                QUINTILES REPORTS 1st QUARTER 2002 EPS OF $0.14,
                    CASH FLOW FROM OPERATIONS OF $55 MILLION

RESEARCH TRIANGLE PARK, N.C. - April 17, 2002 - Quintiles Transnational Corp.
(Nasdaq: QTRN) today announced financial results for first quarter 2002.
Earnings per share for the quarter ended March 31, 2002, were $0.14 on a diluted
basis, meeting analysts' consensus expectations and a 133% increase from first
quarter 2001 reported earnings per share of $0.06. Total net revenues and net
income for first quarter 2002 were $398.1 million and $17.3 million,
respectively, compared to $403.6 million and $7.8 million for first quarter
2001.

"I'm pleased with the progress we made during the quarter in delivering core
services and executing our business plan, in particular, continued improvements
in efficiency and positioning ourselves to create greater opportunities in
Product Development and Commercialization," said Quintiles Chief Executive
Officer Pam Kirby, Ph.D. "One such example is our strategic agreement with Kos
Pharmaceuticals to commercialize Advicor(TM) and Niaspan(R) in the U.S. to treat
cholesterol disorders. Also, we enhanced our product partnering expertise and
capabilities through the assets we acquired from Bioglan Pharma Inc. Combined
with our PharmaBio Development group's ability to innovate, I believe we offer
customers the industry's widest range of solutions to help develop and
commercialize drugs and manage product portfolios.

"Another event of note during the quarter was our announcement that our
Quintiles Informatics unit would be combined into a joint venture with McKesson.
Through this venture, which we expect to close this quarter, Quintiles will
retain access to the Informatics unit's unique data products, while furthering
our goal of expanding the use of longitudinal patient-level data to improve
healthcare."

Quintiles Transnational Chief Financial Officer Jim Bierman said: "Our efforts
to improve efficiency continue to pay off, as indicated by the strong cash flow
from operations we achieved during the quarter - $55 million - and our record
decrease in net billings outstanding to 37 days in first quarter 2002 from 46
days in first quarter 2001."

In other first quarter developments, Quintiles repurchased 290,000 shares of its
common stock for an aggregate price of approximately $4.8 million as part of its
previously announced stock repurchase program.

As required, Quintiles adopted the guidance of recently issued accounting
pronouncement EITF 01-14, effective Jan. 1, 2002, and, accordingly, has
reclassified reimbursed service costs as part of revenues.
