Regular laxative use may be correlated with dementia, according to research published in the journal Neurology in February. The study looked at a cohort of 502,229 British adults participating in UK Biobank, a long-term initiative that gathered extensive genetic and health information from 40- to 69-year-olds in England, Wales and Scotland between 2006 and 2010. The participants had no history of dementia. Researchers compared those who reported no regular laxative use with those who said they used laxatives most days of the week for the past four weeks in surveys. (Blakemore, 3/4)

Eli Lilly would’ve had to pay Medicaid about $150 for each vial of insulin used in the program if it hadn’t dramatically cut the list prices for some of its older products this week. The company was about to run into a Medicaid penalty for hiking the price of its drugs faster than the rate of inflation. Now that it plans to lower the list price of the insulin Humalog 70%, it won’t trigger that penalty. Lilly also is lowering the price of Lispro, a biosimilar of Humalog, to $25 a vial.

KHN: Despite Pharma Claims, Illicit Drug Shipments To US Aren’t Full Of Opioids. It’s Generic Viagra.

For years, the FDA has defended its efforts to intercept prescription drugs coming from abroad by mail as necessary to keep out dangerous opioids, including fentanyl. The pharmaceutical industry frequently cites such concerns in its battle to stymie numerous proposals in Washington to allow Americans to buy drugs from Canada and other countries where prices are almost always much lower.
