ITEM 1. SECURITY AND ISSUER

                This Amendment No. 5 to statement on Schedule 13D (this "Statement") relates to the Common Stock, no par value (the "Common Stock"), of Dendrite International, Inc., a New Jersey corporation (the "Issuer" or the "Company"), the principal executive offices of which are located at 1405 U.S. Highway 206, Bedminster, NJ 07921. This Amendment No. 5 amends and restates in full each of the items set forth below. Terms not defined in this Amendment No. 5 shall have the respective meanings given to such terms in the Schedule 13D originally filed on December 13, 2005 ("Original Schedule 13D").

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

                The total purchase price of the 5,573,900 shares of Common Stock (the "Shares") purchased by MMI Investments was $83,901,353; the source of funds is a combination of MMI's working capital and margin loans. These margin loans were obtained from Bear, Stearns & Co. Inc. and Merrill Lynch & Co. under customary terms and conditions. The entire principal amount of such margin loans remains outstanding as of the date of this Statement.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

    (a)-(b)    Based on 43,552,894 shares of Common Stock outstanding as of March 6, 2006, as reported in the Issuer's Annual Report on Form 10-K for the fiscal year ended December 31, 2005 filed with the SEC on March 16, 2006, the Shares owned by MMI Investments represent approximately 12.8% of the outstanding Common Stock. MMI Investments has the sole power to direct the vote and disposition of such Shares on the date of this Statement. However, by virtue of being the general partner of MMI Investments, MCM may be deemed to be the beneficial owner of the Shares owned by MMI Investments and to have sole power over the voting and disposition of such Shares as a result of its having the sole power to make voting and disposition decisions on behalf of MMI Investments with respect to such Shares.

                Except for the Shares owned by MMI Investments, as of the date hereof, neither MCM nor, to MMI Investments' and MCM's knowledge, any of the persons listed on Schedule I, owns any Common Stock of the Issuer or has any right to acquire, directly or indirectly, any beneficial ownership of other Common Stock of the Issuer.

    (c)        Except for the open market purchases of Common Stock by MMI Investments set forth in Schedule II attached hereto and incorporated herein by reference, there have been no transactions with respect to the Common Stock, since the March 2, 2006 filing of Amendment No. 4 to the Original Schedule 13D, by MMI Investments, MCM, or, to either Reporting Person's knowledge, any of the persons listed on Schedule I.

    (d)        No person other than MMI Investments is known to either Reporting Person to have the right to receive or the power to direct the receipt of dividends from or the proceeds from the sale of, any of the Shares referred to in Item 5(a) above.

    (e)        Not applicable.

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

                By virtue of being the general partner of MMI Investments, MCM may be deemed to be the beneficial owner of the Shares of the Issuer owned by MMI Investments. Other than as described in Item 3 of this Statement (and the Joint Filing Agreement filed as an Exhibit to this Statement), there are no contracts, arrangements or understandings between the Reporting Persons or between either of the Reporting Persons and any other person with respect to any securities of the Issuer.
