PHARMACEUTICAL COMPOSITION FOR TREATING URINARY SYSTEM

DISORDERS

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a pharmaceutical composition, and more particularly to a pharmaceutical composition includes a water-containing carrier carrying a carbon material, such that both water-containing carrier and carbon material constitute a pharmaceutically acceptable water-containing carrier carrying the carbon material for treating urinary system disorders.

2. Description of the Prior Art

Urinary tract infection (UTI) is inevitable in patients received prolonged indwelling urinary catheter and the use of catheters that can result in the introduction of bacteria into the urinary bladder. The indications of application of urinary catheterization include bladder outlet obstruction (BOO), either functional BOO, such as spinal cord injury or organic BOO, such as prostatic hypertrophy or urethral stricture, when accurate output monitoring is required, for selected operation in the perioperative period, to assist in healing of pressure ulcer. The indwelling catheter impairs host defences by providing access of microorganisms to the bladder. A variety of infecting organisms involved in catheter-related UTI. Escherichia coli is the most common, and other important organisms are Enterobacter spp., Pseudomonas aeruginosa, Klebsiella spp., Serratia spp., and Candida spp.

The presence of bacteriuria with i0 or more colony forming units per ml (CFUImI) is the simplest way of diagnosing the cystitis, Therefore, a large quantity of bacteria in urine indicates the occurrence of cystitis or pyelonephritis. From statistics of nosocomial infections occurred in intensive care units in Taiwan in 2007, it is found that the urinary tract infection occupies 37.5% of the total number of nosocomial infections and ranks No. I among all kinds of nosocomial infections in Taiwan, regardless of its occurrence in medical centers or regional hospitals. At present, the urinary system disease caused by bacterial infections in different age groups still rank the highest among urinary tract infections. In addition, an invasive treatment such as catheter insertion and cystoscopic examination is the most common treatment adopted by hospitals, and such treatment may be one of the main causes of exogenous infections, since bacteria are introduced into a bladder while there is a risk of causing an ascending bacterial infection that results in a bacterial cystitis, or even worse an acute cystitis or nephritis. In the most common bacterial cystitis, redness, swelling and vascular congestion occur at the position of the inflammation.

If cystitis occurs and causes discomfort and pain to the bladder and urgent micturition and related symptoms, and the cystitis is treated improperly, a severe infection may occur at the bladder or incur a failure of a patient's kidney that requires dialysis later, or will even incur a risk of fatal sepsis/urosepsis.

At present, the initiasl therapy of patients with catheter-acquired UTI is whether oral or parenteral antibiotics. Farenteral therapy is indicated in patients with severe toxic signs, including high fever, unstable vital signs oror patients who cant not tolerate oral administration. Intravesical instillation of antibiotics is an alternative approach in treatment of chronic inwelling catheter induced UTI, especially fungal urinary tract infection. The antimicrobial should be prescribed based on the urine culture results. A variecty of antimicrobial agents are used for treatment of catheter-related UTI, including penicillins, cephalosporines, fluoroquinolones, aminoglycosides etc. The techniques used for preventing a bacterial infection of an urinary tract include antibiotic methods, and application of coating medicine on the surface of a catheter, and using silver or silver plated catheters, etc. Recurrent UTI required multiple coursed of antibiotice therapy, thus increasing the probability of development of drug-resistant bacteria.

Although a large quantity of bacteria will be killed after taking the aforementioned medication treatments, the medication treatments also cause the production of lipopolysaccharides (LPS), and the LPS comes from the cell walls of bacteria and induces inflammatory reaction. Bladder cells to secrete cytokine including IL-i a 3, TNF-a, IL-6, IL-8 and IL-b inflammatory factors, and such inflammatory factors play an important role for the white blood cell accumulation of a bladder and cause the characteristics of inflammation including redness, swelling, heat and pain, or even internal bleeding in a severe inflammation. The aforementioned phenomenon usually occurs in patients wearing a catheter regularly since exogenous bacterial infections causing complicated infections such as chronic cystitis are inevitable, and some patients may be attacked by severe bacterial infections or even fatal sepsisturosepsis due to incomplete treatments. Furthermore, the treatments of cystitis or the techniques of preventing bacterial infections of urinary tracts seldom release the symptom continuously and may cause side effects in a long-term treatment and an application of the prevention techniques.

SUMMARY OF THE IN VENT/ON

Therefore, it is a primary objective of the invention to provide an effective cystitis treatment, as a cystitis treatment usually relies on an antibacterial medication for the treatment of an infection and fails to achieve the expected effect, and patients usually delay the time of treatments after they are infected by bacteria and a large quantity of bacteria have been reproduced, and visit a doctor until the symptoms including redness, swelling, heat and pain occur, which create a larger burden to the patient and incurs a higher risk of a drug resistance of bacteria, and these are the main causes for the difficulty of curing complicated bacterial infections or drug-resisting bacterial cystitis, and repairing the mucosa and lamina propria tissues of the bladder in order to prevent further bacterial invasions. Therefore, it is necessary to eliminate the bacteria of a cystitis and the toxic matters in the patient's body quickly, repair damaged mucosa and lamina propria tissues to prevent further invasions and reproductions of the bacteria, and promote the healing of wounds at the surface of the bladder before the infection or its recurrence can be controlled effectively, so as to release the symptoms of cystitis.

To achieve the foregoing objective, the present invention adopts the following technical measures and provides a pharmaceutical composition for treating urinary system disorders, and the pharmaceutical composition comprises a carbon material carried by a water-containing carrier and having a carbon content over 60 percentage by weight (wt%), such that both of the water-containing carrier and the carbon material constitute a pharmaceutically acceptable water-containing carrier carrying the carbon material, and the water-containing carrier carries a carbon material ranging from 0.1 mg/mI to 100 mg/mI per unit dose, and the carbon material has a diameter ranging from 2 nm to 2 mm and a carbon layer stack thickness (Lc) ranging from I nm to 1000 mm. The carbon material further comprises a metal particle selected from the collection of silver, platinum, palladium, gold, zinc and copper particles and any combination of the above, and the metal particle has a diameter falling within a range from 2 nm to 2 mm.

The present invention further provides a pharmaceutical composition for treating urinary system disorders, and the pharmaceutical composition comprises a carbon material or a carbon material combined with metal particles and contacted with a bladder and related tissues of the bladder in an animal body, wherein a carbon material composed of active carbon can be used for adsorbing bacteria, and the low-concentration ions of a uniformly distributed fine granular metal can be used for the disinfection effect and produce an effect of quickly adsorbing bacteria and the endotoxin which is the Iipopolysaccharides (LPS) produced by the cell walls of dead bacteria. Clinically, the endotoxin (LPS) will induce bladder cells to secrete cytokine including IL-I a I, TNF-a, IL-6, IL-8 and IL-b inflammatory factors, and such inflammatory factors play an important role of causing a white blood cell accumulation to the bladder, and characteristics of inflammation such as redness, swelling, heat and pain. The invention has the effects of reducing the endotoxins that causes the inflammation and reducing the symptoms of cystitis, while controlling infections effectively, preventing the recurrence of the cystitis, promoting the healing of wounds at the surface of the bladder, releasing the symptoms of cystitis, and treating and preventing cystitis, acute cystitis, chronic cystitis, hemorrhagic cystitis, bacterial cystitis, emphysematous cystitis, and interstitial cystitis, or curing patients with wounds in their bladder or urinary tract or patients with a urinary tract infection.

The invention can also achieve the effects of controlling infections, preventing the recurrence of cystitis, promoting the healing of wounds at the surface of a bladder, and releasing the symptoms of cystitis effectively.

MI-I (Normal): This group consists of normal rats without having the injection of an inflammation inducer or the induction of cystitis.

2. MI-2(LPS): This group consists of rats injected with an inflammation inducer to induce cystitis.

3. M1-3(LPS-ACF): This group consists of rats injected with an inflammation inducer to induce cystitis, and the water-containing carrier together with the carbon material is injected into a patient's bladder for the medical treatment.

Before experiments start, the rats are paralyzed by urethane first, and then the paralyzed rats are confirmed and fixed onto a soft board by tapes, and a polyethylene tube (PE-50) is used for the catheter insertion of the urinary tract. The following steps are carried out after the foregoing procedure completes.

Two rats are selected from the M1-2 (LPS) group and the M1-3 (LPS-ACF) group respectively and protamine sulfate (PS) is injected from the urinary tract into the bladder of the rats. The bladder mucosa of the bladder of the two rats from the M1-2 (LPS) group and the M1-3 (LPS-ACF) group are injured, and then an inflammation inducer is injected, wherein the injected inflammation inducer of this preferred embodiment of the present invention is an endotoxin such as the lipopolysaccharides (LPS) used for inducing the inflammation of the injured bladder and causing the rat bladder to have an inflammation. Normal saline is injected to rinse the bladder in 45 minutes after the protamine sulfate (PS) is injected, so as to control the range of injury and prevent the protamine sulfate (PS) from further harming lamina propria cells of the bladder.

After the bladder is rinsed, a quantity of 750 E.U. of the inflammation inducer which is the endotoxin is injected to induce the bladders of the rats to have the inflammation again. In the meantime, the inflammation inducer is injected once every half hour for a total of two times, and then normal saline is used for rinsing the bladder, and first urine samples of the three rats are collected respectively after an hour.

The pharmaceutical composition is injected into the M1-3 (LPS-ACF) group of rats, and the pharmaceutical composition containing the water-containing carrier together with the carbon material is added into a buffer solution, and whose concentration per unit dose is 4 mg/20 ml, and only the rats of the M1-2(LPS) group are injected with normal saline, and the injection takes place once every half an hour for a total of four injections. After an hour, second urine samples of the three rats are collected respectively. After a total of 24 hours, the bladders of the three rats are collected and weighted, and H & F stained pathogenic slides of the bladders of the rats from the three groups are prepared.
