Tasigna (Nilotinib Capsules) Tasigna (nilotinib hydrochloride monohydrate) is used to treat and keep the CML (Chronic Myeloid Leukemia) under control. The leukemia is also known as the blood disease. It is a sanguine condition defined by the pathological growth of the leucocytes and the apparition of some immature leucocytes. The myeloid leukemia is the form of leukemia described by the abnormal apparition of myelocytes in the blood. The acute form of this disease is the most common form of leukemia in adults. Its chronic form has a 14% rapport. The CML symptoms differ, according to the evolution stage of the disease. In the early stage, the patients might present appetite loss, weight loss, tiredness, fever, excessive sweat or abdominal pains in the left side. As the disease evolves, the patients complain about respiratory difficulties, joint pains, infections and frequent bleeding episodes. Tasigna (nilotinib hydrochloride monohydrate) is FDA accepted since 2007. It may be used in associated therapies, if the CML is too severe. It initially stops the cancer evolution, while other specific techniques deal with the problematic cells. The medication cannot be taken without a prescription. Administration The optimal dosage of Tasigna (nilotinib hydrochloride monohydrate) is 300mg. It is given twice a day, at every 12 hours.
