Voltaren SR is a sustained-release formulation of a non steroidal anti inflammatory drug used to relieve pain and inflammation. Its active ingredient is diclofenac sodium, which belongs to the class of cyclooxygenase inhibitors. By blocking cyclooxygenase enzymes the medication reduces the synthesis of prostaglandins that mediate pain, fever and swelling. This inhibition decreases the transmission of nociceptive signals from peripheral tissues to the central nervous system. The sustained-release design maintains an even plasma concentration over several hours allowing prolonged therapeutic effect. The lowered prostaglandin levels also diminish vasodilation and swelling of synovial membranes, improving joint mobility. Consequently the drug alleviates symptoms associated with conditions such as osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. Overall Voltaren SR provides anti inflammatory and analgesic action through selective inhibition of cyclooxygenase pathways.

Voltaren SR contains diclofenac sodium formulated for sustained release and belongs to the class of non-steroidal anti-inflammatory drugs used to relieve pain and inflammation. It works by inhibiting the cyclooxygenase enzymes cox-1 and cox-2 which reduces the synthesis of prostaglandins that mediate pain and swelling. This mechanism provides systemic analgesia and helps decrease joint stiffness in conditions such as osteoarthritis and rheumatoid arthritis. By maintaining a consistent blood concentration over several hours the medication delivers prolonged anti-inflammatory effect. The pharmacokinetics of Voltaren SR allow absorption from the gastrointestinal tract and gradual release into the circulation. The overall therapeutic action is achieved through the suppression of inflammatory mediators that cause discomfort.

Voltaren SR may cause stomach discomfort in many users. Headache is another frequently reported side effect. Some people experience dizziness or lightheadedness. Skin reactions such as rash or itching can occur. Elevated blood pressure has been observed in certain patients. Fluid retention leading to swelling of the ankles or feet is possible. Rarely liver enzyme abnormalities have been detected.

Voltaren SR may cause stomach discomfort or mild nausea in some users. It can lead to headaches or dizziness as occasional side effects. Some individuals experience skin reactions such as rash or itching. Elevated blood pressure has been reported in a minority of patients. Fluid retention and swelling of the ankles can occur with long-term use. Rarely, liver function tests may show temporary abnormalities. Joint pain may persist or worsen despite treatment in certain cases. Most side effects are mild and do not require medical intervention.
