Científicos revelan la mejor forma de tragar pastillas

agua de la píldora del hombre

Los investigadores descubrieron que consumir pastillas mientras se descansaba sobre el lado derecho era por mucho lo mejor, ya que permitía que las pastillas entraran en la parte más profunda del estómago y se disolvieran 2,3 veces más rápido que incluso en una postura erguida.

Según un estudio reciente de Johns Hopkins, la forma en que traga las píldoras puede afectar la rapidez con que su cuerpo absorbe el medicamento.

Probablemente no tenga en cuenta la postura de su cuerpo mientras toma pastillas cuando tiene dolor de cabeza. Sin embargo, una investigación reciente de la Universidad Johns Hopkins descubrió que su postura puede afectar significativamente la rapidez con que su cuerpo absorbe el medicamento, hasta una hora más.

Las conclusiones se basan en lo que se cree que es el primer modelo que reproduce cómo se disuelve un fármaco en el estómago humano.

“Nos sorprendió mucho que la postura tuviera un efecto tan inmenso en la velocidad de disolución de una píldora”, dijo el autor principal Rajat Mittal, ingeniero de Johns Hopkins y experto en dinámica de fluidos. “Nunca pensé si lo estaba haciendo bien o mal, pero ahora definitivamente lo pensaré cada vez que tome una píldora”.

Pill Posture

The majority of pills don’t start working until the stomach passes its contents into the intestine. As a result, the closer a pill falls to the antrum, the quicker it begins to break down and unload its contents into the duodenum, the first part of the small intestine. If you’re aiming a pill for this part of the stomach, your posture is crucial in order to take use of gravity as well as the inherent asymmetry of the stomach.

Four postures were tested by the team. Taking tablets while resting on the right side was by far the most effective, sending pills into the deepest part of the stomach and achieving a dissolution rate that was 2.3 times quicker than even an upright posture. The worst was lying on the left side. The team was astounded to discover that if a tablet dissolves in 10 minutes on the right side, it may take up to 23 minutes in an upright posture and over 100 minutes while laying on the left side.

“For elderly, sedentary or bedridden people, whether they’re turning to left or to the right can have a huge impact,” Mittal said.

Standing upright was a decent second choice, essentially tied in effectiveness with lying straight back.

The team also considered stomachs that aren’t functioning at full strength due to gastroparesis caused by diseases such as diabetes and Parkinson’s Syndrome meant for pill dissolution. Even a small change in the conditions of the stomach can lead to significant differences in the outcome of an oral drug, said lead author Jae Ho “Mike” Lee, a former postdoctoral researcher at Johns Hopkins.

The impact of stomach disease on drug dissolution was similar to that of posture—which underscores how significant a difference posture makes.

“Posture itself has such a huge impact it, it’s equivalent to somebody’s stomach having a very significant dysfunction as far as pill dissolution is concerned,” Mittal said.

Future work will attempt to predict how the changes in the biomechanics of the stomach affect how the body absorbs drugs, how food is processed in the stomach, and the effect of posture and gastroparesis on food digestion.
