Buspirone a controlled substance
Is BuSpar (Buspirone) A Controlled Substance?
BuSpar is an antianxiety medication that is not considered a controlled substance and may be a safer alternative to Xanax for some people. However, BuSpar can still be dangerous in high doses, especially when mixed with other substances like alcohol.
BuSpar is a prescription medication that is often used to treat generalized anxiety disorder and panic disorder.
BuSpar has been discontinued as a brand name because there are so many generic versions of buspirone hydrochloride (buspirone HCL) currently available.
Buspirone has been found to be effective in the short-term treatment of anxiety and symptoms of anxiety.
It is often prescribed to a person in addition to certain antidepressants as a way of assisting them through especially stressful periods of time.
While BuSpar shares similarities with drugs like Xanax (alprazolam) and Valium (diazepam) in what it treats and potential side effects, it is not considered a narcotic or controlled substance.
Why BuSpar Is Not Considered A Controlled Substance
BuSpar is not a controlled substance because it is generally considered safe and non-addictive, unlike other drugs which have the same effects.
The biggest dangers with buspirone involve drug interactions.
Non-Habit-Forming
There is no current evidence to suggest that BuSpar is addictive or that people taking it will build up a tolerance to it.
People may, however, experience mild withdrawal symptoms when going off of it, which signals a buspirone dependence.
Less Sedative Properties Than Drugs Like Xanax
The effects of BuSpar, in general ,are similar to Xanax but more mild, including the sedative effects of the drug.
A high dose of buspirone will increase these sedative effects, but there has never been a recorded instance of someone overdosing on buspirone alone.
Works On Serotonin Receptors
Buspirone is considered safer than Xanax because it works on serotonin receptors as opposed to gamma-amino butyric acid (GABA) receptors.
GABA is a type of key neurotransmitter in the brain that impairs motor neurons and thus neuronal activity.
When these neurotransmitters are damaged over time with extended buspirone Xanax use, it can be detrimental to a person’s brain health.
What Drug Class Is Buspirone?
Buspirone is considered a non-benzodiazepine antianxiety agent. It can be referred to as an anxiolytic, or, a drug that is prescribed for treating anxiety.
Buspirone is usually not prescribed to someone as a first attempt at treating anxiety, and is more often prescribed only after someone has experienced adverse effects from a drug like Xanax.
How Buspar Works In The Body
While BuSpar works mostly by acting on serotonin neurotransmitters in the brain, there is also evidence to suggest that it works on dopamine neurotransmitters as well.
Serotonin and dopamine are both neurotransmitters that carry responsibility for a person’s mood and overall levels of happiness and pleasure.
One of the possible more serious side effects of buspirone is the development of a condition called serotonin syndrome.
This occurs when too much serotonin builds up in a person’s body and can be life-threatening if left untreated.
How Does Buspar Make You Feel?
As BuSpar is designed to treat anxiety disorders, it tends to make a person feel relaxed in order to combat their anxiety.
It can also make a person feel sleepy and tired, and even a little euphoric in some cases.
Common side effects of BuSpar include:
- nausea
- drowsiness
- headaches
- impairment
- lightheadedness
- slurred speech
- confusion
- chest pain
- weight gain
People may also experience withdrawal symptoms when going off BuSpar, but these are generally mild and can be avoided by tapering off the drug per healthcare provider instructions.
Is Buspar Dangerous?
BuSpar is not dangerous when taken as directed for a prescription drug. However, BuSpar can become dangerous when taken in high doses or when mixed with other substances, such as alcohol.
Grapefruit juice should be avoided while taking buspirone. Breastfeeding mothers should also avoid taking buspirone.
Buspirone can raise a person’s blood pressure to dangerous levels when combined with a type of drug known as monoamine oxidase inhibitors (MAOIs).
Drugs that may have potential interactions with buspirone include:
- erythromycin (a type of antibiotic)
- diltiazem (used for treating angina)
- haloperidol (used for treating mood disorders)
- itraconazole (an antifungal medication)
- nefazodone (a type of antidepressant)
- rifampin (a type of antibiotic)
- fluoxetine (a type of antidepressant)
- phenelzine (a type of antidepressant)
It is always important to be aware of any dangerous drug interactions and to follow the medical advice and directions of a healthcare professional.

Rec. Included in preparations: list Pharmacological actionAnxiolytic agent, azaspirodecanedione derivative. The mechanism of action has not been definitively established. According to pharmacological properties, it does not apply to benzodiazepines or barbiturates. It has a selective anxiolytic effect. It does not have anticonvulsant activity, does not have a muscle relaxant effect. It does not have a pronounced sedative effect, especially at low doses. High affinity for serotonin 5-HT 1A receptors in dorsal raphe neurons and moderate affinity for dopamine D 2 receptors in the brain. Buspirone does not have a pronounced affinity for benzodiazepine receptors, it does not affect the binding of GABA. Unlike benzodiazepines, the level of spontaneous excitation of noradrenergic cells in the bluish locus (locus ceruleus) increases rather than decreases under the action of buspirone. Buspirone is not believed to cause tolerance, physical or psychological dependence. Pharmacokinetics After oral administration, it is rapidly absorbed from the gastrointestinal tract, Cmax max in blood plasma is reached after 40-90 minutes. Bioavailability is low due to the pronounced effect during the "first pass" through the liver. When taken with food, it is possible to increase bioavailability due to impaired absorption of buspirone from the gastrointestinal tract and, therefore, a decrease in presystemic clearance. Plasma protein binding of buspirone is about 95%. It undergoes intensive metabolism in the liver with the participation of the CYP3A4 isoenzyme. As a result of hydroxylation, several inactive metabolites are formed, oxidative dealkylation leads to the formation of 1-(2-pyrimidinyl)-piperazine, which has anxiolytic activity. Indications of the active substance BUSPIRONTreatment of anxiety disorders or temporary relief of symptoms of anxiety. Open list of ICD-10 codes
Dosage regimen Inside adults at the beginning of treatment - 5 mg 3 times / day. If necessary, the dose is increased by 5 mg / day every 2-3 days until the desired effect is achieved. Side effectsPossible: dizziness, headache, restlessness syndrome. Rare: blurred vision, decreased ability to concentrate, dry mouth, myalgia, muscle spasms, muscle cramps and rigidity, tinnitus, sleep disturbance, nightmares, general weakness, dyspepsia, chest pain, depression , tachycardia, paresthesia, sore throat, fever. Contraindications for useSevere renal impairment, severe hepatic impairment, hypersensitivity to buspirone. Pregnancy and lactationBuspirone should be avoided during pregnancy and lactation. Use in hepatic impairmentContraindicated in severe hepatic impairment. Use in impaired renal functionContraindicated in severe renal impairment. Use in childrenThe safety and efficacy of buspirone in children and adolescents under 18 years of age have not been established. Precautions Buspirone is not used to treat anxiety and reduce tension associated with the stresses of everyday life. Should not be used in patients with epilepsy or a history of a tendency to develop seizures. Use with caution in patients with hepatic and/or renal impairment. Patients with drug abuse or a history of drug dependence should be closely monitored during treatment to detect the development of buspirone tolerance or dependence. Controlled studies have shown that buspirone is not effective for long-term (more than 3-4 weeks) treatment of anxiety. However, when used for several months, no side effects were detected. If buspirone is used for a long time, then its effectiveness should be checked at regular intervals. During the period of treatment, the patient should refrain from activities associated with the need for concentration and high speed of psychomotor reactions. The safety and efficacy of buspirone in children and adolescents under 18 years of age have not been established. Drug interactions Buspirone is metabolized in the liver with the participation of the CYP3A4 isoenzyme and, apparently, can interact with drugs that are inhibitors or inducers of this isoenzyme. |
