丁螺環酮(Buspirone;8-[4-[4-(2-pyrimidinyl)-1- piperazinyl]butyl]-8-aza- spiro[4.5]decane-7,9- dione monohydrochloride)是抗焦慮藥的主要成份,一般藥品都採用鹽酸丁螺環酮(Buspirone HCl),是一種白色的結晶體,可溶於水。有兩種形式:錠裝或粉裝。
現時鹽酸丁螺環酮藥物的主要品牌如下: Ansial®; Ansiced®; Anxiron®; Axoren®; Bespar®; Buspar®; Buspimen®; Buspinol®; Buspisal®; Narol®
本藥物的最小劑量為2.5毫克,藥物有5毫克、10毫克、20毫克等不同分量,都可以讓病者把藥片從中間切開,以減低服用量。
丁螺環酮的好處,在於它與傳統的抗焦慮處方,如:苯二氮䓬類藥物(benzodiazepine),令病人依賴的程度相對低得多,而且,亦不會對病者的肝功能構成影響。 Furthermore, it is non-sedating. It is thought to act by interfering with the function of the neurotransmitter serotonin in the brain, particularly by serving as a 5-HT1A receptor partial agonist. 本藥物由Bristol-Myers Squibb公司開發,並於1986年取得美國食物及藥品管理局的許可。本藥品的專利於2001年完結,但現時香港的公立醫院仍然會以原廠藥處方。
No effect on GABA-receptors; partial agonist at 5-HT1A receptors.
Buspirone should be taken in moderation; an increase in blood pressure is among the side effects the medicine can have.
It is also useful as an augmenting agent, for the treatment of depression, when added to SSRIs (selective serotonin reuptake inhibitors).
