Aprotinin aerosol has been previously shown to have protective effects in experimental influenza- and parainfluenza-induced bronchopneumonias in animals. This paper presents the results of controlled clinical studies to evaluate the therapeutical efficiency of aprotinin aerosol in natural influenza and parainfluenza infections in human beings. A total of 52 patients were followed up. They received either soda (placebo) or aprotinin inhalations thrice a day for 4-5 days. The following mean duration (in days) of symptoms was found in the control (placebo-treated) and aprotinin-treated patients. These were: 2.5 versus 1.8 for fever, 2.0 versus 1.5 for headache, 2.9 versus 1.8 for weakness, 3.9 and 2.8 for common cold, 3.1 versus 1.6 for sore throat, 4.9 versus 2.8 for pharyngeal hyperemia, 4.9 versus 4.0 for cough, and 3.5 versus 1.3 for hoarse voice (p < 0.05). Inhaled aprotinin was well tolerated by the patients and caused no topical irritating effects and allergic reactions. The findings demonstrate the noticeable clinical efficacy of aprotinin aerosol in human influenza and parainfluenza.

The new virus SARS-CoV-2 is savagely spreading out over the world. The biologic studies show that the target receptor for the virus might be angiotensin-converting enzyme 2 (ACE2). This peptide is responsible for converting angiotensin II (Ang II), which is a profoundly active peptide, into Ang 1-7 with quite a balancing barbell function. It is emphasized that the direct target of the virus is ACE2 underlining the obvious difference with ACE. Nevertheless, we hypothesized that a back load build up effect on Ang II may usurp the ACE capacity and subsequently leave the bradykinin system unabated. We think there are clinical clues for dry cough and the presumed aggravating role of ACE inhibitors like captopril on the disease process. Thereby, we speculated that inhibition of bradykinin synthesis and/or blockade of bradykinin B2 receptor using Aprotinin/ecallantide and Icatibant, respectively, may hold therapeutic promise in severe cases and these molecules can be advanced to clinical trials.
