Pharmacokinetic and pharmacodynamic characteristics of hydroxychloroquine:

• Its mechanism of action is poorly understood.
• It may inhibit the pH-dependent entry of certain viruses into host cells or block viral replication by inhibiting the glycosylation of envelope proteins.
• It exhibits anti-inflammatory and immunomodulatory activities.
• It can increase the QT interval.
• It has hypoglycemic effects in non-diabetic patients.
• It accumulates in blood cells.
• It has a high volume of distribution, indicating extensive tissue penetration.
