Questions in this quiz (6)
1Select all the advantages of liquid dosage forms.
- AMore accurate dosing
- BEasier to swallow than tablets
- CLeakage from container
- DBulkiness of packaging
- EFaster drug absorption
- FPoorer stability than tablets
2By dissolving a drug in a solvent we create a [blank_start]solution[blank_end].
By suspending or dispersing the drug in a solvent we create a [blank_start]suspension[blank_end].
By incorporating the drug into water or an oil phase(s) we create an [blank_start]emulsion[blank_end].- Asolution
- Bsuspension
- Cemulsion
3Solubility is the [blank_start]maximum concentration[blank_end] or amount of a substance ([blank_start]solute[blank_end]) that may be [blank_start]completely[blank_end] dissolved in a given [blank_start]amount[blank_end] of solvent at a given temperature and pressure.
- Amaximum concentration
- Bsolute
- Ccompletely
- Damount
4Partial miscibility results in two layers each containing some of the other liquid in a dissolved state.
- ATrue
- BFalse
5[blank_start]Dissolution[blank_end]: process by which a substance (e.g. a drug or API or solute) goes into solution.
[blank_start]Solvation[blank_end]: attraction and association of molecules of a solvent with molecules or ions of a solute.
[blank_start]Hydration[blank_end]: when water is used as the solvent.- ADissolution
- BSolvation
- CHydration
6The dissolution process must begin when [blank_start]solute-solute[blank_end] bonds are broken. Then, [blank_start]solvent-solvent[blank_end] bonds will break, and finally [blank_start]solute-solvent[blank_end] bonds will form.
- Asolute-solute
- Bsolvent-solvent
- Csolute-solvent
