Since the vasodilation induced by amlodipine is gradual in onset, acute hypotension has rarely been reported after oral administration. Nonetheless, caution, as with any other peripheral vasodilator, should be exercised when administering amlodipine, particularly in patients with severe aortic stenosis. If excessive hypotension occurs with Exforge, the patient should be placed in a supine position and, if necessary, given an intravenous infusion of normal saline.
A transient hypotensive response is not a contraindication to further treatment, which usually can be continued without difficulty once the blood pressure has stabilized. Risk Of Myocardial Infarction Or Increased Angina Worsening angina and acute myocardial infarction can develop after starting or increasing the dose of amlodipine, particularly in patients with severe obstructive coronary artery disease.
Impaired Renal Function Changes in renal function including acute renal failure can be caused by drugs that inhibit the renin-angiotensin system and by diuretics. Patients whose renal function may depend in part on the activity of the reninangiotensin system e. Monitor renal function periodically in these patients. Hyperkalemia Drugs that inhibit the renin-angiotensin system can cause hyperkalemia. Monitor serum electrolytes periodically.
Some patients with heart failure have developed increases in potassium with valsartan therapy. These effects are usually minor and transient, and they are more likely to occur in patients with pre-existing renal impairment. Female patients of childbearing age should be told about the consequences of exposure to Exforge during pregnancy.
Discuss treatment options with women planning to become pregnant. Patients should be asked to report pregnancies to their physicians as soon as possible. Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment Of Fertility Amlodipine Rats and mice treated with amlodipine maleate in the diet for up to 2 years, at concentrations calculated to provide daily dosage levels of 0.
Calculations based on a 60 kg patient. Mutagenicity studies conducted with amlodipine maleate revealed no drug-related effects at either the gene or chromosome level.
These doses in mice and rats are about 2. Mutagenicity assays did not reveal any valsartan-related effects at either the gene or chromosome level. These assays included bacterial mutagenicity tests with Salmonella and E. Use In Specific Populations Pregnancy Pregnancy Category D Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death.
Potential neonatal adverse effects include skull hypoplasia, anuria, hypotension, renal failure, and death. When pregnancy is detected, discontinue Exforge as soon as possible. These adverse outcomes are usually associated with use of these drugs in the second and third trimesters of pregnancy.
Most epidemiologic studies examining fetal abnormalities after exposure to antihypertensive use in the first trimester have not distinguished drugs affecting the reninangiotensin system from other antihypertensive agents.
Appropriate management of maternal hypertension during pregnancy is important to optimize outcomes for both mother and fetus. In the unusual case that there is no appropriate alternative to therapy with drugs affecting the renin-angiotensin system for a particular patient, apprise the mother of the potential risk to the fetus.
Perform serial ultrasound examinations to assess the intra-amniotic environment. If oligohydramnios is observed, discontinue Exforge, unless it is considered lifesaving for the mother. Fetal testing may be appropriate, based on the week of pregnancy. Patients and physicians should be aware, however, that oligohydramnios may not appear until after the fetus has sustained irreversible injury. Closely observe infants with histories of in utero exposure to Exforge for hypotension, oliguria , and hyperkalemia [see Use in Specific Populations].
Labor And Delivery The effect of Exforge on labor and delivery has not been studied. Nursing Mothers It is not known whether amlodipine is excreted in human milk. In the absence of this information, it is recommended that nursing be discontinued while amlodipine is administered.
It is not known whether valsartan is excreted in human milk. This will help you get the best results and lower the risk of side effects. Depending on how you respond to the treatment, your doctor may suggest a higher or lower dose. Do not exceed the prescribed dose. If you have any further questions on the use of this medicine, ask your doctor or pharmacist. Then take your next dose at its usual time. However, if it is almost time for your next dose, skip the dose you missed. Do not take a double dose to make up for a forgotten tablet.
Do not stop taking your medicine unless your doctor tells you to. Possible side effects Like all medicines, this medicine can cause side effects, although not everybody gets them.
Some side effects can be serious and need immediate medical attention A few patients have experienced these serious side effects may affect up to 1 in 1, people.
If any of the following happen, tell your doctor straight away: Allergic reaction with symptoms such as rash, itching, swelling of face or lips or tongue, difficulty breathing, low blood pressure feeling of faintness, light-headedness. Uncommon may affect up to 1 in people: Always speak with your doctor or pharmacist about dosages that are right for you. It comes with serious risks if you don't take it as prescribed. Your blood pressure can increase and cause serious side effects.
These include heart failure, kidney problems, vision problems, heart attack, or stroke. Your medication may not work as well and your blood pressure may not be controlled. In order for this drug to work well, a certain amount needs to be in your body at all times. If you take too much: You could have dangerous levels of the drug in your body. Symptoms of an overdose of this drug can include: If your symptoms are severe, call or go to the nearest emergency room right away.
What to do if you miss a dose: Take it as soon as you remember. But if you remember just a few hours before the time for your next dose, only take one dose. If massive overdose should occur, initiate active cardiac and respiratory monitoring.
Frequent blood pressure measurements are essential. Should hypotension occur, cardiovascular support including elevation of the extremities and the judicious administration of fluids should be initiated. If hypotension remains unresponsive to these conservative measures, consider administration of vasopressors such as phenylephrine with attention to circulating volume and urine output.
As amlodipine is highly protein bound, hemodialysis is not likely to be of benefit. Administration of activated charcoal to healthy volunteers immediately or up to two hours after ingestion of amlodipine has been shown to significantly decrease amlodipine absorption. Valsartan Limited data are available related to overdosage in humans. The most likely effect of overdose with valsartan would be peripheral vasodilation, hypotension, and tachycardia; bradycardia could occur from parasympathetic vagal stimulation.
Depressed level of consciousness, circulatory collapse, and shock have been reported. If symptomatic hypotension should occur, supportive treatment should be instituted. Valsartan is not removed from the plasma by hemodialysis. Amlodipine besylate is a white or almost white powder, slightly soluble in water and sparingly soluble in ethanol.
Valsartan is a nonpeptide, orally active, and specific angiotensin II antagonist acting on the AT1 receptor subtype. Valsartan is white or almost white hygroscopic powder, freely soluble in anhydrous ethanol; sparingly soluble in methylene chloride; practically insoluble in water.
Amlodipine and Valsartan tablets, USP are formulated in four strengths for oral administration with a combination of amlodipine besylate, equivalent to 5 mg or 10 mg of amlodipine free-base, with mg, or mg of valsartan providing for the following available combinations: The inactive ingredients for all strengths of the tablets are colloidal silicon dioxide, crospovidone, magnesium stearate and microcrystalline cellulose.
The film coating contains hypromellose, iron oxide yellow, polyethylene glycol, talc and titanium dioxide. Amlodipine and Valsartan - Clinical Pharmacology Mechanism of Action Amlodipine Amlodipine is a dihydropyridine calcium channel blocker that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle. Experimental data suggest that amlodipine binds to both dihydropyridine and nondihydropyridine binding sites.
The contractile processes of cardiac muscle and vascular smooth muscle are dependent upon the movement of extracellular calcium ions into these cells through specific ion channels. Amlodipine inhibits calcium ion influx across cell membranes selectively, with a greater effect on vascular smooth muscle cells than on cardiac muscle cells.
Negative inotropic effects can be detected in vitro but such effects have not been seen in intact animals at therapeutic doses. Serum calcium concentration is not affected by amlodipine. Amlodipine is a peripheral arterial vasodilator that acts directly on vascular smooth muscle to cause a reduction in peripheral vascular resistance and reduction in blood pressure. Angiotensin II is the principal pressor agent of the renin-angiotensin system, with effects that include vasoconstriction, stimulation of synthesis and release of aldosterone, cardiac stimulation, and renal reabsorption of sodium.
Your physician may consider prescribing the two medications separately. Amlodipine Norvasc is available in a 2. You can browse Drugs A-Z for a specific prescription or over-the-counter drug or look up drugs based on your specific condition.

These effects are usually minor and transient, and they are more likely to occur in patients with pre-existing renal impairment. Plasma concentrations correlate with effect in both young and elderly patients. With chronic, once-daily administration, valsartan 160mg amlodipine 10mg, antihypertensive effectiveness is maintained for at least 24 hours. The rate and extent of absorption of valsartan and amlodipine from Exforge are the same as when administered as valsartan tablets. This means that both of these substances help to stop the blood vessels tightening. Never try to catch up by taking two tablets at once. Valsartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT1 receptor in many tissues, such as vascular smooth muscle and the adrenal 160mg. These doses in mice and rats are about 2, valsartan 160mg amlodipine 10mg. This information is not a substitute for medical advice. Valsartan was excreted into the milk of lactating rats; however, animal breast milk drug levels may not accurately reflect human breast milk amlodipine. Alopecia, bullous dermatitis Vascular:
Yellow oblong film-coated tablet with break line, dimension approx. Hepatic Impairment Amlodipine Exposure to amlodipine is increased in patients with hepatic insufficiency [see Clinical Pharmacology Experimental data suggest that amlodipine binds to both dihydropyridine and nondihydropyridine binding sites. These adverse outcomes are usually associated with use of these 160mg in the valsartan and third trimester of pregnancy. Drug information contained herein may be time sensitive. This 10mg help you get the best results and lower the risk of side effects. In the case of severe renal disease, exercise care with dosing of valsartan. Frequent monitoring of trough blood levels valsartan cyclosporine and tacrolimus price of advair 500 50 recommended and adjust the dose when appropriate [see Clinical Pharmacology No dosing recommendations can be provided for patients with severe liver disease. Closely monitor blood pressure, renal function, and electrolytes in patients on Amlodipine and Valsartan tablets and other agents that affect the RAS, valsartan 160mg amlodipine 10mg. Closely observe infants with histories of in utero exposure to Amlodipine and Valsartan tablets for hypotension, oliguria, and hyperkalemia [see Use in Specific Populations 8. Blockade of the angiotensin II receptor inhibits the negative regulatory feedback of amlodipine II on renin amlodipine, but the resulting increased plasma renin activity and angiotensin II circulating levels do not overcome the effect of valsartan on blood pressure. Most 10mg studies examining fetal abnormalities after exposure to antihypertensive use in 160mg first trimester have not distinguished drugs affecting the reninangiotensin system from other antihypertensive agents. Coadministration of inhibitors of the uptake transporter rifampin, cyclosporine or efflux transporter ritonavir may increase the systemic exposure to valsartan. The most likely effect of overdose with valsartan would be peripheral vasodilation, hypotension, and tachycardia ; bradycardia could occur from parasympathetic vagal stimulation, valsartan 160mg amlodipine 10mg.
