Patricia D. Eubanks, 24, a clinical pharmacist with the U.S. Public Health Service since March, died of a cerebral hemorrhage Friday at Walter Reed Army Medical Center.

She was serving as liaison pharmacist to the O'Malley division of Saint Elizabeths Hospital, where she worked in the intensive treatment, alcoholic and geriatric programs. She helped develop a program for externs at the Howard University pharmacy school for Public Health Service interns.

Miss Eubanks was born in Washington. She moved to Rockville with her family in 1968 and graduated from Robert E. Peary High School.

She attended Florida A & M University in Tallahassee and earned a pharmacy degree from the University of Southern California in 1979.

Miss Eubanks was a member of the American Pharmaceutical Association, the California Pharmaceutical Association and the American Society of Hospital Pharmacists. She had received a number of awards for her work in pharmacy.

She was a member of Millian Memorial United Methodist Church in Rockville.

Survivors include her parents, C. Arthur and Marjoria B. Eubanks, and two brothers, Vernon and Virgil, all of Rockville, and her grandfather, Samuel T. Brooks, of Lumberton, N.C.

The family suggest that expressions of sympathy be in the form of contributions to the United Negro College Fund.
