Abstract

Lauq is a pharmaceutical dosage form that had been mainly used for the treatment of various respiratory disorders in traditional Persian medicine. It is important from 2 aspects: a dosage form with efficient and optimum delivery of drugs to the respiratory tract and biological effects of its ingredients. Natural medicine in lauq has been demonstrated to act in respiratory disorders by their antitussive, antiallergic, anti-inflammatory, antioxidant, spasmolytic, and antibacterial activities. Some of these natural remedies act by most of the mentioned mechanisms such as Cydonia oblonga, Glycyrrhiza glabra, Crocus sativus, Hyssopus officinalis, Foeniculum vulgare, and honey. However, the evidence is limited including Cassia fistula, Papaver somniferum, and Drimia maritima. According to positive pharmacokinetic and pharmacodynamic aspects of lauqs, they may be considered as efficient dosage forms for delivery of drugs to the respiratory tract. For better compatibility of patients, it could be substituted lauqs with newer drug delivery systems like lozenges. © 2015, © The Author(s) 2015.
