The agency wrote in a clarification aimed at compounders that Lilly said it can meet the “present and projected national demand” and that compounders are restricted from making the products.
Nevertheless, patients and prescribers may still see “intermittent localized supply disruptions as the products move through the supply chain,” the FDA noted.
The Alliance for Pharmacy Compounding (APC) responded swiftly, alerting its members and the public to the resolved shortage and stating that compounders “must immediately cease preparing and dispensing compounded copies” of the two drugs.
However, APC CEO Scott Brunner added it often takes a long time for FDA-approved versions of the drug to become widely available to wholesalers, hospitals, and clinics. Even after Lilly announced greater availability for the drugs, including in a new vial format for low doses, “for most pharmacies, they’re lucky to get two or three boxes of Zepbound a day from their wholesaler — for a patient waiting list that can number in the hundreds.”
“We have already heard this morning from APC members that they are unable to fill orders for their patients,” he said.
Furthermore, he contended, “I suspect plenty of patients taking compounded tirzepatide are going to be caught flat-footed by this. They are being cut off cold turkey, their prescription no longer fillable. They’ll need to get in to see their provider to get a new prescription, and that will take some time. It’s possible that so many patients presently taking compounded GLP-1s [glucagon-like peptide 1] will be eventually switched to the FDA-approved versions — if they can afford them, of course — that it will push tirzepatide injection back into shortage.”
Commenting on the shortage resolution, endocrinologist Beverly Tchang, MD, DABOM, an assistant professor of clinical medicine at Weill Cornell Medicine in New York City told this news organization, “we are not yet experiencing relief from the shortages, but I hope this resolves at least one barrier to access for our patients.”
“I don’t think it will create confusion,” she said. “Fortunately or unfortunately, patients and clinicians are adept by now with therapeutic transitions because we’ve been forced to do so whenever insurance withdraws coverage or a shortage recurs or a coupon expires. It’s obviously not ideal but patients are motivated and clinicians don’t give up.”
This news organization has previously reported on the impact of the shortages and how endocrinologists and obesity medicine specialists were handling them, in light of concerns about compounding pharmacies that may or may not be well founded.
Dr. Tchang declared that she is an adviser to Novo Nordisk.
