Melatonin Interaction Resulting in Severe Sedation.

Purpose: Natural health products (NHPs), including melatonin, are widely used products. Despite the widespread assumption that all NHPs are safe, they contain pharmacologically active substances and can therefore have adverse effects and/or interact with pharmaceuticals.

Objective: To investigate the mechanism underlying NHP interactions identified through the Pharmacy SONAR active surveillance study.

Inhibition of human cytochrome p450 metabolism by blended herbal products and vitamins.

Purpose: The use of supplements as herbal and micronutrient natural health products with conventional health products has become increasingly popular. It has been reported that some herbal products can inhibit the activity of cytochrome P450-mediated metabolism and drug disposition. This study was designed to investigate a case report of a severe adverse event to determine the potential interactions of femMED, Thyrosense and vitamins on cytochrome P450-mediated drug metabolism.

Pharmacists' participation in research: a case of trying to find the time.

Objective  The objective of this case study was to explore how pharmacists involved in the Pharmacy Study Of Natural Health Product Adverse Reactions (SONAR) project perceived the barriers and facilitators to participating in clinical research. Methods  A total of 19 semi-structured interviews were completed with pharmacy staff members who had recently completed data collection in the SONAR study which involved asking patients if they had experienced any unwanted effects while taking natural products. Other data sources included detailed field notes and interviews with SONAR researchers.
