Breve relato das pesquisas sobre a farmacologia humana da ayahuasca

Notícia enviada por Rafael Santos, de Barcelona (Espanha).

"A equipe dos Doutores Jordi Riba e Manel J. Barbanoj, M.D., do Centre d'Investigació del Medicament, Institut de Recerca, Hospital de la Santa Creu i Sant Pau, Barcelona, Espanha, vem realizando os mais recentes estudos sobre os efeitos neuroendócrinos, neurofisiológicos e neuroquímicos da ayahuasca, utilizando técnicas avançadas de neuroimagem, monitoramento do sono e quantificação-qualificação dos alcalóides no sangue e urina de voluntários sadios.

Ayahuasca in progress

Pharmacological, imaging and immunological studies of Ayahuasca in Healthy Volunteers

A study of the urinary excretion of ayahuasca alkaloids in the 22-volunteer, double-blind study (described below) is planned but has not yet been conducted due to lack of funding. The double-blind brain-imaging study using SPECT to study regional cerebral blood flow after ayahuasca administration has been fully approved and is now in progress. As of this date, seventeen volunteers have undergone all experimental sessions. This study will also look for any immuno modulating effects of ayahuasca. These studies are seeking additional information on mechanisms of action underlying the central effects of ayahuasca.

Ayahuasca under development

Pharmacological Study of Ayahuasca in Healthy Humans

A repeated dose study and a neurochemical mechanism study designed to evaluate the capacity of 5HT1A agonists and 5HT2A antagonists to block the effects of ayahuasca will both be conducted soon. These studies are also included as part of the program of research including a SPECT study of regional blood flow after ayahuasca that is already inprogress, as described above.
