Drug discovery is the process by which drugs are discovered and/or designed. In the past most drugs have been discovered either by identifying the active ingredient from traditional remedies or by serendipitous discovery. The new approach has been to understand how disease and infection are controlled at the molecular and physiology level and to target specific entities based on this knowledge. New drugs begin in the laboratory with chemists, scientists and pharmacologists who identify cellular and genetic factors that play a role in ...

A Clinical Trial Protocol is a document that describes the objective(s), design, methodology, statistical considerations, and organization of a clinical trial. The protocol usually also gives the background and rationale for the trial, but these could be provided in other protocol referenced documents (such as an Investigator's Brochure). The protocol contains a study plan on which all clinical trials are based. The plan is designed to safeguard the health of the participants as well as answer specific research questions. The p ...

Drug development is considered a costly and intensive process. Of all compounds investigated for use in humans only a small fraction is eventually approved, and only after heavy investment in pre-clinical development,clinical trials, and safety monitoring to determine the safety and efficacy of a compound. Most clinical trials are randomized and controlled. The cost for a new drug (new chemical entity) is estimated to be about $1 billion US$. This figure is however hotly disputed.[3] Depending on a number of considerations, a company may app ...

A placebo, from the Latin for "I will please", is a medical treatment (operation, therapy, chemical solution, pill, etc.), which is administered as if it were a therapy, but which has no therapeutic value other than the placebo effect. Placebo - Early use of placebos. Originally, the placebo was a substance that a well-meaning doctor would give to a patient, telling him that it was a powerful drug (e.g., a painkiller), when in fact it was nothing more than a sugar pill. Thus, Hooper's medical dictionary of ...

Pharmaceutical company - The pharmaceutical industry is different. The pharmaceutical industry is different from most industries in that the products are usually not chosen by the consumers or paid for by the consumers. Physicians control the choice of many drugs through prescription writing. Private or public insurance often pays for most of the drugs. Moreover, insurance companies restrict the drugs that can be prescribed through the use of formularies. This along with the high margins for the industry make pharmaceutical marketing a complex discipline. ...

Some medications only show to have safety issues after they are marketed, as clinical trials are of a limited size, such as the 3,000 test subjects required by the FDA. Post-marketing surveillance ensures that after marketing the safety of a drug is monitored closely. In certain instances, its indication may need to be limited to particular patient groups, and in others the substance is withdrawn from the market completely. After the FDA (or other regulatory agency for drugs marketed outside the U.S.) approves a new drug, pharmaceutic ...

An antidepressant is a medication designed to treat or alleviate the symptoms of clinical depression. Some antidepressants, notably the tricyclics, are commonly used off-label in the treatment of neuropathic pain, whether or not the patient is depressed.

Many antidepressants also are used for the treatment of anxiety disorders, and tricyclic antidepressants are used in the treatment of chronic pain disorders such as chronic functional abdominal pain (CFAP), m ...

Cocaine - Appearance. Cocaine in its purest form is an off-white or pink chunky product. Cocaine appearing in powder form is a salt, typically cocaine hydrochloride (CAS 53-21-4). Cocaine is frequently adulterated or “cut” with various powdery fillers to increase its surface area; the substances most commonly used in this process are baking soda, sugars, such as lactose, inositol, and mannitol, and local anesthetics, such as lidocaine. Adulterated cocai ...

It was reported that about a quarter of patients who were administered a placebo, e.g. against back pain, reported a relief or diminution of pain. Remarkably, not only did the patients report improvement, but the improvements themselves were often objectively measurable, and the same improvements were typically not observed in patients who did not receive the placebo. Because of this effect, government regulatory agencies approve new drugs only after tests establish not only that patients respond to them, but also that their ef ...

Anemia will be diagnosed on the basis of suggestive symptoms, or found on the basis of routine testing, which includes a complete blood count (CBC). A sufficiently low hemoglobin or hematocrit value is diagnostic of anemia, and further studies will be undertaken to determine its cause. One of the first abnormal values to be noted on a CBC will be a high red blood cell distribution width (RDW), reflecting a varied population of red blood cells. A low MCV, MCH or MCHC, and the appearance of the RBCs on visual examination of a peripheral blood smear will ...

Randomized trials are employed to test efficacy while avoiding these factors. Trials may be open, blind or double-blind. Randomized controlled trial - Open trial. In an open trial, the researcher knows the full details of the treatment, and so does the patient. These trials are open to challenge for bias, and they do nothing to reduce the placebo effect. However, sometimes they are unavoidable, particularly in relation to surgical techniques, where it may not be possible or ethical to hide from the patient which treatment he or she received.
