6.1 NEED FOR THE STUDY
A fast dissolving system is defined as a dosage form for oral administration, which when placed in mouth,rapidly dispersed or dissolved and can be swallowed inthe form of liquid. Recently fast dissolving formulation ispopular as Novel Drug Delivery System because they are easy to administer andlead to better patient compliance. Pediatric and geriatric patients have difficulty in swallowing the conventionaldosage forms. Fast dissolving and fast dispersing drug delivery systems may offer a solution to these problems1,2,3.
Fast dissolving films have attained great importance in the pharmaceutical industry due to their unique properties and advantages4,5.This delivery system consists of a very thin oral strip, which is placed on the patient’s tongue or any oralmucosal tissue.They undergo disintegration in the salivary fluids of the oral cavity within a minute where they may release the active pharmaceutical ingredient6,7. Availability of larger surface area of the film leads to rapid disintegration in the oral cavity8,9.
The oral or buccal mucosa being highly vascularized, where the drugs can be absorbed directly and can enter the systemic circulation without undergoing hepatic first‐pass metabolism. This is one of the addedadvantageof orodispersible formulation as little quantity of the drug may get absorbed in the buccal cavity, can be exploited in preparing products withimproved oral bioavailability of molecules that undergo firstpass effect8,9.
Water is not required for administration of films and this leads to better acceptability amongst the dysphagic patients. The difficulty encountered in swallowing tablets or capsules is circumvented. The dosage form can be consumed at anyplace and anytime as per convenience oftheindividual8, 15.
The disadvantage of most Oral dispersible tablet is that they are fragile and brittle, which requires specialpackaging for protection during storage and transportation. Since the films are flexible they are not fragile. Hence, there is ease of transportation,consumer handling and storage8,9.
The Oral dispersible films are essentially prepared using water soluble and fast disintegrating polymers which also possess good film forming properties likehydroxypropyl methylcellulose ( HPMC),polyvinyl pyrolidone( PVP), polyethylene oxide (PEO) and hydroxypropylcellulose(HPC)4,10,11.
Vertigo, sometimes called as headrush, is a major symptom of a balance disorder. It is the sensation of spinning while the body is stationary with respect to the earth or surroundings. With the eyes shut, there will be a sensation that the body is in movement, called subjective vertigo; if the eyes are open, the surroundings will appear to move past the field of vision, called objective vertigo. The effects may be slight. It may cause nausea or, if severe, may give rise to difficulty with standing and walking. Vertigo is usually associated with a problem in the inner ear balance mechanisms (vestibular system), in the brain, or with the nerve connections between these two organs.
Most of the times vertigo is an acute symptom caused by the side effects of the drugs like, Methyldopa, Aspirin, Tetracycline, Streptomycin, Metronidazole, etc. it may be chronic in the disease like inner ear infection. Depending upon the clinical conditions a short term or long term treatment is essential to combate this symptom. Drugs like flunnarizine Cinnarizine, Betahistine hydrochloride, etc are being used in the treatment of vertigo
The objective of the present investigation is to develop formulations of Oro-dispersible filmof flunnarizine a drug of choice in the treatment of vertigo using appropriate grade of film forming polymer.
6.2 REVIEW OF LITERATURE:
A significant taste masking of verapamil and rapid disintegration of fast dissolving oral strips has been demonstrated. oral strips have been prepared by using different concentration of HPMC E6 and maltodextrin found to disintegrate in less than 30 seconds.They developed in vitro and in vivo evaluation of the films and confirmed their potential as an innovative dosage form to improve delivery of verapamil.Finally they concluded that bitter drugs such as verapamil can be successfully formulated and can be useful for geriatric, bedridden and noncooperative patients due to its ease of administration12.
A fast dissolving oral thin film containing dexamethasone and base materials, including microcrystalline cellulose, polyethylene glycol, hydroxypropylmethyl cellulose, polysorbate 80 and low-substituted hydroxypropyl cellulose have been formulated. The preparation revealed excellent uniformity and stability of dexamethasone and rapidly disintegrated in water. They observed no significant differences in pharmacokinetic parameters obtained from rats with oral administration of dexamethasone suspension and those with topical application of the film to the oral cavity. Hence fast-disintegrating oral film containing dexamethasone is considered to be potentially useful for cancer patients with disturbansce in eating and swallowing who receive radiotherapy and/or high- to moderate emetogenic anticancer drugs13.
Fast dissolving films of maltodextrins plasticized with 16–20% w/w glycerin were proved to be suitable to produce fast-dissolving films by differentmanufacturing processes, such as casting and solvent evaporation or hot-melt extrusion. Homogeneous films were achievable by loading a large amount of water insoluble powders, namely more than 15% w/w. When piroxicam was selected as a model drug, the film can contain more than 25 mg of active ingredient for a surface of 6 cm2. The loading of a drug as a powder in the film determined a decrease of the ductility, but the formulations maintained satisfactory flexibility and resistance to elongation for the production and packaging procedures.Compared to the hot-melt extrusion method, the casting methodappeared more reliable for the production of fast-dissolving films since the dosage forms exhibited the highest patients’ compliance and best performances in terms of in vitro and in vivo disintegration time. Furthermore, the films remarkably improve the dissolution of poorly soluble drugs, such as PRX which completely dissolved within 10 min independently of the drug loading14.
Rapidfilm, Oral dispersible tablets were compared with the films. Thetablets were rather big and bulky. So, the thin film may alleviate the fear of swallowing and the risk of choking commonly associated with a conventional tablet. Furthermore, the fast-dissolving action, primarily due to the wide surface area of the film, which wets quickly when exposed to the moist oral environment, can make Rapidfilm dissolving in small amounts of liquid: this can be beneficial for people suffering from reduced salivary secretion including chemotherapy- and/or radiotherapy-induced mucositis or sicca syndroma (Sjögren’s syndrome). In conclusion the Rapidfilm delivery system, by alleviating the administration by the end-user and by allowing patients to take their medication anytime and anyplace under all circumstances, can result in higher convenience for several applications15.
Fast-dissolving films of levocetirizine dihydrochloride can be considered suitable for clinical use in the treatment of allergic rhinitis and other conditions like allergies, where quick onset of action for a dosage form is desirable along with convenience of administration. The method of preparation is found to be simple and thus product cost is effective. In vivo study proved that fast-dissolving films of levocetirizinedi hydrochloride produced a faster onset of action as compared to conventional tablets16.
