According to a press release, Sinol-M™ (marketed by Sinol USA Inc as Sinol-M™ and Sinol™), a capsaicin nasal spray containing a new component MucoAd®, prolongs contact with nasal surfaces so that the effect lasts longer and repeat dosing is needed less frequently. In a study of 24 patients the capsaicin nasal spray with MucoAd® (Sinol-M™), symptom relief required less total medication, especially at night. The release suggests that the MucoAd® capsaicin nasal spray (Sinol-M™) might permit a better nights sleep, free from rhinitis symptoms. Importantly, no adverse events were noted.
Dr. Michael A. Kaliner, of the Institute of Asthma and Allergy, Wheaton, Maryland, and principal author commented "this study represents the first-ever capsaicin-based treatment for allergic rhinitis to be supported by prospective clinical data, and has important implications for millions of Americans who suffer from nasal allergies. This all-natural product has now been demonstrated to provide clinical effectiveness without any of the side effects associated with intra-nasal steroids and is available without a prescription. It may also provide a new option for patients looking for a zinc-free, all-natural product in the wake of the June 16, 2009 Food and Drug Administration (FDA) warning to consumers to stop using and discard zinc-containing intranasal products (Zicam), due to numerous reports that they may cause a loss of sense of smell (anosmia)."
