About Voltaren SR
Voltaren SR is a prescription-only oral formulation of diclofenac 100 mg, a non-steroidal anti-inflammatory drug (NSAID) that belongs to the phenylacetic acid class. It is approved in Australia for the management of moderate to severe pain associated with musculoskeletal conditions and for chronic inflammatory disorders such as osteoarthritis and rheumatoid arthritis. The sustained-release (SR) tablet is designed to deliver diclofenac steadily over several hours, providing prolonged pain relief while minimizing the peaks and troughs typical of immediate-release tablets. Although its primary indication is for pain and inflammation, clinicians sometimes consider it for other inflammatory pain states under specialist supervision.
What is Voltaren SR?
Voltaren SR is a brand-name, sustained-release tablet that contains the active ingredient diclofenac sodium. The product received approval from the Therapeutic Goods Administration (TGA) in 1995 and is listed on the Australian Pharmaceutical Benefits Scheme (PBS). As a brand drug, it is marketed by Novartis Australia, and generic equivalents of diclofenac 100 mg SR are also available in the Australian market. The medication is classified as a prescription-only medicine (Schedule 4) because of its potential for gastrointestinal, cardiovascular, and renal adverse effects, which require medical oversight.
How Voltaren SR Works
Diclofenac belongs to the arylacetic acid subclass of NSAIDs and exerts its therapeutic effect by reversibly inhibiting the cyclooxygenase enzymes COX-1 and COX-2. These enzymes catalyse the conversion of arachidonic acid into prostaglandins, thromboxanes, and prostacyclins-molecules that sensitize nociceptors, mediate vasodilation, and sustain inflammatory cell recruitment. By dampening prostaglandin synthesis, diclofenac reduces peripheral sensitisation of pain fibres and diminishes the inflammatory cascade that leads to swelling and heat.
The sustained-release matrix in Voltaren SR tablets prolongs diclofenac absorption, achieving a relatively flat plasma concentration curve. Peak plasma levels are typically observed 2-4 hours after ingestion, with an effective therapeutic window that can extend up to 12 hours. The drug is extensively bound to plasma proteins (≈ 99 %) and undergoes hepatic metabolism primarily via CYP2C9 to 4′-hydroxydiclofenac, which is then conjugated and excreted renally. The elimination half-life averages 1-2 hours for the parent compound, but the SR formulation ensures clinically relevant concentrations are maintained longer than immediate-release tablets.
Why Voltaren SR Is Used for Pain Relief and Inflammation
-
Osteoarthritis of the knee, hip, or hand The COX inhibition curtails prostaglandin-mediated joint inflammation, reducing stiffness and allowing improved mobility. Clinical guidelines (e.g., RACGP) place diclofenac among first-line NSAIDs for symptomatic osteoarthritis when paracetamol alone is insufficient.
-
Rheumatoid arthritis (RA) flares Diclofenac’s dual COX activity attenuates synovial inflammation and pain, complementing disease-modifying antirheumatic drugs (DMARDs). The SR formulation enables twice-daily dosing, improving adherence during chronic RA management.
-
Ankylosing spondylitis By lowering spinal inflammation, diclofenac alleviates axial pain and improves function, fitting into treatment algorithms that recommend NSAIDs as the cornerstone therapy for axial spondyloarthritis.
-
Acute musculoskeletal injuries (sprains, strains, low-back pain) The rapid onset of analgesia (≈ 30-60 minutes) provides prompt relief, while the sustained release maintains pain control throughout the day, reducing reliance on multiple dosing of immediate-release NSAIDs.
-
Post-operative pain following minor orthopedic procedures Compared with ibuprofen, diclofenac offers comparable analgesia with fewer dosing intervals, allowing patients to achieve adequate pain control with only two tablets daily.
In each of these conditions, the therapeutic benefit stems directly from diclofenac’s ability to block prostaglandin synthesis, which underlies both nociception and the vascular changes of inflammation. Compared with other NSAIDs, diclofenac demonstrates a slightly higher COX-2 selectivity, a factor that may translate into marginally lower gastrointestinal irritation but a modestly increased cardiovascular risk-an important consideration reflected in Australian prescribing guidelines.
Off-Label and Investigational Uses of Voltaren SR
Evidence from small-scale randomized trials has explored diclofenac SR in migraine prophylaxis and in certain cancer-related pain syndromes. These studies suggest modest reduction in migraine frequency and improved control of bone metastasis pain, yet the data remain limited and the formulations are not approved for these indications by the TGA.
Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Voltaren SR Right for You?
Voltaren SR is most appropriate for adults who require consistent, long-lasting relief from inflammatory pain and whose cardiovascular, gastrointestinal, and renal risk profiles have been evaluated by a prescriber. It is often chosen when twice-daily dosing improves convenience over three- or four-times-daily immediate-release NSAIDs.
The medication may be unsuitable for individuals with a history of peptic ulcer disease, uncontrolled hypertension, severe heart failure, or advanced renal impairment-situations that heighten the risk of serious adverse events. Pregnant or breastfeeding women should avoid diclofenac unless the benefits outweigh the potential fetal or neonatal risks, as recommended by the Australian Medicines Handbook. Elderly patients frequently exhibit diminished renal clearance; dose adjustments or close monitoring are therefore advisable.
In practice, clinicians consider patient-specific factors such as concomitant anticoagulant use, previous NSAID reactions, and the need for consistent analgesia when deciding whether Voltaren SR aligns with therapeutic goals.
Taking Voltaren SR Effectively
- Timing - Take the tablet with a full glass of water after a meal; food mitigates gastrointestinal irritation without markedly delaying the onset of analgesia.
- Dosage - The standard adult regimen is 1 tablet (100 mg) taken twice daily, spaced approximately 12 hours apart. Do not exceed 200 mg per day unless explicitly instructed.
- Missed dose - If a dose is forgotten and the scheduled time is less than 6 hours away, take it as soon as remembered. Skip the dose if it is almost time for the next scheduled tablet to avoid double-dosing.
- Travel - For long journeys, keep the medication in its original packaging to protect from temperature extremes. A short supply (e.g., a 7-day course) is advisable if customs inspections are a concern.
- Drug interactions - Concomitant use of anticoagulants, selective serotonin reuptake inhibitors, or other NSAIDs can increase bleeding risk. While the article does not list contraindications, patients should review their full medication list with a pharmacist.
Understanding Side Effects and How to Manage Them
The most frequent adverse events stem from diclofenac’s inhibition of protective prostaglandins in the gastric mucosa:
- Upper gastrointestinal discomfort (heartburn, dyspepsia) - Take the tablet with food, avoid alcohol and tobacco, and consider a proton-pump inhibitor if symptoms persist.
- Headache - Often mild and transient; hydration and regular sleep patterns can help.
Less common, but clinically important, effects arise from systemic COX-2 inhibition:
- Elevated blood pressure - Monitor BP regularly, especially in patients with pre-existing hypertension.
- Renal function changes - Ensure adequate hydration; check serum creatinine if you have chronic kidney disease.
Serious reactions, though rare, require immediate medical attention:
- Signs of gastrointestinal bleeding (black stools, vomiting blood)
- Cardiovascular events (chest pain, sudden shortness of breath)
- Severe skin reactions (blistering, widespread rash)
If any of these occur, discontinue the medication and seek care promptly. Understanding that most side effects are a direct consequence of prostaglandin suppression helps patients recognise early warning signs and act appropriately.
