Definitions
- the present application relates to the use of helium-oxygen gas mixtures for the treatment and / or prophylaxis of primary and secondary forms of pulmonary hypertension (PH) and the combination of drugs with helium-oxygen gas mixtures, wherein the gas mixtures as carrier gases to improve the introduction of a Medicament for the treatment and / or prophylaxis of pulmonary hypertension serve.
- PH pulmonary hypertension
- PAP Primary pulmonary arterial hypertension
- mPAP pulmonary arterial mean pressure
- the pathophysiology of pulmonary arterial hypertension is characterized by vasoconstriction and remodeling of the pulmonary vessels.
- chronic PAH the vascular musculature increases in size, followed by a slow remodeling of the musculature to connective tissue.
- a secondary PH occurs, inter alia, as a result of lung disease. This can occur as a characteristic feature acutely in the context of an "Adult Respiratory Distress Syndrome" (Kolle et al., N Engl J Med. 1995 Jan 5; 332 (l): 27-37), significantly worsening the prognosis of ARDS and special forms of therapy necessary to prevent right heart failure (Moloney et al., Eur. Respir J. 2003 Apr; 21 (4): 720-7). Similarly, chronic lung disease can be secondarily complicated by the onset of PH and thereby the prognosis Han et al., Circulation, 2007 Dec 18; 116 (25): 2992-3005).
- pulmonary hypertension includes certain forms of pulmonary hypertension as defined by the World Health Organization (WHO) ⁇ Clinical Classification of Pulmonary Hypertension, Venice, 2003; Simmenau et al, JAm Coli Cardiol (2004), 43, Suppl 1 (12) S5-S12).
- WHO World Health Organization
- the standard therapies used to treat acute PH are capable of improving the quality of life, exercise tolerance and prognosis of patients.
- the applicability of these drugs is limited by the z.T. restricted serious side effects and / or complex application forms.
- the period of time during which a patient's clinical situation can be improved or stabilized under specific monotherapy is limited.
- New combination therapies are one of the most promising future treatment options for the treatment of pulmonary arterial hypertension (Ghofrani et al., Herz 2005, 30, 296-302).
- the exploration of new pharmacological mechanisms for the treatment of PH is of particular interest.
- New therapies should be combinable with the known ones.
- Another side effect of a resistance-reducing therapy in secondary PH which can occur especially in a systemic therapy of a secondary PH with inhomogeneous lung injury (eg ARDS and COPD) is a decrease in arterial oxygen content despite successful treatment of pulmonary hypertension by opening pulmonary shunts (Stolz et al., Eur Respir J. 2008 Sep; 32 (3): 619-28.).
- the object of the present invention to find new methods for the treatment of primary and secondary PH, which do not have the disadvantages presented above.
- the normal ambient air is composed mainly of the elements nitrogen (about 78% by volume) and oxygen (about 21% by volume). If you replace the nitrogen content by the noble gas helium, you get Heliox - a mixture of helium and oxygen.
- Helium has some basic other properties compared to nitrogen and oxygen.
- the noble gas helium (He) is characterized by a lack of color, odor and tastelessness and low solubility in aqueous solutions and fatty substances (eg only 30% of the solubility of oxygen or nitrogen in an oil-water mixture (Brubakk AO, Neumann TS Bennett &Elliof's Physiology and Medicine of Diving, 5th edition, Saunders Verlag, Edinburgh 2003)). Hyperbaric helium exposure therefore does not result in narcotic effects such as those known from nitrogen or xenon. These favorable properties are also found in the mixture of helium with oxygen (Heliox) and thus allow diving below 60m. In commercial diving, the nitrogen contained in the breathing air is completely or partially replaced by helium. As a result, among other things, the formation of gas bubbles during emergence (decompression or caisson disease) can be reduced.
- the Heliox effect in the respiratory tract depends inter alia on the localization of an obstruction. Although the width of the airways becomes narrower towards the periphery, the increasing number of bronchi in the deeper generations results in a larger overall cross-section and thus lower overall resistance. The major part of the airway resistance is therefore in the upper respiratory tract to the 5th-6. Bronchial generation localized (West JB Respiratory Physiology-the essentials, 5 * edition, 1995, Williams and Wilkins, Baltimore). In many pathological conditions of the lung (e.g., ARDS, COPD), even small respiratory tract infections are present in some cases. significant bottlenecks that can lead to a change in the flow profile. The transition from a laminar to a turbulent flow can be estimated using the Reynolds number (RE).
- RE is calculated according to:
- a helium-oxygen mixture can be used in diseases of the lower respiratory tract (eg COPD or asthma) with helium-oxygen gas mixtures.
- diseases of the lower respiratory tract eg COPD or asthma
- helium-oxygen gas mixtures eg COPD or asthma
- the breath-facilitating effect is also the focus here due to the described effect of transferring a turbulent flow into a laminar gas flow in the foreground.
- the mechanism of action of a more effective deposition of aerosol particles (eg ⁇ 2 mimetics) into more peripheral parts of the lung is also discussed (Anderson et al., Am Rev Respir Dis. 1993; 147: 524-8).
- helium-oxygen mixtures on the vessel side can lower the resistance can be used for the treatment and / or prophylaxis of pulmonary hypertension, for example in acute (eg ARDS) pulmonary or cardiac (left-sided) atrial or left ventricular) diseases as well as valvular heart disease.
- helium-oxygen mixtures are therefore suitable not only for the treatment of airway obstruction, but also for the treatment and / or prophylaxis of pulmonary hypertension in chronic obstructive pulmonary disease, interstitial lung disease, sleep apnea syndrome, diseases with alveolar hypoventilation, altitude sickness and suitable for pulmonary developmental disorders.
- the helium-oxygen mixtures are suitable for the treatment and / or prophylaxis of pulmonary arterial hypertension due to chronic thrombotic and / or embolic diseases, such as thromboembolism of the proximal pulmonary arteries, obstruction of the distal pulmonary arteries and pulmonary embolism.
- the compounds according to the invention can be used for the treatment and / or prophylaxis of pulmonary arterial hypertension in conjunction with sarcoidosis, histiocytosis X or lymphangioleiomyomatosis as well as pulmonary arterial hypertension caused by external vascular compression (lymph node, tumor, fibrosing mediastinitis).
- Helium-oxygen mixtures can be used alone or in combination with other active ingredients. Helium-oxygen mixtures can be used in a ratio of 20 to 80% helium. Preferably, a ratio with the highest possible helium content (up to 79%) is used. Particular preference is given to using a ratio of 79% helium / 21% oxygen.
- Percentages in the present invention are always percentages by volume.
- compositions containing a helium-oxygen mixture and one or more other active ingredients for the treatment and / or prophylaxis of the aforementioned diseases are pharmaceutical compositions containing a helium-oxygen mixture and one or more other active ingredients for the treatment and / or prophylaxis of the aforementioned diseases.

- the following compounds are listed here:
- soluble guanylate cyclase such as in particular the compounds described in WO 01/19355, WO 01/19776, WO 01/19778, WO 01/19780, WO 02/070462 and WO 02/070510 in combination with helium -oxygen mixtures

- Antiviral substances such as aspirin in combination with helium-oxygen mixtures
- helium / oxygen mixture ratios preference is given to using helium / oxygen mixture ratios with as high a proportion of helium as possible (up to 79%). It is particularly preferred to use a ratio of 79% helium / 21% oxygen, although in the case of increased oxygen demand of a patient, this proportion may possibly have to be reduced in the helium fraction.
- Another object of the present invention is the use of helium-oxygen mixtures alone or in combination with one or more of the aforementioned combination active ingredients for the manufacture of a medicament for the treatment and / or prophylaxis of pulmonary hypertension in left atrial or left ventricular diseases, left-sided heart valve diseases, acute lung diseases (eg ARDS), chronic obstructive pulmonary disease, interstitial lung disease, sleep apnea syndrome, diseases with alveolar hypoventilation, altitude sickness, pulmonary developmental disorders, chronic thrombotic and / or embolic diseases such as proximal pulmonary thromboembolism, distal pulmonary artery obstruction and pulmonary embolism with sarcoidosis, histiocytosis X or lymphangioleiomyomatosis as well as a pulmonary artery caused by external vascular compression (lymph nodes, tumors, fibrosing mediastinitis) Hypertension.

- the medicaments to be prepared according to the invention or to be used according to the invention comprise at least one of the compounds according to the invention, usually together with one or more inert, non-toxic, pharmaceutically suitable excipients in combination with helium-oxygen mixtures.
- the use of Heliox on the one hand independently of the active ingredient can influence the pulmonary vascular resistance and also increase the effect of the inhaled liquid, solid or gaseous active substance.
- the reinforcement succeeds, for example, by a higher deposition rate, deposition distal to flow obstacles or in poorly ventilated areas.
- Heliox can be used, and it is also conceivable that an inhalant produced with or without heliox but spent with Heliox in the lungs.
- the preparation of the combination of heliox and a liquid, solid or gaseous active substance can be carried out by means of commercially available devices (for example 2.4 MHz, Optineb-IR, from Nebu-Tec).

- Inhalation medicines including powder inhalers, nebulizers
- nasal drops solutions or sprays.
- the helium-oxygen mixtures are commercially available in a mixing ratio of mostly 79% helium and 21% oxygen.
- Heliox does not specifically describe this mixing ratio, but only the mixture of helium with oxygen.
- Each of these helium / oxygen mixtures, wherein a minimum oxygen content of 21% is necessary for physiological reasons, can be converted into the mentioned application forms. This can be done in a manner known per se by mixing with inert, non-toxic, pharmaceutically suitable excipients.

- PH therapy eg prostacyclin analogs, sGC activators
- the invention is not limited to the examples, because it was furthermore shown that this resistance-reducing effect of helium-oxygen mixtures in the pulmonary vascular bed can be increased by the additional inhalation of active substances:
- an ALI / ARDS is used by removal of the pulmonary surfactant by lavage on anesthetized piglets with subsequent intratracheal application of a 20% meconium solution.
- the animals experience a pronounced gas exchange disorder with secondary pulmonary hypertension.
- the model described corresponds to the so-called meconium aspiration syndrome.
- Measurements of various physiological parameters are performed according to a standardized procedure (Geiger et al., Intensive Care Med ; 34: 368-76) in the so-called Göttinger Minipig® (Ellegaard, DK) under adequate analgesic sedation.
