Combined reuptake inhibitors and receptor blockers are found in dual action anti depressants. People who suffer from depression suffer from feelings of extreme sadness, hopelessness, guilt and worthlessness. They lose interest in things that previously held their interest, and some even contemplate suicide. These are all related to the mood they are in, which is directly related to their brain chemistry.

The brain produces chemicals called neurotransmitters which send signals from brain cell to brain cell. Two of these neurotransmitters, serotonin and norepinephrine, have been linked with depression. The longer serotonin and norepinephrine stay in the brain, the better the patients’ moods. If a patient is in a good mood, the symptoms of depression are alleviated.

Combined reuptake inhibitors and receptor blockers keep the serotonin and norepinephrine circulating in the brain for as long as possible before being reabsorbed. It is a very effective treatment, but it has several side effects. People who take dual action anti depressants can experience dry mouth, dizziness, drowsiness, lightheadedness, nervousness and nausea. Other side effects include, constipation, a feeling of weakness, problems with vision, feelings of confusion and frequent headaches.
