The treatment of onychomycosis is a challenging task because of unique barrier properties of the nail plate which hampers the passage of antifungal drugs in a concentration required to eradicate the deeply seated causative fungi in the nail bed. In present investigation, application of hydroxypropyl-β-cyclodextrin (HP-β-CD) was established as an effective and nail friendly transungual drug perm...

Several techniques are used to increase the aqueous solubilities of poorly water soluble drugs. Hydrotropic solubilization technique is one of them. In the present investigation hydrotropic solution of Urea (10M) has been used as a solubilizing agent to solubilize poorly water soluble drug. Fluvoxamine maleate shows maximum absorbance at 271 nm. Beer’s law was obeyed in the concentration range ...

Of all the pharmaceutical compounds, about 40% are considered poorly water soluble and hence, the development of efficacious formulation is being halted. It has been shown that a drug should have a minimum aqueous solubility of 1% to avoid bioavailability problems. During preformulation study, sufficient time should be invested in order to improve the solubility of these kinds of drug. At the v...

In the present investigation, mixed-solvency approach has been applied for the enhancement of aqueous solubility of a poorly water- soluble drug, zaltoprofen (selected as a model drug), by making blends (keeping total concentrations 40% w/v, constant) of selected water-soluble substances from among the hydrotropes (urea, sodium benzoate, sodium citrate, nicotinamide); water-soluble solids (PEG-...

The Hydrocortisone acetate (Figure 1) is a white crystalline powder; it melts at about 220°C with decomposition and is practically insoluble in water 1mg/100mL [2]. One method to overcome the poorly water solubility of HA is the use of cyclodextrins (CDs), which have been extensively studied [3]. CDs have been extensively used as complexing agents to improve the solubility of a variety of poorl...

Olmesartan medoxomil is a poor water soluble drug. There are numerous approaches available and reported in literature to enhance the solubility of poor water soluble drugs among which cyclodextrin complexation is predominant. β-cyclodextrin was used since this possess a special ability to complex with drugs enabling them to increase solubility, reduce bitterness, enhance stability and decrease ...
