Levorotation carnitine pellet and method for preparing the same

Abstract

The invention provides a levocarnitine micro-pill which is prepared from levocarnitine and pharmaceutic adjuvant, characterized in that the pharmaceutic adjuvant is an excipient and a bonding agent; the content of the levocarnitine in the levocarnitine micro-pill is 10 to 90 weight percent; the excipient 20-80 weight percent and the bonding agent 1-5 weight percent. The levocarnitine micro-pill of the invention has the advantages of high dissolution rate, high bioavailability, easy preparation method and convenient and easy operation.

Description

Technical field:

[0001] The invention relates to the technical field of medicine and food, in particular to a pellet made of L-carnitine and a preparation method thereof. Background technique:

[0002] L-carnitine is an amino acid that promotes the conversion of fat into energy. No toxic side effects on the human body. Especially suitable for people to do aerobic exercise to reduce fat. The effect is more obvious. Different types of daily diets already contain 5-100 mg of L-carnitine. L-Carnitine is produced in the body's liver and kidneys and stored in the muscles, semen, brain and heart. L-Carnitine is indicated for a variety of problems related to heart health: preventing heart disease, improving heart function in people with congestive heart problems, minimizing its damage when following a heart attack, reducing angina pain, improving heart rhythm Uneven without affecting blood pressure, when increasing high-density cholesterol or good cholesterol, it reduces blood ...
