Crestor is in a group of drugs called “statins”. Crestor (Rosuvastatin) is used to modify abnormal levels of fatty substances in the blood called lipids, mainly high levels of cholesterol and triglycerides. Crestor is used in combination with a diet plan when changes to diet and exercise alone have failed to lower high cholesterol and triglycerides. It increases the level of good cholesterol in the blood and lowers the level of bad cholesterol. The usual recommended start doses are 10mg and 20mg.
The brand Crestor is manufactured by AstraZeneca and the generic Rosuvastatin is currently from PharmaScience in Canada (also known as Pms-Rosuvastatin, sometimes by Cobalt or by Actavis or Teva or Mylan or Sandoz). It may come from other international countries. Crestor is available in tablets of 5 mg, 10 mg, 20 mg, and 40 mg strengths.
