Definitions
- Glaucoma is an eye condition characterized, among other symptoms, by a slow or rapid increase in pressure
- Glaucoma leads to the destruction of the optic nerve fibers and can lead to loss of vision.
- glaucoma One of the major treatments for glaucoma is to reduce intraocular pressure.
- the drugs currently known for the treatment of glaucoma present difficulties of use.
- pilocarpine has local side effects, while active principles such as epinephrine or an adrenergic beta-blocker: timolol, are difficult to use for certain patients suffering from cardiovascular disease or who cannot withstand the effects.
- the present invention relates to the use of a potassium agonist for the preparation of a medicament intended to reduce and / or control the abnormally high intraocular pressure.
- the invention also relates to the use of a potassium agonist in combination with another active ingredient for the treatment of glaucoma.
- the active ingredient used in combination with the potassium agonist compound may be either a beta-adrenergic blocking agent, itself useful for lowering intraocular pressure, or an anti-inflammatory drug, in particular a steroidal anti-inflammatory drug or corticosteroid for the treatment of glaucoma, a side effect of which is an intraocular increase.
- the potassium agonist can be used in combination with a beta-adrenergic blocking agent and a steroidal anti-inflammatory.
- the invention also relates to a set or kit comprising on the one hand a potassium agonist in a topical ophthalmic excipient and on the other hand an anti-inflammatory in an ophthalmic excipient, preferably topical for the treatment of glaucoma.
- the present invention also relates to pharmaceutical compositions containing a potassium agonist and a steroid or a potassium agonist and a beta-adrenergic compound.
- a potassium agonist is called a potassium channel agonist.

- Potassium agonists are compounds that facilitate the opening of cellular potassium channels. This is reflected, in particular, by a relaxing effect on the smooth muscles.
- the potassium agonist effect of a compound can, for example, be measured by its inhibitory power of spontaneous contractile activities of the isolated portal vein of the rat.
- the potassium agonists whose use is the subject of the present invention are derivatives of chroman, quinoline or

- concentrations of each of the active principles of the composition which make it possible to reduce the intraocular pressure are variable, they have a lower limit below which the composition is inactive. This lower limit is approximately 5% of the effective dose and depends on the potency of the potassium agonist and, possibly, that of the beta-blocker used, the age and size of the patient, as well as the severity of disease.
- Steroidal anti-inflammatory drugs include hydrocortisone, cortisone, flunisolide, beclomethasone, alclomethasone, flunisolide, chlorocortolone, diflorasone, alkinolide, fluocinonide, fluocinolone, deoximethasone, medrysone, parametone dichloro-9,21 / (furanylcarbonyl-2) oxy-17 / hydroxy-11 methyl-16 ⁇ pregnadiene-1,4 dione-3,20 and the

- the rise in intraocular pressure can occur following any mode of administration of these drugs: systemic administration, generally oral, local injection, for example the injection of a delayed form and particularly during an ophthalmic injection. topical or intravitrous.
- a potassium agonist may be administered after steroid therapy to lower the elevated intraocular pressure or it may be co-administered with the steroid to suppress the effect of increasing the intraocular pressure of the steroid, without interfering with its anti-inflammatory activity.
- any combination of dosage forms can be used to administer the combination of the anti-inflammatory steroid and the potassium agonist: both drugs in oral form, or both in topical form, or one in form oral, the other in topical form, or the steroid in the form of a local injection and 1 potassium agonist in topical form; a preferred combination is topical administration of the steroid and potassium agonist. Particularly preferred is a topical ophthalmic composition comprising both the steroid and the potassium agonist.

- a unit dosage form comprises from 20 ug to 600 ⁇ g to be applied to the eye. In each individual case, the amount to be administered and the frequency of administration depend on the potency of the steroid chosen, the severity of the disease and the response of the patient. For each particular steroid, one can determine which potassium agonist to use and at what concentration.
