1Limiting factors that restrict drugs to certain dosage forms:
• [blank_start]Solubility[blank_end]
• [blank_start]Stability[blank_end]
• [blank_start]Absorption[blank_end]
• [blank_start]First pass[blank_end] effect
• [blank_start]Dose[blank_end]- ASolubility
- BStability
- CAbsorption
- DFirst pass
- EDose
2[blank_start]Sublingual[blank_end], [blank_start]buccal[blank_end], and [blank_start]IV[blank_end] dosage forms have a quick effect and reach maximum plasma concentration a lot faster after administration.
- ASublingual
- Bbuccal
- CIV
3[blank_start]Oral[blank_end] and [blank_start]ointment[blank_end] dosage forms reach its maximum plasma concentration a long time after administration.
- AOral
- Bointment
4Sublingual route dosage forms:
- Tablets
- [blank_start]Troches[blank_end]
- [blank_start]Lozenges[blank_end]- ATroches
- BLozenges
5Disadvantages of the oral route:
- [blank_start]First pass[blank_end] effect
- Unpredictable absorption due to factors such as [blank_start]diet[blank_end] and [blank_start]age[blank_end] that affect bioavailability- AFirst pass
- Bdiet
- Cage
6If a drug is administered in a soluble form or it dissolves rapidly, [blank_start]membrane transport[blank_end] will become rate limiting step
- Amembrane transport
7Dissolution rate from highest to lowest are as following:
[blank_start]Liquids[blank_end] and [blank_start]solutions[blank_end] > [blank_start]Suspensions[blank_end] > [blank_start]Capsules[blank_end] > [blank_start]Tablets[blank_end]- ALiquids
- Bsolutions
- CSuspensions
- DCapsules
- ETablets
8[blank_start]Intrinsic dissolution[blank_end]: Dissolution rate that is specific to each drug
- This is characterized by Noyes-Whitney equation- AIntrinsic dissolution
9Factors affecting intrinsic dissolution:
Increase in [blank_start]temperature[blank_end] = Increase in rate of dissolution (affects Cs)
Decrease in [blank_start]viscosity[blank_end] = Increase in rate of dissolution (affects D)
[blank_start]Agitation[blank_end] (mixing/taking with food) = Increase in rate of dissolution (affects h)
Change in [blank_start]pH[blank_end] = Affects Cs
Decrease in [blank_start]size[blank_end] = Increase in rate of dissolution (affects S)- Atemperature
- Bviscosity
- CAgitation
- DpH
- Esize
10Factors affecting solubility:
- [blank_start]Polymorphism[blank_end] (diamonds vs graphite)
- [blank_start]Hydrated[blank_end] vs [blank_start]anhydrous[blank_end] form (thirsty)
- [blank_start]Salt[blank_end] form (depends on drug)- APolymorphism
- BHydrated
- Canhydrous
- DSalt
11Major mechanism of drug absorption through the GI tract is [blank_start]diffusion[blank_end]
- generally follows first order kinetics- Adiffusion
12[blank_start]Hydrogen binding[blank_end] groups of an unionized form of a drug do not have good absorption via diffusion because they usually get trapped within the cell membrane.
- AHydrogen binding
13Active transport does not follow first order kinetics because pumps can be [blank_start]saturated[blank_end]
- Asaturated
14[blank_start]Colloidal[blank_end] range particles can be absorbed via endocytosis/exocytosis. This does not play a major role because the process is quite slow.
- AColloidal
15Fatty foods will increase [blank_start]residence time[blank_end] of a drug in the stomach
Fat > Proteins > Carbohydrates- Aresidence time
16F systemic = f [blank_start]released[blank_end] × f [blank_start]absorbed[blank_end] × f [blank_start]hepatic[blank_end]
- Areleased
- Babsorbed
- Chepatic
17For aerosol dosage forms for inhalation into the lungs:
If you want a systemic effect, the drug size should be [blank_start]0.5[blank_end] - [blank_start]1[blank_end] mcm
If you want a local effect, the drug size should be [blank_start]1[blank_end] - [blank_start]10[blank_end] mcm- A0.5
- B1
- C1
- D10
