The treatment of the posterior-segment ocular diseases, such as age-related eye diseases (AMD) or diabetic retinopathy (DR), present a challenge for ophthalmologists due to the complex anatomy and physiology of the eye. This specialized organ is composed of various static and dynamic barriers that restrict drug delivery into the target site of action. Despite numerous efforts, effective intraocular drug delivery remains unresolved and, therefore, it is highly desirable to improve the current treatments of diseases affecting the posterior cavity. This review article gives an overview of pharmacokinetic and biopharmaceutics aspects for the most commonly-used ocular administration routes (intravitreal, topical, systemic, and periocular), including information of the absorption, distribution, and elimination, as well as the benefits and limitations of each one. This article also encompasses different conventional and novel drug delivery systems designed and developed to improve drug pharmacokinetics intended for the posterior ocular segment treatment.

Experience Difficulty

Oral route is presently the gold standard in the pharmaceutical industry where it is regarded as the safest, most economical and most convenient method of drug delivery resulting in highest patient compliance. Over the past three decades, orally disintegrating tablets (FDTs) have gained considerable attention due to patient compliance. Usually, elderly people experience difficulty in swallowing the conventional dosage forms like tablets, capsules, solutions and suspensions because of tremors of extremities and dysphagia. In some cases such as motion sickness, sudden episodes of allergic attack or coughing, and an unavailability of water, swallowing conventional tablets may be difficult. One such problem can be solved in the novel drug delivery system by formulating “Fast dissolving tablets” (FDTs) which disintegrates or dissolves rapidly without water within few seconds in the mouth due to the action of superdisintegrant or maximizing pore structure in the formulation. The review describes the various formulation aspects, superdisintegrants employed and technologies developed for FDTs, along with various excipients, evaluation tests, marketed formulation and drugs used in this research area.

Disease Location

Psoriasis is one of the most stern and persistent autoimmune disease which affects about 1-3% population around the globe.  It influences an individual’s life quality by hindering them physically, socially and emotionally. The hyperproliferation of keratinocytes leads to excessive growth of skin cell which causes scaling and formation of plaques. Psoriasis can be mild moderate or severe depending on the percentage of skin area affected. Based on severity of the disease, location and the type of psoriasis, the treatment approaches can vary. Treatment regimens for psoriasis include topical therapies, systemic therapies and phototherapy. Conventional drug delivery approaches face various disadvantages therefore a need for better novel drug delivery system is required. The review paper focuses at providing a broad aspect of psoriasis and the novel treatment approaches which can help in tackling the disease.

Pharmaceutical technology has developed various newer modes of novel drug delivery aspects. Modifications in the previously existing drug delivery methods have led to various newly innovated technologies serving as a safe and effective means of improvement over the existing ones. Novasome technology is one of the new innovations of liposomes which have solved many of the problems related to liposomal drug delivery system. It offers a seven bilayer membrane which has the ability to incorporate both water soluble and insoluble drugs. It has an excellent entrapment efficiency which provides better medication. Formulation of novasomes is achieved in a high shear device. Due to its numerous advantages, novasomes have been used extensively in various fields like cosmetics, chemical, personal care, foods, pharmaceuticals and agrochemicals.
