==== Acquisitions and mergers ====
In June 2000, Pfizer acquired Warner-Lambert outright for $116{{nbsp}}billion. To satisfy conditions imposed by antitrust regulators at the [[Federal Trade Commission]], Pfizer sold off or transferred stakes in several minor products, including RID (a shampoo for treatment of [[Head lice infestation|head lice]], sold to [[Bayer]]) and Warner-Lambert's antidepressant [[Celexa]] (which competes with Zoloft).<ref>{{Cite news |last=Hensley |first=Scott |date=June 20, 2000 |title=Pfizer Completes Stormy Takeover Of Warner-Lambert for $116 Billion |work=[[The Wall Street Journal]] |url=https://www.wsj.com/articles/SB961456765639278103 |url-access=subscription}}</ref> The acquisition created what was, at the time, the second-largest pharmaceutical company worldwide.<ref>{{Cite news |last=Campbell |first=Todd |date=May 15, 2017 |title=Here are the 7 biggest mergers of all time |publisher=[[Business Insider]] |agency=[[The Motley Fool]] |url=https://www.businessinsider.com/here-are-the-7-biggest-mergers-of-all-time-2017-5#6-warner-lambert-warms-up-to-pfizer-89-billion-2}}</ref>

In 2003, Pfizer merged with [[Pharmacia]], and in the process acquired [[G.D. Searle, LLC|Searle]] and [[SUGEN]]. Searle had developed Flagyl ([[metronidazole]]), a [[nitroimidazole]] antibiotic medication used particularly for [[anaerobe|anaerobic]] [[bacterium|bacteria]] and [[protozoa]].<ref name=":0" /><ref>{{Cite web |title=Metronidazole Monograph for Professionals |url=https://www.drugs.com/monograph/metronidazole.html |publisher=[[Drugs.com]]}}</ref> Searle also developed [[celecoxib]] (Celebrex) a [[COX-2 inhibitor]] and [[nonsteroidal anti-inflammatory drug]] (NSAID) used to treat the [[pain]] and [[inflammation]] in [[osteoarthritis]], [[acute pain]] in adults, [[rheumatoid arthritis]], [[ankylosing spondylitis]], [[painful menstruation]], and [[juvenile rheumatoid arthritis]].<ref>{{cite web |date=11 November 2019 |title=Celecoxib Monograph for Professionals |url=https://www.drugs.com/monograph/celecoxib.html |website=Drugs.com |publisher=American Society of Health-System Pharmacists}}</ref> [[SUGEN]], a company focused on [[protein kinase]] inhibitors, had pioneered the use of ATP-mimetic small molecules to block [[signal transduction]]. The [[SUGEN]] facility was shut down in 2003 by Pfizer, with the loss of more than 300 jobs, and several programs were transferred to Pfizer. These included [[sunitinib]] (Sutent), a cancer medication which was approved for human use by the FDA in January 2006.<ref>{{Cite news |url=https://www.bloomberg.com/news/articles/2005-11-20/the-spirit-of-a-startup-lives-on |title=The Spirit Of A Startup Lives On |work=[[Bloomberg Businessweek]] |date=November 21, 2005}}</ref><ref>{{Cite news |url=https://www.bizjournals.com/sanfrancisco/stories/2003/04/28/daily24.html |title=Pfizer expects to shutter South City biotech outpost |work=[[American City Business Journals]] |date=April 30, 2003}}</ref> A related compound, SU11654 ([[Toceranib]]), was also approved for [[cancer in dogs]], and the [[ALK inhibitor]] [[Crizotinib]] also grew out of a SUGEN program.<ref>{{Cite news |url=https://www.wsj.com/articles/SB10001424053111904009304576532892704206326 |title=FDA Approves Pfizer Lung-Cancer Drug |first=Jonathan D. |last=Rockoff |work=[[The Wall Street Journal]] |date=August 26, 2011 |url-access=subscription}}</ref><ref>{{cite book |doi=10.1016/B978-0-12-409547-2.12391-1 |chapter=Selective Kinase Inhibitors in Cancer |title=Comprehensive Medicinal Chemistry III |year=2017 |last1=Mortlock |first1=A.A. |last2=Wilson |first2=D.M. |last3=Kettle |first3=J.G. |last4=Goldberg |first4=F.W. |last5=Foote |first5=K.M. |pages=39–75 |isbn=978-0-12-803201-5}}</ref>

The introduction of the original, 7-valent version of the vaccine, developed by [[Wyeth]] in February 2000, led to a 75% reduction in the incidence of invasive pneumococcal infections among children under age{{nbsp}}5 in the United States. Pfizer introduced an improved version of the vaccine in 2010, for which it was granted a patent in India in 2017. Prevnar 13 provides coverage of 13 bacterial variants, expanding beyond the original 7-valent version.<ref name="wyethpr" /> By 2012, the rate of invasive infections among children under age{{spaces}}5 had been reduced by an additional 50%.<ref name="cdc.gov">{{Cite web |date=April 5, 2019 |title=CDC – ABCs: Surveillance Reports main page – Active Bacterial Core surveillance |url=https://www.cdc.gov/abcs/reports-findings/surv-reports.html}}</ref><ref>{{Cite web |last=Herper |first=Matthew |date=August 24, 2020 |title=In the race for a Covid-19 vaccine, Pfizer turns to a scientist with a history of defying skeptics – and getting results |url=https://www.statnews.com/2020/08/24/pfizer-edge-in-the-race-for-a-covid-19-vaccine-could-be-a-scientist-with-two-best-sellers-to-her-credit/ |website=[[Stat (website)|Stat]]}}</ref>
