Drug Class: Calcium Channel Blocker + ARB + Thiazide Diuretic Combination | Form: Oral Tablet | Prescription Status: Prescription Only (Rx) — DRAP Registered
What is Co-Extor 10/160/12.5mg Tablet?
Co-Extor 10/160/12.5mg is a fixed-dose triple combination tablet containing Amlodipine 10mg, Valsartan 160mg, and Hydrochlorothiazide 12.5mg — three proven antihypertensive medicines each targeting blood pressure through a completely different and complementary mechanism. It is prescribed for adults whose blood pressure is not adequately controlled on two medicines alone. The 12.5mg HCTZ strength delivers effective diuretic blood pressure reduction with a lower fluid and electrolyte burden — making Co-Extor 10/160/12.5mg a well-tolerated triple combination option for patients requiring stronger hypertension control. By combining all three medicines in a single tablet, Co-Extor simplifies treatment, improves daily adherence, and reduces the risk of heart attack (دل کا دورہ), stroke (فالج), and end-organ damage caused by uncontrolled high blood pressure (ہائی بلڈ پریشر).
What is Co-Extor 10/160/12.5mg Used For?
- Essential hypertension — treatment of high blood pressure in adults not adequately controlled on single or dual antihypertensive therapy (ہائی بلڈ پریشر)
- Resistant hypertension — blood pressure remaining above target despite two antihypertensive medicines at adequate doses
- Cardiovascular risk reduction — lowering the long-term risk of stroke, heart attack, and heart failure in high-risk hypertensive patients
- Simplification of therapy — replacing three separately taken antihypertensive medicines with one convenient once-daily tablet to improve treatment adherence
How Does Co-Extor 10/160/12.5mg Work?
Amlodipine 10mg — Calcium Channel Blocker: Amlodipine blocks calcium from entering blood vessel wall muscle cells — causing them to relax and widen. This reduces the resistance the heart pumps against, directly lowering blood pressure and improving blood flow to the heart, brain, and kidneys throughout the day.
Valsartan 160mg — Angiotensin Receptor Blocker (ARB): Valsartan blocks angiotensin II — a powerful hormone that narrows blood vessels and promotes sodium and water retention. By blocking its receptor, Valsartan relaxes blood vessels, reduces fluid retention, lowers blood pressure, and protects the kidneys and heart from the long-term damage caused by sustained uncontrolled hypertension.
Hydrochlorothiazide 12.5mg — Thiazide Diuretic: HCTZ acts on the kidneys to remove excess sodium and water through urine — reducing blood volume and directly lowering blood pressure. At 12.5mg, the diuretic effect meaningfully complements both Amlodipine and Valsartan while keeping the risk of electrolyte disturbances and excessive urination to a minimum.
Combined Triple Effect: Three separate blood pressure pathways targeted simultaneously produce significantly greater reduction than any single or dual combination — with each component at an optimised dose, minimising individual dose-dependent side effects while maximising combined therapeutic blood pressure control.
Dosage and Administration
⚠️ Always take exactly as prescribed by your doctor. Never stop Co-Extor suddenly without medical advice — abrupt discontinuation can cause dangerous rebound hypertension.
| Indication | Usual Adult Dose | Frequency | Maximum Daily Dose |
|---|---|---|---|
| Essential Hypertension | 1 tablet (10/160/12.5mg) | Once daily | 1 tablet |
Critical Dosing Rules:
- Co-Extor is not a first-line treatment — it is prescribed after blood pressure has been assessed on single or dual therapy and found inadequately controlled
- Blood pressure, kidney function, and electrolytes (potassium and sodium) must be checked before starting and monitored regularly during treatment
- Ensure adequate fluid intake throughout treatment — even the 12.5mg HCTZ dose can cause mild dehydration during hot weather or illness
- Elderly patients require closer monitoring for blood pressure lowering effects and electrolyte disturbances
- Never stop suddenly — always reduce the dose gradually under your doctor's direct supervision to avoid rebound hypertension
How to Take:
- Swallow the tablet whole with a full glass of water
- May be taken with or without food — take consistently the same way each day
- Morning dosing is preferred — HCTZ component increases urination and morning dosing avoids disrupting sleep
- If a dose is missed, take it the same day as soon as remembered — skip if it is the next day; never double the dose
Active Ingredients
| Ingredient | Strength per Tablet |
|---|---|
| Amlodipine (as Besylate) | 10mg |
| Valsartan | 160mg |
| Hydrochlorothiazide (HCTZ) | 12.5mg |
Who Should NOT Take Co-Extor 10/160/12.5mg?
Do not take if you:
- Are allergic to Amlodipine, Valsartan, Hydrochlorothiazide, or any sulphonamide-derived medicine
- Have severe kidney disease or are currently on dialysis
- Have severe liver disease or biliary cirrhosis
- Have uncontrolled low potassium (hypokalaemia) or low sodium (hyponatraemia)
- Have diabetes and are also taking Aliskiren — combination with Valsartan is contraindicated
- Are pregnant — Valsartan causes serious foetal harm and is strictly contraindicated in all trimesters (حمل میں سختی سے منع ہے)
- Are breastfeeding
Always consult your doctor before taking Co-Extor if you have:
- Mild to moderate kidney disease (گردے کی بیماری) — regular monitoring of kidney function required
- Mild to moderate liver disease — Amlodipine and Valsartan are both liver-metabolised
- Diabetes (ذیابیطس) — HCTZ can raise blood sugar levels
- Gout (گنٹھیا) — HCTZ raises uric acid and can trigger painful attacks
- Low blood volume or dehydration — risk of excessive first-dose blood pressure drop
- History of angioedema with any ARB or ACE inhibitor — swelling of face or throat
- Are elderly — increased sensitivity to blood pressure lowering and electrolyte disturbances
- Are taking potassium supplements or potassium-sparing diuretics
Side Effects
Common Side Effects:
- Ankle swelling (oedema) — Amlodipine related blood vessel dilation; common with calcium channel blockers
- Dizziness or light-headedness — especially when standing up quickly (postural hypotension)
- Increased urination — expected mild HCTZ effect; generally settles after the first few weeks
- Headache — mild and typically improves with continued use
- Fatigue or tiredness
- Flushing or feeling of warmth — Amlodipine related
Serious Side Effects — Stop Taking and Seek Medical Help Immediately:
- Severe hypotension — extreme dizziness, fainting, or collapse — particularly after the first dose, during illness, or with dehydration (طبی ہنگامی صورتحال)
- Angioedema — sudden swelling of face, lips, tongue or throat causing difficulty breathing — life-threatening emergency requiring immediate hospital care (یہ طبی ہنگامی صورتحال ہے)
- Severe kidney impairment — significantly reduced urination, unexplained weight gain, severe ankle swelling — requires immediate medical review
- Hypokalaemia (low potassium) — muscle cramps, weakness, or irregular heartbeat — potassium levels must be monitored regularly
- Severe allergic reaction — widespread rash, skin blistering or peeling — stop immediately and seek medical attention
- Photosensitivity — severe sunburn-like skin reaction after sun exposure — HCTZ related; use sun protection when outdoors
- Hyperglycaemia — raised blood sugar particularly in diabetic or pre-diabetic patients — monitor glucose levels regularly
Drug Interactions
| Medicine / Substance | Possible Interaction |
|---|---|
| Aliskiren (in diabetic patients) | Contraindicated with Valsartan — increases risk of kidney failure, dangerously low blood pressure, and high potassium |
| ACE Inhibitors (e.g., Enalapril, Lisinopril) | Combined use with Valsartan increases risk of low blood pressure, high potassium, and kidney damage — avoid |
| Potassium-sparing diuretics (e.g., Spironolactone) / Potassium supplements | HCTZ causes potassium loss while Valsartan retains potassium — dangerous electrolyte imbalance possible; monitor closely |
| NSAIDs (e.g., Ibuprofen, Diclofenac) | Reduce antihypertensive effect and increase kidney impairment risk — avoid regular combined use |
| Lithium | HCTZ reduces lithium clearance — serious lithium toxicity risk; monitor lithium blood levels closely |
| Antidiabetic medicines (e.g., Metformin, Insulin) | HCTZ raises blood sugar — diabetes medicine doses may need review and adjustment |
| Other antihypertensives | Additive blood pressure lowering — excessive hypotension risk; monitor blood pressure carefully |
| Cholestyramine / Colestipol | Reduce HCTZ absorption — take Co-Extor at least 4 hours before these medicines |
| Simvastatin | Amlodipine increases Simvastatin blood levels — muscle damage risk; statin dose may need reduction |
| Alcohol (شراب) | Enhances blood pressure lowering effect and significantly increases dizziness and fainting risk — avoid completely |
