Soft Capsules Flashcards
what does a soft capsule consist of
liquid or semisolid matrix hermetically sealed inside a one piece flexible gelatin shell
what are softcapsules sometimes referred to as
softgel
what does a capsule shell comprise of
gelatin plasticiser water preservatives dyes
give 2 examples of a plasticiser
glycerol or propylene glycol
describe a softgel composition
geletin 35-40 plasticizer 15 -25 water ~40 dye opacifier if needed flavourings
what are 4 applications of softgels
oral dosage form
chewable softgel
suppositories
topical products
describe the effect of the softgel composition form on bioavailability
quicker absorption due to liquid form there for better bioavailability
advantages of softgel composition
improved drug bioavailability
formed filled and sealed in one go
easy to swallow -> better patient compliance
dose uniformity and precision
safer manufacturing due to lack of air borne powders
drugs are protected against oxidation
disadvantages of softgel composition
manufacture is complex and time consuming
specialized equipment needed
high quality geletin needed
give 5 examples of softgel fill matrices
lipophilic liquids
hydrophilic liquids
self emulsifying oils
micro emulsion systems
drug suspensions
what are the requirements for formulation of soft capsule products
a stable physical form of drug
a fill vehicle that minimizes transfer of water
excipient free from interactions and impurities
inert environment during manufacturing
moderate drying conditions
