More than half of people with bipolar disorder take second-generation/atypical antipsychotics on a regular basis to control mood. While effective, there is always a risk of adverse side effects. The list for antipsychotics is long, including dizziness, gastrointestinal distress, weight gain, sleepiness and seizures. The benefits generally outweigh the risks, but side effects are often listed as the main reason patients stop taking medication. However, one atypical antipsychotic seems to have advantages over others- aripiprazole (brand name- Abilify).
Atypical antipsychotics are effective at treating mania in bipolar disorder. They can also
The problem with atypical antipsychotics is most of them come with side effects that prove intolerable for some patients, who may then discontinue medication without the guidance of a physician. Lack of efficacy is also cited as a reason patients quit taking medications. Some drugs, like olanzapine (Zyprexa), quetiapine (Seroquel) and risperidone (Risperdal) are infamous for causing these problems.
If so many bipolar disorder medications are causing problems, is there an alternative?
Researchers led by Dr. Young Sup Woo at the Catholic University of Korea
The researchers found that aripiprazole does have some benefits over other atypical antipsychotics.
-Higher tolerabilityAn average of 20-60% of patients
-Higher remission ratesRemission is difficult to achieve in bipolar disorder. Medication only increases the chances for remission by 20-40%, so finding the most effective medication is imperative. When patients in Dr. Young Sup Woos study were switched to aripiprazole (Abilify), researchers noted a significant decrease in depressive symptoms. At the beginning of the study, only 7% of participants were considered in remission. At the end of
-Lower rate of adverse metabolic effectsMore than half of people gain weightordevelop high cholesterol or metabolic syndrome when taking atypical antipsychotics. Patients average a weight gain of 20-35 pounds in the first year. Olanzapine (Zyprexa) causes the most weight gain, but quetiapine (Seroquel) and risperidone (Risperdal) also cause significant metabolic changes.
With aripiprazole (Abilify), Dr. Young Sup Woo found that cholesterol
There are limits to the benefits demonstrated in this study. First, the number of participants was relatively low for a study on bipolar disorder. Second, in regards to cholesterol and abdominal obesity, patients exercise and diet routines were not monitored.
Most importantly, not everyone responds to every drug the same way. Thats why there are so many available on the market. While aripiprazole (Abilify) may be a better choice for some, it can still produce adverse effects or prove ineffective for others. Its important for patients to work closely with a psychiatrist to determine which medications and dosages are right for their situation.
