What is Laadic Injection?
Laadic Injection is a sterile preparation of Diclofenac Sodium 75 mg in a 1 ml ampoule, manufactured by Laafon Galaxy Pharmaceuticals, a WHO-GMP certified pharmaceutical company based in Karnal, Haryana. It is formulated to meet the stringent standards of the Indian Pharmacopoeia (I.P.), ensuring quality and therapeutic efficacy for pain management.

Clinical Indications for Diclofenac Injection 75mg/ml
The intramuscular administration of Diclofenac provides rapid systemic delivery, making it highly suitable for conditions where immediate pain relief is required.
Acute and Chronic Pain Management
Diclofenac injection is highly effective for moderate to severe pain arising from various conditions, including:
- Renal colic (kidney stone pain)
- Migraine attacks
- Acute flare-ups of joint pain or gout
- Dental pain
Post-Surgical Pain and Inflammation
This NSAID injection is a vital component of postoperative pain management protocols. By inhibiting inflammation at the surgical site, it significantly reduces pain and discomfort, particularly following orthopedic, abdominal, and gynecological surgeries. Its efficacy in this area is well-documented in clinical studies.
Inflammatory Conditions
As a potent anti-inflammatory agent, it is used to manage acute exacerbations of chronic inflammatory diseases such as:
- Rheumatoid arthritis
- Ankylosing spondylitis
- Osteoarthritis
Mechanism of Action of Diclofenac 75mg/ml
Diclofenac exerts its therapeutic effects by inhibiting the cyclooxygenase (COX) enzymes, specifically COX-1 and COX-2. These enzymes are responsible for converting arachidonic acid into prostaglandins—compounds that mediate pain, inflammation, and fever. By blocking this pathway, Diclofenac effectively reduces the cardinal signs of inflammation and alleviates pain.

Dosage and Administration Guidelines
For administration by a Registered Medical Practitioner only.
- Standard Adult Dose: 1 ampoule (75mg) administered once daily via a deep intragluteal (intramuscular) injection into the upper quadrant.
- Severe Cases: The dose may be increased to two 75mg injections daily, administered at separate sites.
- Duration: Injectable Diclofenac is generally intended for short-term use (typically not exceeding two days). For continued therapy, treatment should be switched to an oral or rectal formulation.
