Vehicle is a carrying agent which is used in formulating a variety of liquids for oral and parenteral administration Generally, oral liquids are aqueous (e.g., syrups)
Tablet or capsule opaquant is used to render a coating opaque. It may be used alone or with a colorant.
Examples
• Titanium dioxide
Tablet polishing agent is used to impart an attractive sheen to coated tablets.
Examples
• Carnauba wax
• White wax
Tonicity agent is used to render solution similar in osmotic-dextrose characteristics to physiologic fluids, for example, in ophthalmic, parenteral, and irrigation fluids.
Tablet disintegrant are used in solid forms to promote disruption of the mass into smaller particles more readily dispersed or dissolved.
Examples
Alginic acid
Tablet glidants are used in tablet and capsule formulations to improve flow properties of the powder mixture.
Examples
• Colloidal silica
• Cornstarch
• Talc
Tablet coating agents are used to coat a tablet to protect against decomposition by atmospheric oxygen or humidity, to provide a desired release pattern, to mask taste or odor, or for aesthetic purposes. Coating may be sugar, film, or thick covering around a tablet.
Tablet direct compression excipient is used in direct compression tablet formulations.
Examples
Dibasic calcium phosphate (e.g., Ditab)
Tablet and capsule diluents are used as inert filler to create desired bulk, flow properties, and compression characteristics of tablets and capsules.
Examples
Dibasic calcium phosphate
Kaolin
Tablet binders are substances used to cause adhesion of powder particles in tablet granulations.
Examples
Acacia
Tablet antiadherents are used to prevent tablet ingredients from sticking to punches and dies during production.
Sweetening agent is used to impart sweetness to a preparation.
Examples
Aspartame
Dextrose
Suppository base is used as vehicle for suppositories.
Examples
Cocoa butter
Polyethylene glycols (mixtures)
PEG 3350
Surfactants (surface active agent) are substances that absorb to surfaces or interfaces to reduce surface or interfacial tension. May be used as wetting agents, detergents, or emulsifying agents.
Examples
Benzalkonium
