But the company said worldwide pharmaceutical sales were up in the quarter and listed among the "important contributors" Prozac, the ulcer drug Axid; the antibiotic Ceclor and the generically engineered insulin Humulin. Lilly said sales of medical devices and animal health produces also increased. Eli Lilly stock rose $1.375 a share yesterday on the New York Stock Exchange, to $81.625. Upjohn Upjohn said quarterly earnings were $133.3 million, or 73 cents a share, compared with $114.3 million, or 61 cents, a year ago. Sales rose 10.5 percent to $799.4 million, from $723.4 million a year earlier. Upjohn said it was helped by a decline in its estimated annual tax rate to 27 percent, compared with 32.5 percent in 1990, because the company increased the portion of earnings from its factories that qualify for tax breaks in Puerto Rico. Upjohn said pretax earnings from continuing operations rose 5 percent, pulled down by new requirements to provide rebates on drugs to state Medicaid programs for the poor.
