Titanium dioxide overlayer

Another example, which demonstrates the importance of the spectral overlay principle, is the fact that film coatings containing titanium dioxide provide sufficient protection for molsidomine (Thoma K, Aman W. In preparation) (4), whereas nifedipine tablets coated with such films still show photodegradation (19).
