Fluvoxamine is an antidepressant which functions pharmacologically as a selective serotonin reuptake inhibitor. Though it is in the same class as other SSRI drugs, it is most often used to treat obsessive-compulsive disorder. Fluvoxamine has been in use in clinical practice since 1983 and has a clinical trial database comprised of approximately 35,000 patients. It was launched in the US in December 1994 and in Japan in June 1999. As of the end of 1995, more than 10 million patients worldwide have been treated with fluvoxamine. The exact mechanism of action of fluvoxamine has not been fully determined, but appears to be linked to its inhibition of CNS neuronal uptake of serotonin. Fluvoxamine blocks the reuptake of serotonin at the serotonin reuptake pump of the neuronal membrane, enhancing the actions of serotonin on 5HT1A autoreceptors. In-vitro studies suggest that fluvoxamine is more potent than clomipramine, fluoxetine, and desipramine as a serotonin-reuptake inhibitor. Studies have also demonstrated that fluvoxamine has virtually no affinity for α1- or α2-adrenergic, β-adrenergic, muscarinic, dopamine D2, histamine H1, GABA-benzodiazepine, opiate, 5-HT1, or 5-HT2 receptors. Fluvoxamine is used for management of depression and for Obsessive Compulsive Disorder (OCD). Has also been used in the management of bulimia nervosa. Fluvoxamine is known under the brand names: Faverin, Fevarin, Floxyfral, Dumyrox and Luvox.

RGH-896 (radiprodi) is orally active and selective NMDA NR2B antagonist, a potential therapeutic agent in treatment of neuropathic pain and possibly other chronic pain conditions. It blocks pain signaling without interacting with other NMDA receptor subtypes thus potentially improving therapeutic index and side effect profile. RGH-896 is the first of this group and is currently in early clinical development. Forest and Richter initiated a Phase IIb study in neuropathic pain in the United Stated in the second half of 2006. The drug did not produce significant reductions in patient-reported pain scores for all the dosages tested. Forest says that it and Gedeon Richter will review the findings before making a decision about the further development of radiprodil. In addition to neuropathic pain, the companies intend to investigate various other pain conditions and possibly CNS indications not related to pain. Forest will pay Richter undisclosed upfront and milestone payments in addition to royalties and will have exclusive rights in the U.S. and Canada. The two companies will jointly fund the development program. RGH-896 has patent applications that provide patent protection until at least 2022.

Esmirtazapine (S-(+)mirtazapine or ORG-50081) is an enantiomer of mirtazapine (REMERON®), a high-affinity antagonist at 5-HT2/5-HT3 and H1 receptors, used in the treatment of depression. Esmirtazapine has a shorter plasma half-life than the R(−) enantiomer. Esmirtazapine is preferentially metabolized into an 8-hydroxy glucuronide. Organon was developing esmirtazapine for the treatment of hot flushes (vasomotor symptoms) associated with the menopause and insomnia.
