Suppositories & Pessaries

Increased efficiency and local treatment

Suppositories and pessaries are an ideal method of administration for a drug when the oral route is not possible due to nausea or vomiting. This is one of the best ways to avoid the first-path effect, which lowers the efficacy of a drug product. Unither has many years of experience in the manufacture of suppositories and, in collaboration with our Innovation & Development site in Bordeaux, we can oversee the complete development of a suppository, from its development to its manufacture. Suppositories and pessaries are usually packaged in blister packs.
