Definitions
- the present invention relates to compositions for nasal application of cGMP-PDE inhibitors, in particular of PDE5 inhibitors, which contain a small amount of a local anesthetic in addition to the cGMP PDE inhibitor.
- Cyclic guanosine-3 ', 5'-monophosphate phosphodiesterase inhibitors abbreviated cGMP PDE inhibitors
- cGMP PDE inhibitors have a known spectrum of action (cf., for example, EP-A-0 463 756, WO 99/24433).
- cGMP -PDE inhibitors in particular PDE5 inhibitors, are suitable for the treatment of male erectile dysfunction (cf. Rajfer et al., New England J. Med. 326 (1992), 90; Murray, Drug News & Perspectives 6 (1993), 150).
- WO 94/28902 then described the use of certain cGMP-PDE inhibitors for the treatment of male erectile dysfunction, one of which (sildenafil citrate, Viagra ® ) is now approved as an orally administrable medication for this indication.
- a disadvantage of oral administration is the delayed onset of action, which in particular in this indication is at the expense of the spontaneity desired by the patient.
- first-pass effects or food effects can impair the effectiveness of the orally administered drug.
- benzyl alcohol is also known as a preservative or as a solubility enhancer and is described in these functions in EP-A-0 967 214 and WO 00/00199 as one of several auxiliaries which can also be used for the formulations mentioned therein ,
- benzyl alcohol is unable to reduce or avoid the disadvantages described above which occur in the nasal application of cGMP PDE inhibitors.
- WO 99/15177 describes liquid-crystalline nicotine preparations to which a local anesthetic is added in order to avoid adverse effects of the nicotine, which are caused by its local irritant effect.
- the local anesthetic works by blocking peripheral pain receptors. It should be noted that cGMP PDE inhibitors do not, or only to a small extent, produce such a local irritant effect when administered nasally.
- GB-A-2 315 673 proposed the intranasal application of local anesthetics such as lidocaine in addition to a 5-HTID agonist for the treatment of migraines.
- local anesthetics such as lidocaine
- this proposal is based on the vasodilating effect of local anesthetics, which leads to an accelerated absorption of the 5-HT1D agonist and thus to a faster onset of action.
- composition which comprises at least one cGMP PDE inhibitor and at least one local anesthetic, the local anesthetic not being benzyl alcohol.
- cGMP-PDEs Cyclic guanosine 3 ', 5'- monophosphate metabolizing phosphodiesterases
- cGMP PDE inhibitors are therefore, according to the present invention, compounds which contain one or more of these cGMP- According to the invention, preference is given to compositions which, in addition to one or several local anesthetics comprise one or more inhibitors of phosphodiesterase 5.
- a PDE 5 inhibitor should be understood to mean a compound which primarily inhibits PDE 5.
- Preferred according to the invention are compositions which, in addition to one or more local anesthetics, comprise one or more phosphodiesterase 5 inhibitors which inhibit the PDE5 with an IC 50 value of less than 100 nM, preferably less than 30 nM and a selectivity compared to the PDE5 PDE 1 by a factor of 50, preferably 100, and compared to PDE 4 by a factor of 300, preferably 1000.
- the IC 50 values can be determined, for example, in accordance with the procedure described in WO 99/24433. The relevant content of WO 99/24433 is expressly referred to here. The determination of the above IC 50 values is, however, fundamentally familiar to the person skilled in the art and can also be carried out in other ways.
