SAS 7 Flashcards
consist of a sheet of steel plate that has been electroplated on both sides with tin
Tinplate containers
is used to manufacture extruded (seamless) aerosol containers
aluminum containers
aluminum can be corroded by?
pure water and pure ethanol
is used to attach the valve proper to the container
mounting cup
allows for the escape of vaporized propellant along with the liquid product.
vapour tap
serves to hold the gasket in place
Spring
allow for easy opening and closing of the valve
actuators
these actuators are capable of “mechanically” breaking a stream into fine particles by causing the stream to swirl through various channels built into the actuator.
Spray actuators
These actuators consist of relatively large orifices ranging from approximately 0.070 inch to 0.125 or greater
foam actuators
the dispensing of such semisolid products as ointments generally requires these actuators
solid-stream actuators
these system are those that use repetitive, intermittent dosing of a drug from one or more immediate release units incorporated into a single dosage form.
delayed release
designed to achieve a prolonged therapeutic effect by continuously releasing medication over an extended period of time after administration of single-dose of drug.
sustained release
these system include any drug delivery that achieves slow release of drug over an extended period of time
controlled release
these system releases the drug slower than normal manner at a predetermined rate and necessarily reduce the dosage frequency by two folds.
extended release
specific to diseased organ or tissue
site-specific targeting
