Consumer Reports Best Buy Drugs category; and cost less on average than other drugs in the category. Several of the Best Buys have been chosen because of their superior effectiveness or safety profile even though they may cost more. The project publishes Best Buy Drugs drug reports, the first three such reports covered Statins to reduce high cholesterol, heartburn drugs, and NSAIDs commonly used to treat arthritis. The project covers over 20 conditions and the most widely used drugs. The reports are published in web versions, and two-page PDF summaries in English and Spanish. More than half of all prescription drugs cause adverse effects—some serious
Discovery and development of statins must be metabolized to their active hydroxy-acid forms in order to inhibit HMGR. Type 2 statins all exist in their active hydroxy-acid forms. Fluvastatin has indole ring structure, while atorvastatin and rosuvastatin have pyrrole and pyrimidine based ring structure respectively. The lipophilic cerivastatin has a pyridine-based ring structure. Studies have shown that statins bind reversibly to the HGMR enzyme. The affinity of statins for HGMR enzyme is in the nanomolar range, while the natural substrate's affinity is in the micromolar range. Studies have shown that statins use the conformational flexibility of the HMGR enzyme that causes a shallow hydrophobic groove
