               This Statement on Schedule 13D relates to shares of Common Stock,
no par value (the "Shares"), of Inhale Therapeutic Systems (the "Issuer").  This
Statement is being filed by the Reporting  Persons (as defined herein) to report
recent  acquisitions  of Shares of the Issuer as a result of which the Reporting
Persons  may be  deemed  to be the  beneficial  owners  of  more  than 5% of the
outstanding Shares.

Item 1.        Security and Issuer.

               This  Statement  relates  to  the  Shares.  The  address  of  the
principal executive offices of the Issuer is 1001 East Meadow Circle, Palo Alto,
California 94303.

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 (as defined herein).

               The business of SFM LLC is managed through a Management Committee
(the "Management  Committee")  comprised of Mr. Soros, Mr. Druckenmiller and Mr.
Gary Gladstein. SFM LLC, a Delaware limited liability company, has its principal
office at 888  Seventh  Avenue,  33rd  Floor,  New  York,  New York  10106.  Its
principal  business  is  to  serve,  pursuant  to  contract,  as  the  principal
investment  manager to several foreign investment  companies,  including Quantum
Partners (the "SFM  Clients").  SFM LLC has been granted  investment  discretion
over  portfolio  investments,  including  the  Shares,  held for the  account of
Quantum  Partners  LDC,  a Cayman  Islands  exempted  limited  duration  company
("Quantum  Partners")  and Quantum Fund N.V.,  a  Netherlands  Antilles  company
("Quantum  Fund").  Quantum  Partners is the principal  operating  subsidiary of
Quantum Fund. Each of Quantum Fund and Quantum Partners has its principal office
at Kaya  Flamboyan  9,  Willemstad,  Curacao,  Netherlands  Antilles.  SFM LLC's
contracts with the SFM Clients generally provide that SFM LLC is responsible for
designing and implementing the SFM Clients' overall investment  strategies;  for
conducting  direct  portfolio  management  strategies to the extent that SFM LLC
determines  that it is  appropriate  to  utilize  its own  portfolio  management
capabilities; for selecting, evaluating and monitoring other investment advisors
who manage separate portfolios on behalf of the SFM Clients;  and for allocating
and reallocating the SFM Clients' assets among the outside managers and itself.

               Mr. Soros,  as Chairman of SFM LLC, has the ability to direct the
investment  decisions  of SFM LLC and as such may be deemed  to have  investment
discretion  over  the  Shares  held for the  accounts  of the SFM  Clients.  Mr.
Druckenmiller,  as Lead Portfolio  Manager of SFM LLC, has the ability to direct
the investment decisions of SFM LLC and as such may be deemed to have investment
discretion  over the Shares held for the accounts of the SFM Clients.  Set forth
in Annex A hereto and  incorporated  by reference in response to this Item 2 and
elsewhere in this Schedule 13D as applicable is a list of the Managing Directors
of SFM LLC (the executive officers of SFM LLC).

               The principal  occupation of Mr. Soros, a United States  citizen,
is his  direction  of the  activities  of SFM LLC,  which is carried  out in his
capacity as Chairman of SFM LLC at SFM LLC's principal office.






                                                              Page 6 of 14 Pages

               The principal  occupation of Mr.  Druckenmiller,  a United States
citizen,  is  his  position  as  Lead  Portfolio  Manager  and a  Member  of the
Management  Committee  of SFM LLC,  which is carried out at SFM LLC's  principal
office.

               Pursuant to  regulations  promulgated  under Section 13(d) of the
Act,  SFM LLC,  Mr.  Soros,  in his  capacity as  Chairman  of SFM LLC,  and Mr.
Druckenmiller, in his capacity as Lead Portfolio Manager of SFM LLC, each may be
deemed a beneficial owner of the Shares held for the account of Quantum Partners
as a result of the  contractual  authority  of SFM LLC to  exercise  voting  and
dispositive power with respect to such Shares.

               During  the  past  five  years,  none of the  Reporting  Persons,
Quantum Partners and, to the best of the Reporting Persons' knowledge, any other
person  identified  in  response  to this  Item 2 has  been (a)  convicted  in a
criminal proceeding, or (b) a party to any civil proceeding as a result of which
it or he has been subject to a judgment,  decree or final order enjoining future
violations  of, or prohibiting  or mandating  activities  subject to, federal or
state securities laws, or finding any violation with respect to such laws.

Item 3.        Source and Amount of Funds or Other Consideration.

               Quantum Partners  expended  $13,500,000 of its working capital to
purchase the Shares reported herein as being acquired in the last 60 days.

               The Shares reported herein were acquired pursuant to the terms of
Stock Purchase Agreement dated January 28, 1997 (the "Stock Purchase Agreement")
between the Issuer and Quantum Partners, a form of which is Exhibit D hereto and
incorporated  herein by  reference.  The terms of the Stock  Purchase  Agreement
described  below are qualified in their  entirety by the specific  provisions of
such agreement. Under the Stock Purchase Agreement, Quantum Partners' obligation
to purchase the Shares was conditioned  upon a registration  statement  covering
the Shares becoming  effective under the Securities Act of 1933, as amended (the
"Securities Act"). On February 7, 1997, the Issuer's  registration  statement on
Form S-3 covering such Shares was declared  effective  under the Securities Act,
and on the same date Quantum Partners paid the Issuer the purchase price for the
Shares. In the Stock Purchase Agreement, Quantum Partners made certain covenants
to the Issuer in which Quantum Partners agreed to certain provisions relating to
the transfer of the Shares,  which  provisions  were intended to ensure that any
such transfer would be in compliance with the Securities Act.

               The Shares held for the accounts of Quantum Partners and/or other
SFM Clients may be held through margin accounts  maintained with brokers,  which
extend margin  credit as and when  required to open or carry  positions in their
margin  accounts,  subject  to  applicable  federal  margin  regulations,  stock
exchange rules and such firms' credit policies.  The Shares which may be held in
the margin  accounts are pledged as  collateral  security  for the  repayment of
debit balances in the respective accounts.

Item 4.        Purpose of Transaction.

               All of the Shares  reported herein as having been acquired for or
disposed of from the account of Quantum  Partners  were  acquired or disposed of
for investment purposes. Neither Quantum Partners, the Reporting Persons nor, to
the best of their knowledge, any of the other individuals identified in response
to Item 2, has any plans or  proposals  that relate to or would result in any of
the  transactions  described  in  subparagraphs  (a)  through  (j) of  Item 4 of
Schedule 13D.

               Mr.  Soros,  Mr.  Druckenmiller  and SFM LLC reserve the right to
acquire,  or cause to be  acquired,  additional  securities  of the  Issuer,  to
dispose of, or cause to be disposed, such securities at any time or to formulate
other  purposes,  plans  or  proposals  regarding  the  Issuer  or  any  of  its
securities,  to the extent deemed  advisable in light of general  investment and
trading policies of the SFM Clients, market conditions or other factors.

Item 5.        Interest in Securities of the Issuer.

               (a) Each of SFM  LLC,  Mr.  Druckenmiller  and Mr.  Soros  may be
deemed  the  beneficial  owner of the  750,000  Shares  held for the  account of
Quantum   Partners   (approximately   5.50%  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) Except for the  transactions  described  in Item 3 and Item 6
hereof,  there  have been no  transactions  with  respect  to the  Shares  since
December  20,  1996 (60 days prior to the date  hereof) 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) Not applicable.

Item 6.        Contracts,  Arrangements,  Understandings  or Relationships  with
               Respect to Securities of the Issuer.

               As disclosed in Item 3 hereto, in connection with its acquisition
of the Shares reported herein,  Quantum Partners entered into the Stock Purchase
Agreement attached hereto as Exhibit D and incorporated herein by reference.

               From time to time each of the Reporting Persons, Quantum Partners
and/or  other SFM Clients may lend  portfolio  securities  to brokers,  banks or
other financial  institutions.  These loans  typically  obligate the borrower to
return the  securities,  or an equal amount of securities of the same class,  to
the lender and  typically  provide  that the  borrower  is  entitled to exercise
voting rights and to retain  dividends during the term of the loan. From time to
time to the extent permitted by applicable law, each of such persons or entities
may borrow securities,  including the Shares, for the purpose of effecting,  and
may effect, short sale transactions, and may purchase securities for the purpose
of closing out short positions in such securities.

               Except  as set  forth  herein,  the  Reporting  Persons,  Quantum

understandings or relationships with respect to any securities of the Issuer.
