FDA Approved Drugs: Changes to Approved Drugs

40
Post-approval, manufacturers may modify an approved new or generic drug product. Such modifications can encompass alterations in the Active Pharmaceutical Ingredient (API), manufacturing process, formulation, batch size, manufacturing site, and container closure system (FDA Guidance for Industry, April 2004). Often, a drug product may undergo multiple changes.These modifications require careful evaluation to determine their potential impact on the drug product's identity, strength, quality,...

Prescription, Nonprescription and Orphan Drugs

978
Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

Drug Administration and Therapy Phases: Overview

932
Drugs, the chemical agents used in diagnosing, treating, or preventing diseases, undergo a four-phase process of development: pharmaceutic, pharmacokinetics, pharmacodynamics, and therapeutic.
The pharmaceutical phase focuses on leveraging the physicochemical properties of the drug to design and manufacture an effective product. Variants include orally administered tablets or capsules, topical creams or ointments, and parenteral-delivery solutions or emulsions.
The pharmacokinetic phase...

Pharmacovigilance01:19

Pharmacovigilance

1.3K
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

300
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF01:24

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

277
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Area of Science:

  • Immunology
  • Neurology
  • Pharmacology

Background:

  • Multiple sclerosis (MS) is a chronic autoimmune disease affecting the central nervous system.
  • Sphingosine-1-phosphate (S1P) receptor modulators represent a therapeutic class for MS management.
  • Ponesimod targets the S1P receptor 1 (S1P1) selectively.

Purpose of the Study:

  • To summarize the development of ponesimod, an oral S1P1 receptor agonist.
  • To highlight key milestones leading to its US approval for multiple sclerosis.

Main Methods:

  • Review of ponesimod's development pathway.
  • Analysis of Phase III OPTIMUM trial data.
  • Summary of regulatory milestones in the US and EU.

Main Results:

  • Ponesimod demonstrated efficacy in the Phase III OPTIMUM trial for relapsing MS.
  • US FDA approval granted for the treatment of relapsing forms of MS.
  • Positive opinion received from the European Medicines Agency's Committee for Medicinal Products for Human Use (CHMP).

Conclusions:

  • Ponesimod's development culminated in US approval for relapsing MS.
  • The drug represents a new oral treatment option targeting S1P1 receptors.
  • Regulatory progress in the US and EU signifies its therapeutic potential.
