Availability of buprenorphine/naloxone films and naloxone nasal spray in community pharmacies in Texas, USA.

BACKGROUND AND AIMS

Patients with opioid use disorder (OUD) must be able to obtain prescribed buprenorphine/naloxone films (BUP/NX) and naloxone nasal spray (NNS) from a pharmacy promptly to reduce risk for a recurrence of use and subsequent morbidity and mortality. Telephone audits have identified concerning gaps in availability of NNS within US pharmacies, but the availability of BUP/NX has not been rigorously evaluated. This study estimated the availability of BUP/NX and NNS in the US state of Texas and compared availability by pharmacy type and metropolitan status.

DESIGN

A cross-sectional telephone audit with a secret shopper approach conducted from 18 May 2020 to 7 June 2020. Setting and Participants A random sample of 800 of 5078 (16%) community pharmacies licensed with the Texas State Board of Pharmacy.

MEASUREMENTS

Primary outcomes included availability of a 1-week supply of generic BUP/NX 8/2 mg films and a single unit of NNS 4 mg, overall and by pharmacy type. Secondary outcomes included willingness and estimated time-frame to order BUP/NX if unavailable.

FINDINGS

Data from 704 pharmacies (471 chain, 233 independent) were included for analyses. Of these, 34.1% of pharmacies (45.0% of chains versus 12.0% of independents, P < 0.0001) were willing and able to dispense a 1-week supply of generic BUP/NX and a single unit of NNS. BUP/NX alone was available in 42.2% of pharmacies (52.4% of chains versus 21.5% of independents, P < 0.0001). NNS alone was available in 60.1% of pharmacies (77.9% of chains versus 24.0% of independents, P < 0.0001). Of the 397 pharmacies with generic BUP/NX unavailable, 62.2% of pharmacies (73.9% of chains versus 48.0% of independents, P < 0.0001) indicated willingness to order.

CONCLUSIONS

Most pharmacies in Texas do not appear to be willing and able to dispense prescribed buprenorphine/naloxone films and naloxone nasal spray to patients with opioid use disorder in a timely manner. Deficiencies in availability are markedly more pronounced in independent pharmacies compared with chain pharmacies.
