pioglitazone (Actos)
Tradename: Actos. Genetic August 2012 [18]
Indications:
1) adjunct to diet & exercise to improve diabetic control in patients with diabetes mellitus type 2
2) indicated as monotherapy or for use in combination with sulfonylurea, metformin or insulin
3) may reduce risk of cardiovascular events in diabetics (see PROactive study)
4) may reduce progression of coronary atherosclerosis (see PERISCOPE trial)
5) may reduce risk of subsequent cardiovascular event in patients with insulin resistance (but not diabetes) after ischemic stroke or transient ischemic attack (9 vs 12%) [24]
6) pioglitazone associated with reduced risk of dementia vs non-use in patients with diabetes mellitus type 2 (RR=0.84) [31]
- risk of dementia reduction greater among patients with a history of ischemic heart disease or stroke before diabetes onset (RR=0.46) [31]
7) psoriasis (not FDA-approved use) [8]
8) may be useful in conjunction with imatinib for treatment of chronic myeloid leukemia [22]
9) treatment of nonalcoholic steatohepatitis (NASH) plus prediabetes or type 2 diabetes [26]
Contraindications: (cautions)
- heart failure (see recommendations for prescribing thiazolidinediones)
- unclear whether pioglitazone results in net benefit or harm [23]
- on list on medications to avoid [30]
- heart failure & bone fractures cited
Dosage:
1) start 15 mg PO QD
2) increase by 15 mg QD every 4 weeks
3) maximum dose: 45 mg QD
4) stop after 12 weeks if no benefit
Tabs: 15, 30, 45 mg.
Monitor:
1) ALT every 2 months for 1st year of therapy
-> prior to initiation of therapy then every 3-6 months [9,15]
2) avoid if ALT > 2.5 x upper limit of normal
3) discontinue of ALT > 3 x upper limit of normal or if jaundice occurs
Adverse effects:
1) hepatotoxicity less than troglitazone [6,9]
2) fluid retention & edema
- may exacerbate heart failure [3,5,7]
- may increase risk of heart failure [11]
3) no increase risk of myocardial infarction [11]; risk < rosiglitazone [12,14,17]
4) risk of osteoporosis & fractures in women [13]
- increased risk of bone fractures (RR= 1.5) [29,30]
5) may increase risk of cancer
- increased risk of bladder cancer (dose-dependent) [16,20]
- increased risk of bladder cancer (RR=1.18) not significant after adjustment for potential confounders [21]
- RR = 1.63 after 2 years of use [25]
- not associated with excess risk for bladder cancer [27]
- possible increased risk for bladder cancer [28]
- increased risk for pancreatic cancer (RR=1.41-1.68) [21]
- increased risk for prostate cancer (RR=1.13) [21]
6) increased risk of macular edema (RR = 6.5 at 1 year) [19]
Mechanism of action:
1) thiazolidinedione
2) PPAR-gamma agonist
3) PPAR-gamma regulates transcription of insulin-responsive genes
4) increases peripheral uptake of glucose [23]
5) lowers insulin resistance [24]
6) decreases hepatic glucose production [23]
7) lowers serum triglycerides 9-12% [10]
