Definitions
- therapy is usually administered by inhalation to deliver the drugs to the desired site of action.
- the doses are approximately 5% of the dose required with oral administration.
- the oral route may also be necessary. Difficulties associated with the use of inhalers may be overcome by the use of spacing devices to act as reservoirs for the drug to make it easier for the patient (especially a child) to inhale each dose.
- COPD chronic obstructive pulmonary disease
- bronchitis a range of disorders of progressive airflow limitation
- emphysema a range of disorders of progressive airflow limitation
- Drug treatment includes symptomatic and palliative therapy using bronchodilating agents.
- First-line drug therapy for the treatment of COPD consists of bronchodilating agents to alleviate bronchospasm and any reversible component of airway obstruction.
- the drug of first choice is a ⁇ 2 -selective agonist such as salbutamol or terbutaline given by inhalation.
- Salbutamol is rapidly absorbed from the gastro-intestinal tract. It is subject to first-pass metabolism in the liver and possibly the gut wall. The main metabolite is an inactive sulphate conjugate. It is rapidly excreted in the urine as metabolites and unchanged drug; there is some excretion in the faeces. It has been suggested that the majority of an inhaled dose is swallowed and absorbed from the gut (see Goodman & Gilman's The Pharmacological Basis of Therapeutics, Eighth Edition, Volume 1, Chap. 10 p204). The plasma half-life of salbutamol has been estimated to range from about 2 to as much as 7 hours.
- Cyclodextrin inclusion complexes may be prepared on the basis of liquid state, solid state or semi-solid state reactions between the components (J. Szejtli, Cyclodextrin Technology, Kluwer Academic Press). The first is accomplished by dissolving the cyclodextrin and guest in a suitable solvent or mixture of solvents and subsequently isolating the solid state complex by crystallisation, evaporation, spray drying or freeze drying. In the solid state method, the two components may be screened to uniform particle size and thoroughly mixed whereafter they are ground in a high energy mill with optional heating, screened and homogenized.
- the downfield shifts of the aromatic protons were greater than those of the aliphatic protons, suggesting that the aromatic ring of salbutamol interacts more strongly with the beta-cyclodextrin.
- the interior protons of the cyclodextrin molecule were shielded as a result of the anisotropy of the guest aromatic moiety.
- the highest shifts of beta-cyclodextrin protons occurred for a molar ratio of 1:1 (salbutamol: beta-cyclodextrin) indicating the probable stoichiometry of the complex.
- the selective ⁇ 2 -adrenergic agonist is preferably selected from the group consisting of salbutamol, metaproterenol, terbutaline, pirbuterol, formoterol, salmeterol, fenbuterol, orciprenaline, isoprenaline, hexoprenaline, reproterol, rimiterol, fenoterol, procaterol, mabuterol, bambuterol, bitolterol, broxaterol, carbuterol, clenbuterol, coterol, eformoterol, tretoquinol and tulobuterol and the pharmaceutically acceptable salts thereof, such as for example the sulphate, methanesulfonate, hydrochloride, dihydrochloride, acetate or monoacetate salts.
- an inclusion complex of salbutamol base and 2-hydroxypropyl-beta-cyclodextrin which has substantially the X-ray powder diffraction pattern of Figure 5 of the accompanying drawings or the Fourier Transform Infra-red spectrum of Figure 6 of the accompanying drawings.
- Figure 1 shows an X-ray powder diffraction pattern of a 1:1 kneaded complex of salbutamol base and randomly methylated- ⁇ - cyclodextrin obtained from Example 1 ;
- the crux of the invention is a pharmaceutical composition for oral mucosal delivery which comprises as an active ingredient an inclusion complex of (a) a selective ⁇ 2 -adrenergic agonist or a pharmaceutically acceptable salt thereof and (b) an unsubstituted beta- or gamma-cyclodextrin, together with a pharmaceutically acceptable carrier for oral mucosal delivery.
- cyclodextrins such as 2-hydroxypropylated or methylated or sulphoalkylated derivatives of beta-cyclodextrin are the preferred cyclodextrins of the invention.
- Gamma-cyclodextrin or 2- hydroxypropylated or methylated or sulphoalkylated derivatives of gamma- cyclodextrin may also be used in the same manner as the corresponding preferred beta-cyclodextrin derivatives.
- the degree of substitution of the cyclodextrin derivatives may vary between 1 to 20 substituents per cyclodextrin molecule but more preferably between 3 to 15 substituents per cyclodextrin molecule.
- a selective ⁇ 2 -adrenergic agonist through the mucosal tissue of the mouth avoids the problems associated with administration of these drugs by inhalation (i.e. only approximately 10% of the drug entering the lungs, difficulty with inhalation techniques resulting in therapeutic blood levels not being attained) and by oral administration (i.e. slower onset of action and extensive metabolism in the gastrointestinal tract).
- Penetration enhancers may be used to promote the passage of the drug active across the mucosal membranes.
- Typical permeation enhancers include fatty acids and their salts such as sodium caprate, sodium caprylate and sodium oleate, and bile salts such as sodium glycodeoxycholate, sodium glycocholate, sodium cholate and sodium taurodeoxycholate.
- Other penetration enhancers may include tensides or non-ionic surfactants such as polyethylene glycol 660 hydroxystearate or polyoxyethylene lauryl ethers, fusidates such as sodium taurodihydrofusidate, azone and chitosan.
- Example 1 Salbutamol base (2,00g) and methyl-beta-cyclodextrin (l l,57g) are mixed together in a mortar. Purified, deionized water (6ml) is added in aliquots with mixing to form a homogenous paste. The paste is dried in an oven at 40°C and atmospheric pressure. The dried complex is crushed with a pestle and passed through a 250 ⁇ m mesh sieve. At all processing stages, the compound is protected from light. The complex contains 14,1% mass/mass salbutamol base as determined by HPLC.
- Salbutamol base (2,00g) and 2-hydroxypropyl-beta-cyclodextrin (12,6g) are mixed together in a mortar.
- Purified, deionized water (10ml) is added in aliquots with mixing to form a homogenous paste. Continue grinding for 0,5 hours.
- the paste is dried in an oven at 40°C and 5 millibar.
- the dried complex is crushed with a pestle and passed through a 250 ⁇ m mesh sieve. At all processing stages, the compound is protected from light.
- the complex contains 13,24% mass/mass salbutamol base as determined by HPLC.
