is a viscous
syrupy liquid meant to be licked slowly for soothing
the throat. It generally has menthol to impart
cooling sensation, and an antitussive.
4.Drops
These are relatively more concentrated solutions of
medicaments meant for oral ingestion or external
application to eye, nose or ear canal. Oral drops are
the preferred dosage form for infants and young
children. Eye/nasal drops should be isotonic. Eye
drops must also be sterilized. Drops are supplied in
vials with a nozzle or alongwith a dropper.
5.Lotions
These are solutions, suspensions or emulsions
meant for external application to the skin without
rubbing. They generally have soothing, protective
or emollient property.
Liniments
are similar
preparations which generally contain
counterirritants and are to be rubbed on the skin to
relieve pain and cause rubefaction.
6.Injections
These are sterile solutions or suspensions in
aqueous or oily medium for subcutaneous or
intramuscular administration, while only aqueous
solutions (not suspensions) are suitable for
intravenous (i.v.) injection, because particles in
suspension and oils injected i.v. can cause
embolism. Injections are supplied in sealed glass
ampoules
