mevacor), simvastatin, (Zocor), fluvastatin (Lescol), and pravastatin (Pravachol) and rosuvastatin (Crestor). All statins, including atorvastatin, prevent the production of cholesterol in the liver by blocking HMG-CoA reductase, an enzyme that makes cholesterol. Statins reduce total cholesterol as well as LDL cholesterol in blood. LDL cholesterol is believed to be the "bad" cholesterol that is primarily responsible for the development of coronary artery disease. Reducing LDL cholesterol levels retards progression and may even reverse coronary artery disease. Atorvastatin also raises the concentrations of HDL ("good") cholesterol that protects against coronary artery disease and reduces the concentration of triglycerides in the blood. Indications Reduce risk of stroke & heart attack in type 2 diabetes patients without evidence of heart disease but with other risk CV factors Reduce risk of stroke, heart attack and revascularizations procedures in patients without evidence of coronary heart disease (CHD) but with multiple risk factors other than diabetes (eg, smoking, HTN, low HDL-C, family history of early CHD) Patients with CHD to reduce risks of MI, stroke, revascularization procedures,......

Supply and Demand

...prescription drug that recently lost its patent is Lipitor. It is a cholesterol-lowering drug. It has been a top selling drug for several years, totaling over seven billion dollars in sales in the US and a combined total of over ten billion dollars worldwide in 2010. Lipitor’s patent expired on November 30, 2011 making the drug available to be manufactured as a generic drug, therefore increasing affordability to consumers. Until May 2012, Ranbaxy had the sole rights for creating Lipitor’s generic form after the patent expired; after that, it was made available to other drug companies. Pfizer continued to market Lipitor after its patent expired and had spent over eighty seven million dollars in marketing, to generate three hundred eighty three million dollars in the first quarter of 2012. Market power shifted from Pfizer to other drug manufacturers with the expiration of the patent (Hughes, 2012). When a brand name prescription drug such as Lipitor is developed with a patent protection, it is essentially an inelastic demand meaning it was only produced by one manufacturer. It continued to be an inelastic demand due to the effect of this drug in lowering people’s cholesterol. Consumers who needed a drug to control their cholesterol had to go to Pfizer to get Lipitor. Since Lipitor continued to have its patent protection the price was controlled by this manufacturer. Once the patent expired, as in the example given above of the Lipitor drug, then the demand may be......

Lipitor Is one of the best example illustrating how Pfizer manages to sale more branded during its patent and continues the same even after it lost its patent in December 2011. • Advertising directly to consumers during patent years to boost the usage from 2000 to 2010. • Pfizer introduced coupons for patients and paid good rebates to insurer and PBM’s as an incentive for continuous use of branded drug even after the launch of generic. Thereby continuing sales roughly 3 times more than expected when a drug loses patent protection. • During the last year of patent protection Pfizer increased the drug price while it was still under patent from $1,290 per patient/year in 2006 to $1,939 in 2011. • Pfizer not only paid Ranbaxy to delay its launch of initial generic for Lipitor but also launched a generic via Watson, sharing 70% of its Lipitor related profits (1).

Alex _______ Assignment #3: Research Report November 15, 2012 Attempting to establish an internship with Pfizer Inc at this point in time is not in the best interest of Daniel University or its students. The first reason that makes Pfizer Inc. a less than ideal match for Daniel University's internship program is its history of ethical misconduct, especially bribery. In addition, the loss of market exclusivity of Lipitor has resulted in a sharp decline in sales as cheaper generic options have cut into Pfizer's market share. Finally, the decline in sales as a result of the loss of market exclusivity on drugs such as Lipitor has forced Pfizer Inc to resort to drastic cost cutting measures, which may hamper the company's growth potential in the long run and leave post-internship employment prospects for Daniel University students bleak. History of Ethical Misconduct Pfizer Inc has a history of ethical misconduct which heavily incorporates bribery of foreign officials and physicians. Kara Brockmeyer, chief of the division of the S.E.C. that enforces the Foreign Corrupt Practices Act (FCPA) has been quoted stating that, “Pfizer subsidiaries in several countries had bribery so entwined in their sales culture that they offered points and bonus......

...Reading and Interpreting Drug Labels: Lipitor and Accutane Lipitor: The actual name of the drug is “atorvastatin”. The name suggests that it is a “statin”, which is a type of medication which blocks an enzyme in the liver, preventing it from creating cholesterol, in order to lower the cholesterol level in the body (Pfizer, 2010). By lowering the cholesterol, atorvastatin helps to prevent heart disease, heart attack, stroke and vascular disease by preventing the hardening of the arteries (EMedicine Health, 2010). Along with proper diet and exercise, Lipitor is proven to lower bad cholesterol by 39-60% (Pfizer, 2010). Certain things such as alcohol and grapefruit should be avoided while taking Lipitor to avoid disruption of the drugs designated duties. Accutane: This drug is Vitamin metabolite class as first generation of retinoid (Isotretinoin, 2007). Its main mechanism is to inhibit sebaceous gland differentiation and decrease sebaceous gland size. The main indication for administrating this medication is mainly treat severe nodular acne, reduces the amount of oil released by the oil glands in your skin and helps your skin renew itself quickly (Isotertinoin, 2007).

Pfizer-Wyeth

...Pfizer – Wyeth Acquisition Abstract The board of Pfizer, the world’s largest drug maker, has agreed to acquire a long-time rival, Wyeth, for $68 billion. The Pfizer-Wyeth merger will create a prescription pharmaceutical company of extraordinary scale. Despite long-term patent and marketing challenges, most industry observers believe Pfizer has little choice but to engage in some type of major acquisition, especially given the recent loss of income on Lipitor. Pfizer needs to reassure its investors that it can get back on track. With having to freeze its dividends, hundreds of layoffs, and stock prices falling, it is imperative to convince the stakeholders that Pfizer will come out of this economic dilemma on top. The acquisition with Wyeth will reduce Pfizer’s negative sales outlook; however, there is only one route to delivering profit growth to investors, and that is by buying growth and cutting costs. Pfizer has announced that it expects to create savings of $4 billion by the third year after closing the acquisition. This is in part due to the 15% reduction in Pfizer-Wyeth’s combined workforce. After the merger, Pfizer will operate through a patient-centric business units in two major areas, biopharmaceuticals and diversified businesses. Its biopharmaceutical business units are emerging markets Where as Pfizer currently has one of the largest sales forces in the industry, Wyeth’s antibiotics and specialty drugs will not require a lot of marketing to......

... I believe all of us know Lipitor and now taking it frequently, here are news about Lipitor and I know you would like to hear. Pfizer’s Lipitor was so nice that we choose to take before. The company made every efforts to brand its Lipitor and we know it is really good to use. Now the most important thing is, the Lipitor will move from a lower price to a higher price while we cannot do anything about that since the decision was made by the Pharmacy and Therapeutics Advisory Committee. But-- We have a new choice—the generic lipid regulator. Don’t worry it is not a fake drug, just because of the patents expiration, drag companies other than Pfizer can produce generic versions. You may heard that the generic prescriptions increased every year quickly, for example, nearly 6% in 2009 and covered 75% of all prescriptions written in the U.S. The generic versions are safe and mature enough. I know you guys may not care about the money but just the result, or just habit to take Lipitor. The clinical trials established that they were as safe and as effective as brand name drugs such as Lipitor. Why we need to know this? It’s the time to switch. You know GHCM used a three-tier system for co-pays depends on the plan and prescription. Raising of the co-pay (to tier3 which is 100% higher than tier1) is made for Lipitor due to Lipitor’s price changing. It’s the time to make a better choice. Below are lists of the generic substitutes for Lipitor that all belong to Tier1. You...

...using Lipitor as an example. What is market Segmentation? Segmentation is a process of processing a large homogenous market into clearly defined identifiable segments with a main aim of designing a marketing mix to match target customers expectations. The basic factors that affect market segmentation are: [1] a) Clear identification of segment b) Determining the effective size of segment c) Promotion of the product to segments d) Using appropriate policies and resources of firm There are few main basic strategies that influence pharmaceutical customer segmentation. They are: a) Demographic ( age, income, sex etc) b) Socio-economic ( social class, stage in family life cycle) c) Geographic factors d) Psychological factors (lifestyle, personality traits) Other factors include perceptual, brand loyalty patterns and medical condition. [2] Segmentation of market is one of the crucial elements of marketing strategy. Criteria depend mainly on nature of market, therefore creating a problem in deciding the actual method. Maslow hierarchy of needs also explains about satisfying the customer needs in a vertical arranged pyramid with primary psychological needs at the bottom step and with self-actualization needs at highest step with safety needs, belonging needs and esteem needs as intermediate steps in the hierarchy.

Charles Pfizer started the company in Williamsburg, Brooklyn in 1849. During World War II, Pfizer became concretely established as one of the United State’s top drug companies by producing the antibiotic penicillin for soldiers out at war aboard. By the 1950's, Pfizer began to establish headquarters in Belgium, Brazil, Canada, Cuba, Mexico, and England. This gave Pfizer a platform to be able to compete globally. Expanding aboard is a powerful concept that most companies during this time did not consider. In 2000, Pfizer merged with Warner-Lambert in order to acquire full rights to Liptor. Lipitor is a popular drug used to lower cholesterol levels in the body. In 2002, Pfizer decided to participate in another merger with Pharmacia. This strategic action lead Pfizer to become the world's largest pharmaceutical devoted solely to healthcare. Of course we all know that this was not the only reason why Pfizer wanted to merge with Pharmacia. Pfizer’s underlying reason for merging with Pharmacia was to gain the rights to the drug Celebrex. Celebrex is used to treat osteoarthritis, rheumatoid arthritis, acute pain, painful menstruation and menstrual symptoms Pfizer Inc. is currently made up of three major core business segments.

Pay for Delay

...producing cheaper, alternative drugs. In an article written by Marian Wang, she discusses a particular case in which Pfizer makes “…a deal with certain pharmacy benefit managers … to block generic versions of Lipitor.”(Wang, Pfizer’s Latest Twist on ‘Pay for Delay’) There are a few ethical issues with this: one, the rival companies are infringing on patent laws, two, larger pharmaceutical companies are trying to create as much profit for their company until their patent runs out, and three, Americans in need of the drug are forced to pay higher prices for their drugs. The latter two issues go hand in hand with one another. Patents are used to protect a company’s invention and gives the company exclusive rights to sell that invention. In this case the invention is a drug. But, in the drug business, companies can get a hold of a drug and break down the chemical components making it easy to duplicate. It is not right for competitive companies to be able to easily break down a drug when all the hard work has been done by another and profit. Just because there have been minor adjustments with the chemical structure of the drug gives the rival company the right to market and sell their product. At the same time doesn’t having the exclusive right to an invention like Lipitor create a monopoly for Pfizer? That is what a patent does, it gives the inventor the sole right to sell the product without interference from competitors until either the patent expires, or becomes......

Pfizer Stock Analysis

...on the nature of the drug and the scope of the clinical trials process. In order to encourage companies to engage in innovation, companies are given lengthy patent protection for their drugs upon receiving regulatory approval. This allows them to control rates so that they may recover the development cost. A product brought to market is often highly lucrative, so success in the industry depends largely on the firm’s ability to bring product to market and capitalize on the monopoly rates. Pfizer is the world’s largest pharmaceutical firm, with annual sales near $50 billion. After the sale of its consumer health-care division to J&J, prescription drugs now account for more than 90% of sales. Top sellers include cholesterol-lowering Lipitor, Celebrex for arthritis, Viagra for impotence, and Lyrica for epilepsy and some types of neuropathic pain. Recently approved drugs with blockbuster potential include oncology drug Sutent and Chantix for smoking cessation. As most pharmaceutical companies’ in the market, in this type of business it is not simple since there is a lot of research and the development of new drugs in regular basis. Most stocks in the drugs industry have seen steadily growing revenue and earnings over the past three years, in which Pfizer has been declining revenue growth. In regards of stock dividend yield, Pfizer pays more dividends than most of the other companies in the industry. Therefore, since this company pays higher dividend yields and has grown......
