DRUG ABUSE AND DEPENDENCE :
Although preliminary animal and human investigations suggest that buspirone may be significantly devoid of potential for producing physical or psychological dependence, only extensive clinical experie
nce with the drug will provide conclusive evidence. Meanwhile, physicians should carefully evaluate patients for a history of drug abuse and follow such patients closely, observing them for signs of b
uspirone misuse and abuse.

Possible food and drug interactions when taking this medication
In another study in normal volunteers, concomitant administration of buspirone and haloperidol resulted in increased serum haloperidol concentrations. The clinical significance of this finding is not
clear.

Other medical problems
Effects on Cognitive and Motor Performance:
In controlled studies in healthy volunteers, single doses of buspirone up to 20 mg had little effect on most tests of cognitive and psychomotor function
, although performance on a vigilance task was impaired in a dose-related manner. The effect of higher single doses of buspirone on psychomotor performance has not been investigated.
Ten mg
of buspirone given 3 times daily for 7 days to healthy volunteers produced considerable subjective sedation but no significant effect on psychomotor performance (no vigilance tasks were used in this s
tudy). It also caused transient dizziness, especially on standing and walking.

Symptoms of overdose
In clinical pharmacology trials, buspirone up to 400 mg/day was administered to healthy male volunteers. As this dose was approached, the following symptoms were observed in descending order of freque
ncy: drowsiness, ataxia, nausea and vomiting, dizziness, clammy feeling, difficulty thinking, feeling high, rushing sensation, gastric distress, headache, itching, miosis, hypotension, tremor, incoord
ination, insomnia and hallucinations. In a dose ranging study in acute psychotic patients, up to 2400 mg/day was administered. Dizziness, nausea and vomiting were the most common adverse effects. One
patient developed extrapyramidal symptoms at 600 mg/day.

Description
The mechanism of action of BUSPAR is not clearly known. BUSPAR differs from typical benzodiazepines like Vallium or Xanax anti-anxiety medication in that it does not exert anti-seizure or muscle relax
ant effects. It also lacks the prominent sedative effect that is associated with benzodiazepines
In vitro studies have shown that BUSPAR has a high affinity for serotonin receptors (receptors
in the brain that mediate arousal). BUSPAR has no significant affinity for benzodiazepine receptors in the brain.
