1.   Summary of Significant Accounting Policies
     ------------------------------------------

Basis of Presentation
---------------------
Roberts Pharmaceutical Corporation is an international
pharmaceutical company which licenses, acquires, develops and
commercializes post-discovery drugs in selected therapeutic
categories.  The Company currently markets approved pharmaceutical
products in the United States, Canada, the United Kingdom and
several other European countries.  The consolidated financial
statements include the accounts of Roberts Pharmaceutical
Corporation and its majority-owned subsidiaries.  All significant
intercompany transactions are eliminated.  All dollar amounts are
presented in thousands, except for earnings per share.

Foreign Currency Translation
----------------------------
Effective January 1, 1997, the functional currency of the United
Kingdom subsidiary, Monmouth Pharmaceutical, Ltd., was changed from
the U.S. Dollar to the British Pound.  Monmouth's translation gains
and losses are accumulated as a separate component of Shareholders'
Equity.

New Accounting Pronouncements
-----------------------------
Statement of Financial Accounting Standards No. 130, "Reporting
Comprehensive Income" (SFAS No. 130), establishes standards for
reporting and display of comprehensive income and its components
(revenues, expenses, gains, and losses) in a full set of general-
purpose financial statements.  This Statement requires that all
items that are required to be recognized under accounting standards
as components of comprehensive income be reported in a financial
statement that is displayed with the same prominence as other
financial statements.

This Statement requires that a company (a) classify items of other
comprehensive income by their nature in a financial statement and
(b) display the accumulated balance of other comprehensive income
separately from retained earnings and additional paid-in capital in
the equity section of a statement of financial position.

This Statement is effective for fiscal years beginning after
December 15, 1997.  Reclassification of financial statements for
earlier periods provided for comparative purposes is required.

Statement of Financial Accounting Standards No. 131, "Disclosures
about Segments of an Enterprise Related Information" (SFAS No.
131), establishes standards for the way that public business
companies report information about operating segments in annual
financial statements and requires that those companies report
selected information about operating segments in annual financial

                            - 7 -
<PAGE>
statements and requires that those companies report selected
information about operating segments in interim financial reports
issued to stockholders.  It also establishes standards for related
disclosures about products and services, geographic areas, and
major customers.  This Statement supersedes SFAS No. 14, "Financial
Reporting for Segments of a Business Enterprise," but retains the
requirement to report information about major customers.

This Statement is effective for financial statements for periods
beginning after December 15, 1997.  In the initial year of
application, comparative information for earlier years is to be
restated.

The adoption of these Statements will not have an impact on the
Company's consolidated results of operation, financial position or
cash flow.

Reclassification
----------------
Certain items have been reclassified to conform to the current year
presentation.


2.   Inventory
     ---------
Inventory at March 31, 1998 consists of:

          Raw Materials      $ 3,154
          Finished Goods      17,627
                             -------
 
          Total              $20,781
                             =======


3.   Change in Accounting Estimate
     -----------------------------
During the first quarter 1998, management made a change in
accounting estimate in the amount of $1.0 million relating to the
accrual of rebates for a product to which Roberts has sole United
States distribution rights.

Item 2.   Management's Discussion and Analysis of Financial
          Conditions and Results of Operations

Results of Operations
Three months ended March 31, 1998 and 1997

Corporate Revenues
------------------
Total revenue for the three months ended March 31, 1998 increased
$6.5 million as compared with the first three months of 1997.  This
increase was principally due to an increase in revenues from
product sales, however with the addition of Roberts manufacturing
facility during the second half of 1997, there is now a contract
manufacturing revenue component included in corporate revenue.

Product Sales
-------------
For the three months ended March 31, 1998, product sales increased
$6.2 million from $26.3 million to $32.5.

U.S. product sales increased $6.2 million from $17.8 million to
$24.0 million. PROAMATINE provided $2.4 million of this increase,
NOROXIN provided $2.7 million and SLOWMAG showed a net increase
over NORETHIN of $0.9 million.  Sales of the Company's United
Kingdom subsidiary, Monmouth Pharmaceuticals, Ltd., remained even
with the prior year reporting a $0.05 million increase.  Sales of
the Company's Canadian subsidiary decreased slightly by $0.02
million from $3.21 million to $3.19 million due to negative
currency rate fluctuations.  Product sales in local currency
actually increased over the same period last year.

Contract Manufacturing
----------------------
Outside contract manufacturing performed at Roberts manufacturing
facility amounted to $0.3 million for the three months ended March
31, 1998.  The manufacturing facility, located in Oakville,
Ontario, Canada, was acquired in July 1997 and will continue to
provide outside contract and clinical manufacturing revenue.

Cost of Sales
-------------
For the three months ended March 31, 1998, cost of sales amounted
to 38.4% of product sales, a 5.9 percentage point decrease as
compared to the prior year's comparable period.  This decrease in
cost of sales and corresponding increase in gross profit percentage
is the result of the first quarter 1997 inclusion of a $1.8 million
charge for minimum royalties due to Ortho Pharmaceutical
Corporation for SUPPRELIN sales and the first quarter 1998 $1.0
million credit related to change in estimate for rebates.  The 1997
charge of $1.8 million was partially reversed during the third
quarter 1997 after contract renegotiations substantially reduced
the minimum royalty due.  

                             - 9 -



<PAGE>
Research and Development
------------------------
Research and Development expenses increased $0.8 million to $2.7
million during the three months ended March 31, 1998 as compared to
the comparable prior year period.  This increase is due to an
increased level of expenditure required to support the Company's
development program for STANATE and an increase due to the ongoing
Phase IV MIDODRINE trials offset by a decrease in the cost of
purchased research and development.

Marketing and Administrative Expenses
-------------------------------------
For the three months ended March 31, 1998, Marketing and
Administrative expenses increased $2.6 million from $12.4 million
to $15.0 million.  Marketing expenses increased $0.9 million as a
result of many factors, including $0.3 million attributable to the
1997 initiation of auto and equipment leasing agreements, $0.3
million in sales meetings, and $0.2 million in increased brokers
commissions.

Administrative expense increased $1.7 million from $5.5 million to
$7.2 million.  This increase was due primarily to $1.2 million
increase in compensation cost, however $0.2 million relates to a
distribution cost overlap as Roberts moves from an outside
distribution center to the newly purchased, wholly owned,
distribution facility located in Buffalo Grove, Illinois, and $0.1
million is caused by an increase in goodwill amortization for
products purchased during 1997.

Interest Income and Expense
---------------------------
Interest income increased $0.1 million.  Interest expense increased
by $0.01 million as a result of an increase in long-term debt
related to product acquisitions with the current increase mainly
due to the addition of debt associated with the December 1997
acquisition of SLOWMAG.

Income Taxes
------------
For the three months ended March 31, 1998 and 1997, income tax
expense was calculated using a normal statutory rate for continuing
operations, except for certain taxes related to foreign operations.

The Company has recorded net deferred tax assets of approximately
$17.3 million.  Realization is dependent upon generating sufficient
taxable income to utilize such items.  Although realization is not
assured, management believes it is more likely than not that all of
the deferred tax assets will be realized; however, these assets
could be reduced at any time if estimates of future taxable income
are reduced.


                         - 10 -




<PAGE>
Liquidity and Capital Resources
-------------------------------
Operating activities provided $3.0 million in cash.  The primary
components of cash provided by operating activities were net income
of $2.1 million, which includes $2.1 million of non-cash charges,
offset by a $1.0 million increase in accounts receivable and
increased working capital requirements of $0.2 million.

Investing activities used $8.3 million, comprised primarily of $5.1
million in marketable securities purchases and $3.2 million in
purchases of fixed assets.

Financing activities used $0.3 million, including $4.2 million of
payments on notes payable and payment of $0.2 million of preferred
stock dividends paid partially offset by proceeds from the issuance
of Common Stock.

In April, the Company acquired exclusive U.S. rights to market
PENTASA(r), a patented gastrointestinal drug for ulcerative colitis,
from Hoechst Marion Roussel (HMR).  According to the terms of the
agreement, Roberts has exclusive marketing rights for PENTASA in
the U.S. and a two year supply agreement with HMR.  A $100 million
financing commitment has been signed to facilitate the acquisition.

The Company will use its existing cash and securities balances and
cash generated from operations to fund its operating activities and
its near-term and long-term debt obligations from previous product
acquisitions as well as future acquisitions of new products and
capital improvements scheduled for the Canadian manufacturing
facility.  

Foreign Currency Fluctuations
-----------------------------
Roberts has subsidiary operations outside the United States.  As a
result, Roberts is subject to fluctuations in revenues and costs
reported in United States dollars as a consequence of changing
currency exchange rates, especially rates for the British pound and
Canadian dollar.  Such fluctuations were not material for the first
quarter 1998.

Item 6     EXHIBITS AND REPORTS ON FORM 8K
           REPORTS ON FORM 8K


Date of Report

January 8, 1998     Roberts Pharmaceutical Corporation announced
                    that it has submitted a regulatory application
                    in the U.S. for approval to expand the current
                    indication for AGRYLIN(r) (anagrelide
                    hydrochloride) to include polycythemia vera, a
                    chronic myeloproliferative disorder where an
                    increase in blood platelets in present.  The
                    current approved indication for AGRYLIN is to
                    treat essential thrombocythemia.

                    A Product License Application has been filed
                    with the Medicines Control Agency in the
                    United Kingdom seeking approval to market
                    PROAMATINE(r) (midodrine hydrochloride) for the
                    treatment of orthostatic hypotension by
                    Monmouth Pharmaceuticals, Ltd., a wholly owned
                    subsidiary of Roberts located in Guildford,
                    England who currently markets PROAMATINE in
                    Ireland under the name MIDON(r) for the
                    treatment of orthostatic hypotension.

January 22, 1998    Roberts Pharmaceutical Corporation announced
                    that based on preliminary unaudited data, the
                    Company expects per share earnings for the
                    fourth quarter of 1997 to be in the range of
                    $0.07 to $0.09, significantly exceeding the
                    FIRST CALL(r) consensus estimate of $0.05.

February 5, 1998    Roberts Pharmaceutical Corporation announced
                    that it is voluntarily recalling its 4-ounce
                    size antitussive, decongestant and expectorant
                    product ENTUSS-D Jr. Pediatric Expectorant,
                    due to a labelling error in the adult dosage
                    instructions.  Only 538 bottles of a single
                    lot of product is involved, Lot J960855A. 
                    This labeling error represents a major
                    potential risk to health due to the potential
                    for overdose, which may result in serious
                    adverse health consequences. No
                    patient/pharmacist complaints subsequent to
                    usage since the lot was released in January
                    1997 have been received.

April 9, 1998       Roberts Pharmaceutical Corporation announced
                    that it has acquired a U.S. distribution
                    facility located in Buffalo Grove, Illinois
                    from Novartis Pharmaceutical Company with an
                    experienced management and operational staff
                    in place.  It is estimated that the facility
                    will be fully operational during 1998.  This
                    acquisition complements the purchase of a
                    manufacturing facility in July 1997.

                            - 13 -

April 21, 1998      Roberts Pharmaceutical Corporation announced
                    that it has acquired the exclusive U.S. rights
                    to market PENTASA(r), a patented
                    gastrointestinal drug for ulcerative colitis,
                    from Hoechst Marion Roussel, the
                    pharmaceutical company of Hoechst AG.

                    Roberts expects the first 12 months of PENTASA
                    sales to exceed $40 million.  This would make
                    PENTASA the Company's largest revenue
                    generating drug and one of the highest gross-
                    profit-margin products in Roberts portfolio of
                    marketed pharmaceuticals.  The transaction is
                    expected to be accretive to the Company's 1998
                    income and improve cash flow to help fund an
                    expected substantial increase in R&D
                    investments.  It is anticipated that per share
                    earnings will substantially exceed current
                    estimates.

                    The transaction will involve net payments to
                    Hoechst Marion Roussel totalling approximately
                    $130 million.  Donaldson, Lufkin, Jenrette
                    Securities Corporation is arranging for $100
                    million in financing for the transaction.

April 30, 1998      Roberts Pharmaceutical Corporation announced
                    the cash sale of its subsidiary VRG
                    International to Verum Staticon GmbH of
                    Munich, Germany.  Financial details are not
                    disclosed, but under the terms of the
                    agreement, Roberts will receive cash payments
                    from this transaction over the next twelve
                    months and realize a gain on the sale of this
                    company over its book value.

                    Roberts also announced that it expects to
                    report strong year to year improvements in
                    first quarter 1998 revenues, operating profits
                    and net earnings.  Per share earnings for the
                    first quarter 1998 are expected to exceed the
                    FIRST CALL estimate of $0.05.
