- sodium chloride, antihistamines,corticosteroids,ipratropium and xylometazoline
- not to be used for prolonged periods of time ( 7 days)
- can be used in pregnancy - low systemic absorption
Nasal polyps - review by ent specialist - use nasal corticosteroid
Nasal staphylococci-
Naseptin (contains peanuts) or mupirocin

42
Glaucoma
Most common form - open angle glaucoma
- due to restricted drainage of the aqueous humour through trabecular mesh work leading to ocular hypertension
Treated with topical prostaglandin analogues (latanoprost,tafluprost, tavoprost, bimaprost)
- if initial prostaglandin analogues hasn’t worked, try different one
- if doesn’t work, topical beta blocker : betoxolol,levobutunolol or time lol
If that doesn’t work carbonic anhydride inhibitors - brinzolamide or dorzolamide
Brimonidine and piclocarpine can also be used
43
Prostaglandin Analogues
Latanoprost. Tafluprost, tavoprost or bimaprost
Dry eyes
Ocular discomfort
Change to eye colour
Hyperpigmentation of periocular skin
Darkening, thickening and lengthening of eye lashes
44

Symptoms - nodules,swelling, tenderness, malaise, fatigue, fever and weight loss
Non drug therapy - physiotherapist, exercise, relaxation and stress management
46
DMaRDs - Drug therapy RA
FISRT LINE - Methotrexate,leflunomide or sulfasalazine(hydroxychloroquine in mild)
SECOND LINE - MoAbs - adalimumab,infliximab,toclizumab,baricitinib
- Bridge with corticosteroids when rapid suppression is needed
NSAIDs can be used in pain relief - withdraw when response to DMARDS is enough
47
Methotrexate
- Taken ONCE weekly
- prescription and label should clearly show the dose and frequency
- methotrexate is commonly co- prescribed with folic acid, not to be taken on the same day as each other
- patient should be advised to immediately report any signs of blood disorder, liver toxicity and respiratory effects
48
Methotrexate side effects
Blood disorders: Sore throat, bruising and mouth ulcers
Liver tocity - nausea,vomiting, abdominal discomfort, dark urine, jaundice, itchy skin
Pulmonary toxicity - SOB and coughing
Gastrointestinal toxicity - stomatitis and diarrhoea
49
Methotrexate toxicity antidote
FOLINIC ACID
Calcium folinate
50
Methotrexate monitoring and screening
Full blood count, renal function test, liver function test:
- every 1-2 weeks until stable
- every 2-3 months thereafter
Screen out pregnancy prior to treatment:
- antifolate - harmful to foetus growth
- use effective contraception during treatment and for at least 6 months after for both men and women
51
MTX interactions
- nephrotoxic drugs: mtx reduced renal function
- NSAID = nooooo
Antifolates: trimethoprim and phenytoin
- hepatotoxic drugs: Rfiampicin, antfungals etc
Omeprazole and esomeprazole:
- reduced clearance = increases toxicity
52
Hyperuricaemia and gout
Raised Uric acid concentration in the blood - hyperurucaemia and the deposition of irate crystals in the joints and other tissues
Can be caused by -
- diet (high salt intake)
-medication
-bendroflumethazide
- chemotherapy drugs
53
Treatment of acute gout
Started treatment as soon as possible
- treat with colchicine or high doses of an NSAID and PPI (Excluding aspirin)
- colchicine 500 mcg 2-4 times max 3 days - do not repeat course within 3 days
NSAIDs induced fluid retention (interaction with diuretic)
Alternative -
- short course of oral corticosteroid
- IM injection of corticosteroid or canakinumab
54
Treatment of chronic gout
- offered in frequent acute attacks of gout (2 or more in a year)
- uric acid may be reduced with xanthine - oxidase inhibitors
First line- allopurinol
Second line - febuxostat - caution with febuxostat patients with history of cardiovascular disease
If acute attack happened during treatment - continue chronic treatment as well as treating the attack separately
55
Allopurinol
When starting,flare- prophylaxis with colchicine/ NSAID is recommended
Common side effect- rash - discontinue if mild but restart carefully but discontinue immediately if recurrence
Interaction - allopurinol +azithropine/meracartopurine
Reduce dose of aza/merc
56
Nocturnal Leg cramps
Quinine sulfate - may reduce the frequency of nocturnal leg cramps

Trial for 4 weeks - if there is benefit - continue
Stop treatment every 3 months and assess need for further treatment

GI = Piroxicam, ketoprofen,ketorolac
CVD - COX-2 Selective inhibitors, ibuprofen 2.4 g, diclofenac
59
Medium risk
GI- Idometacin,diclofenac,naproxen
60
LOW
GI-Ibuprofen
CVD - Naproxen, ibuprofen 1.2g
61
Lowest
GI = cox 2 selective inhibitors
62
Cox -2 - selective inhibitors
Celecoxib, etoricoxib
63
Pain and inflammation - NSAIDS
- NSAID + low dose aspirin = increase GI bleed risk (use only if needed)
- NSAIDS and alcohol - increase GI bleed risk
- Use stomach protection PPI
- Hypersensitivity reactions - cross sensitivity with aspirin too
- avoid in renal impairment - risk of fluid retention and further impairment
- avoid in pregnancy - caution in breastfeeding
64
Interactions - NSAIDS
MTX/LITHIUM- Reduces clearance
Ciprofloxacin = increases risk of seizure
Blood thinners = increases risk of bleeding

CAUTION WITH NSAID FROM 20TH WEEK
