          This  Amendment  No. 1 to  Schedule  13D  relates  to shares of Common
Stock,  no  par  value  (the  "Shares"),  of  Inhale  Therapeutic  Systems  (the
"Issuer").  This Amendment No. 1 supplementally  amends the initial statement on
Schedule  13D dated  February  18,  1997,  filed by the  Reporting  Persons (the
"Initial  Statement").  This  Amendment No. 1 is being filed  voluntarily by the
Reporting  Persons to report that as a result of a recent increase in the number
of  outstanding  Shares of the Issuer,  the  Reporting  Persons may no longer be
deemed the beneficial  owners of five percent or more of the outstanding  Shares
of the Issuer  notwithstanding  the fact that the Reporting Persons have sold no
Shares since the date of the last filing. Capitalized terms used but not defined
herein shall have the meanings  ascribed to them in the Initial  Statement.  The
Initial Statement is supplementally amended as follows.


Item 2.   Identity and Background.

          This statement is being filed by Soros Fund Management LLC, a Delaware
limited  liability  Company ("SFM LLC"), Mr. George Soros ("Mr.  Soros") and Mr.
Stanley F. Druckenmiller ("Mr. Druckenmiller", and together with SFM LLC and Mr.
Soros, the "Reporting  Persons").  This statement relates to Shares held for the
account of Quantum Partners.

          Updated  information  concerning the Managing  Directors of SFM LLC is
attached hereto as Annex A and incorporated herein by reference.

Item 5.   Interest in Securities of the Issuer.

          (a)  Each of the Reporting  Persons may be deemed the beneficial owner
of the 750,000  Shares held for the account of Quantum  Partners  (approximately
4.91% of the total number of Shares outstanding).

          (b)  (i)  Pursuant to the terms of the contract  between  Quantum Fund
and SFM LLC,  SFM LLC may be deemed to have sole  power to direct the voting and
disposition of the 750,000 Shares held for the account of Quantum Partners.

               (ii) Pursuant to the terms of the contract  between  Quantum Fund
and  SFM  LLC  and as a  result  of the  positions  held  by Mr.  Soros  and Mr.
Druckenmiller  with SFM LLC,  each of Mr.  Soros  and Mr.  Druckenmiller  may be
deemed to have shared power to direct the voting and  disposition of the 750,000
Shares held for the account of Quantum Partners.

          (c)       There have been no  transactions  with respect to the Shares
since  February 18, 1997 (the date of the last  filing) by any of the  Reporting
Persons or Quantum Partners.

          (d)       The  shareholders  of Quantum  Partners,  including  Quantum
Fund,  have the right to  participate  in the  receipt  of  dividends  from,  or
proceeds  from the sale of, the Shares held for the account of Quantum  Partners
in accordance with their ownership interests in Quantum Partners.

          (e)       Each of the  Reporting  Persons is no longer the  beneficial
owner of more than 5% of the  outstanding  Shares  because of an increase in the
number  of  outstanding  Shares,  notwithstanding  the fact  that the  Reporting
Persons have not sold any Shares since the date of the last filing.
