STORAGE-STABLE PROSTAGLANDIN COMPOSITIONS
BACKGROUND OF THF INVENTION _ The present invention relates generally to prostaglandin compositions. In particular, the present invention relates to storage stable, pharmaceutical compositions containing prostaglandins and surfactants. As used herein, the term "prostaglandin" or "PG" shall refer to prostaglandins and derivatives and analogues thereof including pharmaceutically acceptable salts and esters, except as otherwise indicated by context.
Prostaglandins have notoriously low water solubility, and are generally unstable.
Attempts have been made to solubilize and stabilize various prostaglandins by complexing them with different cyclodextrins. See, for example: EP 330 511 A2 (Ueno et al.) and EP 435 682 A2 (Wheeler). These attempts have met with varying success Surfactants and/or solubilizers have been used with other types of drugs having low water solubility. However, the addition of surfactants and/or solubilizers may enhance or adversely affect the chemical stability of drug compounds. See Surfactant a Systems, Their Chemistry, Pharmacy, and Biology, (eds. Attwood et al.), Chapman and Hall, New York, 1983, Ch. 11, particularly pp. 698 - 714.
The use of non-ionic surfactants, such as polyethoxylated castor oils, as solubilizing agents is known. See, for example, US 4,960,799 (Nagy).
The use of non-ionic surfactants such as polyethoxylated castor oils in stable emulsions is also known. US 4,075,333 (Josse) discloses stable, intravenous emulsion formulations of vitamins. El-Sayed et al., Int. J. Pharm., 13:303-12 (1983) discloses stable oil-in-water emulsions of an antineoplastic drug. US 5,185,372 (Ushio et al.) discloses topically administrable ophthalmic formulations of vitamin A which are stable preparations in which a non-ionic surfactant is used to form an emulsion of vitamin A
in an aqueous medium.

SUMMARY OF THE INVENTION
The present invention is directed to the use of polyethoxylated castor oils in pharmaceutical compositions containing prostaglandins. It has now been unexpectedly discovered that the use of such polyethoxylated castor oils in such compositions enhances the chemical stability of prostaglandins in pharmaceutical compositions. The compositions of the present invention can be administered to the body in a variety of ways. When topically applied to the eye, the compositions of the present invention provide both initial and continual comfort.
In a specific composition aspect, the invention provides a pharmaceutical composition comprising a prostaglandin, a polyethoxylated castor oil in an amount effective to enhance the chemical stability of the prostaglandin, and a pharmaceutically acceptable vehicle.
In a specific method aspect, the invention provides a method of enhancing the chemical stability of a pharmaceutical prostaglandin composition comprising adding a polyethoxylated castor oil to the composition.
The invention also provides for the use of the compositions in preventing or treating a disorder or disease requiring a prostaglandin for the prevention or treatment thereof; and a commercial package comprising the compositions and instructions associated therewith, the instructions describing indications of the pharmaceutical I
composition for use in preventing or treating a disorder or disease requiring a prostaglandin for the prevention or treatment thereof.

DETAILED DESCRIPTION OF THE INVENTION
Prostaglandin esters are difficult to formulate in storage-stable solutions as they tend to be hydrolytically unstable. In some instances, the parent acids of some prostaglandin esters are also unstable. The pharmaceutical compositions of the present invention, however, are storage stable. These compositions contain a prostaglandin and a stability-enhancing amount of a polyethoxylated castor oil.

Such polyethoxylated castor oils include those manufactured by Rhone-Poulenc (Cranbury, New Jersey) under the Alkamuls° brand, and those manufactured by BASF
(Parsippany, New Jersey) under the Cremophor° brand. It is preferred to use the polyethoxylated castor oils classified as PEG15 to PEG-50 castor oils, and more preferred to use PEG30 to PEG-35 castor oils.

The prostaglandin compositions of the present invention contain one or more polyethoxylated castor oils in an amount effective to enhance the stability of the prostaglandin. As Figure 1 illustrates the stabilizing effect of the polyethoxylated castor oil increases with increasing polyethoxylated castor oil concentration.
However, other ,o factors may limit the amount of polyethoxylated castor oil to be utilized in the compositions of the present invention. For example, too much polyethoxylated castor oil should not be used in order to avoid adversely affecting the prostaglandin's pharmacologic activity.

~ 2181172 In a separate clean glass vessel, the appropriate quantity of prostaglandin was added, followed by the appropriate quantity of the vehicle whose preparation was described above. The vessel was then tightly capped and sonicated in an ultrasonic bath for one hour or alternatively stirred with a magnetic stir bar overnight, until the prostaglandin was completely dissolved. The resulting solution was then sterile filtered (0.2 micron filter) into sterile containers. These containers were then aseptically plugged, capped and labelled.
The stabilizing effect of polyethoxylated castor oils in the compositions of the present invention was evaluated according to the following procedure.
1. Pipet the required quantity of 1% w/v prostaglandin ethanolic stock solution into 1.5 mL high performance liquid chromatograph (HPLC) sample vials.
2. Dry the sample vials under a stream of helium.
3. Add 1 mL of the appropriate vehicle (or HPLC mobile phase for .5 standards).
4. Sonicate the vials one hour to dissolve the prostaglandin.
5. Run initial HPLCassays.
6. Place the 1-iPLC sample vials into 20cc scintillation vials with several mLs of deionized water and cap tightly. (Note: This prevents loss due to evaporation.) Standards are stored with HPLC mobile phase in the scintillation vial.
7. Place the vials in the appropriate controlled temperature ovens and reassay periodically by 1-1PLC. Standards are stored in a refrigerator.
