Abstract

Preparation for the treatment of the attenuation of cystic fibrosis symptoms. Said treatment comprises the application of a pharmaceutical composition in the form of a spray containing as active principle active lipids (L.A.), which are a mixture of phosphatidylcholine, phosphatidylethanolamine and ovi vitellus glycerides, intended to fluidize the cell membranes. The figure herewith appended shows the expectoration volume and the duration of cough before and after the administration of a composition of active lipids (L.A.) according to the invention.

Description

COMPOSITIONS CONTENANT DES LIPIDES ACTIFS Domaine de 1'invention COMPOSITIONS CONTAINING ACTIVE LIPIDS Field of the Invention
L'invention concerne une préparation pour le trai¬ tement et l'atténuation des symptômes de la fibrose kystique. Ce traitement consiste à appliquer un aérosol de certains lipides actifs.The invention relates to a preparation for the treatment and attenuation of the symptoms of cystic fibrosis. This treatment consists in applying an aerosol of certain active lipids.
Arrière-plan de l'inventionInvention background
La fibrose kystique (PK ou mucoviscidose) est une maladie génétique des enfants et se caractérise par le fait que les voies pulmonaires sont obstruées par un mu¬ cus visqueux (R.E. ood, et al, Cystic Fibrosis, Am.Rev. Resp.Dis .L1J5 833-877 (1976)) .Cystic fibrosis (PK or cystic fibrosis) is a genetic disease of children and is characterized by the fact that the pulmonary passages are obstructed by a viscous mucus (RE ood, et al, Cystic Fibrosis, Am.Rev. Resp.Dis. L1J5 833-877 (1976)).
L'étiologie de la maladie n'est pas connue et il n'existe aucune thérapie efficace ; l'issue est gênéra- lement fatale. La thérapie actuelle est basée sur le soulagement des difficultés respiratoires par kinésithé¬ rapie (R.B. Mellins, Pulmonary physiotherapy in the pé¬ diatrie âge group, Am.Rev.Resp.Dis 110 Supp.pl37 (1974)) . Certains types de thérapie par aérosol sont utilisés (P.O. Alderson et al, Pulmonary déposition of aérosols in children with cystic fibrosis, J.Pediatr. 8_ 479 (1974)).The etiology of the disease is unknown and there is no effective therapy; the outcome is usually fatal. Current therapy is based on the relief of breathing difficulties by physiotherapy (R.B. Mellins, Pulmonary physiotherapy in the pediatrics age group, Am.Rev.Resp.Dis 110 Supp.pl37 (1974)). Certain types of aerosol therapy are used (P.O. Alderson et al, Pulmonary deposition of aerosols in children with cystic fibrosis, J. Pediatr. 8_ 479 (1974)).
Résumé de l'inventionSummary of the invention
Il est fourni une composition pharmaceutique sous forme d'aérosol contenant comme principe actif des lipi¬ des actifs, qui sont un mélange de phosphatidylcholine, de phosphatidylethanolamine et de glycerides du jaune d'oeuf, conçu pour fluidiser les membranes cellulaires (D. Héron et al. Alleviation of drug withdrawal symptoms by treatment with a potent mixture of natural lipids, Eur. J. Pharmacol, 83_ 253-261 (1982)) . Ce produit est mis dans le commerce par Natural Pharmaceutical Corporation, Los Angeles, E.U.A.A pharmaceutical composition is provided in the form of an aerosol containing as active principle lipi¬ active agents, which are a mixture of phosphatidylcholine, phosphatidylethanolamine and glycerides of egg yolk, designed to fluidize cell membranes (D. Heron and al. Alleviation of drug withdrawal symptoms by treatment with a potent mixture of natural lipids, Eur. J. Pharmacol, 83_ 253-261 (1982)). This product is marketed by Natural Pharmaceutical Corporation, Los Angeles, E.U.A.
FEU2 LΞ DE REM ACEMENT Le principe actif, désigné ici par les initiales LA, était dispersé dans de l'eau distillée, par tourbillone- ent. D'autres formules d'aérosol peuvent être utilisées. En général, une concentration de 1 à 5 pour cent en poids est satisfaisante. Les traitements dont il est rendu comp¬ te ici ont été effectués avec 2 % en poids de L.A., par "aérosolisation" . La quantité administrée était de 3 à 5 ml de cette dispersion pendant 15 à 20 minutes, deux fois par jour. On a évalué l'efficacité des nouvelles compositions en mesurant le temps moyen nécessaire pour expectorer un certain volume de mucus, 10 ml par exemple, et à partir de la quantité totale de mucus expectoré au cours d'une quinte de toux. Les patients étaient des enfants de 8 à 12 ans. Certains de ces patients souffraient d'une infec¬ tion pulmonaire chronique par Pseudo onas aeruginosa. Chez tous les enfants soumis au traitement, on a observé une réduction progressive de la durée de la toux. Au bout de 7 jours de traitement, la durée de la toux était réduite d'un facteur de 6 à 10, et la quantité de mucus expectoré était augmentée d'un facteur de 4 à 6. L'état physique et clinique était nettement amélioré. On n'a observé d'effet néfaste chez aucun des patients. Un résumé est donné di-dessous.FIRE2 LΞ OF REPLACEMENT The active principle, designated here by the initials LA, was dispersed in distilled water, by vortex. Other aerosol formulas can be used. In general, a concentration of 1 to 5 percent by weight is satisfactory. The treatments of which it is reported here have been carried out with 2% by weight of LA, by "aerosolization". The amount administered was 3 to 5 ml of this dispersion for 15 to 20 minutes, twice a day. The efficacy of the new compositions was evaluated by measuring the average time necessary to expectorate a certain volume of mucus, 10 ml for example, and from the total amount of expectorated mucus during a coughing fit. The patients were children 8 to 12 years old. Some of these patients suffered from chronic lung infection with Pseudo onas aeruginosa. In all children treated, there was a gradual reduction in the duration of cough. After 7 days of treatment, the duration of the cough was reduced by a factor of 6 to 10, and the quantity of expectorated mucus was increased by a factor of 4 to 6. The physical and clinical condition was markedly improved. . No adverse effects were observed in any of the patients. A summary is given below.
