Diclofenac Potassium/Diclofenac Sodium

Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, reduce inflammation, and lower fever. It is available in two formulations: **Diclofenac Potassium** and **Diclofenac Sodium**, which differ primarily in their formulation and absorption characteristics. Here’s an overview of their usage:

### Diclofenac Potassium

- **Dosage**: Typically administered at a dose of 50 mg to 100 mg per day, divided into several doses. The specific dosage may depend on the severity of the condition and the patient's response.
- **Onset of Action**: Faster than Diclofenac Sodium; can provide relief within a few hours.

### Diclofenac Sodium
- **Formulation**: Available in various forms, including oral tablets, extended-release formulations, topical gels, and injectable solutions.
