Anagrelide (Agrylin)

What is Agrylin ?

Anagrelide is a drug used for the treatment of essential thrombocytosis, or overproduction of blood platelets. It also has been used in the treatment of chronic myeloid leukemia. Anagrelide controlled release is in phase III clinical trials by Galena Biopharma for the treatment of essential thrombocytosis.

Agrylin is Uses For?

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.

Medical Condition Before Taking Agrylin?

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.

Treatment with AGRYLIN® Capsules should be initiated under close medical supervision. The recommended starting dosage of AGRYLIN® for adult patients is 0.5 mg qid or 1 mg bid (2 capsules of 0.5 mg twice a day), which should be maintained for at least one week. Starting doses in pediatric patients have ranged from 0.5 mg per day to 0.5 mg qid. As there are limited data on the appropriate starting dose for pediatric patients, an initial dose of 0.5 mg per day is recommended. In both adult and pediatric patients, dosage should then be adjusted to the lowest effective dosage required to reduce and maintain platelet count below 600,000/μL, and ideally to the normal range. The dosage should be increased by not more than 0.5 mg/day in any one week. Maintenance dosing is not expected to be different between adult and pediatric patients. Dosage should not exceed 10 mg/day or 2.5 mg in a single dose.

There are no special requirements for dosing the geriatric population.

There are no special requirements for dosing the geriatric population.

It is recommended that patients with moderate hepatic impairment start anagrelide therapy at a dose of 0.5 mg/day and be maintained for a minimum of one week with careful monitoring of cardiovascular effects. The dosage increment must not exceed more than 0.5 mg/day in any one-week. The potential risks and benefits of anagrelide therapy in a patient with mild or moderate impairment of hepatic function should be assessed before treatment is commenced. Use of anagrelide in patients with severe hepatic impairment has not been studied. Use of anagrelide in patients with severe hepatic impairment is contraindicated.
To monitor the effect of anagrelide and prevent the occurrence of thrombocytopenia, platelet counts should be performed every two days during the first week of treatment and at least weekly thereafter until the maintenance dosage is reached.
Typically, platelet count begins to respond within 7 to 14 days at the proper dosage. The time to complete response, defined as platelet count ≤ 600,000/μL, ranged from 4 to 12 weeks. Most patients will experience an adequate response at a dose of 1.5 to 3.0 mg/day. Patients with known or suspected heart disease, renal insufficiency, or hepatic dysfunction should be monitored closely.
