Definitions
- the present invention is directed to the treatment of bronchospastic airway diseases, especially reversible airway hyperreactivity, with a calcium channel blocker. More particularly, the invention is concerned with such treatment using the calcium channel blocker gallopamil.
- the compound gallopamil is a known calcium channel blocker. Like other calcium channel blockers such as nifedipine, diltiazim, and verapamil, gallopamil is used in cardiovascular therapy. Verapamil, diltiazim and nifedipine have been tested for possible use as active therapeutic agents in treating reversible airway hyperreactivity. However, the dosages necessary to obtain the desired airway hyperreactivity reduction have resulted in undesirable side effects such as broncho spasm. Also, the dosages have been as high or higher than the dosages used in cardiovascular therapy.
- the present invention is directed to a method for treating a bronchospastic disease characterized by airway hyperreactivity comprising administering to a subject an amount of gallopamil sufficient to reduce airway hyperreactivity, particularly via a pulmonary route.
- a second aspect of the invention involves a composition for treating a bronchospastic disease characterized by airway hyperreactivity, comprising an amount of gallopamil effective to reduce airway hyperreactivity and a pharmaceutically acceptable carrier, adjuvant or excipient therefor, especially in a form suitable for aerosol administration.
- the present invention concerns treatment of bronchospastic airway diseases, especially reversible airway hyperreactivity, by administration of the calcium channel blocker gallopamil (5- [ [2-(3,4-dimethoxyphenyl) ethyl]methylamino]-2-isopropyl-2-[3,4,5-trimethoxy- phenyljpentanonitrile hydrochloride) .
- gallopamil is intended to cover useful derivatives such as other pharmaceutically acceptable salts, non-salt forms, etc.
- reversible airway hyperreactivity refers to conditions such as allergen and exercise-induced asthma, etc., which result in reversible blockage of the air. passages. So-called irreversible airway conditions such as emphysema also involve reversible aspects. It is expected that the present invention will be most useful in treatment of chronic conditions.
- the gallopamil be administered in a pulmonary fashion, i.e., directly to the lungs in the form of an aerosol.
- aerosol administration can be in the form of a nebulized saline solution.
- the solution can include about -1% by weight gallopamil in 0.4% saline. Solubility of gallopamil in the solution is improved by addition of solubilizers such as ethanol and propylene glycol, both in amounts of about 4% by weight, for example. pH adjustment should be accomplished with sodium bicarbonate. .
- the gallopamil could be dispersed in freon and administered through a metered dose inhaler.
- a metered dose inhaler with an inhaling device such as that disclosed in Sackner et al. U.S. Patent 4,484,577, the disclosure of which is incorporated herein by reference.
- Oral administration in the form of tablets or capsules is possible, but may be disadvantageous because higher dosages are required, possibly leading to undesired cardiovascular effects.
- Parenteral and topical administration are also possible, although not preferred because of inconvenience and higher required dosage. Parenteral administration likely would be most useful in emergency situations, but it is contemplated that the present invention will be most useful in a preventative manner or for relief via self-administration.
- the gallopamil When the gallopamil is delivered via a nebulized saline solution, enough solution should be used to provide a gallopamil dose of about 1-20 mg, preferably 1-10 mg. This dosage can be repeated up to three or four times per day. When a metered dose inhaler is used in place of the nebulization, the dose of gallopamil may be reduced to about one tenth of the nebulized dose, preferably about 0.1-1 mg of gallopamil.
- a nebulized aerosol composition can be made using 0.4% saline' as the carrier for gallopamil to be delivered in a nebulized manner.
- Suitable solubilizers and other presently known components for aerosol compositions can be used if necessary or desired.
- Carrier gases presently known for use in metered dose inhalers, such as freon, are suitable for administering gallopamil from a metered dose inhaler.
- PD__ methacholine
- FEV.. forced expired volume in one second
- PD___ methacholine
- Administration of nebulized gallopamil (3 ml of a solution containing amounts of gallopamil varying from 1-20 mg, 4% ethanol and 4% propylene glycol in sterile saline, pH adjusted to 6 with sodium bicarbonate) increases the PD u for methacholine by 2-3 fold, thus showing significant reduction in airway hyperreactivity.
- bronchospasms are not present.
- Approximately 10 times as much verapamil does not produce as large a D 2 n increase, and bronchospasm results from higher dosages.
