preferred stock purchase rights ("Common Stock"), $0.005 par value per share, of
Encysive Pharmaceuticals Inc., a Delaware corporation ("Encysive" or the
"Company").


ITEM 1.     SECURITY AND ISSUER.


        The title and class of equity securities to which this statement on
Schedule 13D relates is the Common Stock of the Company. The Company's principal
executive offices are located at 4848 Loop Central Drive, Suite 700 Houston,
Texas 77081.


ITEM 2.     IDENTITY AND BACKGROUND.


        (a) - (c) and (f) This statement on Schedule 13D is being filed by
Pfizer, a Delaware corporation, and Explorer, a Delaware corporation. Pfizer and
Explorer are sometimes herein referred to collectively as the "Reporting
Persons," and each as a "Reporting Person." The principal executive offices of
Pfizer and Explorer are located at 235 East 42nd Street, New York, NY 10017.
Pfizer is a research-based, global pharmaceutical company. Explorer was formed
by Pfizer to acquire Encysive and has not conducted any unrelated activities
since its organization.

          Set  forth  on  Schedule  I to  this  statement  on  Schedule  13D and
incorporated  herein by reference is the following  information  with respect to
each director and executive officer of Pfizer and Explorer:

          (1)  name;

          (2)  business address;

          (3)  principal  occupation  or  employment  and  the  name,  principal
               business and address of any corporation or other  organization in
               which such employment is conducted; and

          (4)  citizenship

        (d) - (e) During the past five years, neither of the Reporting Persons
nor, to the best knowledge of the Reporting Persons, any of the directors and
executive officers of the Reporting Persons, (1) has been convicted in a
criminal proceeding (excluding traffic violations and similar misdemeanors) or
(2) was a party to a civil proceeding of a judicial or administrative body of
competent jurisdiction and as a result of such proceeding were or are subject to
a judgment, decree or final order enjoining future violations of, or prohibited
or mandating activities subject to, U.S. federal and state securities laws or
finding any violations with respect to such laws.


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


        The information set forth in Section 9 entitled "Source and Amount of
Funds" of the Offer to Purchase (as defined in Item 4) is incorporated herein by
reference.


ITEM 4.     PURPOSE OF TRANSACTION.

        (a) - (j) The Reporting Persons and Encysive entered into an Agreement


                                       4




and Plan of Merger, dated February 20, 2008 (the "Merger Agreement"), for the
purposes of the Reporting Persons' acquisition of all of the issued and
outstanding shares of Common Stock (the "Shares"). Pursuant to the Merger
Agreement, Pfizer and Explorer commenced a tender offer (the "Offer") to
purchase all of the outstanding Shares at a purchase price of $2.35 per Share,
net to the seller in cash, without interest and less any required withholding
taxes, upon the terms and subject to the conditions set forth in the Offer to
Purchase, dated March 4, 2008 (the "Offer to Purchase"), incorporated by
reference from Exhibit (a)(1)(A) of the Tender Offer Statement on Schedule TO
filed by Explorer and Pfizer with the Securities and Exchange Commission (the
"Commission") on March 4, 2008 (as amended, the "Schedule TO"), and the related
Letter of Transmittal, incorporated by reference from Exhibit (a)(1)(B) of the
Schedule TO. After consummation of the Offer, the Merger Agreement provides that
Explorer will be merged (the "Merger") with and into Encysive, with Encysive
surviving the Merger as a wholly-owned subsidiary of Pfizer. Each Share
outstanding immediately prior to the effective time of the Merger (other than
Shares held by Encysive, Pfizer or their wholly-owned subsidiaries, all of which
will be cancelled and retired and shall cease to exist, or by stockholders who
exercise appraisal rights under Delaware law), will be converted in the Merger
into the right to receive $2.35 per Share, without interest and less any
required withholding taxes.

        The information set forth in the sections of the Offer to Purchase
entitled "Summary Term Sheet," "Introduction," "Price Range of Shares;
Dividends," "Certain Effects of the Offer," "Background of the Offer; Past
Contacts or Negotiations," "Purpose of the Offer; Plans for Encysive," "The
Merger Agreement" and "Dividends and Distributions" is incorporated herein by
reference.

        Except as set forth in this statement (including any information
incorporated by reference) and in connection with the transaction described
above, none of the Reporting Persons has any plan or proposal that related to or
would result in any of the transactions described in subparagraphs (a) through
(j) of Item 4 to the Schedule 13D.

ITEM 5.     INTERESTS IN THE SECURITIES OF THE PURCHASER.


        (a) and (b) As a result of purchases of Shares pursuant to the Offer, on
April 11, 2008, Pfizer and Explorer beneficially own an aggregate 67,688,555
shares (the "Shares") of Common Stock, representing 83.61% of the outstanding
shares of Common Stock (based upon 80,955,060 Shares issued and outstanding as
of March 28, 2008, as reported to the Reporting Persons by Encysive). Pfizer and
Explorer each have sole voting and dispositive power of all the Shares by virtue
of the fact that Explorer, the record holder of the Shares, is a wholly-owned
subsidiary of Pfizer.


        (c) On April 1, 2008, Explorer accepted 61,765,295 Shares for purchase,
representing the number of Shares properly tendered and not withdrawn as of the
initial expiration date for the Offer (excluding Shares subject to notices of
guaranteed delivery). Pursuant to the subsequent offering period that is
scheduled to expire on April 14, 2008 at 5:00 p.m., New York City time, as well

purchased the following number of Shares on the following dates at the offer
price of $2.35 per Share:
