(Box 122.2) The major limitation of intraocular antimicrobials is the short duration of action. In this study, we show how modulating the net charge of biopolymer-based drug carrier particles alters not only their mucoadhesivity but also other important properties, e.g., their stability, drug loading capacity and drug release profiles. Route of administration. Both of these orthodox methods of drug delivery face a number of barriers limiting their effectiveness in attaining therapeutic levels at the target site. Limited drugs are suitable to formulate for the ocular route. Oral route. Adverse Effects. In this guide, we summarise the most common routes used to administer drugs, the advantages and disadvantages of each drug route and examples of dosage forms that are used to deliver the active drug to the intended site of action in the body. To achieve the optimum drug delivery efficacy under varied ophthalmic diseases, the molecular weight (MW) and amount of HA should be selected rationally and applied to design diverse delivery systems. The ocular route of drug administration is generally associated to treat eye diseases; it is one of the most challenging drug delivery systems to the pharmaceutical scientist. Currently, approximately 90% of all ophthalmic drug formulations (e.g. Ocular inflammation results in breakdown of the blood-aqueous barrier, so systemic drugs will enter the eye. from goat cornea (100% after 6h). However, if the mucoadhesivity of a drug carrier is too high, this might limit the diffusive entry of molecules/drug carriers into the vitreous. Thus, administration routes like oral, systemic and topic generally presents low drug bioavailability due to the difficult to transpose ocular layers whereas routes like intravitreal and periocular, despite generating a great drug concentration inside the eye, are highly invasive and can cause serious side effects [151][152][153][154][155][156][157][158]. Keeping this in consideration, what are the 8 routes of drug administration? The results of ex vivo ocular diffusion of the FLZ nanoparticle gel Of the various routes used to administer drugs to the eye, the topical route is the most commonly used. Routes of Drug Administration: Route of administration refers to the starting point for the drug's introduction into the body up to the place where it acts upon the target organ or system.The route of administration for the drug depends on several factors like the nature of the drug, its pharmacokinetics, and the nature and urgency of the medical condition. o .time delay between administration of the drug and the onset of action. Describe advantages and disadvantages of the parenteral route of administration. 4. Route of administration - a way to get a drug into or onto the body.. What are the major routes of administration? Each route has specific purposes, advantages, and disadvantages. 1. It may be in the form of tablets, capsules, syrup, emulsions or powders. It is also suitable for all patients (child and elderly also). These advantages include safety, good patient compliance, ease of ingestion, pain avoidance, and versatility to accommodate various types of drugs (Sastry et al., 2000). Oral Route: Oral route is the most common route of drug administration. The ocular route has faster drug absorption and less systemic and visual side effects. In addition, this molecule has acted as solubilizer, emulsifier, stabilizer and P-glycoprotein (P-gp) inhibitor, that are important features to manufacture nanomedicines with suitable to overcome barriers and multidrug resistance (MDR) mechanisms. Oral route. Highlights: This study looks at the benefits of using the vaginal canal for drug administration. Placed in the eye (by the ocular route) or the ear (by the otic route) . Useful for local delivery of agents, particularly those which have toxic effects if administered systemically. The intramuscular route of drug administration is the method of administering drugs specifically to the depth of the bulk of the selected muscle. FLZ from sodium alginate gel containing nanoparticle formula F3 was 1.4-fold higher 3. We emphasize that, with all the three mixtures used for NP generation, the NP sizes obtained are suitable for intraocular delivery applications [37]. 4.
