You can try the following scripts. Change it to suit for your table def.

EXECUTE sp_rename N'[PK_MyTable]', N'[PK_MyTable_old]',  'OBJECT'

CREATE TABLE [dbo].[Temp_MyTable](
[id] [int] NOT NULL,
[text] [text] NOT NULL CONSTRAINT [PK_MyTable] PRIMARY KEY CLUSTERED (
[id] ASC)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON))

INSERT INTO dbo.[Temp_MyTable] (Id, Text)
SELECT Id, Text FROM dbo.MyTable

drop table dbo.MyTable
EXECUTE sp_rename N'Temp_MyTable', N'MyTable', 'OBJECT'
