Many new ideas for formulating drugs for passage across the skin are under investigation, including the use of 'nanocarriers' and other sophisticated chemical measures (see Reis et al., 2017). The obstruction usually causes wheeze and merits drug treatment, 2 although the natural history of asthma includes spontaneous remissions. Chapter 38: metabolism and excretion of drugs. 23), increases the force of contraction of the heart by binding troponin C and sensitising it to the action of Ca2+.
