In the second half of 20^th century the accessibility of potential asthma drugs is increased. For the treatment of respiratory disease the drugs are delivered directly to the lungs thereby availability is convenient, portable delivery systems origins of inhalation therapy can be traced back to the early civilizations .This route of administration was unusual until recently. It was discovered that the large highly absorptive surface area of the lung can be used for systemic delivery of proteins such as insulin in the search for non-invasive delivery of biologics. New delivery systems with efficiency and reproducibility to match the high level and therapeutic constraints of biologics are currently in late stage clinical trials. Straight small molecular weight drugs previously administered by injection are tested through the inhalation route either to provide non-invasively rapid onset of action, or to improve the therapeutic ratio for drugs acting in the lung. Gene therapy of pulmonary disease is still in its initial stages but could deliver valuable solutions to currently unmet medical needs. The establishing of the new period is therefore likely to spectator development of many valuable therapeutic products provided by inhalation.

Pre-clinical metabolism & pharmacokinetic aspects are crucial in lead generation and optimization. The most important determinants of the pharmacokinetic profile of a drug are metabolism by the host organism. High metabolic charge regularly hints to poor bioavailability and high clearance. The development of active or toxic metabolites will have an impact on the pharmacological and toxicological outcomes and there will be also possible for drug-drug interactions with administered drugs due to inhibition and /or induction of drug metabolism pathways. Thereby, optimization of the metabolic liability and drug-drug interaction potential of the new chemical entities are certain of the greatest crucial steps during the drug discovery process. The rate and site of metabolism of new chemical entities by drug metabolizing enzymes are approachable to modulation by appropriate structural changes. In the same way, the potential for drug-drug interactions can also be lessened by appropriate structural modifications to the drug candidate. Yet, the optimization of the metabolic stability and drug-drug interaction potential during drug discovery stage has been mostly by empirical methods and by trial and error.
