Q

Define enteric coating

A

The coating is designed to hold together in acid conditions and break down in non-acid conditions and therefore release the drug into the intestines.

17
Q

TRUE OR FALSE?

Modified-release: Slow the release of the drug so that the medicine does not have to be taken too often and therefore makes it easier to remember to take.

A

TRUE

18
Q

One advantage of taking modified-release tablets

A

the concentration of the drug in the body goes up slowly, is less likely to go very high and therefore reduces the chance of side effects.

19
Q

Examples of modified-release tablets

A 
Diffundox MR
Elantan LA
Dilzem XL 
Calcicard CR
Dilcardia S
20
Q

What abbreviations would you see on tablets or capsules with modified release

A 
MR
LA
XL 
CR
SR
21
Q

What are film coated tablets?

A

very thin layers of a safe ingredient are placed around the tablet to again protect the tongue from the flavour of the contents and protect the contents from moisture and light.

22
Q

How are film-coated tablets broken down in the body?

A

The film will break down with agitation and significant amounts of moisture (saliva or stomach acid) and therefore does not significantly affect the way in which the drug is absorbed into the body.

23
Q

TRUE OR FALSE?

Each tablet or capsule holds a relatively small dose of the drug, crushing the formulation significantly decrease the maximum serum levels and reduces the minimum serum levels. Consequently, crushing cannot cause side effects and periods where the drug is not working at all.

A

FALSE

Correct statement:
Each tablet or capsule holds a relatively large dose of the drug, crushing the formulation significantly increases the maximum serum levels and reduces the minimum serum levels. Consequently, crushing can cause side effects and periods where the drug is not working at all.

24
Q

Crushing tablets with small therapeutic effects or those with peak effects increases/decreases the chances of side effects and times when the drug is less likely to work.

A

increases

25
Q

Capsules which you would need to open, does the drug need to be consumed WITH or WITHOUT food?

A

With

26
Q

What types of food would you need to have with opened and sprinkled capsules?

A

Soft food

27
Q

Capsules that need to be sprinkled and consumed with foods, do you have to eat in one go or can you save it and eat later?

A

Eat in one go

28
Q

Could liquid medications be a solution for swallowing difficulties?

A

Yes

29
Q

What should you consider when switching from a solid to liquid dose form?

A

Dose equivalence. Calculations may be required due to differing bioavailability.

30
Q

Concerning liquid medications:
The consistency of liquid formulation is/isn’t an important
consideration.

A

Is

31
Q

If a liquid medication is too runny what does this cause?

A

Aspiration

Aspiration is when something enters the airway or lungs by accident. It may be food, liquid, or some other material

32
Q

If a liquid medication is too viscous would this be suitable for the patient?

A

No

33
Q

For patients with difficulty swallowing what could you do for the patient?

A

SALT referral

(Speech and Language Therapy Service provide evidence-based services that anticipate and respond to the needs of individuals who experience speech, language, communication or swallowing difficulties)

34
Q

What does the abbreviation ‘SALT’ referral mean?

A

Speech and Language Therapy

35
Q

What are pharmaceutical specials medicines?

A

Specials, like all unlicensed medicines, should only be
prescribed when there is no available licensed medicine
which fully meets the patient’s special clinical needs.

36
Q

When should ‘Specials’ be prescribed?

A

when it is judged by the prescriber and agreed with the patient or carer that, on the basis of available information, the use of a Special is the most appropriate option for the patient.

37
Q

6g

• 6g = 2.4g or 100mmol of sodium

41
Q

What is the daily salt target for children 11+ in the UK?

A

6g

• 6g = 2.4g or 100mmol of sodium

42
Q

What can’t go in the Monitored Dosage System (MDS)?

A
  • Liquids
  • Creams
  • Inhalers
  • Patches
  • Effervescent/dispersible products
  • S/L, buccal etc
  • Hygroscopic products
  • Where packaging is part of the licence eg Epilim
