Dikkat eksikliği hiperaktivite bozukluğu (DEHB) çocukluk çağının en sık görülen psikiyatrik bozukluğu olmasının yanı sıra tedavi edilmediğinde son derece ciddi psikiyatrik, akademik ve sosyal sorunlara yol açabilen ciddi bir psikiyatrik bozukluktur. Yarım asırı aşkın bir süredir DEHB, metilfenidat ve amfetamin gibi stimülan ilaçlarla başarılı bir şekilde tedavi edilmektedir. Klinik araştırmalardaki katılımcıların %20-35’i başlangıçtaki stimülan tedavisine yetersiz yanıt verdiği bildirilmektedir. Bu nedenle DEHB tedavisinde stimülan dışı alternatifler araştırılmış ve stimülan olmayan atomoksetin, klonidin ve guanfasin geliştirilmiştir. Çocuklarda DEHB tedavisi için uzun etkili guanfasinin kullanımı incelenmiş ve hiperaktivite ve dikkat eksikliğinde anlamlı iyileşme saptanmıştır. Bu erken çalışmalar, uzun etkili guanfasinin geliştirilmesini ve 2009 yılında DEHB tedavisinde formülasyonun Amerika Birleşik Devletleri Gıda ve İlaç Dairesi onayı almasını sağlamıştır. Amfetamin veya metilfenidatı tolere etmeyen hastalar, özellikle iştah azalması, uykusuzluk veya taşikardisi olan hastalar için guanfasin uygun bir seçenektir. Bu makale, DEHB için uzun salımlı guanfasin ile ilgili mevcut literatürü gözden geçirmekte ve bu ilacın kimyasal yapısını, dozaj ve uygulamasını, etki mekanizmasını, farmakokinetiğini ve farmakodinamiğini, klinik deneylerdeki etkinliğini, güvenliğini ve tolere edilebilirliğini ve DEHB tedavisindeki rolünü tartışmaktadır.
The Role of Long-acting Guanfasine in the Treatment of Attention Deficit Hyperactivity Disorder
Attention deficit hyperactivity disorder ADHD is a serious psychiatric disorder that can lead to extremely serious psychiatric, academic and social problems if not treated, as well as being the most common psychiatric disorder of childhood. ADHD has been successfully treated with stimulant drugs such as methylphenidate and amphetamines for over half a century. It is reported that 20-35% of participants in clinical trials have an inadequate response to initial stimulant treatment. Therefore, non-stimulant alternatives have been investigated in the treatment of ADHD and non-stimulant atomoxetine, clonidine and guanfacine have been developed. The use of long-acting guanfacine for the treatment of ADHD in children was examined and significant improvement was found in hyperactivity and attention deficit. These early studies led to the development of long-acting guanfacine and, in 2009, the formulation received United States Food and Drug Administration approval for the treatment of ADHD. For patients who do not tolerate amphetamine or methylphenidate, especially those with decreased appetite, insomnia or tachycardia, guanfacine is a suitable option. This article reviews the available literature on extended-release guanfacine for ADHD and discusses its chemical structure, dosage and administration, mechanism of action, pharmacokinetics and pharmacodynamics, efficacy, safety and tolerability in clinical trials, and its role in the treatment of ADHD
