Researchers conducted a systematic review and meta-analysis of 257 randomised controlled trials and summarized the evidence about commonly prescribed drugs and their association with weight change.
They included 257 randomized trials (54 different drugs; 84,696 patients enrolled). Weight gain was associated with the use of: amitriptyline (1.8 kg), mirtazapine (1.5 kg), olanzapine (2.4 kg), quetiapine (1.1 kg), risperidone (0.8 kg), gabapentin ( 2.2 kg), tolbutamide (2.8 kg), pioglitazone (2.6 kg), glimepiride (2.1 kg), gliclazide (1.8 kg), glyburide (2.6 kg), glipizide (2.2 kg), sitagliptin (0.55 kg), and nateglinide (0.3 kg).
Weight loss was associated with the use of: metformin (1.1 kg), acarbose (0.4 kg), miglitol (0.7 kg), bupropion (1.3 kg), and fluoxetine (1.3 kg).
For many other remaining drugs (including antihypertensives and antihistamines), the weight change was either statistically nonsignificant or supported by very low-quality evidence.
