                                  INTRODUCTION

         This Statement on Schedule 13D, as originally filed on February 13,
2004, constituted the initial filing for Perrigo Company. This Amendment No. 1
is being filed solely to provide information that was redacted from Exhibit 7.1
of the original filing pursuant to a request for Confidential Treatment that has
now been withdrawn.

ITEM 1. SECURITY AND ISSUER.

         This Schedule 13D, as amended (this "Schedule 13D"), relates to the
common stock, $.001 par value (the "Common Stock") of Lannett Company, Inc. (the
"Issuer"), whose principal executive officers are located at 9000 State Road,
Philadelphia, Pennsylvania 19136.

ITEM 2. IDENTITY AND BACKGROUND.

         This Schedule 13D is filed by Perrigo Company, a Michigan corporation
("Perrigo"), whose principal executive offices are located at 515 Eastern
Avenue, Allegan, Michigan 49010. During the last five years, neither Perrigo,
nor, to the best knowledge of Perrigo, any director or executive officer of
Perrigo or any person controlling Perrigo, has been (a) convicted in a criminal
proceeding (excluding traffic violations or similar misdemeanors) or (b) a party
to a civil proceeding of a judicial or administrative body of competent
jurisdiction and as a result of such proceeding was or is subject to a judgment,
decree or final order enjoining future violations of, or prohibiting or
mandating activities subject to, Federal or State securities laws or finding any
violation with respect to such laws.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         On February 4, 2004, Perrigo entered into a Stock Purchase Option
Agreement (the "Option Agreement") with William Farber and Audrey Farber (the
"Farbers"), pursuant to which Perrigo acquired the option (the "Option") to
purchase certain shares of Common Stock owned by the Farbers (as more fully
described in Item 5 below) for an amount equal to $197,339,000, plus additional
contingent consideration (the "Exercise Price"). The price of the Option was
$180,000, and was funded from Perrigo's cash on hand. In the event that Perrigo
exercises the Option, the price of the Option would be credited to the Exercise
Price and the remainder of the funds required to pay the Exercise Price would be
paid from cash and borrowings yet to be determined.

ITEM 4. PURPOSE OF TRANSACTION.

         Perrigo has acquired the Option in contemplation of acquiring control
of the Issuer. Because of the Farbers' large percentage ownership interest in
the Issuer, if Perrigo exercises the Option, its acquisition of the Common Stock
subject to the Option could lead to any of the actions or consequences noted in
clauses (a) through (j) of Item 4 of Form 13D. Perrigo has represented to the
Farbers that, if it exercises the Option, it will, within 90 days of acquiring
the Common Stock subject to the Option, make a tender offer (to the extent
permitted by law) or alternatively use its commercially reasonable efforts to
enter into a merger agreement or other business combination with the Issuer for
the remainder of the outstanding shares of Common Stock.




ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

         Pursuant to the Option Agreement, Perrigo has the right to acquire
13,519,129 currently issued and outstanding shares of Common Stock as well as
37,500 shares of Common Stock issuable to Mr. Farber upon the exercise of
certain in-the-money options owned by him (the "In-the-money Options"). In
connection with Perrigo's exercise of the Option, Mr. Farber is required to
exercise the In-the-money Options. Mr. Farber also currently holds certain other
options (the "Other Options") to purchase 25,000 shares of Common Stock, which
vest in installments beginning on October 14, 2004. Pursuant to the terms of the
Other Options, however, the Other Options may accelerate and become exercisable
immediately upon the grant of the Option and/or the exercise of the Option.
Pursuant to the Option Agreement, Perrigo has the right to direct Mr. Farber to
cause the Issuer to cancel the Other Options or, in the event that the Other
Options are in fact exercisable, to direct Mr. Farber to exercise the Other
Options and convey the issued shares of Common Stock to Perrigo. In the event
that Perrigo exercises the Option and directs Mr. Farber to exercise and convey
the stock subject to the Other Options, Perrigo will acquire 13,581,629 shares
of Common Stock, which will constitute 67.5% of the total issued and outstanding
Common Stock, based on 20,058,374 shares issued and outstanding as of February
4, 2004, as reported in the Issuer's Form 10-Q for the quarter ended December
31, 2003, plus 62,500 shares issuable upon the exercise of the In-the-money
Options and the Other Options.

         Perrigo currently has no power to vote, to direct the vote, to dispose
of, or to direct the disposition of any securities subject to the Option. In the
event that Perrigo exercises the Option and directs Mr. Farber to exercise and
convey the stock subject to the Other Options, it will have the sole power to
vote and to dispose of all 13,581,629 shares of Common Stock subject to the
Option.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
SECURITIES OF ISSUER.

         Except for the Option Agreement, there are no contracts, arrangements,
understandings or relationships (legal or otherwise) between Perrigo and any
person with resect to any securities of the Issuer.

ITEM 7. MATERIAL TO BE FILED AS EXHIBITS.
