Antihistamínicos: Conceptos Fundamentales

Los antihistamínicos son fármacos esenciales que modulan las respuestas biológicas mediadas por histamina, una amina biógena crucial en procesos fisiológicos y patológicos. Su acción principal radica en el antagonismo competitivo de los receptores de histamina, atenuando síntomas alérgicos e inflamatorios.

Estructuras de cloruro de acetilo, bromuro de hexanoilo, yoduro de benzoílo y cloruro de p-clorobenzoílo.

La Histamina: Un Mediador Crucial

La histamina, sintetizada principalmente por mastocitos y basófilos, es clave en respuestas inmunes, inflamación y funciones gástricas/neuronales. Su liberación desencadena efectos fisiológicos y patológicos diversos. Su acción es mediada por receptores específicos.

Fórmula estructural de la (+)-Higrima, indicando estereoquímica (R).

Receptores de Histamina: H1 y H2

• H1: Alergias, inflamación, sistema nervioso central.

• H2: Secreción gástrica de ácido, ritmo cardíaco.

• Diferencias estructurales y de señalización cruciales.

• Blanco farmacológico para antihistamínicos específicos.

Mecanismo de Acción Antihistamínico

Los antihistamínicos actúan como antagonistas competitivos, bloqueando la unión de la histamina a sus receptores H1 o H2. Esto previene la cascada de señalización intracelular mediada por histamina, reduciendo así las respuestas alérgicas o la secreción ácida gástrica. Su especificidad por el subtipo de receptor determina su uso clínico.

Antihistamínicos H1: Acción y Efectos

Los antihistamínicos H1 antagonizan competitivamente los receptores H1, inhibiendo la vasodilatación, el aumento de la permeabilidad capilar y el prurito. Esto reduce la respuesta inflamatoria alérgica.

Reacción de haluro de acilo con benceno y halógeno

H1 de Primera Generación: Características

• Alta liposolubilidad: atraviesan barrera hematoencefálica.

• Causan sedación: efecto adverso principal.

• Antagonismo muscarínico: efectos anticolinérgicos.

• Ejemplos: difenhidramina, clorfeniramina.

H1 de Segunda Generación: Avances

• Mayor selectividad por receptores H1 periféricos.

• Mínima penetración en el SNC.

• Menor riesgo de sedación y efectos anticolinérgicos.

• Ejemplos: Loratadina, Cetirizina, Fexofenadina.

Indicaciones de los Antihistamínicos H1

Rinitis Alérgica

Eficaces para aliviar síntomas nasales como estornudos, rinorrea y prurito. Actúan bloqueando la histamina en los receptores H1.

Urticaria y Angioedema

Reducen el prurito y las ronchas cutáneas. Son el tratamiento de primera línea para estas afecciones alérgicas.

Conjuntivitis Alérgica

Alivian el picor, enrojecimiento y lagrimeo ocular. Pueden usarse por vía oral o en gotas oftálmicas tópicas.
