Antigalactic refers to a substance that prevents or decreases the secretion of milk.
Other words that contain gala (or its combining forms gal-, galact-, or galacto-) include:
galactose – a simple sugar derived from the milk sugar lactose. (The suffix -ose means a sugar.)
galactase – an enzyme that is used by the body to help digest galactose. (The suffix -ase means an enzyme. Compare with lactase, an enzyme used to break down lactose, or milk sugar, into its two component parts—the simple sugars galactose and dextrose. Lac-, by the way, is the Latin combining form for “milk.”)
agalactia [a, not + “] absence of milk secretion after childbirth
