Combinational approach using solid dispersion and semi-solid matrix technology to enhance in vitro dissolution of telmisartan
Authors
Abstract:
The present investigation was focused to formulate semi-solid capsules (SSCs) of hydrophobic drug telmisartan (TLMS) by encapsulating semi-solid matrix of its solid dispersion (SD) in HPMC capsules. The combinational approach was used to reduce the lag time in drug release and improvise its dissolution. SDs of TLMS was prepared using hot fusion method by varying the combinations of Pluronic-F68, Gelucire 50/13 and Plasdone S630. A total of nine batches (SD1-SD9) were characterized for micromeritic properties, in vitro dissolution behavior and surface characterization. SD4 with 52.43% cumulative drug release (CDR) in phosphate buffer, pH 7.4, in 120 min, t50% 44.2 min and DE30min 96.76% was selected for the development of semi-solid capsules. Differential scanning calorimetry of SD4 revealed molecular dispersion of TLMS in Pluronic-F68. SD4 was formulated into SSCs using Gelucire 44/14 and PEG 400 as semi-solid components and PEG 6000 as a suspending agent to achieve reduction in lag time for effective drug dissolution. SSC6 showed maximum in vitro drug dissolution 97.49 % in phosphate buffer, pH 7.4 with in 20 min that was almost a three folds reduction in the time required to achieve similar dissolution by SD. Thus, SSCs present an excellent approach to enhance in vitro dissolution as well as to reduce the lag time of dissolution for poorly water soluble drugs especially to those therapeutic classes that are intended for faster onset of action. Developed approach based on HPMC capsules provided a better alternative to target delivery of telmisartan to the vegetarian population.

Solid dispersion refers to the dispersion of one or more active ingredients in an inert carrier in a solid state, frequently prepared by the melting method, solvent method, or fusion solvent method. The oral bioavailability of poorly water soluble drug remains as the most challenging aspects of drug development. Solid dispersion approach is to reduce particle size, therefore increases the disso...

Some drugs have low bioavailability due to their poor aqueous solubility and/or slowdissolution rate in biological fluids. Stiripentol (STP) is a novel anticonvulsant drug that isstructurally unrelated to the currently available antiepileptics. It has poor aqueous solubilityand its solubility has to be enhanced accordingly. Polyethyleneglycol 6000 (PEG-6000) iscommonly utilized as a hydrophilic...
