Bronchodilators and anti-inflammatory inhalants

Bronchodilators and anti-inflammatory inhalants (Drugs for asthma)

Drugs are used to both treat and prevent respiratory disease by working against two processes:
1) Spasm on the bronchial muscles (bronchodilators)
2) Inflammation and oedema in mucous membranes (corticosteroids)

These drugs are inhaled  work directly on lung tissue  no or minimal systemic effects
