Medications delivered via the topical route offer a whole host of benefits. Here are five benefits of using a topical drug delivery system. 1. Alternative to Oral Administration. Many patients struggle with oral drug administration. Some risk vomiting, while others find swallowing pills a near-impossible task Historically, oral drug administration has been the predominant route for drug delivery. During the past two decades, numerous oral delivery systems have been developed to act as drug reservoirs from which the active substance can be released over a defined period of time at a predetermined and controlled rate Vesicular drug delivery system can be defined as highly ordered assemblies consisting of one or more concentric bilayers formed as a result of self-assembling of amphiphilic building blocks in presence of water. Vesicular drug delivery systems are particularly important for targeted delivery of drugs because of their ability to localize the activity of drug at the site or organ of action. Nanoemulsion is a promising alternative to increase drug delivery system penetration and targeting poorly soluble drugs, by increasing its absorption through the skin, better retention time of drug in the target area and eventually result in less side effects . The benefits of nanoemulsion with globules in nano-scale siz Abstract:Vesicular systems have many advantages like prolong the existence of the drug in the systemic circulation, minimizes the undesirable side-effects, reaches the active moieties to its target sites using the carriers. But the main drawback related to transdermal delivery is to cross stratum corneum which can be overcome by the utilization. In transdermal delivery, the CBD formulation is introduced into the blood stream through the skin at a steady rate. This form of delivery ensures that the drug is delivered to the body over a longer duration than oral doses. Transdermal CBD drug stays and acts in the body for a longer time than oral CBD because of this prolonged duration
