Online pharmacy

Online pharmacy is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Online pharmacy rather than just read about it. In short: An online pharmacy, internet pharmacy, or mail-order pharmacy is a pharmacy that operates over the Internet and sends orders to customers through mail, shipping companies, or online pharmacy web portal. Online pharmacies include: Legitimate Internet pharmacies in the same country as the person ordering.

Key takeaways

  • Online pharmacy belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Online pharmacy to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Online pharmacy from memory before moving on to harder problems.

Reference excerpt

An online pharmacy, internet pharmacy, or mail-order pharmacy is a pharmacy that operates over the Internet and sends orders to customers through mail, shipping companies, or online pharmacy web portal. Online pharmacies include:

Legitimate Internet pharmacies in the same country as the person ordering. Legitimate Internet pharmacies in a different country than the person ordering. This type of pharmacy is usually licensed by its home country and follows those regulations, not those of the international orders. Illegal or unethical internet pharmacies. The web page for an illegal pharmacy may contain lies about its home country, procedures, or certifications. The "pharmacy" may send outdated (expired shelf life) or counterfeit medications and may not follow standard procedural safeguards.

Home delivery Conventional brick and mortar pharmacies usually have controlled drug distribution systems from the manufacturer, sufficient validation, and follow good distribution practices. Home delivery of pharmaceuticals can be a desirable convenience, but sometimes it can lead to problems with uncontrolled distribution. The shipment of drugs through the mail and parcel post is sometimes a concern for temperature-sensitive pharmaceuticals. Uncontrolled shipping conditions can include high and low temperatures outside the listed storage conditions for a drug. For example, the US FDA found the temperature in a mailbox in the sun could reach 136 °F (58 °C) while the ambient air temperature was 101 °F (38 °C). Shipment by express mail and couriers reduces transit time and often involves delivery to the door, rather than a mailbox. The use of insulated shipping containers also helps control drug temperatures, reducing risks to drug safety and efficacy.

Risks and concerns Illegal or unethical pharmacies sometimes send outdated, substituted, or counterfeit medications to the person who ordered the drug instead of the real medication. Sometimes, an online pharmacy may not be located in a country that is claimed. For example, one study of drug shipments claiming to be from Canada revealed many of the drugs actually originated in several other countries and were often false medications. Minors can order controlled substances without adult supervision. Other concerns include potential lack of confidentiality, improper packaging, inability to check for drug interactions, and several other issues. The British Community Pharmacy Patient Safety Group was concerned that online pharmacies should implement "appropriate safeguards", "particularly when prescribing and dispensing medicines that are liable to abuse, misuse and overuse". The coroner in Leicester investigating a death found that a patient requesting drugs "has potential access to multiple online pharmacies", each of which "have no knowledge of what each other have been prescribing".

Discussion

Legitimate mail-order pharmacies are somewhat similar to community pharmacies; one primary difference is the method by which the medications are requested and received. Some customers consider this to be more convenient than traveling to a community drugstore, in the same way as ordering goods online rather than going to a shop. While many Internet pharmacies sell prescription drugs only with a prescription, some do not require a written prescription, as prescriptions may not be necessary in some countries. Some customers order drugs from such pharmacies to avoid the cost and inconvenience of visiting a doctor or to obtain medications their doctors are unwilling to prescribe. People living in the United States and other countries where prescription medications are costly may turn to online pharmacies to save money. Online pharmacies in the United States are required to be approved by the National Association of Boards of Pharmacy (NABP). Many of the reputable websites employ their in-house physicians to review the medication request and write a prescription accordingly. Some websites offer medications without a prescription or a doctor review. This practice has been criticized as potentially dangerous, especially by those who feel that only doctors can reliably assess contraindications, risk/benefit, and the suitability of a medication for a specific individual. Pharmacies offering medication without requiring a prescription, doctor review, or supervision are sometimes fraudulent and may supply counterfeit, ineffective, and possibly dangerous medicines.

International consumers

International consumers sometimes purchase drugs online from online pharmacies in their own countries or those located in other countries. A distinct increase in the frequency of buying medicines and health products online was measured since the breakout of the COVID-19 pandemic. Some of these pharmacies require prescriptions while others do not. Of those that do not require prescriptions, some ask the customer to fill in a health questionnaire with their order. Many drugs available at legitimate online pharmacies are produced by well-known manufacturers such as Pfizer, Wyeth, Roche, and generic drug makers Cipla and Ranbaxy of India and Teva Pharmaceutical Industries of Israel. However, it remains difficult for a patient to ascertain whether an online pharmacy is legitimate. Medicines obtained from rogue online pharmacies come with no guarantees concerning their identity, history, and source. A study in three cities in the Netherlands found that over 60% of the consumed sildenafil was obtained from illegal sources. Roger Bate from the American Enterprise Institute tested hundreds of prescription drug orders purchased over the Internet and discovered that properly credentialed online pharmacies, ones selling domestically and internationally, only sell lawfully-manufactured medicines.

Worked examples

Example 1 — a first encounter with Online pharmacy

Start with the simplest possible case. Write down what Online pharmacy claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Online pharmacy before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Online pharmacy ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Online pharmacy

In research
Online pharmacy appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Online pharmacy in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Online pharmacy is common in secondary-school and first-year university syllabi. It links to neighbouring topics Online pharmacies, Pharmaceuticals policy, so understanding it makes those chapters shorter.
In everyday life
Look for Online pharmacy outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
