Cautions
Caution in heart disease, renal impairment, mild-moderate hepatic impairment
Torsades de pointes and ventricular tachycardia reported; obtain pretreatment cardiovascular exam, including EKG, in all patients
Hepatic impairment increases anagrelide exposure and could increase risk of QTc prolongation; monitor patients with hepatic impairment for QTc prolongation and other cardiovascular adverse reactions
Increases QTc interval and heart rate in healthy volunteers; should not be used in patients with known risk factors for QT interval prolongation, such as congenital long QT syndrome, a known history of acquired QTc prolongation, medicinal products that can prolong QTc interval and hypokalemia
In patients with cardiac disease, use only when benefits outweigh risks
In patients with heart failure, bradyarrhythmias, or electrolyte abnormalities, consider periodic ECG monitoring
Orthostatic hypotension reported with higher doses; minimal BP changes observed following 2 mg/dose
Coadministration with aspirin increases risk for major hemorrhagic event
Cases of pulmonary hypertension reported; evaluate patients for signs and symptoms of underlying cardiopulmonary disease prior to initiating and during anagrelide therapy
Interstitial lung diseases (including allergic alveolitis, eosinophilic pneumonia and interstitial pneumonitis) reported to be associated with use of anagrelide in post-marketing reports; most cases presented with progressive dyspnea with lung infiltrations; time of onset ranged from 1 week to several years after initiating anagrelide; discontinue anagrelide if it occurs and evaluate; symptoms may improve after discontinuation
Monitor platelets, Hgb, WBC, LFTs, Cr, BUN for at least first 2 weeks
May induce highoutput heart failure by PDE4 inhibition (may be reversible upon discontinuation)
Pregnancy & Lactation
Pregnancy
Available data from case reports in pregnant women have not identified drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes; in animal embryo-fetal studies, delayed fetal development (delayed skeletal ossification and reduced body weight) was observed in rats administered anagrelide hydrochloride during organogenesis at doses approximately 97 times the maximum clinical dose (10 mg/day) based on body surface area; there are adverse effects on maternal and fetal outcomes associated with thrombocythemia in pregnancy
Thrombotic events, such as stroke, deep vein thrombosis, or myocardial infarction, can be complications of thrombocythemia; thrombocythemia in pregnancy is associated with an increased risk for miscarriage, stillbirth, and other maternal outcomes, such as preeclampsia
Animal data
- In a pre- and post-natal study conducted in female rats, anagrelide hydrochloride administered at oral doses of 60 mg/kg/day (58 times the maximum clinical dose based on body surface area) or higher during organogenesis through lactation produced delay or blockage of parturition, deaths of non-delivering pregnant dams and their fully developed fetuses, and increased mortality in the pups born
Infertility
- Based on findings from animal studies, therapy may impair female fertility
Lactation
There is no information regarding presence of drug in human milk, effect on breastfed child, or on milk production; the drug or its metabolites have been detected in milk of lactating rats; because of potential for serious adverse reactions, including thrombocytopenia, in a breastfed child, advise patients that breastfeeding is not recommended during treatment, and for one week following last dose
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

ANAGRELIDE - ORAL
(an-AG-re-lide)
COMMON BRAND NAME(S): Agrylin
USES: Anagrelide is used to treat a certain blood disorder (thrombocythemia), which is caused by your bone marrow making too many platelets. Platelets are a blood cell that the body uses to form blood clots. Too many platelets can cause problems with your circulation, including unwanted blood clots and bleeding problems. This drug reduces the number of platelets in the bloodstream by blocking their production.
HOW TO USE: This medicine may come with a Patient Information Leaflet. Read it carefully if available. Ask your doctor, nurse, or pharmacist any questions that you may have about this medicine.Take this medication by mouth with or without food, usually 2 or 4 times a day or as directed by your doctor. Children or people with liver problems may start out by taking only 1 dose each day. Your doctor will adjust your dose, usually once a week, to find the best dose for you that keeps your blood counts closer to normal. The dosage is based on your medical condition and response to therapy. You should not take more than 2.5 milligrams in a single dose or more than a total of 10 milligrams in a day.Use this medication regularly in order to get the most benefit from it. To help you remember, take it at the same times each day. Keep taking this medication even if you feel well. People with high platelets may not feel sick. Do not stop taking this medication without consulting your doctor. Stopping anagrelide will cause your platelets to go back up.Your doctor will check your blood counts regularly to monitor your progress and adjust your dose.
SIDE EFFECTS: Headache, diarrhea, weakness, nausea, gas, loss of appetite, and dizziness may occur. If any of these effects persist or worsen, contact your doctor or pharmacist promptly.To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor right away if you have any serious side effects, including: unusual bleeding/bruising, black stools, swelling of the ankles/feet, rapid/difficult breathing, stomach/abdominal pain, unusual tiredness, signs of kidney problems (such as change in the amount of urine, pink/bloody urine), vomit that looks like coffee grounds.Get medical help right away if you have any very serious side effects, including: chest/jaw/left arm pain, confusion/mental changes, severe dizziness, fainting, fast/irregular/pounding heartbeat, seizures, trouble speaking, vision changes, weakness on one side of the body.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.
PRECAUTIONS: Before taking anagrelide, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: heart problems (e.g., heart attack, irregular heartbeat), lung problems, kidney problems, liver problems.This drug may make you dizzy. Alcohol or marijuana (cannabis) can make you more dizzy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).Anagrelide may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using anagrelide, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using anagrelide safely.Before having surgery, tell your doctor or dentist that you are using this medication.Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above).During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.It is unknown if this drug passes into breast milk. Because of the possible risk to the infant, breast-feeding is not recommended while using this medication and for 1 week after stopping this medication. Consult your doctor before breast-feeding.
DRUG INTERACTIONS: Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.Some products that may interact with this drug include: other drugs that can cause bleeding/bruising (including antiplatelet drugs such as clopidogrel, "blood thinners" such as warfarin/enoxaparin), sucralfate.Only take aspirin if your doctor approves of it. Aspirin can increase the risk of bleeding when used with anagrelide, especially if you already have a high risk for bleeding. However, if your doctor has directed you to take low-dose aspirin to prevent blood clots, or for heart attack or stroke prevention (usually 81-162 milligrams a day), you should continue taking it unless your doctor instructs you otherwise. Discuss the risks and benefits with your doctor or pharmacist.Many drugs besides anagrelide may affect the heart rhythm (QT prolongation), including amiodarone, chloroquine, clarithromycin, disopyramide, haloperidol, methadone, moxifloxacin, pimozide, procainamide, among others.
OVERDOSE: If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222. Canada residents can call a provincial poison control center. Symptoms of overdose may include: unusual bleeding/bruising, fast heartbeat, vomiting.
NOTES: Do not share this medication with others.Laboratory and/or medical tests (such as heart exam, EKG, complete blood counts, kidney and liver function tests) should be performed before you start treatment, periodically to monitor your progress, or to check for side effects.
