Composition comprising a pulmonary surfactant and a PDE5 inhibitor for the treatment of lung diseases
View Patent ↗The invention relates to the combined administration of a pulmonary surfactant and a PDE5 inhibitor for the treatment of a disease in which pulmonary surfactant malfunction and/or phosphodiesterase 5 (PDE5) activity is detrimental.
1. A method for treating or reducing the onset of symptoms of a disease in which pulmonary surfactant malfunction and/or phosphodiesterase 5 (PDE5) activity is detrimental, or treating or reducing the severity of a disease in which pulmonary surfactant malfunction and/or phosphodiesterase 5 (PDE5) activity is detrimental in a patient, comprising administering intratracheally or intrabronchially to a patient in need thereof an effective amount of (1) Lusupultide and (2) Sildenafil or a pharmaceutically acceptable salt thereof wherein the disease in which pulmonary surfactant malfunction and/or phosphodiesterase 5 (PDE5) activity is detrimental is selected from the group consisting of COPD, bronchitis, bronchial asthma, pulmonary fibroses, emphysema, interstitial pulmonary disorders, pneumonia, ALI, ARDS and asthma bronchiale.
2. The method according to claim 1 , wherein the (1) Lusupultide and (2) Sildeneafil or a pharmaceutically acceptable salt thereof are administered simultaneously.
