Introduction to Zyloric (Allopurinol) 300mg
Zyloric (Allopurinol) 300mg is a prescription medicine used to lower high uric acid levels in the body. It is commonly prescribed for conditions such as gout, recurrent uric acid kidney stones, and hyperuricemia associated with certain cancer treatments. This medicine helps prevent the formation of uric acid crystals that can accumulate in joints and kidneys.
Zyloric (Allopurinol) 300mg is classified under Prescription Medicines, Anti-Gout Medicines, Uric Acid Lowering Drugs, and Xanthine Oxidase Inhibitors. It contains Allopurinol, which works by reducing the production of uric acid in the body.
In Bangladesh, Purinol 300mg is available as a local brand containing the same active ingredient Allopurinol, offering a similar therapeutic effect when prescribed by a qualified healthcare professional.
What Is Zyloric (Allopurinol)?
Zyloric is the original brand name of Allopurinol, an oral medicine widely used for the treatment and prevention of conditions caused by excess uric acid.
Allopurinol belongs to a class of medicines known as Xanthine Oxidase Inhibitors. These medicines help reduce uric acid formation and lower the risk of crystal deposits in the joints, kidneys, and urinary tract.
Generic or local brands such as Purinol 300mg contain the same active compound and may be used depending on physician recommendation and regional availability.
Drug Class and Mechanism of Action
Allopurinol is classified as a xanthine oxidase inhibitor with strong urate-lowering properties.
How Allopurinol Works
It works in several ways:
- Reduces the body’s production of uric acid
- Prevents uric acid crystal buildup in joints and kidneys
- Helps reduce the risk of gout attacks and uric acid stone formation
Through these mechanisms, Allopurinol helps control long-term uric acid imbalance and related complications.
How Zyloric Works in the Body
The body naturally breaks down purines from food and cells to form uric acid. When uric acid levels become too high, crystals may form and cause pain, inflammation, or kidney problems.
Key Actions of Allopurinol
- Inhibiting xanthine oxidase, the enzyme responsible for uric acid formation
- Lowering serum uric acid levels over time
- Helping prevent crystal deposition in joints and kidneys
Some local versions such as Purinol deliver the same active ingredient, allowing similar uric acid-lowering treatment when prescribed appropriately.
