Hydroxyurea: Hydroxyurea inhibits DNA synthesis by inhibition of ribonucleotide diphosphate reductase and is a well-known drug used for the treatment of a number of tumor types including head and neck tumors and chronic myelogenous leukemia. It has also been used as an adjuvant for antiretroviral treatment for patients with HIV and as a treatment for polycythemia vera, essential thrombocythemia and sickle cell disease.

Verapamil: Verapamil is another commonly used medication. It is used for the treatment of angina, hypertension, supraventricular arrhythmias, and migraine prophylaxis. Dosing with standard verapamil is 80-120 mg pox three times a day but the sustained release form can be given 120-480mg once or twice each day.
