Clinical trials

This study is a randomized, double-blind, placebo-controlled clinical trial designed to evaluate the safety and immunomodulatory effects of Spirulina Blue Protein capsules in healthy adults. Participants will be randomly assigned to receive placebo, 200 mg/day, or 1,000 mg/day of Spirulina Blue Protein capsules for 12 weeks. The study will assess changes in immune cell populations (CD4+, CD8+, and natural killer cells), circulating cytokine levels, hematological and biochemical parameters, and the occurrence of adverse events. The findings will provide evidence regarding the safety and potential immunomodulatory benefits of Spirulina Blue Protein supplementation in healthy individuals and support the development of evidence-based functional food and nutraceutical products.

The goal of this clinical trial is to learn whether a higher dose of cetirizine works better than the standard dose to relieve symptoms of acute urticaria (hives) in adults. The study also aims to learn about the safety of taking a higher dose for a short period of time. The main questions the study aims to answer are: 1. Does the higher dose of cetirizine help people with acute urticaria improve faster than the standard dose? 2. What side effects do participants experience when taking the higher dose? Researchers will compare two groups: one group taking the standard dose of cetirizine (10 mg per day) and another group taking a higher dose (40 mg per day). This will help researchers understand which dose works better and whether the higher dose is safe. Participants will: Take the assigned study medication for 7 days Record their daily symptoms, including itch and hive severity Return for follow-up visits on Day 3, Day 7, and Week 6 Have blood tests to check liver and kidney function before and after treatment This study may help improve treatment options for people with acute urticaria and reduce the need for unnecessary steroid use.
