Study type | Observational |
The investigators will conduct a systematic study of the sensory perception of a diverse set of commonly used pediatric liquid medications and excipients in tandem with an equally complete genetic analysis of the adult sensory panelists to investigate the relationship between genetic variation and individual differences in the perceived flavor (taste, smell, irritation) of pediatric medicines. The flavor of each medicine and excipient will be measured individually using both cognitively demanding methods unsuitable for young children and simpler measures validated for use by children. Salivary DNA samples will be collected to carry out genome wide association study (GWAS).

Gender | All |
Age group | 18 Years to 55 Years |
Eligibility | Inclusion Criteria: - Men and women who are between the ages of 18 and 55 years Exclusion Criteria include the following: - For all female participants, a urine pregnancy test will be done on each testing day. Only those with a negative pregnancy test will be allowed to participate in taste testing. - Smokers will be excluded since it alters flavor perception. - Potential subjects will be excluded if they are on drugs with potential serious adverse effects that are mediated through CYP450 3A4 since ritonavir is a potent inhibitor of CYP450 3A4 and could lead to elevated levels of the prohibited drugs if swallowed. The prohibited drugs include the following: - Alfuzosin (Uroxatral; alpha-1-adrenoreceptor antagonist) - Astemizole (Hismanal; antihistamine) - Bepridil (Vascor; calcium channel blocker) - Cerivastatin (Baycol; statin) - Cisapride (Propulsid; GI motility agent) - Dronedarone (multaq; anti-arrhythmic) - Ergotamine (Cafergot, Ergot derivatives) - Flecainide (Tabocor; anti-arrhythmic) - Lovastatin (Altoprev; HMG-CoA Reductase Inhibitor) - Lurasidone (Latuda; antipsychotic) - Midazolam (Versed; sedative/hypnotic) - Pimozide (Orap; antipsychotic) - Ranolazine (Ranexa; anti-anginal) - Simvastatin (Zocor; statin) - Terfenadine (Seldane; antihistamine) - Tinidazole (Tindamax; anti-parasitic) - Trazodone (Desyrel; antidepressant/sedative) - Triazolam (Halcion; sedative) - Warfarin (Coumadin; blood thinner) - Potential subjects will be excluded if they have had current (within the last 24 hours) use of sildenafil (Viagra), tadalafil (Cialis), and verdenafil (Levitra) are also exclusion criteria. These drugs can be used as needed for erectile dysfunction. They are also used as a daily treatment for pulmonary arterial hypertension. With CYP450 3A4 blockade and current use, hypotension, syncope, and prolonged erection are possible. - Potential subjects will be excluded if they have known allergies or hypersensitivity reactions to lopinavir, ritonavir, clindamycin, prednisone, dexamethasone, ibuprofen, 6-mercaptopurine, propylthiouracil, or any of the excipients in the liquid formulations to be tested. |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Flavor ratings (using general labelled magnitude scale, gLMS) of pediatric medicines and excipients | Flavor ratings of each pediatric medicine and excipient as assessed by the general labelled magnitude scale [gLMS]; each medicine and each excipient is rated individually; range 0 [minimum, no flavor] to 100 [maximum; strongest flavor rating] | Through study completion, an average of 3 years | |
Primary | Palatability ratings (using hedonic general labelled magnitude scale, hedonic gLMS) of the flavor of pediatric medicines and excipients | Ratings of the palatabillity of the flavor of each medicine and excipient, as assessed by the hedonic general labelled magnitude scale; each medicine and each excipient is rated individually, range: -100 [minimum palatability rating] to 0 [neither like nor dislike] to 100 [maximum /strongest imaginable palatability ratings] | Through study completion, an average of 3 years | |
Primary | Detect genetic associations (GWAS) with flavor and palatability ratings of pediatric medicines | To detect genetic associations with taste and palatability ratings phenotypes of each medicine | After study completion, 2021-2022 | |
Secondary | Hedonic ratings (using 5 face scale) of the flavor of pediatric medicines | Ratings of the liking of the flavor of each medicine, as assessed by the simpler, hedonic 5-face scale; each medicine is rated individually; range: 1 (minimum, greatest dislike score) to 5 (maximum; greatest liking score). Each panelist's hedonic 5-face scale rating will be correlated with the more sophisticated hedonic gLMS rating for each medicine to lay the foundation for future research in pediatric populations | Through study completion, an average of 3 years |
