Protection by extracellular glutathione against sulfur mustard induced toxicity in vitro

BACKGROUND: Salmeterol xinafoate is a highly selective beta2-adrenoceptor for the maintenance treatment of asthma in adults and children. OBJECTIVE: To review the pharmacokinetics, clinical pharmacology, and therapeutic properties of a recently introduced, long acting antiasthmatic drug. METHODS: Recent English-language publications were selected using Medline as database. RESULTS: Salmeterol's pharmacokinetics, clinical pharmacology, and therapeutic properties are reviewed and aspects related to salmeterol's unusual duration of action, its high potency, beta2-selectivity, possible antiinflammatory actions, its interaction with other drugs, low systemic adverse effects, dosage, and administration are also discussed. CONCLUSION: Salmeterol is a safe long-acting beta2-agonist very useful for maintenance treatment of asthma.
