Description
Curator's Comment: description was created based on several sources, including: http://www.rxlist.com/agrylin-drug.htm | https://www.drugs.com/pro/anagrelide.html | https://www.ncbi.nlm.nih.gov/pubmed/20331456

Anagrelide is an orally active quinazinolone derivative that was originally developed as an antiplatelet drug. The drug inhibits cyclic nucleotide phosphodiesterase III (PDEIII) and phopholipase A2, which is thought to cause the side effects of vasodilation, positive inotropism, reduced platelet aggregation. However, significant inhibition of platelet aggregation is observed only at doses of anagrelide higher than those required to reduce platelet count. It is indicated for the treatment of patients with thrombocythemia, secondary to myeloproliferative disorders. Commonly reported side effects of anagrelide include: abdominal pain, dizziness, headache, nausea, and palpitations. Other side effects include: back pain, fever, tachycardia, vomiting, and anorexia. There is a single case report, which suggests that sucralfate may interfere with anagrelide absorption. Anagrelide is an inhibitor of cyclic AMP PDE III. The effects of medicinal products with similar properties such as inotropes milrinone, enoximone, amrinone, olprinone and cilostazol may be exacerbated by anagrelide.

Approved Use

Anagrelide hydrochloride capsules are indicated for the treatment of patients with thrombocythemia, secondary to myeloproliferative disorders, to reduce the elevated platelet count and the risk of thrombosis and to ameliorate associated symptoms including thrombo-hemorrhagic events (see CLINICAL STUDIES, DOSAGE AND ADMINISTRATION).

In Vitro Use Guide
Anagrelide was studied as an inhibitor of PDE fractions I, II and III separated from each other from rabbit heart supernatant. Anagrelide did not inhibit PDE I or II except at a concentration of 10(-4) M where inhibition of 33 and 39%, respectively, was noted. As expected, anagrelide inhibited PDE fraction III with a dose-response curve that was closely similar to that seen in the human platelet preparation. The IC50 for inhibition of the rabbit heart PDE fraction III was 7 x 10(-8) M.
