During the last decade, the efficacy of arsenic trioxide in both newly diagnosed and relapsed patients with APL 3 has been established. Arsenic trioxide can be used as a single agent and induces complete remissions with only minimal myelosuppression (1) (2, 3, 4, 5) . In one study (2) (1) .Additional studies conducted in the United States confirmed that low doses of arsenic trioxide can induce complete remission in relapsed APL patients.hite arsenic or arsenic trioxide (As 2 O 3) is produced by heating realgar (10) . Arsenic is rarely found in a pure state; rather, it exists in both trivalent and pentavalent oxidation states as a chemically unstable sulfide or oxide, or as a salt of sodium, potassium, or calcium (11) .
The most common statin side effects include: 1  Headache. 2  Difficulty sleeping. 3  Flushing of the skin.  Muscle aches, tenderness, or weakness 1  (myalgia) Drowsiness. 2  Dizziness. Nausea or vomiting.  Abdominal cramping 1  or pain. Bloating 2  or gas. 3  Diarrhea. Constipation.  Rash.
During the follow-up period, 246 (38.9%) patients discontinued statin therapy; the discontinuation rates were similar for both statins (P = 0.544). Seventy-one (28.8%) patients stated mild adverse effects -- such as dyspepsia, fatigue, headache and myalgia -- as the reason for statin interruption. No instance of major adverse event was reported.
