hydrophilic polymeric films for controlled release of hydrophilic drugs. The subject matter describes film-based polymeric pharmaceutical formulations capable of delivering hydrophilic drugs, their process of preparation and application. the formulations presented are made from natural hydrophilic polymers, for example chitosans, cellulose and hydrophilic derivatives; or synthetic, for example, derived from methacrylic acid, and may be used for topical application (skin and mucous membranes) of various hydrophilic drugs such as non-steroidal anti-inflammatory drugs, antimicrobials, antiglaucomates, sympathomimetics, cholinomimetics, immunosuppressants, adrenergic antagonists, cholinergic antagonists, keratolitic antagonists. , among others. |
