Efficacy, side-effects, plasma and blood levels of maprotiline (Ludiomil)

The Journal of International Medical Research

Two trials of maprotiline (Ludiomil) were performed in general practice. In the first study depressed patients were given either 75 mg of maprotiline in a single dose or 25 mg three times daily. Assessments of the severity of depression and of side-effects were made initially and following 1, 2 and 4 weeks' treatment. At each assessment measurements of plasma levels of maprotiline were made. A second trial was performed in which some patients receiving 75 mg single dose of maprotiline had whole blood levels of maprotiline assayed. Steady-state levels of maprotiline were achieved after one week but these levels showed considerable individual variability. No clear correlation emerged between clinical response, side-effects and plasma or blood levels. Some of the factors which may be responsible are discussed.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
