Diclofenac SR 100 mg

Product Overview

Diclofenac SR 100 mg is a sustained‑release tablet formulated by Cipla Limited, a globally recognised pharmaceutical manufacturer. The product belongs to the therapeutic class of non‑steroidal anti‑inflammatory drugs (NSAIDs) and is specifically indicated for the management of musculoskeletal pain, rheumatic discomfort and general pain relief. Each strip contains ten tablets, and the pack is available in multiple strengths including 60, 90, 120 and 240 tablets, allowing patients to choose a supply that matches their treatment duration.

What is Diclofenac SR 100 mg

Diclofenac SR stands for sustained release, meaning the active ingredient is released gradually over an extended period, maintaining therapeutic levels in the bloodstream. The 100 mg strength provides a balanced dose that is effective for moderate to severe acute or chronic pain while minimizing the frequency of dosing. The tablet is intended to be swallowed whole and should not be crushed or split, as this could compromise the controlled‑release mechanism.

Uses and Benefits

The therapeutic benefits of Diclofenac SR 100 mg include reduction of inflammation, alleviation of pain, and improvement of joint mobility. Clinically, it is prescribed for conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis and other inflammatory disorders affecting the spine, hips, knees and hands. Patients often report a quicker return to daily activities and an enhanced quality of life when the medication is used as part of a comprehensive pain management plan.

From a patient perspective, the sustained‑release formulation offers convenience, requiring only one or two doses per day depending on the physician’s recommendation. This dosing simplicity can improve adherence, especially for individuals with busy lifestyles or chronic conditions that require long‑term treatment.

Long‑term treatment with Diclofenac SR has been shown to improve physical function and reduce the need for rescue medication in patients with chronic rheumatic conditions. Clinical studies indicate that sustained pain control contributes to better sleep quality, reduced fatigue and enhanced participation in physiotherapy programs, thereby supporting a holistic approach to disease management.

How It Works

Diclofenac exerts its pharmacological effect by inhibiting the cyclooxygenase enzymes COX‑1 and COX‑2, which are responsible for the synthesis of prostaglandins—chemical mediators that promote inflammation, swelling and pain. By decreasing prostaglandin production, Diclofenac reduces the inflammatory response at the site of injury or disease. The sustained‑release technology ensures a steady plasma concentration of the drug, prolonging its anti‑inflammatory action for up to 24 hours.

Pharmacokinetic studies indicate that after oral administration, Diclofenac is rapidly absorbed, reaches peak plasma concentrations within one to two hours, and is extensively metabolised in the liver before elimination primarily through the kidneys. The sustained‑release coating delays the release of the drug, providing a more stable therapeutic profile compared with immediate‑release formulations.

Dosage Guidelines

Dosage should always be individualized by a qualified healthcare professional. In adult patients, the typical regimen involves one 100 mg tablet taken twice daily, preferably with food to reduce gastrointestinal irritation. The exact frequency may be adjusted based on the severity of the condition, patient tolerance and any concomitant medications. Patients should not exceed the prescribed daily amount and should follow the instructions printed on the packaging or provided by their prescribing clinician.

For optimal efficacy, the tablet should be swallowed whole with a full glass of water. If a dose is missed, the patient should not double up the next dose; instead, they should resume the regular dosing schedule. It is advisable to keep a medication diary to track dosing times and any observed effects.

Side Effects

Like all medicinal products, Diclofenac SR 100 mg may cause adverse reactions, although most are mild and transient. Common side effects include gastrointestinal discomfort such as heartburn, nausea, or dyspepsia, as well as headache, dizziness or mild skin rash. Less frequently, patients may experience elevated blood pressure, liver enzyme abnormalities or renal function changes. If any of these symptoms persist or worsen, medical attention should be sought promptly.

Serious adverse events, though rare, can include gastrointestinal bleeding, severe allergic reactions (anaphylaxis) and cardiovascular events such as myocardial infarction or stroke, particularly in patients with pre‑existing cardiovascular disease. If any of these serious symptoms occur, discontinue use and seek immediate medical care.

Healthcare providers should assess cardiovascular risk factors before initiating therapy, especially in patients with a history of hypertension, diabetes or high cholesterol, as NSAIDs may modestly increase the likelihood of major adverse cardiovascular events.

Warnings and Precautions

Prior to prescribing Diclofenac SR 100 mg, clinicians should evaluate the patient’s medical history for contraindications, including known hypersensitivity to Diclofenac or other NSAIDs, active peptic ulcer disease, severe heart failure, or recent cardiovascular surgery. The drug is contraindicated in the third trimester of pregnancy and should be avoided during breastfeeding unless explicitly advised by a healthcare provider.

Patients should be instructed to avoid concomitant use of other NSAIDs, aspirin at low doses for antiplatelet therapy, or corticosteroids without medical supervision, as these combinations may increase the risk of gastrointestinal bleeding. Alcohol consumption should be limited, as it can exacerbate stomach irritation. Regular monitoring of blood pressure, kidney function and liver enzymes is recommended during long‑term treatment.

Frequently Asked Questions

• Q1: How quickly does Diclofenac SR relieve pain?
  A: Pain relief can be noticed within a few hours after the first dose, but the full anti‑inflammatory effect may take several days of consistent use.

  A: It is generally not recommended to combine Diclofenac with other NSAIDs or strong analgesics without physician guidance, to avoid overlapping toxicity.
• Q3: Is the medication safe for elderly patients?
  A: Elderly individuals may be more susceptible to gastrointestinal and cardiovascular side effects; dose adjustments and close monitoring are advised.
• Q4: Does Diclofenac SR interact with blood thinners?
  A: Yes, concomitant use with anticoagulants such as warfarin can increase bleeding risk; medical supervision is essential.
