Pain relief starts soon after taking the first dose and a full analgesic effect should normally be obtained within a week, whereas an anti-inflammatory effect may not be achieved (or may not be clinically assessable) for up to 3 weeks.

Q

MoA of Methotrexate

A

inhibition of enzymes involved in purine metabolism

13
Q

MoA of Sulphasalazine

A

Suppression of IL-1 & TNF-alpha, induce apoptosis of inflammatory cells and increase chemotactic factors

14
Q

MoA of Leflunomide

A

Pyrimidine synthesis inhibitor

15
Q

MoA of Hydroxychloroquine

A

induces apoptosis of inflammatory cells and decrease chemotaxis

16
Q

Side effects of Methotrexate

A
  • hepatitis, cirrhosis, pneumonitis, rash, ulcers, reduction of white blood cells,
  • it’s teratogenic
17
Q

What should be done whilst on Methotrexate?

A

Subcutaneous injection

20
Q

How can Anti-TNFs become more effective?

A

by being taken alongside DMARDS

21
Q

What are side effects of Anti-TNFs?

A

Risk of infection, especially TB

22
Q

MoA of Anti-TNFs

A

They suppress the physiologic response to tumour necrosis factor (TNF), which is part of the inflammatory response.

23
Q

Name some Biologics

A
Rituximab
Tocilizumab
Abatacept
Ustekinumab
Secukinumab
24
Q

A

monoclonal antibody against B lymphocytes

25
Q

A

inhibits IL6

26
Q

composed of CTLA-4 Ig- that blocks activation of T lymphocytes

27
Q

MoA of Ustekinumab

A

inhibits IL12 and IL23

28
Q

A

inhibits IL17

29
Q

Name some urate-lowering drugs

A

Allopurinol

Febuxostat

30
Q

When would you use Febuxostat?

A

For those who cannot tolerate allopurinol

31
Q

MoA of Allopurinol and Febuxostat

A

xanthine oxidase inhibitors

32
Q

Side effects of Allopurinol

A

rash in elderly / renal patients

interacts with azathioprine

33
Q

MoA of Azathioprine

A

Azathioprine inhibits purine synthesis. Purines are needed to produce DNA and RNA. By inhibiting purine synthesis, less DNA and RNA are produced for the synthesis of white blood cells, thus causing immunosuppression.

34
Q

What kind of drug is azathioprine?

A

Immunosuppressant

35
Q

What should you always prescribe with Allopurinol?

A

NSAIDS- as Gout can be exacerbated due to rapid reduction in uric acid level

36
Q

Name some Uricosuric drugs

A

Probenecid
Sulphinpyrazone
Benzbromarone

37
Q

MoA of Uricosuric drugs

A

they increase the excretion of uric acid in the urine by acting on the proximal tubule

38
Q

When are uricosuric drugs contraindicated?

A

Renal patients

39
Q

MoA of Colchicine

A

interrupts the cycle of monosodium urate crystal deposition in joint tissues and the resultant inflammatory response that initiates and sustains an acute attack

40
Q

Side effects of colchicine

A

GI upset

Dont’s take with macrolides: erythromycin/ clarithromycin
