What is sotalol?
a non-Cardioselective BB, with Class III antiarrhythmic activity.
Which is more effective in the treatment of sustained ventricular tachycardia:
lidocaine or sotalol
Sotalol
How do Beta Blockers work as anti-arrythmics?
By attenuating the effects of the sympathetic system on automaticity and conductivity within the heart
What is Exocrine Pancreatic Insufficiency?
reduced secretion of pancreatoc enzymes into the duodenum.
Manifests as:
- maldigestion and malnutrition
(low circulating micronutrients, fat-soluble vitamins and lipoprotiens)
- Diarrhoea, abdominal cramps etc
Why do we not abruptly stop antiepilects?
Abrupt withdrawal can cause severe rebound seizures
particularly with barbiturates
barbiturate withdrawal may take several months

What is Digoxin?
A cardiac glycoside
Digoxin Indications
Atrial Fibrillation
Tachycardia
Heart Failure
How does Digoxin work?
as a positive inotrope
–> Increases the force of myocardial contraction and reduces conductivity within the AV node
Side Effects of:
Digoxin
Nausea Vomiting Diarrhoea Dizziness Blurred Vision
Desired Serum Concentration of:
Lithium
0.4 - 1 mmol/L
> 1.5 mmol/L may be toxic and fatal
Recommended for the treatment atrial flutter without structural heart defects or after heart surgery
D.C. shock or Cardiac pacing.
Drug treatment not necessary
Main counselling point to a 28 year old woman prescribed Basiliximab
woman of child bearing potential should use adequate contraception to prevent pregnancy, and continue to use it for an additional 4 months after the last dose of Basiliximub.
They should also not breast feed for 4 months after the last dose.
Lithium counselling points
Maintain adequate fluid intake
Avoid dietary changes which reduce or increase sodium intake.
Which Beta Blockers are water soluble?
celiprolol
Atenolol
Nadolol
Sotalol
less likely to enter the blood brain barrier, therefore less likely to cause sleep disturbances and nightmares
How are water soluble Beta blockers excreted?
Via the kidneys
dose reduction is often needed in renal impairment
Names some bisphosphonates
Alendranate | Risadronate
Bisphosphonates indication
Secondary prevention of osteoparatic fractures in susceptible post-menopausal women.
Raloxifene indication
For those who can not take bisphosphonates or who have suffered a fragility fracture despite treatment for a year and have a decline in bone marrow density (below pre-treatment level)
What is Teriparatide?
Parathyroid hormone fragment, used in osteoporosis.
for woman >65, who can’t take bisphosphonates (or for who bisphosphonates have failed) and have:
- extremely low bone marrow density
or
- low bone marrow density, suffered more than 2 fractures, BMI < 19 and premature menopause
Prevalence of G6PD deficiency?
Africans
Asians
South Europeans
Define MCV
and state normal range
The average volume of a red blood cell.
Normal: 80 - 100fl
Possible causes of a high MCV
Methotrexate toxicity

Normal white blood cell count
4 - 11 x10^9 /f
Causes of abnormal white blood cell count
High WBC could indicate::
- infection
- person is on steriods
Low WBC could indicate:
- Methotrexate harming bone marrow
Normal Platelet Count
150 - 400 x10^9/L
Possible cause of abnormal platelet count
Low platelet count could indicate:
- Methotrexate harming bone marrow
Normal Lymphocyte Count
1.5 - 4.0 x10^9/L

Define high Serum Urea, and what it could indicate
> 10 mmol/L
Could indicate renal failure, dehydration, high dietary protein intake, hypercatabolic state or haemorrhage.
Note: further tests are required to give more accurate assessments
If renally impaired, all drugs with significant renal excretion needs to be assessed
Normal Urea range
2.5 - 8 mmol/L
varies with age
Normal Creatinine range
60 - 125 micromol/L
varies with age
