Lactic Acidosis with Hypokalaemia

Why exactly does this occur. I understand salbutamol increases K+ entry into cells, which therefore increases H+ entry into the blood (K+/H+ exchange) but I thought this would be a metabolic acidosis - why then does lactate build up?

A 77 year old man with asthma and renal impairment

A 77 year old man presented after a collapse at home with a three week history of dyspnoea, malaise, and myalgia. He reported a 10 year history of hypertension, and that he had undergone a nasal polypectomy seven years earlier and had recently been diagnosed as having asthma. Prescribed drugs included candesartan 4 mg daily, enalapril 20 mg daily, beclometasone dipropionate 200 µg twice daily, and salbutamol as needed. He had not recently changed his drugs or used non-steroidal anti-inflammatory agents or herbal remedies. On examination his blood pressure was 156/88 mm Hg; temperature was 36.8°C; and he had generalised polyphonic wheeze, raised jugular venous pressure (5 cm above the sternal angle), and mild bilateral ankle oedema.

Self management for a man with asthma

A 35 year old man with a history of asthma attended the practice asthma clinic a few weeks after an acute exacerbation. He was a non-smoker who had asthma as a child but “grew out of” the more troublesome symptoms in his teens. He regards his asthma as well controlled, although his computer record suggested that he has had six short acting bronchodilator inhalers in the past year. He is more troubled by hay fever, which he manages with antihistamines that he buys from the pharmacy. He has a sedentary lifestyle so avoids exercise induced symptoms. He has a repeat prescription for an inhaled steroid (which he takes “when he needs it”) and carries a salbutamol inhaler with him in case he experiences any chest tightness. Despite annual invitations to the asthma clinic he last attended six years ago.
