Batoprazine (8-(1-piperazinyl)-2H-1-benzopyran-2-one) is a mixed 5-HT1A/1B receptor agonist. Batoprazine has been preclinically studied as an anti-aggressive agent. Development of batoprazine has been discontinued.

Pinaverium, known under the brand name DICETEL, is a spasmolytic agent used for functional gastrointestinal disorders. It is a quaternary ammonium compound that acts as an atypical calcium antagonist to restore normal bowel function. It is shown to relieve GI spasm and pain, transit disturbances and other symptoms related to motility disorders and may be considered as effective first-lline therapy for patients with irritable bowel syndrome (IBS). Pinaverium is also used to help relieve symptoms caused by certain disorders of the gallbladder associated with secretion of bile. Pinaverium bromide is the common ingredient in formulations, mostly as oral tablets. Although it is not a currently approved drug by the FDA, pinaverium is available in over 60 countries including Canada. DICETEL® (pinaverium bromide) is a calcium antagonist which inhibits the calcium influx by blocking the voltage-dependent calcium channel at the smooth muscle cell level. It possesses a high degree of selectivity for the intestinal smooth muscle.

Tedisamil is an antiarrhythmic with additional anti-ischaemic properties, which acts via potassium channel blockade. This drug can be categorised as a class III antiarrhythmic agent due to its effects of action potential and QT interval prolongation in these patients. Although tedisamil has been shown to be an effective anti-ischaemic agent, with Phase III trials for angina pectoris now completed, the company are now pursuing the use of tedisamil for the treatment of atrial fibrillation, for which tedisamil is still in Phase II/III clinical trials. The FDA’s Cardiovascular and Renal Drugs Advisory Committee voted not to recommend approval for Solvay Pharmaceuticals’ investigational anti-arrhythmic drug Pulzium (Tedisamil) and asked the company to give the FDA more information.

Ajmaline, (also known by trade names Gilurytmal, Ritmos, and Aritmina) is an alkaloid found in the root of Rauwolfia serpentina, among other plant sources. It is a class Ia antiarrhythmic agent that apparently acts by changing the shape and threshold of cardiac action potentials. The class I antiarrhythmic agents interfere with the sodium channel. A class IA agent lengthens the action potential (right shift) which brings about improvement in abnormal heart rhythms. This drug in particular has a high affinity for the Nav 1.5 sodium channel. Ajmaline produces potent sodium channel blocking effects and a very short half-life which makes it a very useful drug for acute intravenous treatments. The drug has been very popular in some countries for the treatment of atrial fibrillation in patients with the Wolff–Parkinson–White syndrome and in well tolerated monomorphic ventricular tachycardias. It has also been used for many years as a drug to challenge the conduction system of the heart in cases of bundle branch block and syncope. In these cases, abnormal prolongation of the HV interval has been taken as a proof for infrahisian conduction defects tributary for permanent pacemaker implantation. Ajmaline is used as an antiarrhythmic agent.

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.

Adoprazine (SVL-313) is a full 5-HT1A receptor agonist and full D2/3 receptor antagonist possessing characteristics of an atypical antipsychotic, representing a potential novel treatment for schizophrenia and bipolar disorder. This drug together with some others, e.g. Mazapertine succinate, PF-217830 was discontinued from clinical trials due to either non-optimal pharmacokinetic properties or insufficient therapeutical efficacy.

Pardoprunox is a partial D2/3 dopamine receptor agonist and full 5-HT1A serotonin receptor agonist. Partial D(2/3) dopamine (DA) receptor agonists provide a novel approach to the treatment of the motor symptoms of Parkinson's disease that may avoid common dopaminergic side effects, including dyskinesia and psychosis. Pardoprunox passed phase III clinical trial for the treatment of Parkinson's disease.

Bifeprunox, code name DU-127,090 is an atypical antipsychotic agent, which combines minimal D2 receptor agonism with 5-HT receptor agonism. Bifeprunox was in phase III of clinical trials for the treatment of schizophrenia, Bipolar Depression and in phase I for Parkinson's disease, but these studies were discontinued because efficacy data did not support pursuing the existing development strategy of stabilization of non-acute patients with schizophrenia.

Eltoprazine, a 5-HT1A/B receptor partial agonist, was created by Duphar in the 1980s (as DU-28853) and was subsequently developed by Solvay to treat pathological aggression. This drug is in clinical development for the treatment of Parkinson's disease levodopa-induced dyskinesia (PD-LID), Alzheimer's aggression and adult attention deficit hyperactivity disorder (adult ADHD). In addition, was shown, that the drug could be useful for normalizing prefrontal cognitive abilities, reducing aggression and impulsivity, and improving cognitive function in schizophrenia.
