Application

Salmeterol xinafoate was used as conjugate with human serum albumin to study the immune responses in rabbits.7

Biochem/physiol Actions

Salmeterol xinafoate is a β2 adrenoceptor agonist with longer lasting bronchodilation and anti-inflammatory effects. It relaxes the airway smooth muscles, stabilizes mast cells and regulates the release of histamine. Salmetrol is particularly effective in treatment of mild asthma, chronic obstructive pulmonary disorder.5,6

Indacaterol is a once-daily, long-acting β(2)-agonist bronchodilator that improves dyspnoea and health status in patients with moderate-to-severe COPD. While its bronchodilator effects have been shown to be maintained in different patient subgroups, effects on clinical outcomes in certain subgroups are

Haptens are low molecular weight compounds that are non-immunogenic and so must be conjugated to carrier molecules to elicit an immune response. Doses of 50-1000 microg protein conjugate have been suggested for immunisation of rabbits with hapten-protein immunogens. Although larger
