Prexaron M Uses, Dosage, Side Effects, Food Interaction and all others data.

Citicoline is a naturally occurring, water-soluble biological compound that is essential intermediate for the synthesis of phosphatidylcholine, a major constituent of the gray matter of brain tissue. Citicoline promotes brain metabolism by enhancing the synthesis of acetylcholine and restoring phospholipid content in the brain. It also elevates brain oxygen consumption and improves brain metabolism. Citicoline seems to increase a brain chemical called phosphatidylcholine. This brain chemical is important for brain function. Citicoline might also decrease brain tissue damage when the brain is injured.

Mecobalamin is the neurologically active form of vitamin B12 and occurs as a water-soluble vitamin in the body. It is a cofactor in the enzyme methionine synthase, which functions to transfer methyl groups for the regeneration of methionine from homocysteine. In anaemia, it increases erythrocyte production by promoting nucleic acid synthesis in the bone marrow and by promoting maturation and division of erythrocytes.

Precaution

In acute and emergency condition, citicoline should be administered. In conjunction with intracranial pressure-relieving drugs or homostatic and treatment eg, hypothermy. If intracranial bleeding continue, avoid giving high-dose citicoline (>500 mg concomitantly), since it may exaggerate blood flow in brain. In case small dose of citicoline (100-500 mg 2-3 times daily) may be needed.

Precaution should be given in patients with hypersensitivity. For patients with disturbance of consciousness in acute stage of cerebral infarction, start of citicoline injection recommended within 2 weeks after apoplectic stroke.
