Select two medications to compare their LDL reduction and side effects:
Crestor is a brand name for rosuvastatin, a high‑potency statin that lowers LDL‑cholesterol by inhibiting HMG‑CoA reductase. It’s prescribed for primary and secondary prevention of cardiovascular disease, and many patients wonder how it stacks up against other options. This guide walks through the key differences, helps you weigh benefits and risks, and shows when a switch might make sense.
Rosuvastatin belongs to the statin class, drugs that block the liver enzyme HMG‑CoA reductase, cutting the production of cholesterol. By reducing low‑density lipoprotein (LDL) levels, it cuts the risk of heart attacks and strokes. Typical patients include those with high LDL, a history of heart disease, or diabetes‑related lipid disorders.
Other widely used statins each have their own potency, dosing range, and side‑effect profile. Below are the most common rivals.
When patients can’t tolerate any statin, doctors turn to other mechanisms.
| Drug | Typical Dose Range | LDL Reduction % | Common Side‑Effects | Average Annual Cost (UK) |
|---|---|---|---|---|
| Crestor (Rosuvastatin) | 5-40mg daily | 45-55% | Muscle aches, mild liver enzyme rise | £150‑£250 |
| Atorvastatin | 10-80mg daily | 35-50% | Myalgia, GI upset | £120‑£200 |
| Simvastatin | 5-40mg daily | 30-45% | Interaction with grapefruit, muscle pain | £90‑£160 |
| Pravastatin | 10-80mg daily | 25-35% | Low‑grade liver enzyme elevation | £80‑£130 |
| Pitavastatin | 1-4mg daily | 40-50% | Rare muscle toxicity | £140‑£210 |
| Ezetimibe | 10mg daily | 15-20% | Diarrhea, abdominal pain | £70‑£110 |
| Alirocumab (PCSK9) | 75mg sub‑Q every 2 weeks | 50-60% | Injection site reactions, flu‑like symptoms | £3,000‑£4,500 |
If you need the strongest LDL drop in the shortest time, rosuvastatin’s 45‑55% reduction is hard to beat. It’s also less affected by food, so you can take it any time of day. Patients with severe hypercholesterolemia often start at 20mg and titrate up.
However, because rosuvastatin is more potent, the risk of muscle toxicity rises if you combine it with high‑dose fibrates or certain antifungals. For patients with chronic kidney disease (eGFR<30ml/min), dose‑adjustment is mandatory, making pravastatin or low‑dose atorvastatin safer choices.
Large meta‑analyses (e.g., JUPITER, HOPE‑3) show that high‑intensity statins cut major cardiovascular events by roughly 20% more than moderate‑intensity agents. Yet, reports of statin‑associated muscle symptoms (SAMS) hover around 10% in clinical practice. Rosuvastatin’s long half‑life (≈19hours) can aggravate SAMS in susceptible individuals.
For people prone to diabetes, modestly lower doses of atorvastatin or pravastatin may be preferable, as rosuvastatin carries a slightly higher signal for new‑onset diabetes in some trials.
When NHS formularies list generic rosuvastatin, the price gap narrows, but brand‑only packs still sit near £150‑£250 per year. In contrast, generic atorvastatin and simvastatin are often below £100. For patients paying privately, the cost differential can influence adherence, especially if a cheaper alternative offers comparable LDL reduction.
Non‑statin therapies like PCSK9 inhibitors are dramatically more expensive, so they’re reserved for familial hypercholesterolemia or statin‑intolerant cases where LDL goals can’t be met otherwise.
The conversation around lipid management also touches on LDL cholesterol - the specific “bad” cholesterol particle that statins target. Understanding your cardiovascular risk profile (age, smoking status, blood pressure) helps decide whether a high‑intensity statin like rosuvastatin is warranted. If you’re curious about lifestyle adjuncts, explore the impact of dietary saturated fat, exercise, and omega‑3 supplementation on lipid panels.

Most patients see a 30‑40% reduction within two weeks, with the full effect (up to 55%) reached by 4‑6 weeks of consistent dosing.
Yes, rosuvastatin can be combined with ezetimibe for additive LDL drops. Avoid high‑dose fibrates or certain antifungals (e.g., itraconazole) without medical supervision due to interaction risk.
Common issues include mild muscle soreness, headache, and occasional elevations in liver enzymes. Rarely, severe muscle breakdown (rhabdomyolysis) can occur, especially at high doses.
Patients with eGFR below 30ml/min should start at 5mg and avoid doses above 10mg. Regular monitoring of kidney function is recommended.
Generic atorvastatin typically costs £80‑£120 per year in the UK, whereas brand‑only rosuvastatin ranges from £150‑£250. Generic rosuvastatin narrows the gap but may still be pricier.
Switch if you develop persistent muscle pain, significant liver enzyme rise, or if you have contraindications like severe renal impairment. Non‑statin options like ezetimibe or PCSK9 inhibitors become relevant in statin‑intolerant cases.
When you look at the LDL‑reduction percentages, Crestor’s 45‑55% really stands out compared to the mid‑range statins. Its dose flexibility, from 5 mg up to 40 mg, lets physicians fine‑tune therapy without having to switch drugs. For patients with chronic kidney disease the lower renal clearance means we monitor levels a bit more closely, but the overall benefit often outweighs the risk. The modest rise in liver enzymes is usually reversible once the dose is adjusted. In practice, I’ve found the once‑daily regimen improves adherence for many folks.
Great rundown! If you’re trying to decide between Crestor and Atorvastatin, the extra 5‑10% LDL drop with Rosuvastatin can make a big difference for high‑risk patients. The side‑effect profile is pretty comparable, though some people report fewer muscle aches with Crestor. Cost‑wise, the UK price gap isn’t huge, but insurance coverage can tip the scales. For those who can’t tolerate statins, remember that ezetimibe and PCSK9 inhibitors are solid alternatives, especially when combined with a low‑dose statin.
Looks solid.
