This Amendment No. 1 to Schedule 13D (this "Amendment No. 1") is being filed

Item 2. Identity and Background.

                                       5



investment discretion over securities held by Strategic Partners. Mr. Feinberg

     (f) Strategic Partners is organized under the laws of the Cayman Islands.
Strategic Capital is organized under the laws of the State of Delaware. Mr.

Item 3. Source and Amount of Funds or Other
        Consideration.

     A series of transactions involving the Company were described in the
Company's Current Report on Form 8-K, filed on December 27, 2002 (the "Form
8-K"). In connection with these transactions, Strategic Partners received
additional securities of the Company by operation of certain anti-dilution
adjustments with respect to warrants to purchase Common Stock ("Warrants") that
it directly owned. Specifically, Warrants theretofore entitling Strategic
Partners to purchase 1,010,100 shares of Common Stock, at an exercise price of
$1.404, were adjusted to represent Warrants for 2,393,478 shares of Common Stock
with an exercise price of $0.59. In addition, Warrants theretofore entitling
Strategic Partners to purchase 1,010,100 shares of Common Stock, at an exercise
price of $2.285, were adjusted to represent Warrants for 2,393,478 shares of
Common Stock with an exercise price of $0.96. These two sets of Warrants were
then exchanged, in a cashless exercise (as valued pursuant to a Black-Scholes
model), for 1,895,824 and 1,753,637 shares of


                                       6



Common Stock, respectively, or 3,649,461 shares in the aggregate.

     In connection with the transactions described in the Form 8-K, existing 5%
convertible senior secured debentures ("Debentures") held by Strategic Partners
were amended to extend their maturity date to March 31, 2006 and their
applicable conversion prices for conversion into Common Stock were revised in
accordance with their anti-dilution provisions. Strategic Partners holds
Debentures in the principal amounts of: $10,000,000; $125,000; $126,562;
$128,144; $129,746; $131,368; $133,010; $134,672; $136,356; $138,060; $139,786;
$141,534; and $143,302. The conversion prices for such Debentures per share of
Common Stock are, respectively, $0.6135, $0.7525, $0.4862, $0.3964, $0.2735,
$0.4501; $0.9701, $0.9701; $0.8128; $0.8827; $0.7516; $0.7667; and $1.0200. The
Debentures are therefore convertible, respectively, into the following amounts
of Common Stock: 16,298,644; 166,110, 260,238; 323,268; 474,436; 291,858;
137,104; 138,818; 167,756; 156,400; 185,974; 184,598; and 140,492. The foregoing
Debentures, except for the $10,000,000 initial Debenture, were received by
Strategic Partners as interest payments. Interest on all the Debentures held by
Strategic Partners is paid quarterly on each January 1, April 1, July 1 and
October 1. The Debentures are convertible at any time, at the option of their
holder, into Common Stock.

     Strategic Partners also has acquired options exercisable for 30,000 shares
of Common Stock (the "Options") at no additional cost as compensation for the
services of Mr. Joel Liffmann ("Mr. Liffmann") as a member of the board of
directors of the Company. Mr. Liffmann is a general partner of an affiliate of
Strategic Partners.

     Strategic Partners, Strategic Capital and Mr. Feinberg may be deemed to
beneficially own the Common Stock received in exchange for the Warrants
previously held by Strategic Partners, and also the underlying Common Stock
which may be acquired upon conversion or exercise of the foregoing Debentures
and Options owned by Strategic Partners. The source of the initial amounts paid
for these securities, all of which were acquired in privately negotiated
transactions, was the working capital of Strategic Partners. Strategic Partners
contributed no additional funds to the Company in connection with the events
described in the Form 8-K, but did surrender certain documents which reflect the
previously held


                                       7



Debentures for new documents representing the revised conversion prices and
maturity dates, as set forth above. Strategic Partners initially paid to the
Company $10,000,000 to acquire the Debentures and Warrants it held.

Item 4. Purpose of Transaction.

     The shares of Common Stock deemed to be beneficially owned by Strategic
Partners, Strategic Capital and Mr. Feinberg were acquired for, and are being
held for, investment purposes. The securities which are convertible into or
exchangeable for shares of Common Stock were acquired in the ordinary course of
business and not for the purpose of acquiring control of the Company.

     The Reporting Persons may in the future directly acquire shares of Common
Stock in open market or private transactions, block purchases or otherwise. The
Reporting Persons may continue to hold or dispose of all or some of the
securities reported herein from time to time, in each case in open market or
private transactions, block sales or purchases or otherwise, subject to
compliance with applicable law. In that regard, pursuant to that certain
Registration Rights Agreement incorporated herein by reference as Exhibit 8, the
Reporting Persons are entitled to certain registration rights with respect to
the Common Stock to permit the public sale thereof in accordance with the
Securities Act of 1933, as amended, and applicable state securities laws. Other
than as set forth herein, none of the Reporting Persons has any plans or
proposals which relate to, or could result in, any of the matters referred to in
paragraphs (b) through (j), inclusive, of Item 4 of Schedule 13D. Each of the
Reporting Persons may, at any time and from time to time, review or reconsider
his or its position and formulate plans or proposals with respect thereto, but
has no present intention of doing so.

Item 5. Interest in Securities of the Issuer.

     (a) As of the close of business on February 25, 2003, the Reporting Persons
were the beneficial owners, within the meaning of Rule 13d-3 under the Exchange
Act, of 22,605,245 shares of Common Stock. As of that date, these shares
represented 56.5% of the sum of (i) the 21,035,323 total shares of Common Stock
outstanding as reported to Strategic Partners by the Company's chief financial
officer and (ii) the 18,955,784 shares of Common Stock which would


                                       8



be received by Strategic Partners upon conversion or exercise of the Debentures
and Options which it holds.

     (b) The sole or shared power to vote or dispose of, or to direct the vote
or disposition of the Common Stock with respect to each Reporting Person noted
in paragraph (a) of this Item 5 is as set forth on the cover sheets of this
Amendment No. 1.

     Strategic Capital does not directly own any Common Stock. Strategic Capital
may be deemed to beneficially own 22,605,245 shares of Common Stock by virtue of
the investment discretion it exercises over Strategic Partners as general
partner.

     Mr. Feinberg does not directly own any Common Stock. Mr. Feinberg may be
deemed to beneficially own 22,605,245 shares of Common Stock by virtue of his
control over the business activities of Strategic Capital as managing member.

     (c) The holdings of the Reporting Persons with respect to securities of the
Company consist solely of the shares of Common Stock, Debentures and Options
described above. Except as disclosed above, there have been no transactions
involving the shares of Common Stock of the Company engaged in during the period
beginning 60 days prior to December 20, 2002 and ending on the date hereof.

     (d) No other person is known to have the right to receive or the power to
direct the receipt of dividends from, or proceeds from the sale of, the
securities reported herein, other than the partners of Strategic Partners, none
of whom individually has such right or power with respect to in excess of 5% of
the total outstanding Common Stock.

Item 6. Contracts, Arrangements, Understandings or
        Relationships with Respect to Securities of the
        Issuer.

     Strategic Partners is a party to that certain Debenture and Warrant
Purchase Agreement dated May 26, 1999 (the "Oracle Purchase Agreement") by and
among the Company, Strategic Partners and the other investors listed therein,
and is also a party to the amendment of the Oracle Purchase Agreement, dated
December 20, 2002. The Oracle Purchase


                                       9



Agreement and its amendment are incorporated herein by reference as Exhibits 2
and 3.

     The Debentures held by Strategic Partners are also governed by the terms
and provisions set forth in the documents or instruments constituting such
debentures. A Form of Debenture is incorporated herein by reference as Exhibit
4. The Debentures provide that Interest thereon shall be paid in the form of
additional Debentures, to be paid quarterly on each January 1, April 1, July 1
and October 1.

     The Options are governed by the terms of the Halsey Drug Co., Inc. 1998
Stock Option Plan, incorporated herein by reference as Exhibit 5, and are
evidenced by option agreements substantially similar to the Form of Option
Agreement attached hereto as Exhibit 6.

     The Warrants held by Strategic Partners were exchanged for Common Stock, as
described herein, in accordance with the Warrant Recapitalization Agreement,
dated December 20, 2002, incorporated herein by reference as Exhibit 7.

     Associated with the Debentures held by Strategic Partners are certain
registration rights, as set forth in the Registration Rights Agreement, dated
December 20, 2002, incorporated herein by reference as Exhibit 8. This
Registration Rights Agreement sets forth registration rights which supercede
rights that Strategic Partners held through prior agreements with the Company.
Under the Registration Rights Agreement, holders of 20% of the registrable
securities may request two demand registrations on Form S-1 and unlimited demand
registrations on Form S-3. In addition to other customary provisions, the
Registration Rights Agreement provides holders of registrable securities
"piggyback" rights on Company registrations.

     Strategic Partners had previously entered into a Voting Agreement, dated
