Drug Class: Calcium Channel Blocker + Angiotensin Receptor Blocker (ARB) Combination | Form: Oral Tablet | Prescription Status: Prescription Only (Rx) — DRAP Registered
What is Valam 10/160mg Tablet?
Valam 10/160mg is a fixed-dose dual combination tablet containing Amlodipine 10mg and Valsartan 160mg — two proven antihypertensive medicines working through completely different and complementary mechanisms to lower blood pressure more effectively than either medicine alone. Amlodipine relaxes and widens blood vessels by blocking calcium entry into vessel wall muscle cells, while Valsartan blocks angiotensin II — a powerful hormone that narrows blood vessels and raises blood pressure. Together they deliver superior blood pressure control from two separate pathways simultaneously — without the diuretic component, making Valam 10/160mg particularly suitable for patients who require strong dual antihypertensive therapy but do not need or cannot tolerate an added diuretic. It is prescribed for adults with essential hypertension (ہائی بلڈ پریشر) to reduce the long-term risk of heart attack (دل کا دورہ), stroke (فالج), and cardiovascular complications from uncontrolled high blood pressure.
What is Valam 10/160mg Used For?
- Essential hypertension — treatment of high blood pressure in adults not adequately controlled on a single antihypertensive medicine (ہائی بلڈ پریشر)
- Dual antihypertensive therapy — as a convenient single tablet replacing separately taken Amlodipine and Valsartan for improved treatment adherence
- Cardiovascular risk reduction — reducing the long-term risk of stroke, heart attack, and heart failure in hypertensive patients with established cardiovascular risk factors
- Diuretic-free blood pressure control — suitable for patients who experience excessive urination, electrolyte disturbances, or gout with thiazide diuretics
How Does Valam 10/160mg Work?
Amlodipine 10mg — Calcium Channel Blocker: Calcium plays a key role in causing blood vessel wall muscle cells to contract and narrow. Amlodipine blocks the entry of calcium into these cells through specialised voltage-gated channels — causing the muscle cells to relax and the blood vessels to widen. This vasodilation reduces the resistance the heart must pump against — directly and sustainably lowering blood pressure throughout the day. Amlodipine has a long duration of action, providing consistent 24-hour blood pressure control from a single daily dose.
Valsartan 160mg — Angiotensin Receptor Blocker (ARB): The renin-angiotensin-aldosterone system (RAAS) is one of the body's primary blood pressure regulation mechanisms. Angiotensin II — a key hormone in this system — powerfully narrows blood vessels, promotes sodium and water retention, and raises blood pressure. Valsartan selectively blocks the angiotensin II type 1 (AT1) receptor — preventing angiotensin II from exerting its blood pressure-raising effects. This causes blood vessels to relax, reduces fluid retention, lowers blood pressure, and provides long-term protection to the heart and kidneys from the damaging effects of sustained hypertension.
Combined Dual Effect: Amlodipine targets blood vessel resistance through the calcium channel pathway while Valsartan targets the hormonal blood pressure regulation pathway — two distinct and independent mechanisms working simultaneously. This complementary dual action produces greater blood pressure reduction than maximising the dose of either medicine alone — with a more favourable side effect profile than higher single-agent doses.
Dosage and Administration
⚠️ Always take exactly as prescribed by your doctor. Never stop Valam suddenly without medical advice — abrupt discontinuation can cause dangerous rebound hypertension.
| Indication | Usual Adult Dose | Frequency | Maximum Daily Dose |
|---|---|---|---|
| Essential Hypertension | 1 tablet (10/160mg) | Once daily | 1 tablet |
Critical Dosing Rules:
- Valam 10/160mg is typically prescribed after blood pressure has not been adequately controlled on a single antihypertensive medicine — it is not usually a first-line starting treatment
- Blood pressure and kidney function must be monitored regularly throughout treatment
- Elderly patients and those with liver impairment may be more sensitive to blood pressure lowering effects — monitor closely especially in the first weeks of treatment
- If blood pressure remains uncontrolled on Valam 10/160mg, your doctor may add a diuretic component or step up to a triple combination
- Never stop suddenly — always taper 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
- Take at the same time each day — consistent once-daily dosing maintains stable blood pressure control
- 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 |
Who Should NOT Take Valam 10/160mg?
Do not take if you:
- Are allergic to Amlodipine, Valsartan, or any ingredient in the tablet
- Have severe liver disease or biliary cirrhosis
- Have severe kidney disease or are currently on dialysis
- 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
- Have a history of angioedema with any ARB or ACE inhibitor
Always consult your doctor before taking Valam if you have:
- Mild to moderate kidney disease (گردے کی بیماری) — monitor kidney function regularly
- Mild to moderate liver disease — both Amlodipine and Valsartan are liver-metabolised
- Severe aortic or mitral valve stenosis — Amlodipine requires caution in these conditions
- Heart failure — Valsartan requires careful initiation and monitoring under cardiologist supervision
- Low blood volume or dehydration — risk of excessive first-dose blood pressure drop
- Are elderly — increased sensitivity to blood pressure lowering effects and postural hypotension
- Are taking ACE inhibitors or Aliskiren — serious interaction risk with Valsartan
Side Effects
Common Side Effects:
- Ankle swelling (oedema) — Amlodipine related blood vessel dilation; common with calcium channel blockers at 10mg dose
- Dizziness or light-headedness — especially when standing up quickly (postural hypotension)
- Headache — usually mild and improves with continued use
- Flushing or feeling of warmth — Amlodipine related; particularly in the face
- Fatigue or tiredness
- Nausea or mild stomach discomfort — usually temporary
Serious Side Effects — Stop Taking and Seek Medical Help Immediately:
- Severe hypotension — extreme dizziness, fainting, or collapse — particularly after the first dose or during dehydration or illness (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 — stop immediately and seek urgent medical care
- Hyperkalaemia (high potassium) — muscle weakness, irregular heartbeat — Valsartan retains potassium; risk increases with ACE inhibitors or potassium supplements
- Severe allergic reaction — widespread rash, skin blistering or peeling — stop immediately and seek medical attention
- Severe liver reaction — yellowing of skin or eyes (یرقان), dark urine, extreme fatigue — rare but reported with Valsartan; seek immediate medical attention
- Worsening angina or heart attack — rare with Amlodipine initiation in patients with severe obstructive coronary artery disease; seek emergency care immediately
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 | Valsartan retains potassium — additive hyperkalaemia risk; avoid combining unless specifically prescribed with close monitoring |
| NSAIDs (e.g., Ibuprofen, Diclofenac) | Reduce antihypertensive effect of Valsartan and increase kidney impairment risk — avoid regular combined use |
| Cyclosporine / Tacrolimus | Increase Valsartan blood levels — monitor kidney function and blood pressure closely |
| Simvastatin | Amlodipine increases Simvastatin blood levels significantly — muscle damage risk; Simvastatin dose must not exceed 20mg daily when combined |

Frequently Asked Questions (FAQs)
Q: What is the difference between Valam 10/160mg and Valam 5/160mg? The only difference is the Amlodipine dose — 5mg causes significantly less ankle swelling and suits patients starting dual combination therapy or those who could not tolerate the higher 10mg strength.
Q: Can I stop taking Valam 10/160mg once my blood pressure feels normal? Never stop without your doctor's advice — normal readings confirm the medicine is working effectively; stopping suddenly risks dangerous rebound hypertension and significantly raises the risk of stroke and heart attack.
Q: Is Valam 10/160mg safe during pregnancy? No — Valsartan is strictly contraindicated throughout all trimesters of pregnancy due to serious risk of foetal harm; inform your doctor immediately if you become or plan to become pregnant while taking this medicine.
Q: Can Valam 10/160mg be combined with a diuretic if blood pressure is still not controlled? Yes — if blood pressure remains above target on Valam 10/160mg, your doctor may add Hydrochlorothiazide or step up to a triple combination tablet; never add medicines without your doctor's explicit advice.
