re: Seems like most pharmaceutical drugs that have been brought to market……

Many are. Many are only tweaks on already existing meds.

Prilosec to Nexium

Claritin to Clarinex

Zyrtec to Xyzal.

There’s a difference in finding drugs of the same class that are better like generations of cephalosporins (antibiotic) and a minor tweak of a molecule to make a new patent.

Others went with combo meds. Americans are so fricking lazy they will o my take one huge pill.

Caduet …… I believe was Amlodipine combined with a Statin

Exforge ….. think it was a BP pill (some ARB) with a diuretic?

Can’t recall name but it was Motrin 800/Prilosec 20mgs. Charge $100’s instead of $00.01’s for two separate pills.
