Braintree Laboratories is a privately held pharmaceutical company that was founded in 1982 in Braintree, Massachusetts.  Braintree has four prescription product lines in the US market in two therapeutic categories -- gastrointestinal lavages and prescription laxatives.

Braintree Laboratories pioneered the first gastrointestinal lavage in 1984 with the introduction of GoLYTELY^® (PEG-3350 and electrolytes for oral solution). GoLYTELY is indicated for bowel cleansing prior to colonoscopy and barium enema x-ray examination. GoLYTELY was the first to market with this innovative bowel prep technology and was soon adopted as a standard prepping procedure.

The 1990's have seen the introduction of a new generation of gastrointestinal lavages. NuLYTELY^® (PEG-3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution), a reformulation of the original GoLYTELY, provides patients with an improved taste and a 52% less sodium alternative to the other lavages on the market. The NuLYTELY brand has since branched into 4 line extensions which include Cherry Flavored NuLYTELY, Lemon-Lime Flavored NuLYTELY, Orange Flavored NuLYTELY and NuLYTELY with Flavor Packs. 

In 1999, Braintree received approval for MiraLax^™ (polyethylene glycol 3350, NF powder for solution), the first new prescription laxative in 23 years.

The approval and launch of HalfLytely^® and Bisacodyl tablets Bowel Prep Kit (PEG-3350, sodium chloride, sodium bicarbonate and potassium chloride for oral solution and bisacodyl delayed-release tablets) ensued in 2004.  The HalfLytely and Bisacodyl tablets Bowel Prep Kit enables patients to ingest half the volume of solution traditionally required, significantly reducing bowel-prep related discomfort.

Braintree Laboratories is a fully integrated pharmaceutical company maintaining its own manufacturing facilities, warehousing operations, sales and marketing divisions and a pioneering research and development team.
