Contents of the pack
Lantanon belongs to a group of medicines called antidepressants. Lantanon relieves the depressed mood that causes depression. Depression is an emotional disorder. During depression, changes occur in the brain: brain nerve cells communicate with each other through chemical substances, and in depression, the normal amount of these substances is lower. Antidepressants can correct these deficiencies and restore normal brain function. In general, improvement is experienced 2-4 weeks after treatment.
