Online Pharmacies Selling Prescription Drugs
Edit
This entry is adapted from the peer-reviewed paper 10.3390/pharmacy10020042

Almost half of the online pharmacies are not properly regulated and fraudulent issues were uncovered. To address this issue, stricter regulation by World Health Organization and implementation should be carried out together with frequent monitoring of the licensure system and pharmacy verification on every online pharmacy, this would reduce the number of illegal or illegitimate online pharmacy. 

internet pharmacy prescribed medication medication safety patient safety counterfeit medicine

1. Introduction

The number of online pharmacies has been rising over the years. The internet has allowed patients and consumers to buy a range of medicinal products from online pharmacies at a comparatively lower cost than from retail pharmacies. However, some illicit websites based in many countries have been posing as legal pharmacies and are taking advantage of the internet [1] to sell adulterated drugs and low-quality medications [2]. In addition, some medicines are sold illegally without the need for prescriptions [2]. This phenomenon should be a cause for concern since low quality medicines can be unsafe. Furthermore, unsupervised and self-medication use of drugs may expose consumers to harmful adverse effects and increase the risk of morbidity and mortality [3].
The availability of and accessibility to substandard and counterfeit drug products may differ among countries. Countries with good pharmaceutical regulatory and quality assurance systems generally have a lower prevalence of fake or counterfeit products compared to countries with poor regulatory systems. For instance, the availability of counterfeit drugs in Japan and South Korea is low, but it is high in countries such as China and India [4][5]. A large number of counterfeit and fake medicines have been reported to be available in the markets [6]. India has been reported to have the highest prevalence of manufactured counterfeit drugs, which is up to 35%, followed by Nigeria (23.1%) and Pakistan (13.3%) [4]. Nevertheless, counterfeit drugs can still be available from the black market in countries with advanced pharmaceutical regulatory systems [7].
The World Health Organization (WHO) has identified several factors influencing the availability of counterfeit drugs in the black market. These factors include poor national regulation for drug distribution and manufacturing, limited enforcement of drug legislation, poor penal sanctions for violations of drugs legislation and poor regulation among the exporting countries [4]. Other important factors include the complex transactions involving many intermediaries, the high demand and cost for curative and prophylactic drugs, and inefficient collaboration among stakeholders [4].
There is increasing patronage of online pharmacies and the reasons include the convenience of accessing pharmaceutical drugs from these online platforms and their comparatively lower cost than products obtained from physical pharmacies [8]. Nevertheless, issues regarding the quality of online prescription drugs have been a major public health concern. In addition, the legitimacy of online pharmacies selling pharmaceutical drugs may be questionable [9]. Most importantly, there are concerns regarding the safety of consumers since inappropriate use of prescription drugs may cause potential harm [10][11].

2. Current Insights

2.1. Types and Characteristics of Online Pharmacies

2.1.1. Prescription Requirement

The prescriptions submitted to online pharmacies were usually faxed or emailed as a scanned copy. Some online pharmacies request an updated prescription. This entry confirmed several findings documented in the literature, emphasising how medicines, including prescription-only drugs, are obtained online with or without prescriptions [12][13][14]. It is of note that some consumers intentionally procure prescription medications online without a prescription, especially from rogue pharmacies [1][15]. Most of the drugs are purchased to manage chronic conditions such as psychiatric and cardiac disorders [16][17].
Patients with mental disorders have higher tendencies to engage in self-diagnosis and self-medication [12][18][16][19]. Hence, studies conducted on the sale of psychiatric drugs found that patients with mental illness used online pharmacies to stock in drugs believed to be effective in managing their condition. In addition, even when a prescription is available for the drugs, the consumer might still misuse it by sending a single prescription to multiple online pharmacies [20]. The prescription requirement is an important criterion that should be obeyed. However, it is equally vital for prescribed drugs to be procured. Reusing or misusing prescriptions will increase accessibility to prescription drugs, which may put the consumer at risk. Therefore, strategies should be put in place to prevent multiple uses of one prescription through online pharmacies. On that note, only the original prescription should be accepted by online pharmacies, rather than permitting the use of scanned copy via fax or email.

2.1.2. Presence of Online Questionnaire

The need for a consumer to complete a questionnaire to be completed in addition to a prescription before online drug purchase has been re-established by some studies [21][22]. According to these researchers, the questionnaire is a medium to boosting consumers’ confidence regarding the regulatory standards of an online pharmacy. Contraindications and interactions of medicines may occur in patients if they are not well-informed about the drug before online procurement. For instance, patients may bypass the online instrument or questionnaire through a default process without entering any patient-specific information. These events highlight the importance of questionnaires during online drug purchase. Nevertheless, large amounts of prescription medicines could still be ordered online with unverified patient questionnaires [21][23].
Another practice that might heighten patient risk and compromise their safety is the use of pre-selected answers on online questionnaires. Pre-selected questionnaires are easily completed and facilitate rapid approval of drug purchase or treatment without the consumer or patient comprehending the questions. In the same vein, pre-selected answers increase the likelihood of a patient skipping a question unintentionally, leading to a ‘false positive’ outcome. This will eventually compromise patient safety [24][25][26].

2.1.3. Contact Details

A large percentage of online pharmacies display their contact details [27][28]. A study revealed that 37% of pharmacies provide a telephone number for costumers’ enquiries [29]. So, it seems appropriate for patients to test any telephone numbers provided for authenticity before they make a purchase. Bessel et al.’s findings revealed that only 35% of their online pharmacies had published the owners’ or the director’s name [30]. In order to combat this problem, it is recommended that each country’s pharmacy board or regulatory system should conduct a proper investigation of the locally available online pharmacies and systematically check their websites through the provided contact details.

2.1.4. Geographical Information

Consumers are able to engage in the personal importation of these drugs from other countries. Nevertheless, they may or may not be legally allowed because most countries have no proper legislation to either allow or prohibit online pharmacies [3]. Legitimate pharmacies are mostly located in Europe and the United States [25]. Based on the results, the most common locations mentioned by almost half of the online pharmacies were the United States, Canada and the United Kingdom. A few respondents stated that online pharmacies requiring valid prescriptions are more likely to reveal their geographical locations than rogue ones [27][22].

2.1.5. Delivery Information

Regarding the websites used for online drug procurement, 42% of them declared the origin and destination of the products [12]. Among the websites publicising such information, 47% of them were in Asia (47%) [25]. However, some products were delivered for free. The average waiting time for the medication delivery was eight days [25]. Another study highlighted that several purchased drugs were shipped from a different place than the one indicated on the website [1]. Lagan et al. mentioned that out of eight purchasing requests, seven were successfully delivered. One of the requests was not delivered because the online transaction was rejected. This was further attributed to credit card blockade as the delivery company was blacklisted [31].

2.1.6. Drugs Offered

The drugs offered were sildenafil, obesity reduction medications, benzodiazepines, painkillers, antidepressants and antibiotics. Some studies focused on specific classes of drugs such as sildenafil [14], and medications to ameliorate erectile dysfunction [32] and psoriasis [33]. The formalities involved in the procurement of prescription and non-prescription drugs are completely different. Hence, consumers should be enlightened about the importance and prudent use of prescription drugs. The online purchase of prescription drugs should be tightened. For instance, a robust system should be implemented where the patients are required to post an authentic prescription to the online pharmacy, specific and detailed patient information, and validation from the doctors prescribing the medication. In addition, it is recommended that prescription drugs sold online should either be strictly limited for legitimate consumers or to be sold only to doctors and pharmacists if they find that consumers are committing fraud or misusing the drugs [20].

2.1.7. Drug Prices

Drug prices were one of the factors contributing to excessive procurement and misuse of online drugs. For example, some online pharmacies offered a lower price per tablet if purchased in larger quantities. This encourages customers to buy and store more medicines, which may lead to drug overuse. Campbell et al. [14] mentioned that internet websites that provided prescription sildenafil, regardless of the requirement for a prescription, had a median per tablet price that was 22% higher than Viagra from area pharmacies [34].
In France, a study reported that the mean price of all medicines was higher than the price benchmarked by the country. However, some of the traditional systemic treatments were cheaper than prices in France [35]. Additionally, a 36% discount was also provided for bulk buying of traditional systemic and topical therapies [35]. These findings reinstate the need for consumers to be properly educated regarding drugs and prices. Consumers should understand that they might be substituting quality and authenticity for cheaper-priced drugs [36][37][38].

2.1.8. Marketing Strategies

Levaggi et al. [39] observed the statements that were often used by websites to promote their products. The strategies include a reduction in prices compared to “brick and mortar” pharmacies, free delivery, loyalty bonuses, and special discounts. Another study reported the competitiveness of marketing strategies, focusing on privacy protection and affordability [39]. The marketing of pharmaceutical products was based on special offers such as reduction in prices, which may encourage drug use without prescription or self-medication. This might increase the risk of drug misuse. Therefore, consumers should be aware of the tricks and strategies used by online pharmacies to increase patronage. It will help consumers to differentiate between the good online pharmacies and those that mainly prioritise their income [40].

2.1.9. Quality of Online Pharmacies

Some professional organisations have developed verification and accreditation systems for internet pharmacy to enhance patient safety [39][32]. These systems are designed to distinguish reliable websites from illegal operations [8][21]. The issue of low user safety is enhanced by poor process traceability, along with websites disappearing and a lack of transparency. More importantly, the extreme volatility of websites remains a serious concern from a public health perspective. According to the National Association of Boards of Pharmacy (NABP), 17% of the sampled websites were insecure [41]. Legal enforcement mechanisms empowered the Department of Justice and FDA to shut down websites that violated the Food, Drug, and Cosmetic Act 1938. The act includes the websites marketing the sale of narrow therapeutic index (NTI) drugs without a prescription. Moreover, the FDA should also support legislative action to prohibit online sales of pharmaceutical products by websites which are not accredited by the NABP Verified Internet Pharmacy Practice Site program [41].
The quality of online pharmacies and web vulnerability was investigated by Kuzma et al. [20]. A random sample of 60 online pharmacies was selected and the N-Stalker Web Application Security Scanner 2009 Free Edition 7.0 was used to execute the study objectives [42]. They found that most online pharmacies do not provide sufficient protection for their consumers, especially in cross-site scripting. The researchers suggested that online security could be improved by implementing a multi-phased approach. In addition, it will provide a better level of consumer protection and increased consumers’ trust and profitability. Another study revealed that two-thirds of rogue sites displayed stolen and false certifications seals including companies and intellectual property authority (CIPA), fake logos for organisations such as the Food and Drug Administration and Pharmaceutical Group of the European Union, and financial and shipping companies [1][15]. Some online pharmacies use pictures of doctors, professionals’ profiles, official trademarks, and all sorts of publically available information [3]. These practices make it difficult to distinguish between legitimate and illegitimate internet pharmacies [3].

2.1.10. Time of Existence of the Websites and Privacy Policy

The legality of online pharmacies can be determined based on the time of existence. Most of the online pharmacies operating non-prescription internet pharmacies are characterized by the limited availability of patients’ information and medication safety. They also operate illegally and provide medicines to consumers without a proper prescription. These online pharmacies disappear after a while [3][25].

2.2. Quality of Drugs Purchased

2.2.1. Drug Characteristics

Based on the drug characteristics, the majority of the purchased medications were prescription drugs. These drugs are classified under the law as protected drugs and can only be procured with valid prescriptions from physicians. However, some online pharmacies accept photocopied or faxed copies of prescriptions. Such practices may result in drug abuse since the same prescription can be used multiple times. In addition, prescription medicines sold by online pharmacies were used inappropriately because they tend to promote self-medication [2]. Another article that evaluated the purchase of isotretinoin without prescription detected that they were still advertising the drug for sale against the directive of the Medicines and Healthcare products Regulatory Agency [31]. Furthermore, the types of drugs purchased were brand-name drugs, and their quality was sometimes influenced by the manufacturing countries. For instance, some of the drugs made in Ethiopia, China, Thailand, Nigeria, India, Laos and Thailand failed the quality tests [3].

2.2.2. Drug Quality Characteristics

Both the internal and external parts of purchased drugs were physically evaluated to determine their quality. Firstly, in terms of packaging, more than half of the drugs were found to be labelled inappropriately. This includes a complete absence of labelling by the manufacturer or spelling errors in the name of the tablets. Specifically, 84% of the drugs purchased lacked leaflets or outer packaging and had damaged packaging [43]. Other issues included the absence of batch number, expiry date, and essential information such as side effects, contraindications, and drug interactions [44]. Another study found that none of the investigated drugs was packed inside a container nor packaged according to the European Council directive. This might increase the risk of consuming expired drugs, interaction with other medications and adverse reactions such as allergy. Nevertheless, some of the drugs had outer packaging but it is not a guarantee of authenticity. It is suggested that the products should be inspected according to good manufacturing practice. Such monitoring should be conducted either by the national or international competent authorities and regulatory agencies [37][45].

2.3. Characteristics of Consumers Who Patronise Online Pharmacies

A survey conducted in the United States on the use of erectile dysfunction medications showed that 12% of consumers purchased them on the internet, including undergraduate students [15]. Likewise, a study conducted in Argentina also reported a similar event, as 2.9% of the sales of phosphodiesterase 5 inhibitor (PDE5I) drugs for erectile dysfunction were sold to healthy young men. An observational study on the purchasing patterns of the same substances found that 11% of consumers reported the use of PDE5Is, while 32% of them obtained their drugs from sources outside the healthcare system. In contrast, a study showed no difference in age between consumers buying drugs online and those not engaging in such a practice. Additionally, no difference was observed in terms of student status [25]. However, the consumers on multiple medications were more likely to patronise online pharmacies compared to those with prescriptions [25].
One study tried to expose the “black box” of drug diversion. Drug diversion refers to the transfer of drugs from a legal to an illegal channel using several sources of information. the Delaware School Survey, several Miami street studies, and two qualitative studies [46]. They concluded that the internet is indeed a place for prescription drugs, with a large number of purchases probably at the wholesale level. Based on the results from a self-administered electronic questionnaire, higher-educated males and higher-income consumers were more likely to obtain medications online. This may be attributed to the fact that consumers tend to investigate the values and risks involved when buying medication online.

2.4. Consumer Safety

Consumer safety was discussed in most of the reviewed studies. Purchasing drugs online can be very risky and most consumers are unaware of the consequences. This is even more important when the online pharmacies are not recommended or illegal. Marketing strategies also contribute to the high demand for drugs. Apart from the advertisement of the advantages such as cheaper prices, other factors such as confidentiality and the desire to avoid physicians contribute to the increasing demand for online drugs. This is prevalent especially in countries other than the United States. In addition, the privacy issue has prompted consumers to believe that their data are protected. Hence, they rarely hesitate to reconsider the confidentiality issue. However, consumers are unaware that online pharmacies have a high potential to assist data-fishing or fraudulence when products are not delivered. These events will eventually lead to security issues.
