MARIANO QUE
Mariano Que, the Mercury Drug
Founder, who just passed away, initially
worked as an employee of drug store
chain during the pre-war era.
After the devastation of World War
II, Que knew Filipinos needed
Sulfiathiazole- a “miracle” drug used
to cure many diseases and illnesses.
But since, pharmacies that time
hardly sold Sulfiathiazole, Que
decided to invest his P100 to buy the
drug and sell these in single doses.
By selling that sulfiathiazole, Que
was able to save money to open up his
first outlet of Mercury Drug in
Bambang, Manila on March 1, 1945.
 In 1948, Que started to buy vehicles to
deliver the medicines to his customers.
 In 1952, Que expanded store hours to 17
hours a day, 7 days a week.
 In 1963, the second branch of Mercury Drug was open
in the Makati Central business district on the invitation
of Ayala Corporation.
 In 1965, Mercury Drug opened its 3rd store in
Quiapo which operates 24 hours a day, 7 days a
week.
 In 1976, Mercury Drug expanded beyond Metro Manila
after it bought Medical Center Drug Corporation, which
produces medical supplies and equipment.
 In 2012, Mercury Drug opened its first drivethru service in Greenhills, San Juan.
Today, the drugstore has over 1,000
branches across the country having
pioneered service like delivery of drugs
and 24/7 operations which is featured
in select stores.
