Anxiety is one of the most common psychiatric pathologies worldwide. It usually causes a feeling of unexplained fear or worry, with physical symptoms such as palpitations and shortness of breath. Fortunately, there are medications such as buspirone, which help control symptoms.

Buspirone is a compound belonging to the group of non-benzodiazepine anxiolytics. It is very useful when treating anxiety disorders and other pathologies. The drug works by altering the concentration of certain substances in the brain, called neurotransmitters.

One of the main advantages of this drug is that it has a different chemical structure from other anxiolytics. In this way, it does not generate drowsiness or affect people’s memory. However, taking buspirone can cause serious side effects.

What is buspirone for?

The drug in question is a partial agonist of serotonin 5-HT1A receptors in the brain, that is, it slightly inhibits them. The action of the compound on these receptors allows the concentration of the neurotransmitter to be regulated throughout the brain.

Buspirone is especially useful in the treatment of generalized anxiety disorder (GAD). GAD is characterized by excessive and difficult-to-control worry about certain events or specific activities. Serotonin activates the brain pathways responsible for these responses.

People should note that the drug should only be used in the treatment of anxiety disorder diagnosed by a psychiatrist. In this way, it is not useful if you want to relieve the stress generated by daily activities.

On the other hand, some studies show that buspirone can also be used in the treatment of other psychiatric and neurological disorders. One of the pathologies that can be treated with the drug is depression, provided it is combined with other drugs.

Possible benefits have been established for the following conditions:

  • Parkinson’s disease.
  • Ataxia.
  • Social phobia.
  • Dementia.
  • Alterations in behavior after a brain injury.
  • Attention deficit disorder.

How is buspirone administered?

Buspirone is only available to be taken orally in tablet form. The dose necessary for the treatment of the different disorders may vary, depending on each particular case. In this sense, the compound is available in tablets ranging from 7.5 milligrams to 30 milligrams.

This anxiolytic should only be used under strict medical prescription and following the instructions provided by the specialist. The tablets should be swallowed whole, without crushing or chewing. Also, intestinal absorption can be delayed with food intake.

The recommended starting dose for treating anxiety in adults is 15 milligrams daily. It should be divided into doses of 7.5 milligrams every 12 hours. The doctor may increase the dose by 5 milligrams every 2 or 3 days to a maximum of 60 milligrams daily.

Specialists recommend taking the tablets every day at the same time for best results. Fortunately, some studies show that buspirone is well tolerated by children and adolescents. In this way, the drug can also be used in the treatment of GAD in these patients, although with lower doses.
