It has lots of product names around the world but is probably best known in the U.S. as Tylenol.
2. Ethinyl estradiol Top 3 products: Loestrin 24 Fe, Zarah, Diane 2011 sales: $3.05 billion Sales change: 22.3% I am not sure what it says that this ingredient in oral birth control pills falls second on the global list behind a headache remedy.
3. Omeprazole Top 3 products: Omeprazole, Mylan ($MYL); omeprazole, Novartis ($NVS); omeprazole, Teva Pharmaceutical Industries ($TEVA) 2011 sales: $2.59 billion Sales change: -4.5% This proton pump inhibitor treats stomach upset issues like peptic ulcers or gastroesophageal reflux disease. Think Prilosec in the U.S.
4. Amoxicillin Top 3 products: Amoxicillin, Novartis; amoxicillin/clavulanate; amoxicillin, Teva 2011 sales: $2.41 billion Sales change: 4.1% The antibiotic is used worldwide to treat bacterial infections including ear infections and gonorrhea. It is made by lots of generic drugmakers throughout the world.
5. Ibuprofen Top 3 products: Nurofen, Advil, Dolormin 2011 sales: $1.98 billion Sales change: 9% Whether it is known as Midol, Motrin, Cap-Profen or Advil, the pain reliever is used to ease the discomfort of everything from menstrual cramps to pain from arthritis.
6. Amlodipine Top 3 products: Amlodipine/benazepril, Teva; amlodipine/benazepril, Novartis; amlodipine/benazepril, Lupin Pharmaceuticals 2011 sales: $1.9 billion Sales change: 0.4% Pfizer ($PFE) controlled the sales of this blood pressure med, which it manufactured as Norvasc, for years.
7. Atorvastatin Top 3 products: Atorvastatin, Watson; atorvastatin, Ranbaxy Laboratories; atorvastatin, Apotex 2011 sales: $1.79 billion Sales change: 83.5% Look for this generic of Pfizer's ($PFE) king of all drugs, Lipitor, to top this list next year. In the first 6 months of this year, worldwide sales of generic Lipitor had already hit $1.7 billion, IMS Health reports.
8. Acetylsalicylic acid Top 3 products: Aspirin, Bayer; Kardegic; aspirin vitamin C, Bayer 2011 sales: $1.66 billion Sales change: 6.4% Even after being around for more than 100 years, aspirin continues to be one of the best-selling generics in the world. It was first isolated in 1897 by Bayer chemist Felix Hoffmann.
9. Simvastatin Top 3 products:Simvastatin, Teva; simvastatin, Novartis; simvastatin, Mylan 2011 sales: $1.64 billion Sales change: -0.5% Two years ago, before Lipitor went generic, this generic version of cholesterol reducer Zocor from Merck ($MRK) held the No. 7 spot currently occupied by atorvastatin. That two cholesterol-lowering molecules are in the top 10 globally says something about the health of the world.
10. Clavulanic acid Top 3 products: Amoxicillin/clavulanic acid, Novartis; amoxicillin/clavulanic acid, Teva; Augmentin 2011 sales: $1.63 billion Sales change: 8.4% This is the yang to the yin of amoxicillin, which lands at No. 4 on this list. Clavulanic acid is combined with the penicillin group of antibiotics to fight some forms of antibiotic resistance. It is generally reserved for bacterial infections caused by strains that are resistant to amoxicillin.
11. Fentanyl Top 3 products: Fentanyl, Mylan; fentanyl, Watson; fentanyl, Teva 2011 sales: $1.61 billion Sales change: 1.3% Fentanyl is used for breakthrough pain for conditions like cancer. But with its strength comes some issues with this opioid. About 5 years ago, Cephalon had to warn doctors to use it very carefully after at least three patients died and others experienced severe side effects because of improper dosing or substitutions, or because they should never have been given opioids in the first place.
12. Diclofenac Top 3 products: Voltaren; Torsilax; diclofenac, Sanofi ($SNY) 2011 sales: $1.61 billion Sales change: 15.5% Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID). It is often used globally to treat chronic pain associated with cancer as well as for conditions like arthritis or osteoarthritis. In fact, Covidien ($COV) uses it in a topical solution for osteoarthritis to reduce stomach upset.
13. Metformin Top 3 products: Metformin, Teva; Glucophage; Metformin, Mylan 2011 sales: $1.57 billion Sales change: 3.2% Given the pace at which people throughout the world are being diagnosed with and treated for diabetes, it is a little surprising that a molecule associated with a diabetes drug doesn't rank higher on this list. This oral drug is the go-to treatment worldwide for Type 2 diabetes.
14. Venlafaxine Top 3 products: Venlafaxine, Teva; venlafaxine, Upstate Pharma; venlafaxine, UCB 2011 sales: $1.57 billion Sales change: -2.6% The generics of this antidepressant have been available for about 6 years now but not yet for the extended-release version of Pfizer's drug Effexor XR. A number of retail pharmacy chains last year sued Pfizer ($PFE) and Teva, alleging that they colluded to delay generic versions of the extended-release version, a claim the two companies, of course, deny.
15. Salbutamol Top 3 products: Salamol; salbutamol, Mylan; albuterol, Nephron Pharmaceuticals 2011 sales: $1.57 billion Sales change: 9% Salamol, or salbutamol, has been around for more than 40 years and is the go-to inhaler product for people suffering from asthma.

16. Pantoprazole Top 3 products: Pantoprazole, Teva; pantoprazole, Novartis; Pantozol 2011 sales: $1.56 billion Sales change: -7.1% Like the molecule omeprazole, which is third on this list, pantoprazole is a proton pump inhibitor used to treat conditions like gastroesophageal reflux disease.
17.

Its detection in Russian cyclist Alexandr Kolobnev during the 2011 Tour de France was enough for him to bow out, although it was later determined that he had taken it for legitimate medical reasons.
18. Enoxaparin sodium Top 3 products: Enoxaparin, Novartis; enoxaparin, Sanofi; Versa 2011 sales: $1.53 billion Sales change: 198% The generics are copycats of the Sanofi anticoagulant Lovenox and came into the market in a big way two years ago, somewhat ahead of what Sanofi had expected.
19. Metoprolol Top 3 products: Metoprolol, Par Pharma; metoprolol, Watson; metoprolol, Wockhardt America 2011 sales: $1.53 billion Sales change: -1.7% This beta blocker is one that shows up around the world under a whole host of brand names and as generics.

In June, Actavis, now owned by Watson, brought the first third-party rival to the market.
