Pharmacokinetic and Tolerance Study of Meloxicam Eye Drops in Healthy Volunteers

Pharmacokinetics and Tolerance of Meloxicam Eye Drops in Healthy Volunteers, a Phase I , Single-dose and Multiple-dose, Open-labeled Clinical Trial

The pharmacokinetics, safety, and tolerability of meloxicam eye drops in Chinese healthy volunteers were evaluated to provide a basis for the formulation of a phase II clinical trial dosing regimen for this product. Including pre-tests and formal trials, formal trials include single-dose pharmacokinetics tests and multiple-dose tolerance tests (4 times a day for 3 consecutive days).

Study Overview

• Status: Unknown
• Conditions: Healthy Volunteers
• Intervention / Treatment: Drug: Meloxicam

Detailed Description

Meloxicam eye drops is a new class 2 drug of the country. The main ingredients are meloxicam. The other ingredients are hydroxypropyl-β-cyclodextrin, sodium hydroxide, boric acid, sodium chloride and water for injection. Among them, hydroxypropyl-β-cyclodextrin can increase the solubility of meloxicam and improve the stability of the solution. The indication of meloxicam eye drops is non-infectious ocular inflammation, especially for inflammation and complications after cataract surgery. The possible adverse reaction is transient tingling in the eye after eye drops.

Meloxicam is a non-steroidal anti-inflammatory drug (NSAIDS) that selectively inhibits COX-2 cyclooxygenase. It is currently widely used in the treatment of acute and chronic inflammation and pain, and its mechanism of action is to prevent the production of prostaglandins (PGs) that cause inflammation by inhibiting cyclooxygenase (COX). Non-infectious ocular inflammation is usually caused by the synthesis and release of inflammatory mediators such as prostaglandin (PG) after eye tissues are stimulated. Because non-steroidal anti-inflammatory drugs have anti-inflammatory, anti-allergic and analgesic effects, and have no adverse effects of glucocorticoids, their application in ophthalmology has been valued.
