Definitions
- the object of the present invention is the use of a cannabinoid CBj receptor antagonist compound, derived from pyrazole, for the preparation of medicaments useful in the prevention and treatment of chronic bronchitis and chronic obstructive pulmonary disease ( COPD, COPD: from English chronic obstructive pulmonary disease).
- COPD chronic obstructive pulmonary disease
- Endogenous cannabinoids such as anandamide, produce profound inhibition of coughing and contraction of the bronchial muscle. It has been observed that smoked cannabis shows broncho-dilating activity and it is known to use cannabinoid receptor agonists to treat various pathologies including bronchial asthma (Tashkin DP, Shapiro BJ, Lee YE, Harper EC:
- CB ⁇ cannabinoid receptors by SR 141716A has no bronchomotor consequences per se but significantly increases the bronchoconstriction and cough caused by the administration of capsaicin.
- Blockade of CB ⁇ cannabinoid receptors by SR 141716A inhibits the anti-inflammatory effect of two cannabinoid agonists HU210 and WLN 55212-2 produced on the migration of neutrophils in a peritonitis model in mice (Smith SR, Denhardt G, Terminelli C: The anti-inflammatory activities of cannabinoid receptor ligands in mouse peritonitis models, EUT. J. Pharmacol. 2001, 432: 107-119).
- the CB receptor antagonists derived from pyrazole are active at the bronchopulmonary level and can be used in the treatment of chronic bronchitis.
- the term “cannabinoid receptor antagonist derived from pyrazole” means N-piperidino-5- (4-chlorophenyl) -l- 2,4- dichlorophenyl) -4-methylpyrazole-3-carboxamide known by the name SR141716 and whose international common name is rimonabant described in European patent 656354, and N-piperidino-5- (4-bromophény ⁇ ) -l-C2,4- dichlorophenyl) -4-ethylpyrazole-3-carboxamide described in European patent 1150961. Clinical studies carried out with rimonabant have shown that it reduces the hunger, the caloric intake and the body weight of obese patients (G. Le Fur, 2003, 35, First European Workshop on Cannabinoi
- a compound which is a CBj cannabinoid receptor antagonist, derived from pyrazole can be used for the preparation of medicaments useful for preventing and treating chronic bronchialitis and chronic obstructive pulmonary disease as well as the associated chronic brown hite. to chronic pulmonary bronchopneumopathy.
- the pharmaceutical compositions according to the present invention contain an effective dose of a cannabinoid CB receptor antagonist compound, derived from pyrazole, as well as at least one pharmaceutically acceptable excipient. Said excipients are chosen according to the pharmaceutical form and the nxode of administration desired, from the usual excipients which are known to those skilled in the art.
- the active principle can be administered in unit administration form , in admixture with conventional pharmaceutical excipients, to animals and humans for the prevention or treatment of the above disorders or diseases.
- Suitable unit dosage forms include oral forms such as tablets, soft or hard capsules, powders, granules and oral solutions or suspensions, sublingual, buccal, intratracheal, intraocular, intranasal, inhalation administration forms, topical, transdermal, subcutaneous, intramuscular or intravenous administration forms, rectal administration forms and implants.
- EXAMPLE 1 animal model Migration of cells into the bronchoalveolar space after activation by bacterial E PS (lipopolysaccharide). 28 to 30 g mice are stimulated by an intratracheal exposure of 10> ⁇ g of LPS. 24 hours after the LPS injection, the animals are anesthetized with pentobarbital and a bronchoalveolar lavage is carried out. The washing fluids are recovered, centrifuged and then the cells are resuspended.
- E PS lipopolysaccharide
- the number of cells is counted by differentiating, according to standard morphological criteria, the eosinophilic, neutrophilic and mononuclear cells.
- Intratracheal injection of LPS induces a significant increase in the number of mononuclear and neutrophil cells in the bronchoalveolar space of mice.
- Rimonabant is administered to animals 1 hour before LPS in doses varying from 0.3 to 30 mg / kg / ip
- the effective dose 50 (ED 50 ) which inhibits the migration of neutrophil cells by more than 80% is 2.3 (+ 0.3) mg / kg.
- ED 50 1.9 (+ 0.5) mg / kg.
- This model induced by bacterial LPS is conventionally used, in particular in the bronchopulmonary level, where it produces an infiltration of polymorphonuclear neutrophil cells into the bronchopulmonary tissues followed by a release, of mediators which cause tissue damage.
- This neutrophil infiltration is the consequence of the activation of mononuclear cells (macrophages which constitute the first defense barrier at the level of the bronchial epithelium and T lymphocytes) directly stimulated by LPS and which release mediators (chemokines) inducing extravasation. neutrophils and their attraction to activated mononuclear cells.
