2. Duration of Therapy
Inhalational anticholinergic agents are suitable for chronic administration as side effects are minimal and drug effectiveness is maintained over years of regular, continuous use. Since inhalation anticholinergics are indicated in the management of chronic, lifelong diseases, there is no basis for limiting the duration of therapy. However, days’ supply for each MDI anticholinergic canister is limited based on the number of inhalations per canister as well as the maximum recommended dose per day. Days’ supply for inhalational anticholinergic therapy is summarized in Tables 4 and 5, based on the maximum recommended dose and the number of actuations per canister or number of capsules per blister card listed in Tables 1-3. Excessive use may be identified based on refill frequency. Inappropriate supply of inhaled anticholinergic agents will be monitored by reviewing excessive refills.
