- Topical dosage forms
A homogeneous mixture that is prepared by dissolving a solid or liquid or gas in another liquid. It represents a group of preparations in which the molecules of the solute or dissolved substances are dispersed among those of the solvent.
Solution
Water is used as the vehicle or the solvent.
Aqueous solutions.
Aqueous solutions
- Water
- Aromatic water
- Aqueous acids
- Diluted Acids
- Solution
is used mainly as a vehicle and as a solvent for the desired flavoring or medicinal ingredients.
Water
also known as medicated water; clear saturated aqueous solutions of volatile oils or other aromatic or volatile substances. Used mainly as flavored or perfumed vehicles.
Aromatic water
official inorganic acids and certain acids although of minor significance as therapeutic agents but of great importance in chemical and pharmaceutical manufacturing. Available commercially in the form of concentrated aqueous solutions and expressed in % by weight.
Aqueous acids
aqueous solutions of acids of suitable strength usually 10%w/v except diluted Hac which is 6% w/v. They are used for internal administration or for the manufacture of other preparations.
Diluted Acids
is a liquid preparation that contains one or more soluble chemical substances dissolved in water. Solutions are used for the specific therapeutic effect of the solute either internally or externally.
Solution
aqueous solutions directed against a part or into a cavity of the body as a cleansing or antiseptic agent.
Douches
They are rectal injections employed to evacuate the bowel; retention enemas to influence the general system by absorption, or to effect locally the seat of the disease.
Enemas
aqueous solutions used for treating pharynx or the nasopharynx by forcing air.
Gargles
aqueous solutions which re most often used for their deodorant, refreshing or antiseptic effect
Mouthwashes
are prepared from fresh ripe fruits, aqueous in character and used in making syrups employed as vehicles.
Juices
are usually aqueous solutions designed to be administered to the nasal passages in drops or spray form.
Nasal solutions
aq.preparations dispensed in a container which permits the administration of drops to the ear.
Otic solutions
concentrated solutions of sugar such as sucrose in water or other aq. liquid, used either as flavored syrup or medicated syrup.
Syrups
thick liquid preparations somewhat allied to syrup and used as a base in place of syrup.
Honey
thick, viscid, adhesive liquids produced by dispersing gum in water or by extracting with water the mucilaginous principles from vegetable substances. Used to aid in suspending insoluble substances in liquids; their colloidal character and viscosity help them prevent immediate sedimentation.
Mucilages
are class of gels in which the structural coherent matrix contains a high proportion of liquid, usually water. Used as lubricants for surgical gloves, catheters and rectal thermometers. Activate Windows Go to Settings to activate Widok
Jellies
a liquid preparation containing 1 pyroxillin in a mixture of ethyl ether and ethanol. Applied to the skin by means of a soft brush or other suitable applicator & when the ether and alcohol evaporated, they leave a film of pyroxillin on the surface.
Colloidion
are clear, pleasantly flavored sweetened hydroalcoholic liquids intended for oral use, as flavors and vehicles.
Elixirs
are solutions or mixtures of medicinal substances in not less than 50% by weight of glycerin.
Glycerin or glycerites
drugs or solutions of drugs administered by the nasal or oral respiratory route for local or systemic effect.
Inhalations and inhalants
used for the administration of inhalations. Inhalants - are special class of inhalation where drugs are delivered via high power pressure carried by air current into the nasal passage, the container is called the inhaler.
Nebulizers
solutions or mixtures of various substances in oil, alcoholic solutions of soap or emulsions, intended for external application, rubbed on affected areas.
Liniments
are fish liver oils diluted with edible vegetable oil or solutions of volatile substances of the indicated vitamins or vit.concentrates (usually vit A & D) on fish liver oil.
Oleovitamins
are popularly known as essences, are - alcoholic or hydroalcoholic solutions of volatile substances. A few are used medicinally by inhalation, while a large number as flavoring agents.
Spirits
preparations used for the temporary relief of toothache
Toothache drops
Are a two phase system prepared by combining two immiscible liquids, one of which is uniformly dispersed through the other; they consist of globules that have diameters equal to or greater than those of the largest colloidal particles.
Emulsions
Are a two-phase system consisting of finely divided solid dispersed in a solid, liquid, or gas. Suspending agent is added to ensure appropriate dispersion of the solid in the vehicle.
Suspensions
A homogeneous non-crystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second
substance.
COLLOID
A fine dispersion of minute droplets of one liquid in another in which it is not soluble or miscible.
Has two liquid components that are immiscible with each other.
