1. What Amdova is and what it is used for?
Amdova®
is a combination product containing Amlodipine Besilate BP equivalent
to 5 mg Amlodipine, a calcium channel blocker and Atorvastatin calcium
INN equivalent to 10 mg Atorvastatin, a statin (HMG-CoA reductase
inhibitor). 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. Atorvastatin
calcium is a synthetic lipid-lowering agent. It is an inhibitor of
3-hydroxy-3-methyl-glutaryl-coenzyme A (HMG-CoA). This enzyme catalyzes
the conversion of HMG-CoA to mevatonate, an early and rate limiting step
in the synthesis of cholesterol.
Patients in whom treatment with Amlodipine and Atorvastatin is appropriate at the dose presented, which include hypertension, chronic stable angina, an adjunct to diet for hypercholesterolemia and in hypertensive patient with multiple risk factors for CHD to reduce the risk of non fatal MI and non fatal stroke.
2. Before you take Amdova
Do not take this medicine and tell your doctor if:
Amlodipine is contraindicated in patients with known hypersensitivity
to Amlodipine. Atorvastatin is contraindicated in hypersensitivity to
any component of this medication. Active liver disease or unexplained
persistent elevations of serum transaminases exceeding three times the
upper limit of normal. Do not take this medicine if the above applies to
you. If you are not sure, talk to your doctor before taking Amdova.
Take special care with Amdova
Since
the vasodilatation induced by Amlodipine is gradual in onset, acute
hypotension has rarely been reported after oral administration of
Amlodipine. Nonetheless, caution should be exercised when administering
Amlodipine as with any other peripheral vasodilator particularly in
patients with severe aortic stenosis. Use in Patients with Congestive
Heart Failure: Although hemodynamic studies and a controlled trial in
Class-II-III heart failure patients have shown that amlodipine did not
lead to clinical deterioration as measured by exercise tolerance, left
ventricular ejection fraction, and clinical symptoms. In general, all
calcium channel blockers should be used with caution in patients with
heart failure. Rhabdomyolysis with acute renal failure secondary to
myoglobinuria has been reported with other drugs in the statin class.
Atorvastatin may cause an elevation in serum creatine phosphokinase
levels. This should be considered in the differential diagnosis of chest
pain in patients on therapy with Atorvastatin. Uncomplicated myalgia
has been reported in Atorvastatin-treated patients. Atorvastatin therapy
should be discontinued if markedly elevated CPK levels occur or
myopathy is diagnosed or suspected.
Taking other medicines
Caution should be exercised when administering Amlodipine as with any
other peripheral vasodilator particularly in patients with severe aortic
stenosis.
Pregnancy and breast-feeding
Safety in pregnancy has not been established.
3. How to take Amdova?
Amlodipine: The usual initial antihypertensive oral dose is 5 mg once
daily with a maximum dose of 10 mg once daily. Elderly individuals or
patients with hepatic insufficiency may be started on 2.5 mg once daily
dose and this dose may be used when adding Amlodipine to other
antihypertensive therapy. Dosage should be adjusted according to each
patient's need. The recommended dose for chronic stable or vasospastic
angina is 5-10 mg, with the lower dose suggested in the elderly and in
patients with hepatic insufficiency.
Atorvastatin: Adults: The
patient should be placed on a standard cholesterol-lowering diet before
receiving Atorvastatin and should continue on this diet during treatment
with Atorvastatin Hypercholesterolemia (Heterozygous Familial and
Nonfamilial) and Mixed Dyslipidemia (Fredrickson Types IIa and IIb): The
recommended starting dose of Atorvastatin is 10 mg daily. The dosage
range is 10 to 80 mg once daily. Atorvastatin can be administered as a
single dose at any time of the day with or without food. Homozygous
Familial Hypercholesterolemia: The dosage of Atorvastatin in patients
with homozygous FH is 10 to 80 mg daily. Patients with renal
insufficiency: Renal disease has no influence on the plasma
concentrations or lipid effects of Atorvastatin; thus no adjustment of
dose is required. Hemodialysis is not expected to significantly enhance
the clearance of Atorvastatin since the drug is extensively bound to
plasma proteins. Patients with hepatic dysfunction: In patients with
moderate to severe hepatic dysfunction, the therapeutic response to
Atorvastatin is unaffected but exposure to the drug is greatly
increased.
If you take more Amdova than you should
In humans, experience with intentional overdosage of Amlodipine &
Atorvastatin is limited. If massive overdosage occurs, active cardiac
and respiratory monitoring should be instituted. Frequent blood pressure
measurements are essential.
If you forget to take Amdova
If you forget to take a dose, take it as soon as you remember it.
However, if it is nearly time for the next dose, skip the missed dose.
Do not take a double dose to make up for a forgotten dose
If you stop taking Amdova
Do not stop taking this medicine without talking to your doctor. You
should not stop taking Amdova just because you feel better. This is
because the problem may come back or get worse again.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
4. Possible side effects
Like all medicines, Amdova can cause side effects, although not everybody gets them.
Amlodipine: General: Since the vasodilatation induced by Amlodipine is
gradual in onset, acute hypotension has rarely been reported after oral
administration of Amlodipine. Nonetheless, caution should be exercised
when administering Amlodipine as with any other peripheral vasodilator
particularly in patients with severe aortic stenosis. Use in Patients
with Congestive Heart Failure: Although hemodynamic studies and a
controlled trial in Class-II-III heart failure patients have shown that
Amlodipine did not lead to clinical deterioration as measured by
exercise tolerance, left ventricular ejection fraction, and clinical
symptoms. In general, all calcium channel blockers should be used with
caution in patients with heart failure. Beta-blocker Rhabdomyolysis with
acute renal failure secondary to myoglobinuria has been reported with
other drugs in this class. Atorvastatin: Atorvastatin may cause an
elevation in serum creatine phosphokinase levels. This should be
considered in the differential diagnosis of chest pain in patients on
therapy with Atorvastatin. Uncomplicated myalgia has been reported in
Atorvastatin-treated patients. Atorvastatin therapy should be
discontinued if markedly elevated CPK levels occur or myopathy is
diagnosed or suspected. Side effects: Atorvastatin is generally well
tolerated. Adverse effects reported commonly include constipation,
flatulence, dyspepsia, abdominal pain, headache, nausea, myalgia,
diarrhea, asthenia and insomnia.
Tell your doctor if any of
the side effects gets serious or lasts longer than a few days, or if you
notice any side effects not listed in this leaflet
