Panic disorder is a common anxiety disorder which can have serious effects on those who suffer from it. People with panic disorder experience recurrent and unexpected panic attacks which are characterized by increased heart rate, sweating, shaking, and intense fear. During such an panic, sufferers may also experience gastrointestinal discomfort or diarrhea. Panic disorder can occur with or without agoraphobia, which is the fear of being in environments from which escape is difficult. Comorbid conditions such as depression, other anxiety disorders, and risk of suicide is increased in those with panic disorder. It causes people to avoid situations in which they fear a panic attack may occur, thus severely limiting their social opportunities, work performance, and overall quality of life.
Currently, the most common treatments for panic disorder include cognitive behavioral therapy, SSRIs, SNRIs, and tricyclic antidepressants. However, for those who wish to avoid unwanted side effects from pharmaceutical drugs, inositol has been shown to be an effective method of treatment for panic disorder. Inositol is an isomer of glucose and a B vitamin which naturally occurs within a normal diet., Inositol is an important part of the phosphatidyl-inositol cycle. This is a second messenger system used by some norepinephrine and serotonin receptors.  Research seems to indicate that this molecule may be able to reduce the frequency and severity of panic attacks.
Benjamin et. al. conducted a double-blind, placebo controlled crossover study to assess the efficacy of inositol. They studied 21 subjects who had a DSM-III-R diagnosis of panic disorder. They found that the people who took 12 grams of inositol had more improvement in the severity and frequency of panic attacks, as well as improved feelings of phobia. Other double blind placebo controlled studies have found inositol to be more effective than placebo, and one has found it to be comparable to the SSRI fluvoxamine!, By using naturally occurring molecules found in the diet, it is possible to reduce anxiety and improve the quality of life for those with panic disorder.
