the composition of the present invention is a medicamentous form or composition in an aqueous or ointment base particularly suitable for opthalmologic , otolaryngologic , and dermatologic application . the medicamentous form contains inhibitors of proteases such as aprotinin , soybean inhibitor of trypsine , and elastatinal having a concentration of substantially 0 . 1 to 20 mg per 1 ml of solution or per 1 g . of ointment base . these inhibitors are applied either individually or in combination after being dissolved in physiological saline or buffer solution with a ph of 6 . 5 to 7 . 5 , which is advantageously ionically balanced ( e . g ., phosphate or borax buffer ) or present in the ointment base . the ionically balanced buffer solution means that sodium chloride is added to the buffer solution in such a way that the 15 resulting solution is ionically balanced . for example , the precise performance for borax buffer with ph 7 . 4 is as follows : solution a -- 1 . 9 g . na 2 p 4 o 7 per 100 ml h 2 o pro injectione solution b -- 1 . 25 g . h 3 bo 3 + 0 . 3 g . nacl per 100 ml h 2 o pro injectione the medicamentous form according to the preferred embodiment in the liquid state may further advantageously contain 0 . 05 to 15 percent by weight of thickeners selected from the group comprising hydroxypropyl methyl cellulose , methyl cellulose , polyvinylpyrrolidone , polyvinyl alcohol , poly ( alkylene glycols ), poly / hydroxyalkyl , ( meth ) acrylates or poly ( meth ) acrylamides . high concentrations of aprotinin , or another inhibitor , when locally applied , act not only curably in the advanced stage of disease but also prospectively by the prevention of the formation of destructive processes if timely administered . the vehicles or thickeners with protracted effect then enable a longer contact of the remedy ( e . g ., aprotinin ) with the tissues . the combination of aprotinin with other inhibitors , such as 10 elastatinal or inhibitors from soybeans , enhances the therapeutical effect . the medicamentous form according to the preferred embodiment may contain 0 . 05 to 1 . 5 percent by weight of steroidal antiphlogistics such as indomethacin or 0 . 2 to 1 percent by weight of antibiotics such as bacitracin , neomycin , tetracycline , or chloramphenicol . the combination of protease inhibitors with antiphlogistics or antibiotics , or all substances together , increases the antiinflammatory and anti - microbial effect because the inhibitors block some products of microbes such as elastase or other proteases . this enables one to use the antibiotics only locally and in smaller doses . the concentration of antiphlogistics may be reduced and , at the same time , the therapeutic effect is higher and the time of treatment shorter which is of great value in healing of tissue . the medicamentous form is most often applied by instillation or as an ointment into the conjunctival sac . however , it can also be used for irrigation or lubrication of the eye , facial sinuses , and external auditory meatus . it may also be injected into the anterior eye chamber and other places . the medicamentous form in the liquid state may be also present in a hydrophilic three - dimensional polymer matrix in the form of a strip , contact lens , and the like from which the active components are released . the incorporation of medicamentous form into a hydrophilic matrix can be performed according to the invention by conditioning of the matrix in the solution of the medicamentous form in order to obtain the required concentration of inhibitors and also for the antiphlogistics and antibiotics in polymer matrix . the invention is illustrated in the examples of performance and the examples are provided without the intention of limiting the scope of the present invention . the preparation of medicamentous form in liquid state is begun by separately dissolving each substance in a small amount ( 10 to 40 ml ) of buffer or physiological saline . the ointment base is prepared by melting 10 g . lanolin , 10 g . liquid paraffin , and 80 g . white vaseline in bath water . the mixture is then strained through a hydrophilic gauze and sterilized . if the applicable therapeutic is easily soluble in water , it is dissolved in the necessary amount of distilled water for the preparation of injections , mixed with the ointment base in part melted in a water bath and stirred until completely cooled . if the therapeutic is insoluble in water , it is used for the preparation in the finest powdered form . however , it is first titrated in a smaller amount of liquid paraffin and then mixed with the ointment base . a mixture is provided by combining aprotinin 0 . 01 g . ;
