1.Differences in the lipolytic and cyclic AMP accumulative action of noradrenaline-theophylline and norephedrine-theophylline.
Nencini P Arzneimittelforschung. 1980;30(7):1080-2.
The action of theophylline derivatives (-)-7-2-(2-hydroxy-1-methyl-2-phenyl-ethylamino)-ethyl-theophyl-line (cafedrine) and 7-2-2-(3,4-dihydroxy-phenyl-2-hydroxy-ethylamino)-ethyl-theophylline (theodrenaline) on free fatty acids (FFA) levels in rat blood serum and on cyclic AMP (cAMP) accumulation and FFA mobilization in isolated fat cells has been studied and compared to the action of a noradrenaline plus aminophylline mixture (NAA). A significant in vivo increase of FFA appeared 15 min after NAT and 90 min after NET i.p. administration. NAA was active at both times. Unlike NET, NAT stimulated in vitro FFA mobilization and cAMP accumulation: NAA action was however stronger. NAT-mediated cAMP accumulation, but not that which was NAA-induced, was totally inhibited by timolol. Our results suggest the existence of a beta-adrenergic mechanism for NAT and a tyraminic mechanism for NET. A theophyllinic action dos not seem to apply to either drug.
2.[Cerebral infarction in an adolescent girl following an overdose of paroxetine and caffedrine combined with theodrenaline].

Selective serotonin reuptake inhibitors (SSRI) have demonstrated to be effective, well tolerated and relatively safe drugs in cases of overdosage. However, and related to the potentiation of the serotonergic transmission elicited by them, these drugs have been associated by some authors with the possibility of causing vascular complications. Serotonin is a vasoactive substance with complex actions on vessel wall as a result of its interaction with specific receptors existing at this level. We present the case of an adolescent girl who suffered a cerebral infarction after consuming a toxic dose of paroxetine and two other products, one of them containing caffedrine and theodrenaline, and the other one a phlebotonic agent. In connection with the possible pathophysiological mecanism the implied products as well as the serotonergic vascular receptors are briefly reviewed. Finally, a reference is made to Calls syndrome as a possible entity related to the unfortunate event suffered by the patient. As a conclusion risks of the combined pharmacotherapy, especially in cases of overdosage and in child and adolescent populations, are underlined.

Background:; Intraoperative hypotension is a common problem and direct or indirect sympathomimetic drugs are frequently needed to stabilize blood pressure. Akrinor;TM; consists of the direct and the indirect sympathomimetic noradrenaline and norephedrine. Both substances are covalently bound to the phosphodiesterase (PDE) inhibitor theophylline, yielding theodrenaline and cafedrine, respectively. We investigated pharmacodynamic effects of Akrinor;TM; and its constituents on contractile force and tension in human atrial trabeculae and internal A. mammaria rings. ;Methods:; Isometric contractions were measured in human atrial trabeculae at 1 Hz and 37°C. CGP 20712A and ICI 118,551 were used to elaborate β;1;- and β;2;-adrenoceptor (AR) subtypes involved and phenoxybenzamine to estimate indirect sympathomimetic action. PDE-inhibition was measured as a potentiation of force increase upon direct activation of adenylyl cyclase by forskolin. Human A. mammaria preparations were used to estimate intrinsic vasoconstriction and impact on the noradrenaline-induced vasoconstriction. ;Results:; Clinically relevant concentrations of Akrinor;TM; (4.2-420 mg/l) robustly increased force in human atrial trabeculae (EC;50; 41 ± 3 mg/l).
