Category Name Cardio-Diabetic β Lipid-Lowering Agent (HMG-CoA Reductase Inhibitor / Statin)
Common Indications
- Hypercholesterolaemia (high LDL cholesterol)
- Mixed dyslipidaemia (high triglycerides + low HDL)
- Prevention of cardiovascular events β heart attack and stroke in high-risk patients
- Familial hypercholesterolaemia
- Secondary prevention post-myocardial infarction or stroke
- Adjunct to diet in patients with elevated cardiovascular risk
Common Dosing
- Standard Adult Dose: 20 mg once daily, with or without food
- Preferred Timing: Evening or bedtime (cholesterol synthesis peaks at night)
- Dose may be adjusted to 10β80 mg based on lipid targets and tolerance
Always follow your doctor's prescribed dose and duration.
Common Side Effects
- Muscle pain, weakness, or tenderness (myalgia)
- Headache
- Nausea and constipation
- Elevated liver enzymes
- Diarrhoea or flatulence
Seek immediate attention for:
- Severe unexplained muscle pain or weakness β possible rhabdomyolysis
- Dark or cola-coloured urine
- Yellowing of skin or eyes
Common Interactions
- Fibrates (e.g., Gemfibrozil) β Increased risk of myopathy; avoid combination
- Cyclosporine, Clarithromycin, Itraconazole β Increase Atorvastatin levels significantly
- Warfarin β May enhance anticoagulant effect; monitor INR
- Colchicine β Increased risk of myopathy
- Grapefruit juice β Increases Atorvastatin blood levels; avoid
Special Instructions
| Condition | Guidance |
|---|---|
| π€° Pregnancy | Contraindicated. Statins may cause fetal harm. Discontinue immediately if pregnant. |
| π€± Breastfeeding | Contraindicated during breastfeeding. |
| πΊ Alcohol | Avoid excessive alcohol. Increases liver toxicity risk. |
| π Driving | No direct effect on driving ability. |
| π« Liver Disease | Contraindicated in active liver disease. Monitor liver enzymes regularly. |
| π« Kidney Disease | Use with caution. Renal impairment may increase myopathy risk. |
Mechanism of Action Atorvastatin competitively inhibits HMG-CoA reductase β the rate-limiting enzyme in hepatic cholesterol synthesis. This reduces intracellular cholesterol production, upregulates LDL receptors on liver cells, and increases clearance of LDL cholesterol from the bloodstream. It also lowers triglycerides and modestly raises HDL cholesterol, providing comprehensive cardiovascular lipid management.
Instructions to Take

- Can be taken with or without food
- Avoid grapefruit juice during treatment
- Do not crush or chew β swallow whole
- Report any unexplained muscle pain to your doctor immediately
- Do not stop without medical advice β lipid control requires continuous therapy
