Roberts Pharmaceutical Corporation In Late-Stage Development of A Long-Duration LHRH-Implant For Prostate Cancer

       Separately The Company Anticipates Fourth Quarter 1998 Revenues
                              At A Record Level

    EATONTOWN, N.J., Feb. 8 /PRNewswire/ -- Roberts Pharmaceutical Corporation
(Amex: RPC) today announced that its new late-stage development product,
designated RL0903, targets the treatment of prostate cancer in the United
States, Canada and Europe, a market estimated at over $2 billion.
    Roberts said it acquired rights from Hydro Med Sciences to a patented
hydrogel implant delivery technology for use in the Phase III development of a
LHRH agonist for the hormonal treatment of prostate cancer.  In consideration
of milestone payments and royalties on future sales, Roberts received
exclusive rights to develop and market this LHRH-Hydrogel Implant for the US,
Canada, and Europe.
    The LHRH agonist, a Roberts' therapeutic, is a synthetic gonadotropic
hormone releasing factor agonist that, due to its long-term inhibition of
pituitary release of gonadotropins, can block both ovarian and testicular
function.  The hydrogel implant employs a proprietary technology that delivers
therapeutic agents at a controlled, constant release rate for up to a year.
It is a retrievable subcutaneous implant that can be inserted in a physician's
office using a local anesthetic.
    The LHRH-Hydrogel Implant offers potentially significant benefits over
standard drug therapies for prostate cancer that employ gonadotropin hormone
releasing agonists and involve administration regimens ranging from low-dosage
daily injections to high-dosage implants or depot injections of 3 to 4-months
duration.  The LHRH-Hydrogel Implant should have distinct advantages by
providing a more potent, reliable administration of smaller amounts of
therapeutic agent over a longer time.
    "RL0903 greatly enriches our development pipeline," said John T.
Spitznagel, Roberts' President and CEO.  "We now have three compounds in or
nearing Phase III development which represent significant future sales
potential for Roberts.  These include Dirame(R), a potent analgesic, and
Emitasol(R), an intranasal anti-emetic which was licensed from RiboGene
(Amex: RBO)."
    Separately Roberts said it is also highly optimistic about its near-term
growth prospects.  "With the additions of Pentasa(R), Agrylin(R), and
ProAmatine(R) to our portfolio of marketed products, Roberts has been
experiencing significant growth," said Mr. Spitznagel.  He concluded by
noting, "We will soon announce year-end 1998 results and expect to report that
in the fourth quarter of the year Roberts achieved, by a wide margin, a record
level of revenues."
    Roberts Pharmaceutical Corporation, with operating subsidiaries in the
United States, Canada and the United Kingdom, focuses on value-added specialty
pharmaceuticals in the therapeutic categories of gastroenterology, urology,
oncology/hematology, and cardiology/neurology.   Roberts actively pursues its
