The neuroleptic effect and tolerability of roxindole (EMD 49,980), an agonist of the dopamine-D2 autoreceptor, was studied during a 4 week treatment period in 7 patients with paranoid-hallucinatory schizophrenia (ICD-9: 295.3). In patients with a daily dosage of up to 4.5 mg/day, there was no improvement as measured with the total score of the BPRS scale. In contrast, patients with a daily dosage of up to 30 mg/day showed a slight improvement, especially in items associated with negative symptoms. In 3 patients there were slight adverse events (dizziness, hypersalivation, hypotonia, nausea/vomiting, miction disturbance) which were probably connected with the intake of roxindole.

EMD 23,448 was examined in tests of dopaminergic function and was found to be an atypical dopamine (DA) agonist. EMD 23,448 was a weak or inactive DA agonist when examined in tests of normal postsynaptic DA receptor function: production of stereotypy in the rat (ED50 greater than 5.0 mg/kg i.p.); production of emesis in beagles (minimum effective dose = 81 micrograms/kg i.v.); and, enhanced locomotor activity of the mouse (no excitation in doses less than or equal to 50 mg/i.p.). Moreover, EMD 23,448 was relatively weak in competing for [3H]-apomorphine binding to rat striatal membranes (Ki, 205 nM). On the other hand, this indolyl-3-butylamine did activate supersensitive postsynaptic DA receptors. Specifically, it elicited contralateral turning in rats with a unilateral 6-hydroxydopamine lesion of the substantia nigra (ED50 value = 0.9 mg/kg) and did elicit stereotypy in rats given chronic daily haloperidol treatments. EMD 23,448 also exerted pharmacological effects in tests designed to measure activation of dopamine autoreceptors. It inhibited the gamma-butyrolactone-induced increase in striatal dopa levels (ED50 = 1 mg/kg i.p.) and produced a dose-related fall in the locomotor activity of the mouse. The results are discussed and contrasted with data derived for apomorphine and the putatively selective autoreceptor agonist (+/-)-3-PPP.

A 33-year-old man was admitted for general malaise and vomiting. An electrocardiogram showed a complete atrioventricular block and an echocardiogram showed right atrial dilatation and normal wall motion of left ventricle (LV). Gene analysis showed nonsense mutation in the STA gene, which codes for emerin, and Emery-Dreifuss muscular dystrophy was diagnosed. An endomyocardial biopsy of right ventricle showed mild hypertrophy of myocytes. Myocardial scintigraphic studies with Tc-99m methoxyisobutylisonitrile (MIBI) and I-123-betamethyl-p-iodophenylpentadecanoic acid (BMIPP) scintigrams showed no abnormalities. In contrast, I-123 metaiodobenzylguanidine (MIBG) scintigrams showed a diffuse and severe decrease in accumulation of MIBG in the heart. Six months later, his LV wall motion on echocardiograms developed diffuse hypokinesis. These results suggest that the abnormality on I-123 MIBG myocardial scintigrams may predict LV dysfunction in Emery-Dreifuss muscular dystrophy.
