<p style="line-height:21.6pt"><span lang="EN" style="font-size:9.0pt;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;;color:#303030">Background: In animal studies, some
<i>ortho</i>-phthalates, including di(2-ethylhexyl) phthalate (DEHP) and di-<i>n</i>-butyl phthalate (DBP), have been shown to be reproductive and developmental toxicants. Human studies show widespread population exposure to background levels of phthalates.
 Limited evidence suggests that particularly high exposure levels may result from orally ingested medicinal products containing phthalates as excipients (inactive ingredients).<o:p></o:p></span></p>
<p style="line-height:21.6pt"><span lang="EN" style="font-size:9.0pt;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;;color:#303030">Objective: In this study we aimed to identify and describe the scope of prescription (RX) and nonprescription (over-the-counter; OTC) medicinal
 products and dietary supplements marketed in the United States and Canada since 1995 that include phthalates as excipients.<o:p></o:p></span></p>
<p style="line-height:21.6pt"><span lang="EN" style="font-size:9.0pt;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;;color:#303030">Methods: We used lists of modified-release drug products to identify potential drug products. Inclusion of phthalates was verified using available
 electronic databases, print references, published package inserts, product packages, and direct communication from manufacturers. Additional products were identified using Internet searches utilizing keywords for phthalates.<o:p></o:p></span></p>
<p style="line-height:21.6pt"><span lang="EN" style="font-size:9.0pt;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;;color:#303030">Results: Based on labeling information, 6 RX drug products included DBP as an excipient, and 45 specified the use of diethyl phthalate (DEP).
 Phthalate polymers with no known toxicity—hypromellose phthalate (HMP), cellulose acetate phthalate (CAP), and polyvinyl acetate phthalate (PVAP)—were included in 75 RX products. Three OTC drug and dietary supplement products listed DBP, 64 listed DEP, and
 &gt; 90 indicated inclusion of polymers.<o:p></o:p></span></p>
<p style="line-height:21.6pt"><span lang="EN" style="font-size:9.0pt;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;;color:#303030">Conclusions: Numerous RX and OTC drug products and supplements from a wide range of therapeutic categories may use DBP or DEP as excipients
 in oral dosage forms. The potential effects of human exposure to these phthalates through medications are unknown and warrant further investigation.<o:p></o:p></span></p>

 information sometimes described products as having an “enteric coating” without a specific listing of the components, making it impossible to determine whether any phthalates were present. Some fish oil capsules labels stated that they “may also contain” a

 their use of phthalates in specific product formulations. Such a list (similar to those available for other excipients such as gelatin or gluten) would not only facilitate critical research on the risks and safety of phthalate-containing medications but also
 would allow prescribers and consumers to select alternative products that are phthalate free. Estimates of exposure from these products can vary according to manufacturer-specific formulation characteristics, including the dosage form, dose, date of use, and
 country of manufacture. Researchers, consumers, and health care providers may need to contact manufacturers directly to confirm the presence of phthalates and the amounts used in a particular drug product.<o:p></o:p></span></p>

<i>ortho-</i>phthalates as excipients, including labels of 50 RX, 40 OTC, and 26 dietary supplement product formulations that listed DEP and/or DBP (9 contained DBP, and 1 contained both DEP and DBP). The potential effects of human exposure to these phthalates
 through medications are unknown and warrant further investigation. The present findings should assist researchers in conducting the necessary studies of risk and safety of phthalates in human populations, but such efforts are limited by the lack of centralized,
 comprehensive, and publically available information on the presence of phthalates in the full range of RX, OTC, and dietary supplement products. Future research should pay particular attention to the amount of phthalate, specifically DBP, used in each dosage
 form so that estimates of exposure from medications and supplements can be quantified.<o:p></o:p></span></p>
