This invention relates to topical ophthalmic compositions comprising an ascomycin, e.g. for treatment of inflammatory diseases such as blepharitis.
Under “ascomycin” is to be understood ascomyecin itself or a derivative, antagonist, agonist or analogue thereof, e.g. a compound of the FK 506 class.
Preferred ascomycins for use in the present invention include FK506 or a derivative, antagonist, agonist or analogue of FK506, which retain the basic structure and modulate at least one of the biological properties (for example immunological properties) of FK506 such as described in e.g.
EP 184162, EP 315978, EP 323042, EP 423714, EP 427680, EP 465426, EP 474126, WO 91/13889, WO 91/19495, EP 484936, EP 532088, EP 532089, EP 569337, EP 626385, WO 93/5059 and the like; 33-epi-chloro-33-desoxy-ascomycin as disclosed in Example 66a in EP 427680 (hereinafter referred to as Compound A); {[1E- (1R,3R,4R)]1R,4S,5R,6S,9R,10E,13S,15S,16R,17S,19S,20S}-9-ethyl-6,16, 20-trihydroxy-4-[2-(4- hydroxy-3-methoxy-cyclohexyl)-1-methylvinyl]-15,17-dimethoxy-5,11,13,19-tetramethyl-3-oxa-22- aza-tricyclo[18.6.1.0(1,22)]heptacos-10-ene-2,8,21,27-tetraone as disclosed in Examples 6d and 71 in EP 569 337 (hereinafter referred to as Compound B); and {1R,5Z,9S5,12S-[1E- (1R,3R,4R)],13R,145,17R,18E, 21S,23S,24R,25S,27R}17-ethyl-1,14-dihydroxy-12-[2-(4-hydroxy- 3-methoxy-cyclohexyl)-1-methylvinyl]-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4- aza-tricyclo{22.3.1.0(4,9)] octacosa-5,18-diene-2,3,10,16-tetraone, also known as 5,6-dehydro- ascomycin as disclosed in Example 8 in EP 626 385 (hereinafter referred to as Compound C); imidazolylmethyloxyascomycin, as disclosed in Example 1 and as compound of formula | in WO 97/08182 (hereinafter referred to as Compound D); 32-O-(1-hydroxyethylindol-5-yl)ascomycin, also known as Indolyl-ASC or L-732 531 as disclosed in Transplantation 65 (1998) 10-18, 18- . 26, on page 11, Figure 1 (hereinafter referred to as Compound E); or (32-deoxy-32-epi-N1- tetrazolyl)ascomycin, also known as ABT-281 as disclosed in J. Inv. Derm. 112 (1999), 729-738, . on page 730, Figure 1 (hereinafter referred to as Compound F).
FK 506, Compounds A, B, C, D, E, and F are preferred ascomycins, more preferred are } Compounds A, B, and C, especially Compound A. Particularly preferred is Compound A.
Ascomycins have a variety of useful pharmacological actions, e.g. treatment of blepharitis, and may be administered topically. However, inter alia because of their physicochemical properties, e.g. high molecular weight and lipophilicity the ascomycins have posed problems for topical administration. Furthermore due to the sensitivity of the delicate eye tissues, only ophthalmically acceptable components may be employed in ophthalmic compositions.
Formulations, e.g. in form of an ointment, for application to the skin comprising ascomycins have been described e.g. in EP 474126 or EP 1135163. However, due to the irritation potential of some of the components used, these ointments may not be topically applied to the eye.
Applicants have now found that ophthalmic compositions comprising an ascomycin and a carrier comprising a medium chain fatty acid triglyceride and/or isopropyl myristate are highly efficient and well tolerated by the ocular tissue.
Preterred compositions of said king comprise 33-epi-chloro-33-desoxy-ascomycin.
The active agent may be in suspension, e.g. partially in suspension in the vehicle. Preferably the active agent is however dissolved, e.g. partially dissolved, in the vehicle.
If the active agent is suspended, it may preferably be used in a micronized form. The suspension may contain particles of ascomycin of from 5, e.g. from 10, to about 90, preferably to about 25 microns in diameter. The particles of the ascomycin may be produced in conventional manner, e.g. by grinding or milling. In case the active agent exists in different polymorphic or pseudo-polymorphic forms, the thermodynamic stable form is preferably used in . a suspension type formulation. . The active agent is e.g. present in the compositions of this invention in an amount of from 0.01 to 5% by weight, e.g. 0.05 to 3% by weight, e.g. from 0.1 to 2% by weight, e.g. from about 0.2 to about 1% by weight based on the total weight of the composition.
The carrier comprises isopropyl myristate or a medium chain triglyceride or a mixture thereof.
For the purposes of this application isopropyl myristate means a compound comprising not less than 90 percent of isopropyl tetradecanoate together with variable amounts of other fatty acid isopropyl esters.
Isopropyl myristate is preferably used in amounts from 1 to 20%, more preferably from 1 to 15, e.g. from about 2 to about 8% by weight based on the total weight of the composition.
Medium chain fatty acid triglycerides are preferably Cg to C,, fatty acid triglycerides, e.g. as known and commercially available under the trade name Acomed®, Myritol®, Captex®,
Neobee®M5F, Miglyol®810, Miglyof®812, Mazol®, Sefsoi®860, Sefsol®870. Especially preferred is the product Miglyol®812. Such medium chain fatty acid triglycerides are usually obtained from the oil extracted from the hard, dried fraction the endosperm of Cocos nucifera L. or from the dried endosperm of Elaeis guineensis Jaqu. They consist of a mixture of triglycerides of saturated fatty acids, mainly of caprylic acid and of capric acid, and contain not less than 95 percent of saturated fatty acids with 8 and 10 carbon atoms.
The medium chain fatty acid triglycerides may be present in an amount of 1 to 80% by weight based on the total weight of the composition, preferably about 10 to about 55% by weight.
Preferred compositions according to the invention include compositions which are in the form of an ointment and compositions which are in the form of an emulsion, in particular an oil-in-water emulsion.
The compositions according to the invention may therefore comprise a carrier which further comprises an ointment base. Suitable ointment bases include, for instance, ophthalmically . acceptable oil and fat bases, such as (a) natural wax e.g. white bees wax, carnauba wax, wool wax (wool fat), purified lanolin, . anhydrous lanolin, (b) petroleum wax e.g. solid paraffin, microcrystalline wax,
(c) hydrocarbons e.g. liquid paraffin, white petrolatum (e. g. white Protopet®), yellow petrolatum, or (d) combinations thereof.
The above mentioned oil and fat bases are described, for instance, in the British
Pharmacopoeia, Edition 2001, or in the European Pharmacopoeia, 3" Edition.
The ointment base may be present in an amount from 1 to about 95% by weight based on the total weight of the composition, e. g. 40 to 95% by weight. A preferred range for the percentage of ointment base is 45 to 90% by weight based on the total composition.
The ointment compositions according to the present invention may further comprise some water, preferably in an amount of less than 10% by weight based on the total amount of composition.
The ointment type compositions of the present invention may further comprise ophthalmically acceptable surfactants/emulsifiers.
The ophthalmic compositions of the instant invention include also compositions wherein the carrier further comprises water and an emulsifier instead of the ointment base.
Water may preferably be present in these compositions in amounts of 60 to 90% by weight, e.g. 70 to 85% by weight.
The emulsifier is preferably an ethoxylated C,s-Csalkyl carboxylic acid (CAS Registry No. 68989-61-7). Corresponding emulsifiers are available under names like Pegoxol 7 stearate,
Dion 37, Tefose 63, Tefose 70 or Stearox SP9 etc and exhibit in particular a good ocular . tolerance. The emulsifier is used in amounts as required, e.g. 0.5 to 10% by weight, preferably 1 to 5% by weight.
The emulsifier may be accompanied by suitable co-emulsifiers, for example Lauroyl
Macrogolglycerides, which are mixtures of mono-, di- and triesters of glycerol and lauric acid and mono- and diesters of macrogols (polyethylene glycols) having a mean molecular weight of } e. g. between 300 and 1500.

Preferred compositions of the present invention consist essentially of an ascomycin, a medium chain triglyceride, an ointment base and a preservative.
The compositions of the present invention are stable, as indicated by conventional tests, e.g. under stressed conditions, such as a temperature cycling test at 5 to 30°C or 40°C if relevant, or several months, e.g. 1 to 12 months, at 30°C. A suitable temperature cycle test may be carried . out for instance in the following way: the samples are kept 12 hours at 5°C and then 12 hours preferably at 30°C or 40°C if relevant (depending on the melting point of the tested ointments) for several month. The device type is for instance a Temperature Test Cabinet CTS T-40/25.
The ophthalmic compositions of the present invention may be prepared in conventional manner e.g. by mixing the preferably gamma-irradiated ascomycin powder with the appropriate excipients, e.g. by mixing the gamma-irradiated ascomycin powder with sterile filtered medium chain triglyceride, part of the ointment bases, e.g. the wool fat and/or liquid paraffin, and additional oil phase, if present, and ball mill the ascomycin in the liquid medium and subsequently aseptically add the ascomycin containing liquid medium to the matrix containing sterile preservative and remaining part of the ointment bases, e.g. white petrolatum.
It is also well possible, for example, to dissolve the ascomycin in preheated medium chain triglyceride, and to add the molten ointment base with the preservative. Thereafter a final sterile filtration through a 0.22 micron filter is performed,
Alternatively, the ascomycin may be dissolved e.g. in heated white petrolatum. The mixture may be filtered through a 0.2 micron filter, e.g. Durapore® membrane filter, and be allowed to cool and subsequently form a suspension. The suspension may be further ball milled to uniformly disperse the ascomycin.
The emulsion-type compositions may also be prepared in conventional manner, e.g. by dissolving the preferably gamma-irradiated ascomycin powder with the sterile filtered oily phase, in particular the medium chain triglyceride, adding the emulsifier and/or co-emulsifier and dispersing said mixture in an appropriate quantity of sterile water using conventional emulsification devices, e.g. a high-speed stirrer or an ultrasonic generator etc.
