AN OVERVIEW ON ORAL THIN FILMS–METHODOLOGY, CHARACTERIZATION AND CURRENT APPROACH

The pharmaceutical sector is looking for new ways to deliver drugs, and one such way is through thin films. It has been said that thin films offer an alternative to traditional dosage forms. They offer rapid, local, or systemic effects and are a very flexible platform. Furthermore, patients with dysphagia, elderly, paediatrics, or bedridden patients, as well as those who have difficulty accessing water, can easily utilize these systems on their own. There are several ways to administer these drug delivery systems, including transdermally, ocularly, buccally, sublingually, and orally.One of the most creative and patient-focused novel drug delivery systems is Orodispersible Thin Films (OTF). Numerous pharmaceutical companies and academic experts worldwide are currently investigating the potential of these films for delivering drugs derived from both synthetic and natural sources. The beauty of this special drug delivery method is that, as we can see from the subjects' consumption of conventional dosage forms (tablets, capsules), they don't require water to be consumed. Furthermore, these delivery methods do a great job of encouraging patient compliance in general, especially in the case of both older and pediatric patients.This review shows a detailed review of oral thin film its applications and method of preparation; mainly focus of this research is thin film introduction to researchers and last 10 y of research on thin film with drugs and polymers used in research.

PULSATILE DRUG DELIVERY SYSTEMS THE NOVEL APPROACHPULSATILE DRUG DELIVERY SYSTEMS THE NOVEL APPROACH

Oral pulsatile drug delivery systems (PDDS) are intended to induce programmable lag phases before a quick and quantifiable, repeated, or prolonged medication release. As a result, they are gaining popularity due to their inherent suitability for achieving chronotherapeutic goals, which have just been highlighted concerning several prevalent chronic illnesses characterized by typical night or early-morning recurring symptoms (e. g. bronchial asthma, heart attack, rheumatoid arthritis, early-morningawakening). Furthermore, time-based colonic release is possible when pulsatile delivery devices are correctly modified to overcome unexpected gastric emptying and give delay periods that roughly match the small intestine transit time. Oral pulsatile administration is accomplished using several release platforms, including reservoir, capsular, and osmotic devices. The current review article addressed the topics that followed: the reason pulsatile drug delivery systems have been invented; diseases for which pulsatile release is necessary; classification, advantages and disadvantages; methods used in the current systems; the situation nowadays and its potential for the future; recent advancements, and especially, the previous five to ten years of research on pulsatile drug delivery conducted by researchers using a variety of drugs for a variety of diseases.
