PATENT DESCRIPTION The invention relates to the use of bradykinin antagonists for the preparation of medicaments for the treatment of virus diseases.

Bradykinin and related peptides are potent inflammation- and pain-generating and vasoactive endogenous substances. The use of bradykinin antagonists as agents for combating states mediated, induced or assisted by bradykinin is known (EP 0370453).

Surprisingly, it has now been found that bradykinin antagonists are suitable agents for the treatment of virus diseases.

The present invention furthermore relates to combination preparations which comprise, in addition to a bradykinin antagonist, at least one other antiviral agent. The particular advantage of these combination preparations lies in the fact that the action of the viruses (for example skin lesions) and also the spread of the viruses are combated with particular persistence.

Various other antiviral agents can be employed according to the invention, such as, for example, acyclovir, Val-acyclovir, pencyclovir, BVA-uracil, vidarabine, iododeoxyuridine, broravir, zidovudine (AZT), didanosine (DDI), dideoxycytidine (DDC) and lamivudine (3-TC), in particular acyclovir. The compounds mentioned are commercially obtainable or can be prepared by generally known processes (cf. Merck Index, 11th Edition Rahway, N.J. 1989, Drugs 45 (4), 488 et seq., 45 (5), 637 et seq., 1993).

The abovementioned preferred bradykinin antagonists are likewise preferred for the combination preparations mentioned. A particularly preferred combination preparation comprises HOE 140 and acyclovir or equivalents or prodrugs thereof.

The abovementioned compounds and combination preparations can be employed according to the invention against various viral diseases. They are of particular importance for combating herpes viruses (for example HSV-1, HSV-2, HSV-3, VSV) and for the recurrence of varicella zoster viruses (VSV).

The bradykinin antagonists are used in a suitable administration form as medicaments for the treatment of virus diseases.

Suitable pharmaceutical preparations comprise an active amount of the bradykinin antagonist--individually or in combination--together with an inorganic or organic pharmaceutically usable excipient and if appropriate together with one or more other antiviral agents.

The preparation can be used enterally, parenterally--such as, for example, subcutaneously, intramuscularly or intravenously--sublingually, epicutaneously, nasally, rectally, intravaginally, intrabuccally or by inhalation. The dosage of the active compound depends on the warm-blooded species, the body weight, age and the method of administration.

The pharmaceutical preparations of the present invention are prepared in solution, mixing, granulating or tablet-coating processes which are known per se.

For the oral use form or for application to the mucosae, the active compounds are mixed with the additives customary for this purpose, such as excipients, stabilizers or inert diluents, and are brought by customary methods into suitable dosage forms, such as tablets, coated tablets, hard gelatin capsules, aqueous, alcoholic or oily suspensions or aqueous, alcoholic or oily solutions. Inert excipients which can be used, are, for example, gum arabic, magnesia, magnesium carbonate, potassium phosphate, lactose, glucose, magnesium stearyl fumarate or starch, in particular corn starch. Formulation can thus be effected in either dry or moist granule form. Possible oily excipients or solvents are, for example, vegetable or animal oils, such as sunflower oil and cod-liver oil.

A preparation for topical use can be in the form of an aqueous or oily solution, lotion, emulsion or jelly, ointment or greasy ointment or, if possible, in spray form, it being possible to improve the adhesion, if appropriate, by addition of a polymer.

For the intranasal use form, the compounds are mixed with the additives customary for this purpose, such as stabilizers or inert diluents, and brought by customary methods into suitable dosage forms, such as aqueous, alcoholic or oily suspensions or aqueous, alcoholic or oily suspensions or aqueous, alcoholic or oily solutions. Chelating agents, ethylenediamine-N,N,N',N'-tetraacetic acid, citric acid, tartaric acid or salts thereof can be added to aqueous intranasal formulations. The nasal solutions can be administer ed by means of metered atomizers, or as nasal drops with a viscosity-increasing content or nasal gels or nasal creams.

Nebulizers or compressed gas packs using inert carrier gases can be utilized for inhalative use.

For intravenous, subcutaneous, epicutaneous or intradermal administration, the active compounds or physiologically tolerated salts thereof are dissolved, suspended or emulsified, if desired with the pharmaceutically customary auxiliaries, for example for isotonicizing or pH adjustment, as well as solubilizing agents, emulsifiers or other auxiliaries.

Because of the short half-lives of some of the medicaments described in body fluids, it is appropriate to use injectable sustained release formulations. Medicament forms which can be used are, for example, oily crystal suspensions, microcapsules, rods or implants, it being possible for the latter to be built up from tissue-tolerated polymers, in particular biodegradable polymers, such as, for example, those based on polylactic acid/polyglycolic acid copolymers or human albumin.

Topical administration is of particular importance for the compounds which can be used according to the invention and for the combination preparations which can be employed according to the invention.

The active dose is at least 0.001 mg/kg/day, preferably at least 0.01 mg/kg/day, in particular at least 0.1 mg/kg/day to not more than 3 mg/kg/day, preferably to not more than 1 mg/day/kg of body weight, based on an adult weighing 75 kg. The other antiviral agent is preferably employed, if appropriate, in its known dosage range.

The ratio of the amounts of bradykinin antagonist to other antiviral agent can extend over a wide range. A ratio of 1:100 to 100:1 is preferred.
