About Crestor
Crestor (Rosuvastatin) is a prescription medication most often prescribed to adults who need to lower their cholesterol levels and reduce the risk of cardiovascular events such as heart attacks and strokes. It belongs to the class of drugs known as HMG-CoA reductase inhibitors, or “statins,” and works by targeting the liver’s production of low-density lipoprotein (LDL) cholesterol. In Singapore, Crestor is approved for the treatment of primary hypercholesterolaemia, mixed dyslipidaemia, and for secondary prevention of cardiovascular disease. The same active ingredient is available as a generic, which can offer a cost-effective alternative without compromising therapeutic effect.
What is Crestor?
Crestor is the brand name for rosuvastatin calcium, a synthetic analogue of a naturally occurring enzyme inhibitor. AstraZeneca, a multinational pharmaceutical company, introduced Crestor in the early -s after completing extensive phase III trials that demonstrated superior LDL-cholesterol reduction compared with several older statins. The pill is supplied in three strengths-5 mg, 10 mg, and 20 mg-allowing clinicians to start low and adjust upward based on each patient’s lipid profile and tolerance. Because the active molecule is identical to that found in generic rosuvastatin, the clinical efficacy and safety are expected to be equivalent, while the branded formulation may be priced higher. In Singapore, Crestor is classified as a prescription-only medicine, meaning a qualified health professional must authorize its use.
How Crestor Works
Rosuvastatin blocks the enzyme HMG-CoA reductase, which catalyses the rate-limiting step in the hepatic synthesis of cholesterol. By inhibiting this enzyme, the liver senses a shortfall of intracellular cholesterol and up-regulates LDL receptors on its surface. More receptors accelerate the removal of circulating LDL particles, leading to a rapid fall in plasma LDL-cholesterol-often observed within two weeks of the first dose. Rosuvastatin is highly lipophilic, facilitating efficient entry into hepatocytes, and it exhibits a long plasma half-life of approximately 19 hours. This extended duration supports once-daily dosing and contributes to steady-state concentrations that maintain lipid-lowering effects throughout the entire dosing interval. The drug is principally metabolised by the CYP2C9 pathway and eliminated unchanged via the kidneys, which explains why dose adjustments may be required in patients with severe renal impairment.
Why Crestor Is Used for Cardiovascular Conditions
-
Primary hypercholesterolaemia - Elevated LDL-cholesterol is a well-established risk factor for atherosclerotic plaque formation. By achieving reductions of up to 55 % in LDL levels, Crestor directly attenuates the substrate that fuels plaque buildup, thereby lowering the probability of future cardiovascular events.
-
Mixed dyslipidaemia - Many patients present with both high LDL and low high-density lipoprotein (HDL) levels. Rosuvastatin’s modest ability to raise HDL, together with its potent LDL-lowering, improves the overall lipid profile and aligns with guideline-recommended targets for mixed dyslipidaemia.
-
Secondary prevention after myocardial infarction or stroke - Clinical trials have shown that patients who continue statin therapy after an acute coronary syndrome experience fewer recurrent events. Crestor’s durable LDL suppression contributes to plaque stabilisation, reducing the likelihood of plaque rupture that precipitates heart attacks or ischemic strokes.
-
Familial hypercholesterolaemia (heterozygous) - Genetic mutations in the LDL-receptor gene cause markedly elevated cholesterol from birth. High-intensity statins such as rosuvastatin are often required to reach target LDL levels, and Crestor’s potent efficacy makes it a preferred option in this population.
These therapeutic rationales are reflected in local and international guidelines, including those issued by the Singapore Cardiac Society, which advocate statin therapy as a cornerstone of cardiovascular risk management.
Off-Label and Investigational Uses of Crestor
Although rosuvastatin is formally approved for lipid disorders, researchers have explored additional applications. Small-scale studies suggest that the anti-inflammatory properties of statins may confer benefits in conditions such as chronic kidney disease and certain autoimmune disorders, where reducing systemic inflammation could slow disease progression. Some clinicians occasionally prescribe rosuvastatin off-label for patients with elevated C-reactive protein who do not meet traditional lipid-lowering criteria. Off-label use only under qualified healthcare provider supervision.
Is Crestor Right for You?
Crestor is generally appropriate for adults with documented elevated LDL-cholesterol, a personal or familial history of cardiovascular disease, or those classified as high-risk by validated risk calculators. Patients with active liver disease, unexplained persistent elevations of transaminases, or known hypersensitivity to rosuvastatin should avoid the medication. As noted above, individuals with severe renal impairment may require a lower starting dose and close monitoring of renal function. Pregnant or breastfeeding women are excluded because statins can interfere with fetal cholesterol synthesis. In elderly patients, the once-daily dosing and modest drug-interaction profile make Crestor a convenient option, provided that renal function is assessed before initiation.
Taking Crestor Effectively
To maximise lipid-lowering benefits, Crestor is taken once daily, preferably in the evening because hepatic cholesterol synthesis peaks at night. The pill can be swallowed with or without food; however, a consistently timed intake helps maintain steady plasma concentrations. If a dose is missed, take it as soon as remembered unless it is close to the next scheduled dose-then skip the missed dose and continue with the regular schedule. Avoid grapefruit juice, which can inhibit CYP2C9 and potentially raise rosuvastatin levels, increasing the risk of muscle-related side effects. Regular blood tests to monitor lipid panels, liver enzymes, and renal function provide objective feedback on therapeutic response. Setting reminders on a smartphone or aligning the dose with a daily habit (e.g., brushing teeth) can improve adherence.
Understanding Side Effects and How to Manage Them
Most patients tolerate Crestor well, yet some may experience muscle discomfort, known medically as statin-associated myopathy. This occurs because excessive inhibition of cholesterol synthesis can disrupt muscle cell membrane integrity. Mild aches that resolve within a few days usually do not require discontinuation; instead, clinicians may recommend a temporary dose reduction or a brief holiday from therapy. More serious muscle damage-rhabdomyolysis-is rare but warrants immediate medical attention if a patient notices unexplained weakness, dark urine, or severe pain.
Elevated liver enzymes can arise in a small fraction of users, reflecting hepatic stress from altered cholesterol metabolism. Routine monitoring in the first three months helps identify transient elevations; if enzymes rise more than three times the upper normal limit, the prescriber may pause treatment.
Common, non-serious side effects such as headache or gastrointestinal upset often diminish with continued use. If symptoms persist, taking the medication with a small amount of food may mitigate gastric irritation. Patients should be alert to signs of allergic reaction-rash, itching, swelling of the face or throat-and seek urgent care if these appear.

Frequently Asked Questions
-
How quickly can I expect my cholesterol to improve after starting Crestor? Most patients see a measurable reduction in LDL-cholesterol within two weeks, with the greatest effect observed after four to six weeks of consistent dosing.
-
Can I take Crestor together with other cholesterol-lowering drugs? Combination therapy, such as adding ezetimibe, is sometimes employed when a single statin cannot achieve target levels. Your clinician will assess potential drug-drug interactions before prescribing any additional agents.
-
Is it safe to use Crestor if I already have high blood pressure? Yes; statins do not directly affect blood pressure. However, comprehensive cardiovascular risk management often includes both lipid-lowering and antihypertensive strategies.
-
What should I do if I experience muscle pain while on Crestor? Report the symptom to your healthcare provider promptly. They may order a creatine kinase test to evaluate muscle injury and adjust your dose if necessary.
-
Will Crestor interact with over-the-counter supplements like fish oil? Fish oil generally does not interfere with rosuvastatin metabolism, but combining multiple lipid-modifying agents should be discussed with a professional to avoid excessive lowering of triglycerides.
-
Can I switch from a generic rosuvastatin to Crestor without a dose change? Because the active ingredient is identical, the transition usually requires no alteration in strength, though monitoring is advisable during the switch.
-
Is Crestor appropriate for people over 75 years old? Age alone is not a contraindication; however, renal function commonly declines with age, so dose adjustments and periodic lab checks become more important.
-
Why do some guidelines recommend a “high-intensity” statin dose? High-intensity regimens aim for a ≥50 % reduction in LDL-cholesterol, which correlates with a more pronounced decrease in cardiovascular events for high-risk patients. Crestor’s 20 mg dose falls into this category.
-
Are there dietary restrictions while taking Crestor? No specific diet is required, but modest alcohol consumption and a balanced, low-saturated-fat diet support overall lipid control. Avoid large amounts of grapefruit juice, as it can raise rosuvastatin levels.
-
How does Crestor compare with other statins like atorvastatin? Rosuvastatin often achieves greater LDL-cholesterol reductions at comparable doses, partly due to its higher potency and longer half-life. Choice of statin depends on individual response, tolerance, and cost considerations.
-
Can Crestor help prevent heart attacks in people without high cholesterol? In certain high-risk groups, statins are prescribed for primary prevention even when cholesterol levels are near target. This practice is based on evidence that statins reduce plaque inflammation and stabilize arterial walls, lowering event rates.
