This is what I use:

(defun remove-LaTeX-command  (befehl)
"removes simple LaTeX command (not starred and without opt. args)
  and the surrounding braces"
(interactive "scommand (without the backslash): ")
(save-excursion
  (goto-char (point-min))
  (while
      (re-search-forward (concat "\\\\" befehl "{") nil t)
    (replace-match "{")
    (save-excursion
      (goto-char (TeX-find-balanced-brace))
      (delete-char -1))
    (delete-char -1))))

best regards
