Asthma — the Pakistan pathway

The national guideline moved to SABA-free treatment. Here is the switching table, the inhaler doses, what to do in an attack — and the beliefs about steroids and nebulisers you will have to work through first.

The number to ask about. Three or more 200-dose canisters a year increases the risk of exacerbation. One canister a month or more increases mortality. This is the single most useful thing on the page for a Pakistani outpatient clinic, because salbutamol inhalers are cheap, sold over the counter, and refilled without anyone counting. Ask how many canisters, not whether she uses one.
Every recommendation here carries a divergence badge. Same as international guideline Pakistan-adapted Local data only National guideline outdated
Most of the clinical content is badged same as international guideline, because this guideline is a faithful adaptation of GINA 2025 and BTS/NICE/SIGN NG245. What is genuinely local is the myths table, and the guideline's own admission — in step 6 — that the strategy it recommends is an extrapolation from evidence gathered elsewhere.
Decision-support only. The published guideline is a scanned document with no text layer, so every table here was transcribed from rendered pages by eye. Verify doses against the original before prescribing. Scope is adults and adolescents 12 and over — the guideline covers 6–11 year olds in a separate chapter that is not reproduced here.

Step 1 · How severe, and how controlled?

Pakistan Chest Society — Clinical Practice Guidelines: Asthma, 2026
Pakistan-adapted The national respiratory society guideline, adapted from GINA 2025 and the joint BTS/NICE/SIGN NG245 guideline by a Pakistani working group.

Severity is a retrospective judgement, not a first-visit label Same as international guideline

MildMinimal symptoms and minimal risk of exacerbations in patients not using inhaled therapies, using reliever therapy alone, or using low-dose inhaled glucocorticoids with reliever therapy.
ModerateGood asthma control on medium-dose inhaled glucocorticoids, or low-to-medium dose inhaled glucocorticoids with additional controller therapy.
SevereAsthma requiring high-dose inhaled glucocorticoids with additional controller agents to maintain good control, or asthma that stays uncontrolled despite those therapies.
The term "mild asthma" should not be used, to avoid giving the impression that mild symptoms equate with low risk.

By these definitions severity can only be assessed after achieving good control and stepping down to the minimum effective controller therapy — or where asthma stays uncontrolled despite maximised treatment. Assess it after several months of controller treatment, when the asthma is stable, not at the first consultation.

Common questions

How many salbutamol inhalers is too many?

Three or more 200-dose canisters a year increases the risk of exacerbation, and one canister a month or more increases mortality. In a country where salbutamol is cheap and sold over the counter, ask how many canisters the patient goes through rather than whether they use one.

What should I switch a salbutamol-only patient to?

Low-dose ICS-formoterol as needed — the anti-inflammatory reliever, or AIR, pathway. A patient on regular low-dose ICS with a SABA reliever switches to low-dose MART; a patient on moderate-dose ICS switches to moderate-dose MART; anyone on a high-dose ICS-containing regimen should be referred to specialist asthma care.

Should I switch every asthma patient off their SABA?

No. The guideline says to identify adults and children 12 and over who can be switched, particularly where asthma is not controlled — but if they are asymptomatic and happy on their current pathway, it is not recommended that they be transferred.

Can I use ICS-formoterol as the reliever with any maintenance inhaler?

No. ICS-formoterol must never be used as the reliever alongside a maintenance ICS-LABA that is not formoterol. And ICS with a non-formoterol LABA, or ICS-SABA, cannot be used as MART at all.

What is the oral steroid dose for an asthma exacerbation?

Adults 40–50 mg/day for 5–7 days. Children 0.5 mg/kg/day, maximum 40 mg/day, for 3–5 days. Tapering is not needed if the course is under two weeks.

When do I give IV magnesium in an asthma attack?

In the emergency department for a severe exacerbation — 2 g intravenously over 20 minutes, alongside SABA, ipratropium bromide, systemic corticosteroids and oxygen. A life-threatening exacerbation goes to ICU.

What oxygen saturation should I target?

93–95% in adults, and 94% or above in children.

Are inhaled steroids addictive or harmful?

No to both, and the guideline lists these among the myths it wants clinicians to correct. Inhaled steroids are not habit forming, and inhalers deliver a very small amount of steroid. The related myth that matters most is that asthma can be managed with a salbutamol inhaler alone — asthma is a disease of inflammation, and salbutamol does not treat inflammation.

How strong is the evidence behind MART in Pakistan?

The guideline says so itself: there is a notable absence of robust clinical data from Pakistan, and the strategy it recommends is an extrapolation from studies in western and other Asian countries. The regional evidence — SMARTASIA, the COSMOS Asian sub-analysis and a Chinese paediatric cohort — is real, but Pakistani trial data is a genuine gap.
