Небольшие количества витамина С имеются в продуктах животного происхождения (печень, мозг, мышцы). Для медицинских целей аскорбиновую кислоту получают синтетическим путем.
Аскорбиновая кислота играет важную роль в жизнедеятельности организма. Благодаря наличию в молекуле диенольной группы ( - СОН=СОН - ) она обладает сильно выраженными восстановительными свойствами. Участвует в регулировании окислительновосстановительных процессов углеводного обмена, свертываемости крови, регенерации тканей, образовании стероидных гормонов. Одной из важных физиологических функций аскорбиновой кислоты является ее участие в синтезе коллагена и проколлагена и нормализации проницаемости капилляров.
Организм человека не способен сам синтезировать витамин С; потребность в нем удовлетворяется витамином, вводимым с пищей. Недостаток или отсутствие его приводят к развитию гипо- или авитаминоза (цинги).
Кристаллическую аскорбиновую кислоту и содержащие ее препараты применяют в профилактических и лечебных целях во всех случаях, когда организм нуждается в дополнительном введении этого витамина: для профилактики и лечения цинги, при геморрагических диатезах, носовых, легочных, печеночных, маточных и других кровотечениях; в том числе вызванных лучевой болезнью, а также передозировкой антикоагулянтов, при инфекционных заболеваниях и интоксикациях, заболеваниях печени, нефропатии беременных, болезни Аддисона, вяло заживающих ранах и переломах костей, дистрофиях и других патологических процессах. Препарат назначают также при усиленном физическом труде, умственном напряжении, в период беременности и лактации.
Имеются данные о положительном влиянии аскорбиновой кислоты на липидный обмен при атеросклерозе.
Назначают аскорбиновую кислоту внутрь (после еды), внутримышечно или внутривенно.
При длительном применении больших доз аскорбиновой кислоты возможно угнетение функции инсулярного аппарата поджелудочной железы, поэтому в процессе лечения необходимо регулярно контролировать функциональную способность последней. В связи со стимулирующим влиянием аскорбиновой кислоты на образование кортикостероидных гормонов при лечении большими дозами необходимо следить за функцией почек и артериальным давлением.
