According to a 2008 consumer survey of individuals who personally imported medicines, 86.3% of them ordered their medicines via the internet, and many imported erectile dysfunction (ED) and anti-obesity medicines [1]. The fact that medicines can be purchased discretely via the internet is popular [[2], [3], [4], [5]]. A big problem with personal importation of medicines is the risk of obtaining falsified medicines that are produced with intentional deviations from the original medicines in terms of composition or origin. The World Health Organization (WHO) has estimated that less than 1% of medicines distributed in developed countries are falsified, but this proportion is much higher in developing countries. In addition, more than half of the medicines purchased from websites that do not provide a contact address are reportedly falsified [6]. WHO defines “substandard and falsified (SF) medical products” as follows: “a) substandard (also called “out of specification”): these are authorized medical products that fail to meet either their quality standards or specifications, or both; b) unregistered/unlicensed: medical products that have not undergone evaluation and/or approval by the National or Regional Regulatory Authority for the market in which they are marketed/distributed or used, subject to permitted conditions under national or regional regulation and legislation; c) falsified: medical products that deliberately/fraudulently misrepresent their identity, composition, or source” [7].

Common side effects of Levitra vs. Viagra

Growing awareness, increased diagnosis rates, and aging populations underpin this growth. Generic sildenafil accounts for roughly 60% of prescriptions, but branded drugs like Levitra are preferred where insurance reimbursement and brand loyalty dominate. Projections indicate that by 2028, sales could reach approximately $250 million globally, driven by continued regional expansion and marketing initiatives. Pricing Strategy: Generics and branded versions compete on price and perceived quality. Bayer’s premium branding limits volume but enhances margins. Although medicines can be imported into Japan via the internet, their quality, effectiveness, and safety are not guaranteed by the Pharmaceutical Affairs Law (PAL) [8].

In falsified medicines, the active pharmaceutical ingredient (API) content may not be correct, and harmful impurities might be present because of deviations from good manufacturing practices [2].

Regulatory Approvals: Variability in approval timelines affects market entry. Levitra’s market has expanded in countries with regulatory pathways, including Asia and Latin America. Patent Challenges: Although Levitra’s original patent expired in Europe in 2013, Bayer maintains patent protections in some jurisdictions, affecting generic competition and market share. Physician and Patient Preferences: Brand recognition influences prescription patterns. Consequently, falsified medicines can present health risks. In addition, it can be difficult to receive treatment for any side effects because doctors and pharmacists will find it difficult to respond promptly when they do not know the ingredients of the falsified medicine [9]. ED medicines, such as Viagra (Pfizer Inc., New York, USA), are reportedly popular on the falsified pharmaceutical market [10]. From 2004–2008, 35 brand levitra price million falsified sildenafil tablets were reported in a survey in the European Union [11].

The purpose of the present research was to examine the quality and authenticity of vardenafil tablets available on the internet.

Websites were selected if they fulfilled one of the following conditions: 1) there was no contact address and/or name given for a responsible person on the website, 2) it was a known criminal website that we had obtained a falsified medicine from previously [ We purchased 22 products with a dose of 20 mg, four products with a dose of 100 mg (an unregistered/unlicensed dose outside of Japan/anywhere in the world/elsewhere in the world), and two products with a dose of 10-mg OD (an unregistered/unlicensed dose in Japan). We obtained 28 products from 15 different websites. The authenticity investigation from Bayer AG (the manufacturer) revealed that 11 of the products (40%) were genuine tablets and 17 of the products (60%) were falsified (Table 1).
