"Разрёшенный" means allowed for action or anything else that could be allowed to be done or used or prohibited to. "Подшилось" looks slightly unnatural. Past tenses of russian verbs indicate grammatical gender implicitly. In this case the neutral one is used. So it looks like some inanimate object has been filed to a folder or binder or has been hemstitched by someone but in impersonal (!) way. In case of masculine or feminine gender ("подшился" or "подшилась") it would mean that a person of corresponding gender has voluntarily got an antabuse implant against alcoholism or any other drugs abuse. The stem of this verb "шит(ь)" means to stitch. So in case of antabuse this verb accents the fact that something was sticthed under the skin (old fashion of administering such medications in Russia and CIS during 1990's).
