Statins like Lipitor, Crestor and Zocor
are the main medicines for this, and a lot of research shows they work.
To combat this, medication discount cards and Zocor
coupons are being made available for families and individuals without prescription coverage—and to those with insurance if it does not cover all needed prescriptions—offering discounts of ten to seventy-five percent on many popular prescription drugs.
This is illustrated vividly in the statin market, when Merck's Zocor
(simvastatin) lost patent protection in the previous decade: doctors wrote 22 million prescriptions for Zocor
in 2005; by 2007, after Zocor
lost patent protection, the number fell to less than 1 million.
The study, published in the July edition of Health Affairs, examines the generic substitution of simvastatin for the branded cholesterol drug Zocor
over six months beginning June 23, 2006, when Zocor
's patent expired.
The other component of Vytorin is Zocor
, which is already available as a generic.
Statin drugs such as Crestor, Lipitor, Pravachol and Zocor
were initially formulated to reduce LDL cholesterol.
For example, Datamonitor notes, the branded Zocor
drug and its generic Simvor alternative are both used to treat hypercholesterolemia, but while 28 Zocor
tablets cost Dh230, one can get 30 Simvor pills for just Dh99.
This drug alone or in combination with the popular statin drug Zocor
(simvastatin) conveyed no medical benefit to patients.
The Senate panel, along with the House's energy and commerce committee, have been examining how the two companies handled data comparing Merck's Zocor
against their jointly marketed drug Vytorin, a combination of Zocor
and Schering-Plough's Zetia.
In addition, if combined with Sustiva, the following drugs may require a change in the dose of either Sustiva or the other medicine: Ritadin (ritampin); Sporanox (itraconazole); Nizoral (ketoconazole); calcium-channel blockers (for example, Cardizem, Tiazac, and others); and the cholesterol-lowering medications Lipitor (atorvastatin), Pravachol (pravastatin), and Zocor
Some of these include Zoloft, for the treatment of depression and certain types of anxiety disorders, and statin Zocor
for high cholesterol levels.
