PROBLEM: Paragraph: The relative bioavailability of nicotine from a nasal spray was assessed in 15 smokers suffering a common cold and rhinitis according to generally accepted criteria. The patients were given a single dose of 2 mg nicotine from the nasal spray with and without concurrent administration of a nasal vasoconstrictor decongestant, xylometazoline, in randomised order. Control session measurements were made in the disease-free state. Applying strict bioequivalence criteria, we found that common cold/rhinitis slightly reduced the bioavailability of nicotine, both in its rate and extent; the geometric mean of the ratio of Crnax , AUC and tma x were 0.81, 0.93 and 1.36, respectively. The nasal vasoconstrictor, xylometazoline, normalised the extent of the bioavailability of nicotine, but further prolonged the time for absorption to almost twice that measured in the disease-free state, increasing the tma x ratio to 1.72. The results suggest that a minor proportion of people stopping smoking with the help of a nicotine nasal spray may experience a minor reduction in the effect of the spray during common cold/rhinitis. However, the nicotine self-titration behaviour found with most smoking cessation products (except the nicotine patch) will automatically lead to an adjustment of the dosage to achieve the desired effect.

SOLUTION: False

PROBLEM: Paragraph: Introduction Significant teratogenic effects have been demonstrated in all animal species exposed to ribavirin. Ribavirin is prescribed for chronic hepatitis C and is contraindicated in women who are pregnant and in the male sexual partners of women who are pregnant. Both sexes are advised to avoid pregnancy for 6 months after exposure. The Ribavirin Pregnancy Registry was established in 2003 to monitor pregnancy exposures to ribavirin for signals of possible human teratogenicity. Methods This voluntary registry enrolls pregnant women with prenatal exposure to ribavirin. Exposure is classified as direct-women taking ribavirin during pregnancy or the 6 months prior to conception-or indirect-women exposed through sexual contact, 6 months prior to or during pregnancy, with a man who is taking or has taken ribavirin in the past 6 months. Women are followed until delivery and infants for 1 year. When enrollment is complete, birth defect rates will be compared with the Metropolitan Atlanta Congenital Defects Program's

PROBLEM: Paragraph: Chronic hepatitis B virus (HBV) infection is a major public health problem worldwide. Although nucleos(t)ide analogs inhibiting viral reverse transcriptase are clinically available as anti-HBV agents, emergence of drug-resistant viruses highlights the need for new anti-HBV agents interfering with other targets. Here we report that cyclosporin A (CsA) can inhibit HBV entry into cultured hepatocytes. The anti-HBV effect of CsA was independent of binding to cyclophilin and calcineurin. Rather, blockade of HBV infection correlated with the ability to inhibit the transporter activity of sodium taurocholate cotransporting polypeptide (NTCP). We also found that HBV infection-susceptible cells, differentiated HepaRG cells and primary human hepatocytes expressed NTCP, while nonsusceptible cell lines did not. A series of compounds targeting NTCP could inhibit HBV infection. CsA inhibited the binding between NTCP and large envelope protein in vitro. Evaluation of CsA analogs identified a compound with higher anti-HBV potency, having a median inhibitory concentration <0.2 lM. Conclusion: This study provides a proof of concept for the novel strategy to identify anti-HBV agents by targeting the candidate HBV receptor, NTCP, using CsA as a structural platform.
