Loxonin S Series (Quick / Premium) – Daiichi Sankyo Healthcare

The Loxonin S line of over-the-counter antipyretic analgesics provides fast, effective, and gentle relief from pain and fever.
Both formulations feature loxoprofen sodium hydrate, a clinically proven NSAID that suppresses prostaglandin production to alleviate inflammation, pain, and fever.

• Loxonin S Quick: Formulated with Quick Break Technology for rapid tablet disintegration and faster onset of relief.

• Loxonin S Premium: Enhanced with allylisopropylacetylurea and anhydrous caffeine for greater pain-relief efficacy and mental alertness, while magnesium aluminometasilicate protects the stomach.

Both variants are non-drowsy, easy to swallow, and designed for quick absorption with reduced gastric burden.
