title: [Pharmacotherapy of the hyperventilation syndrome].
abstract: Hyperventilation may be induced by several organic factors. The HVS-hyperventilation and symptoms such as hypertonia and pain-hypocapnia and disturbance of the acid-base balance--other symptoms--anxiousness--hyperventilation--etc. In the adaptation-hyperventilation and symptoms such as hypertonia and pain,-hupocapnia and disturbance of the acid-base balance-other symptoms--anxiousness--hyperventilation--etc. In the adaptation process one distinguishes the load, the strain and a tension or counterforce (stress). In the cause and effect relationship between the adaptation process and a specific pathology, it is obvious that the strain is the only element capable of eliciting the specific pathology or syndrome. Stress is a compensation for the strain and is therefore beneficial to the organism. The strain is associated with, amongst other things, anxiety and changes in the pyridoxine-L-tryptophan metabolism (nicotinic acid-ribonucleotide synthesis). Stress depends to a large extent on the intact serotonergic transmission in the cerebrum. But serotonin synthesis is critically dependent on the pyridoxine-L-tryptophan metabolism. Benzodiazepines improve the hyperventilation, anxiousness and strain, if these are of the free-floating anxiety type. Tricyclic preparations improve anxiousness in as much as it assumes the character of fear, phobia or an anxiety attack. They are active against strain when that reveals itself as an anxiety attack. Pyridoxine and L-tryptophan as serotonergic agonists, improve the hyperventilation, have a beneficial effect on symptoms such as hypertonia and pain, are effective against anxiousness and anxiety and potentiate the stress. In addition they directly correct the property of strain, i.e. the disturbance of the nicotinicacid-ribonucleotide synthesis. Clomipramine is the most potent serotonergic agonist available. That substance has a favourable effect on hyperventilation, hypertonia and pain, on anxiousness that expresses itself as fear, phobia or an anxiety attack. It favours stress. Further investigation is desirable, in particular of the new serotonergic agonists that have recently been made available or are still to come.
