What is the difference between glident and lubricant?
Lubricants are added to tablet formulations primarily to reduce
friction between the die wall and granules as the tablet is formed
and ejected (Sprowl, 1974; Lachman et al., 1970). The other main
activities attributed to a lubricant are: (a) prevention of
sticking of granules to the tooling-anti-adherent; and (b)
improvement of granule flow properties-glidant (Lachman et al.,
1970). A given lubricant may provide one or more of these actions
to varying degrees but no one material is highly efficient in all
categories (Sperandeo and De Machi, 1976; Strickland, 1959; Sprowl,
1974).
