Tranexamic acid formulated in an oral dosage form with at least one agent that decreases tranexamic acid release in the stomach. Such formulations minimize nausea, vomiting, and other adverse gastric effects that may accompany tranexamic acid therapy, for example, to treat heavy menstrual bleeding. One embodiment is an extended release formulation with waxes, polymers, etc. that prevent a bolus release of tranexamic acid in the stomach. An alternative embodiment is a delayed release formulation with polymers that prevent release of tranexamic acid in the acid environment of the stomach and delay its release until the formulation reaches the less acid environment of the intestines. Such formulations enhance patient compliance with therapy because adverse effects of tranexamic acid therapy are reduced.

A method for processing a fruit, such as a cranberry, includes cutting open a fruit and partially removing a highly concentrated juice fraction from the fruit when pressed while maintained within a sub-freezing temperature range. The skin of the frozen fruit is penetrated by being sliced or punctured facilitating juice extraction and subsequently infusion, such as by vacuum. Before extraction, the sliced fruit is uniformly tempered to a temperature below 32° F., more specifically to between 26° F. and 32° F. To extract juice, the fruit is pressed, removing from about 40% to 65% by weight of the liquid, yielding a concentrated fruit juice, with significantly enhanced brix, acid, and color, and a partially dehydrated fruit piece, with significantly reduced brix, acid, and color, and still within the given sub-freezing temperature range. The fruit piece may then be infused, such as under vacuum while being rotated, with a variety of ingredients.
