8. / Brief Resume of the intended work:
6.1 Need of the study:
Systemic drug delivery through the sublingual route had emerged from the desire to provide immediate onset of pharmacological effect. Dysphagia (difficulty in swallowing) is a common problem of all age groups, especially elderly, children and patients who are mentally retarded, uncooperative, nauseated or on reduced liquid intake/diets have difficulties in swallowing these dosage forms.
Sublingual administration of the drug means placement of the drug under the tongue and drug reaches directly in to the blood stream through the ventral surface of the tongue and floor of the mouth. The drug solutes are rapidly absorbed into the reticulated vein which lies underneath the oral mucosa, and transported through the facial veins, internal jugular vein and braciocephalic vein and then drained in to systemic circulation1.
Hypertension is a disease that usually needs rapid action. Fast disintegrating tablets of anti-hypertensive drugs avoids hepatic metabolism due to pregastric absorption of drug, which reduces the dose and increase bioavailability. The medication as bitter pills has changed by use of flavours and sweeteners in fast disintegrating tablets of anti-hypertensive drugs and easy to administer for paediatric, geriatric and institutionalized patients. Fast disintegrating tablets of anti-hypertensive drugs results in quick dissolution and rapid absorption which provide rapid onset of action2.
Disintegrants are substances or mixture of substances added to the drug formulation that facilitate the breakup or disintegration of tablet or capsule content into smaller particles that dissolve more rapidly. Recently new materials termed as superdisintegrant have been developed to improve the disintegration processes. The disintegrants have the major function to affect the efficiency of the tablet binder and the physical forces that act under compression to form the tablet.3
In present study, attempt is made to prepare fast disintegrating sublingual tablets containing an anti-hypertensive drug along with various super disintegrants.
6.2 – Review of literature:
·  Vineet B, et al. have formulated and evaluated fast disintegrating sublingual tablets of Amlodipine Besylate. This is used in potential emergency treatment of angina and hypertension. The tablets were evaluated for weight variation, hardness, friability, wetting time, disintegrating time, dissolution study. The above study shows that dissolution rate of Amlodipine Besylate can be enhanced to a great extent by direct compression technique with the addition of super disintegrants4.
·  Rameshwari S, et al. have formulated and evaluated of Nifedipine sublingual tablet. Nifedipine for the potential emergency treatment of anginal pain and hypertension. In this study three different groups of formulation with variation on tablet excipients were prepared by direct compression method. In this study weight variation, hardness, friability, drug content, disintegration time, and dissolution rate are evaluated for each formulation and found satisfactory5.
·  Suresh VK, et al. have formulated of taste masked fast disintegrating Lisinopril tablets. Lisinopril used in the treatment of hypertension and congestive heart failure. In this study the influence of super disintegrating like cross povidone, croscaremellose sodium on disintegration time, wetting time and water absorption ratio were studied. In this study cross povidone showed better performance in disintegration time when compared to croscaremellose sodium. Here the acceptable taste can be made6.
·  Sindhu A, et al. have formulated and optimize sublingual tablets of Rabeprazole Sodium. It is a class of proton pump inhibitors used in the treatment of acid peptic disorder. In this they prepared the tablet by wet granulation method. The effect of formulation variable on wetting time and invitro dispersion time can be studied by applying optimization technique. Here super disintegrating like cross povidone, croscaremellose sodium, etc is used7.
·  Noushin B, et al. have formulated and optimize of Captopril sublingual tablet using D-optimal design. Captopril which is an effective drug in the treatment of hypertension. Here the tablets wereprepared by direct compression method using different ingredients such as poly vinyl pyrrolidone, starch1500, sodium starchglycolate, etc. According to this study PVP has a significant effect on tablet hardness; on the other hand, fast disintegrating Captopril sublingual tablets could be achieved by using higher amount of sodium starchglycolate as well as starch15008.
·  Narendra C, et al. have formulated and evaluated the sublingual tablet containing Terbutaline Sulphate. Here the formulation is prepared by wet granulation technique. In this study the effect of formulation variable on crushing strength, percentage friability and disintegrating time by applying the computer optimization technique. Disintegrating agent such as MCC, Crospovidone, etc. are used9.
·  Abeer MA, et al. have demonstrated the effect of pH on sublingual absorption of Oxycodone Hydrochloride. This study was to develop a sublingual spray drug delivery formulation of Oxycodone and evaluate the effect of formulation pH on sublingual absorption for acute pain. Here the rabbit is used as an animal model. The formulation pH appears to have no significant effect on sublingual absorption Oxycodone sprays formulation10.
