Antiasthma Drugs: Methylxanthines01:24

Antiasthma Drugs: Methylxanthines

349
Theophylline, a member of the methylxanthine class of bronchodilators, has long been used in asthma management. While its exact mechanism of action is not fully understood, it is believed to have multiple effects on various cellular processes.
Theophylline is thought to inhibit phosphodiesterase enzymes, increasing intracellular levels of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). This rise in cAMP and cGMP concentrations stimulates cardiac function,...

Cholinergic Antagonists: Therapeutic Uses

811
Antimuscarinic drugs have various therapeutic applications by inhibiting parasympathetic stimulation in different systems. Here are the key therapeutic uses of antimuscarinics:    
Respiratory Tract: Ipratropium, aclidinium, and tiotropium treat asthma, chronic bronchitis, and chronic obstructive pulmonary disease (COPD). They protect against bronchoconstriction caused by irritants like cigarette smoke, sulfur dioxide, and ozone. They also help reduce nasopharyngeal...

Hand hygiene

3.6K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents01:29

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

250
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 Glucocorticoids

190
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists01:23

Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists

247
Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...

Area of Science:

  • Dermatology
  • Pharmacology

Background:

  • Pentoxifylline (PTX) is a hemorheologic agent originally approved for intermittent claudication.
  • PTX exhibits anti-inflammatory and immunomodulatory properties, leading to its exploration in dermatology.

Purpose of the Study:

  • To review the diverse dermatological applications of pentoxifylline.
  • To highlight PTX as a potential therapeutic option for various skin conditions.

Main Methods:

  • A comprehensive literature search was performed on PubMed using "dermatology" and "pentoxifylline" from 1988 to 2022.
  • Eighty-one English-language articles were included after reviewing reference lists and excluding out-of-scope studies.

Main Results:

  • Pentoxifylline has demonstrated efficacy in treating a wide array of dermatological conditions.
  • These include peripheral vascular disease, vasculitis, chilblains, pigmented purpuric dermatosis, granuloma annulare, keloids, lichen sclerosus, scars, radiation fibrosis, vitiligo, alopecia areata, leishmaniasis, and leprosy.

Conclusions:

  • The use of pentoxifylline in dermatology is expanding, though larger studies and RCTs are limited.
  • Its favorable tolerability, cost-effectiveness, and minimal drug interactions support its use as a primary or adjunctive therapy.
