`Preface to “Recent New Drugs 2001”
`
`During the half-century since 1949, “Recent New Drugs” has annually collated, edited and published
`
`newly approved and newly marketed pharmaceuticals (for medical and non-prescription uses) in the broadest
`possible scope.
`On the occasion of the 50th anniversary of the inaugural issue in 2000, the character of a “new drug
`
`yearbook” introducing pharmaceuticals newly put on the market during the previous year was more sharply
`defined, and a new start was made by updating listing methods, classifications, and appearance, as well as
`enlarging the format to B5-size. “Recent New Drugs 2001” – the second volume since the relaunch – is an
`introductory new drug yearbook which collects, classifies, and arranges in the broadest possible scope the new
`drugs (for medical and non-prescription uses) that were approved and newly marketed during the previous year
`(2000) within Japan.
`
`Editorial guidelines are as follows.
`1. Classification method
`
`Listed pharmaceuticals are broadly classified into: I. pharmaceuticals containing new active ingredients
`(new substances) (excluding new administration routes and new standards); II. newly marketed
`pharmaceuticals for medical use (excluding the pharmaceuticals containing new active ingredients of I); and
`III. non-prescription pharmaceuticals. Medical-use pharmaceuticals are arranged by pharmacoefficacy
`classification in conformity with the Japan Standard Commodity Classification (June 1990 Revision), and non-
`prescription pharmaceuticals broadly conform to the order of the “Standards for manufacturing (importation)
`approval of non-prescription pharmaceuticals” with suitable adjustments.
`2. Listing system
` With respect to pharmaceuticals containing new active ingredients, not only are package inserts (including
`reference literature) recorded for the pertinent pharmaceuticals, but also the development background,
`reexamination period, basis for drug price calculation, and so on.
` With respect to other medical-use pharmaceuticals, there is listing of efficacy/effects, usage/dosage,
`foreign name of pertinent product, regulation, manufacturing (import sales) origin / sales (marketing) origin,
`approval date, sales initiation date, date of price listing, price standard listing pharmaceutical code, and
`packaging, and this is done by unit of generic name classified/arranged in the order of pharmacoefficacy
`classification.
`
`Beginning with this issue, we have created a page for introducing pharmaceuticals with newly added
`efficacies (medical-use pharmaceuticals that have been given added efficacy during January-December 2000).
` With respect to non-prescription pharmaceuticals, there is listing of manufacturing (import sales) origin /
`sales (marketing) origin, approval date, sales initiation date, product characteristics, ingredients and quantities,
`additives, usage/dosage, and packaging.
`3. Descriptive content
`
`“Cautions for use” pertaining to pharmaceuticals containing new active ingredients are in principle
`recorded as in the description of the package insert, and are omitted with respect to other new drugs. The
`method for tracing to back numbers of this publication was discontinued. The so-called commentary up to the
`50th compilation is not included in the editing of package insert compliance.
`
`As described above, publication was made as a “new drug yearbook” of what was newly approved and
`marketed over a one-year period, and we await the comments and requests of all our readers with respect to
`this volume.
`
`This volume was edited based on the studies and information gathering conducted by our company with
`respect to the various pharmaceutical manufacturing / sales (marketing) companies. Hereafter, we will request
`a still greater number of pharmaceutical companies to cooperate with our studies.
`
`Finally, we would like to express our deep gratitude to all our readers and all the pharmaceutical
`companies that have cooperated with our studies over this past half-century to the present, and to Tohoku
`University Honorary Professor Mitsuru Ozawa who has written for us over the half century since the inaugural
`issue, and who also provided useful advice on the occasion of this edition.
` We appeal for the cooperation and support of everyone as we seek to further enhance this publication.

`
`[Development background]
` With respect to treatment of ocular inflammation,
`both steroidal ophthalmic agents and non-steroidal
`anti-inflammatory drug (NSAID) ophthalmic agents
`are currently in general use. However, compared to
`steroidal ophthalmic agents, there are fewer types of
`NSAID ophthalmic agents, and options are limited.
`Thus, development of NSAID ophthalmic agents
`having broad efficacy and strong anti-inflammatory
`action relative to inflammatory ailments of the
`external eye and anterior eye is desirable.
` Bromfenac sodium hydrate which is the active
`ingredient of Bronuck ophthalmic solution was
`discovered by A.H. Robins Co. (now Wyeth-Ayerst
`Co.) as a novel NSAID that powerfully inhibits
`production of prostaglandin which is an inflammatory
`mediator. By modifying bromine at the 4th position of
`the benzoyl group of Amfenac, which is the basic
`skeleton,
`this drug strives
`to
`reinforce anti-
`inflammatory action and sustain analgesic action.
` Focusing on this strong prostaglandin production
`inhibiting
`action, Senju Pharmaceutical Co.
`proceeded with development of this drug from 1987.
`Bronuck ophthalmic solution was approved in March
`2000 as a symptomatic therapeutic agent that is
`effective at two ocular instillations per day with
`respect
`to blepharitis,
`conjunctivitis,
`scleritis
`(including
`episcleritis),
`and
`postoperative
`inflammation.

`postoperative inflammation)
`[Usage /dosage]
` Ordinarily, 1-2 drops per administration, and 2
`ocular instillations per day.
`[Cautions for use]
`1. Important basic cautions
`(1) Keeping in mind that treatment by this drug is
`symptomatic treatment rather than causal treatment,
`and that it is reported that serious liver damage
`(including death) has been observed in patients
`subjected to long-term administration of 1 month or
`more with the oral agent of bromfenac sodium,
`continuous administration of 4 weeks or more is in
`principle not conducted. Although the aforementioned
`adverse effects observed with the foreign oral agent
`were due to long-term administration exceeding the
`approved usage and dosage, sales have been
`voluntarily suspended.
`(2) As there is risk that eye infection may become
`inapparent, in case of use on inflammation resulting

`3. Administration to pregnant, parturient, and
`nursing women
` Administration is to be conducted to pregnant
`woman or women who may have conceived and to
`women who are nursing only when it is judged that
`the benefits of treatment outweigh the risks.
`(The safety of administration during pregnancy and
`lactation has not been established.)
`4. Administration to children
` Safety relative to children has not been established
`(there is little experience with use).
`5. Cautions for use
`(1) Administration route: only to be used for ocular
`installation
`(2) At
`time of administration: during ocular
`installation, take care so that the tip of the container
`does not directly contact the eye.

`Intraocular migration <rabbits>1)
` In testing wherein ocular installation of 0.05 mL of
`0.1% 14C-bromfenac sodium hydrate ophthalmic
`solution was conducted once a day to both eyes of a
`rabbit, and radioactivity was measured after 15
`minutes, 30 minutes, and 1, 2, 4, 8, 12, 24, 48, and 72
`hours, elevated values were observed in the cornea,
`conjunctiva, and anterior sclera.
` At 72 hours after ocular installation, all ocular
`tissue except for the lens was below the detection
`limit (0.1 ng eq./g or ml).

`1. Pharmacological action
`(1) Experimental anti-inflammatory action relative to
`conjunctival chemosis in rats2)
`It was observed that Bronuck ophthalmic solution
`exhibited anti-inflammatory action
`relative
`to
`experimental acute conjunctival chemosis in rats
`induced by arachidonic acid and carrageenin.
`(2) Inhibitory effects relative to increases in aqueous
`humor protein concentration in rabbits after anterior
`chamber paracentesis or after laser irradiation2)
`It was observed that Bronuck ophthalmic solution
`almost completely inhibited increases in aqueous
`humor protein concentration in rabbits after anterior
`chamber paracentesis or after laser irradiation.
`2. Mechanism of action
`In tests using rabbit iris-ciliary bodies2) and bovine
`seminal vesicles, it was confirmed that inhibitory
`action was
`exhibited
`against production of
`prostaglandin
`inflammatory
`mediators
`via
`cyclooxygenase (in vitro).
