La inhibición de la excreción de sebo por un bloqueador de H2
Lancet (London, England)
|June 30, 1979
Resumen
La cimetidina redujo parcialmente la excreción de sebo en pacientes con acné. El mecanismo exacto, ya sea el bloqueo de los receptores H2 o los efectos antiandrógenos, sigue siendo indeterminado.
Área de la Ciencia:
- Dermatología Dermatología dermatología.
- Farmacología Farmacología.
Sus antecedentes:
- El acné vulgaris es una afección cutánea común caracterizada por un exceso de producción de sebo.
- La excreción de sebo está influenciada por factores hormonales, incluidos los andrógenos.
- La cimetidina es un antagonista de los receptores H2 de la histamina con potenciales propiedades antiandrogénicas.
Objetivo del estudio:
- Para investigar el efecto de la cimetidina en la excreción de sebo en pacientes con acné.
- Explorar los posibles mecanismos subyacentes a la acción de la cimetidina en la producción de sebo.
Principales métodos:
- Administración de cimetidina en una dosis de 1g por vía oral al día a pacientes con acné.
- Evaluación de los cambios en las tasas de excreción de sebo después del tratamiento con cimetidina.
Principales resultados:
- La cimetidina demostró una inhibición parcial de la excreción de sebo en los pacientes con acné estudiados.
- El efecto observado sugiere un papel modulador de la cimetidina en la actividad de la glándula sebácea.
Conclusiones:
- La cimetidina exhibe un efecto inhibidor parcial sobre la excreción de sebo en el acné.
- Se requiere más investigación para aclarar si este efecto está mediado por el bloqueo de los receptores H2 o la actividad antiandrogénica.

Feedback Inhibition
Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!
Hormonal Regulation
Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.
Accessory Structures of the Skin: Sebaceous Glands
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

Pathophysiology of Peptic Ulcer Disease: Mucosal Defense Factors
Peptic ulcer disease, commonly called PUD, represents a multifaceted condition characterized by disruptions in the lining of the gastrointestinal (GI) tract. Central to the protection of the gastrointestinal lining is the mucosal-bicarbonate barrier. This physiological defense mechanism is a formidable shield against the corrosive effects of gastric acid and pepsin secretion in the stomach. Its role is pivotal in maintaining the structural integrity of the stomach's inner lining. Bicarbonate,...
Acid Suppressive Drugs for Peptic Ulcer Disease: Proton Pump Inhibitors
Peptic ulcers, often induced by H. pylori infections or NSAID usage, arise from disruptions in the delicate balance of gastric acid production. Peptic ulcers stem from heightened gastric acid levels due to H. pylori infections or NSAID use. The protective mucus layer diminishes in the presence of these factors, allowing gastric acid to erode the stomach lining and form ulcers.

Acid Suppressive Drugs for Peptic Ulcer Disease: Histamine H2-Receptor Antagonists
Histamine H2 receptors, which are intricately located on the basolateral membrane of parietal cells, play a crucial role in modulating gastric acid secretion. When released from enterochromaffin-like cells, histamine engages H2 receptors, initiating the cyclic AMP (cAMP) pathway. In this pathway, adenylyl cyclase converts ATP into cAMP, elevating intracellular cAMP levels. The activation of protein kinase A follows, stimulating the proton pump. This stimulation prompts the secretion of hydrogen...
