A suspension includes the active component(s) That could be dispersed in the propellant technique Along with the aid of suitable excipients which include wetting brokers and/or reliable carriers for example talc or colloidal silicas.
DELAYED-RELEASE TABLETS Where the drug may very well be wrecked or inactivated from the gastric juice or exactly where it may irritate the gastric mucosa, using “enteric” coatings is indicated.
Basic COATED TABLETS Classically, tablets are coated with sugar utilized from aqueous suspensions containing insoluble powders for instance starch, calcium carbonate, talc, or titanium dioxide, suspended by means of acacia or gelatin.
