Drug Class: HMG-CoA Reductase Inhibitor (Statin) | Form: Oral Tablet | Prescription Status: Prescription Only (Rx) — DRAP Registered
What is Lochol 20mg Tablet?
Lochol 20mg contains Atorvastatin at a moderate starting or step-up dose — prescribed for patients requiring stronger LDL cholesterol reduction than the 10mg dose achieves, or as an initial dose for patients with moderate-to-high cardiovascular risk. It works by inhibiting HMG-CoA reductase — the liver's primary cholesterol-producing enzyme — reducing LDL cholesterol synthesis and simultaneously increasing the liver's clearance of LDL from the bloodstream. At 20mg, Atorvastatin typically achieves LDL reductions of 40–43% — providing meaningful cardiovascular protection for patients with elevated cholesterol, established heart disease, or significant cardiovascular risk factors.
What is Lochol 20mg Used For?
- Primary hypercholesterolaemia — elevated LDL cholesterol requiring stronger reduction than 10mg provides (خون میں کولیسٹرول کی زیادتی)
- Mixed dyslipidaemia — combined elevation of LDL cholesterol and triglycerides
- Cardiovascular risk reduction — prevention of heart attack, stroke, and cardiovascular events in moderate-to-high risk patients
- Familial hypercholesterolaemia — inherited high cholesterol requiring sustained statin therapy
- Secondary prevention — reducing recurrent cardiovascular events in patients with established coronary artery disease
How Does Lochol 20mg Work?
Atorvastatin competitively inhibits HMG-CoA reductase — reducing cholesterol synthesis inside liver cells. This triggers upregulation of LDL receptors on the liver cell surface, which pull more circulating LDL cholesterol out of the blood for processing and elimination. At 20mg, this dual effect produces greater LDL reduction than the 10mg dose — approximately 40–43% LDL lowering — along with meaningful reductions in total cholesterol, triglycerides, and VLDL particles, and a modest increase in protective HDL cholesterol.
Dosage and Administration
⚠️ Take exactly as prescribed alongside a cholesterol-lowering diet. Never stop without medical advice — cardiovascular protection requires consistent long-term therapy.
| Indication | Usual Dose | Frequency |
|---|---|---|
| Primary hypercholesterolaemia | 20mg | Once daily |
| Cardiovascular risk reduction | 20mg | Once daily |
| Familial hypercholesterolaemia | 20mg (titrated up as needed) | Once daily |
- Take once daily at any time of day — with or without food
- Take at the same time each day for consistent cholesterol control
- Swallow whole with a full glass of water
- Regular lipid panel and liver function monitoring required during treatment

Who Should NOT Take Lochol 20mg?
- Known allergy to Atorvastatin or any statin medicine
- Active liver disease or unexplained persistent elevated liver enzymes
- Pregnancy or planning pregnancy — statins are absolutely contraindicated in pregnancy
- Breastfeeding — Atorvastatin passes into breast milk; avoid use
- Currently taking strong CYP3A4 inhibitors without medical guidance
Consult your doctor before use if you have: history of liver or kidney disease, thyroid problems, personal or family history of muscle disorders, diabetes, or are taking other lipid-lowering medicines or CYP3A4-interacting medicines.
Side Effects
Common:
- Mild muscle aches or joint pain — usually mild and temporary
- Headache or dizziness
- Nausea or mild stomach discomfort
- Constipation or flatulence
- Mild elevation of liver enzymes — usually resolves without stopping treatment
Serious — seek medical attention immediately:
- Severe muscle pain, weakness, or tenderness — possible myopathy or rhabdomyolysis (یہ طبی ہنگامی صورتحال ہے)
- Dark brown or cola-coloured urine — sign of serious muscle breakdown affecting kidneys
- Liver problems — yellowing of skin or eyes (یرقان), severe abdominal pain, extreme fatigue
- Severe allergic reaction — facial swelling, difficulty breathing, widespread rash
Drug Interactions
| Medicine | Interaction |
|---|---|
| Gemfibrozil / Fibrates | High risk of serious muscle damage (rhabdomyolysis) — avoid combination |
| Cyclosporine / Tacrolimus | Significantly increases Atorvastatin blood levels — serious toxicity risk |
| Clarithromycin / Erythromycin | CYP3A4 inhibition increases Atorvastatin levels — muscle damage risk |
| Antifungals (Ketoconazole, Itraconazole) | Increases Atorvastatin exposure — dose reduction may be needed |
| Colchicine | Increased muscle damage risk when combined with statins |
| Grapefruit juice (انگور کا رس) | Inhibits CYP3A4 and increases Atorvastatin blood levels — avoid large quantities |
| Warfarin | Atorvastatin may increase anticoagulant effect — INR monitoring required |

Frequently Asked Questions (FAQs)
Q: What is the difference between Lochol 10mg and 20mg? Lochol 20mg delivers approximately 40–43% LDL reduction compared to around 30–35% with 10mg — your doctor will prescribe the 20mg dose when stronger cholesterol lowering is needed based on your lipid levels and cardiovascular risk profile.
Q: Do I need to take Lochol 20mg at a specific time of day? No — Atorvastatin can be taken at any time of day unlike older statins. Taking it consistently at the same time each day is what matters most for maintaining steady cholesterol-lowering effect.
Q: What muscle symptoms should I report immediately while taking Lochol 20mg? Unexplained muscle pain, tenderness, or weakness — especially accompanied by dark urine — must be reported to your doctor immediately as these can indicate serious muscle breakdown requiring urgent assessment.
Q: Can I stop taking Lochol 20mg once my cholesterol levels are normal? No — cholesterol returns to elevated levels within weeks of stopping statin therapy. Lochol 20mg is a long-term treatment; only stop under your doctor's guidance after a full review of your cardiovascular risk.
