Mechanism and action
Montelukast selectively blocks the CysLT1 receptor, which mediates the action of leukotrienes C4, D4 and E4 — proinflammatory mediators released by mast cells and eosinophils in the airway.
Brands and generics in Chile
In Chile, Montelukast is typically dispensed as one internationally recognised brand along with their corresponding authorised generics. Chilean pharmacies are dominated by three large chains — Cruz Verde, Salcobrand and Ahumada — plus a network of independent farmacias populares run by municipalities. Pharmacist counselling is typically brief at chain dispensing and more thorough at populares. Brand-to-generic substitution is decided by the pharmacist under local ISP (Instituto de Salud Pública de Chile, Public Health Institute) equivalence rules, and the price difference in CLP is usually substantial.
Online and tele-prescribing access
Online medicine sale in Chile is permitted through ISP-registered pharmacies; the three major chains offer mature online platforms with tracked deliveries. Online prescription handling requires uploading a valid receta and pharmacist verification before dispensing. For Montelukast specifically, the legal online options in Chile depend on its Rx-or-OTC classification under ISP (Instituto de Salud Pública de Chile, Public Health Institute).
