Q

How should patients used DPI inhalers?

A

Need to breathe in fast and strong to create enough turbulence to lift the particles

these are breath actuated inhalers. Symbicort is an example. You can get a symbicort whistle to test if the patient has the ability to use the inhaler. If they breath in strong enough it will make a noise

Q

Why should Beclometasone CFC-free MDIs (QVAR and CLENIL) have their brand endorsed on prescriptions? What is the combination inhaler also effected by this?

A

Because they are not interchangeable: QVAR has extra fine particles that can reach the lungs faster and quicker therefore its more potent (QVAR is 2 x as potent as Clenil)

FOSTAIR also affected- has extra fine particles (beclometasone and formeterol

Q

Which beta blockers would we be most worried about in asthmatic patients? (5)

A

Non-cardioselective beta blockers, as these may be more likely to constrict airways:

Propranolol Sotolol Labetolol Carvedilol Timolol

The cardioselective ones (atenolol, bisoprolol) are less of a worry but should still be used with caution

Q

How should a spacer be cleaned?

A

Wash it in mild detergent and allow to air dry, wipe mouthpiece free of detergent Do this once a month (more frequently will effect the electrostatic charge)

do not use a cloth to wipe as will create static

Q

What is the standard length of treatment with steroids for an asthma attack? Does this differ in children?

A

Prednisolone oral for 5 days in adult
Prednisolone oral for 3 days in child

IF NBM- IV hydrocortisone every 6 hours until conversion to oral

Can usually abruptly stop the steroid unless the patient has been on oral corticosteroids previously (step 5) for over three weeks

If asthma is uncontrolled in adults (aged 17 and over) on a low dose of ICS and an LTRA as maintenance therapy, offer a long-acting beta2 agonist (LABA) in combination with the ICS, and review LTRA treatment as follows:

discuss with the person whether or not to continue LTRA treatment

take into account the degree of response to LTRA treatment.

This is just the injectable form of theophylline (it consists of theophylline plus ethylenediamine) which is 20 times more soluble (and therefore potent) than theophylline

Theophylline levels are monitored with aminophylline therapy

Q

What does SMART stand for? What does this mean? What inhalers are involved?

A

Symbicort maintenance and reliever therapy Symbicort contains a preventer (budesonide) and a reliever (formeterol)

It is supposed to take away the need for PRN reliever- salbutamol- as you instead use this as the reliever at an increased dose if you get symptoms of breathlessness

Other examples of MART inhalers: Duoresp spiromax (also budesonide and formoterol) Fostair (beclometasone and formoterol)
