BACKGROUND
Antipsychotic drugs frequently cause amenorrhoea and galactorrhoea. Jasmine flowers used topically were as effective as oral Bromocriptine in suppressing puerperal lactation. This study aims to evaluate the efficacy and safety of intranasal jasmine flower extract (JFE) to reduce prolactin levels of patients on stable doses of antipsychotic drugs.
METHODS
This is a randomized, double blind, crossover clinical trial. An aqueous-ethanol extract of jasmine flowers was prepared and used as nasal drops. A decrease in serum prolactin of ≥25 ng/mL was considered a significant response.
RESULTS
Ten out of 35 women had a significant drop in the serum prolactin while on the JFE. The non-responders to JFE were on higher doses of antipsychotic drugs. The main side effect was a transient and mild burning sensation in the nose. A cost analysis favoured JFE over dopamine agonists.
CONCLUSIONS
JFE contains a prolactin-lowering substance which needs further characterisation.
