Recent clinical evidence of the efficacy and safety of thiamphenicol glycinate acetylcysteinate and thiamphenicol glycinate
Abstract
Thiamphenicol is a broad-spectrum antimicrobial agent active against penicillin-resistant Streptococcus pneumoniae, Staphylococcus aureus VISA strains, most methicillin-resistant isolates and atypical pathogens such as Mycoplasma pneumoniae and Chlamydia pneumoniae). Thiamphenicol is present as glycinate hydrochloride (TG) and glycinate acetylcysteinate (TGA) esters in the parenteral and aerosol dosage form. This multicenter, double-blind, randomized clinical trial aimed to evaluate the efficacy and tolerability of aerosol administration of TGA, compared to TG, in the treatment of acute and/or exacerbated infections of the respiratory tract. Results showed that both treatments ameliorated the symptoms (frequency and severity of cough, difficulty in expectoration) associated with the evaluated pathologies, i.e. tracheobronchitis, acute and exacerbated chronic bronchitis. The investigators rated both treatments Good or Very Good in 90% of patients at the end of treatment, with "Very Good" for patients treated with TGA (37%) compared to 28% of patients treated with TG. Both treatments were well tolerated with fewer than 5% of patients experiencing an adverse event.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
