Slow-K (Potassium Chloride) - Summary

 
 



SLOW-K SUMMARY

Slow-K®

Slow-K, potassium chloride extended-release tablets USP, is a sugar-coated (not enteric-coated) tablet for oral administration, containing 600 mg of potassium chloride (equivalent to 8 mEq) in a wax matrix. This formulation is intended to provide an extended-release of potassium from the matrix to minimize the likelihood of producing high, localized concentrations of potassium within the gastrointestinal tract. Slow-K is an electrolyte replenisher.

BECAUSE OF REPORTS OF INTESTINAL AND GASTRIC ULCERATION AND BLEEDING WITH EXTENDED-RELEASE POTASSIUM CHLORIDE PREPARATIONS, THESE DRUGS SHOULD BE RESERVED FOR THOSE PATIENTS WHO CANNOT TOLERATE OR REFUSE TO TAKE LIQUID OR EFFERVESCENT POTASSIUM PREPARATIONS OR FOR PATIENTS IN WHOM THERE IS A PROBLEM OF COMPLIANCE WITH THESE PREPARATIONS.

  1. For therapeutic use in patients with hypokalemia, with or without metabolic alkalosis; in digitalis intoxication; and in patients with hypokalemic familial periodic paralysis. If hypokalemia is the result of diuretic therapy, consideration should be given to the use of a lower dose of diuretic, which may be sufficient without leading to hypokalemia.
  2. For the prevention of hypokalemia in patients who would be at particular risk if hypokalemia were to develop, e.g., digitalized patients or patients with significant cardiac arrhythmias.

The use of potassium salts in patients receiving diuretics for uncomplicated essential hypertension is often unnecessary when such patients have a normal dietary pattern and when low doses of the diuretic are used. Serum potassium should be checked periodically, however, and if hypokalemia occurs, dietary supplementation with potassium-containing foods may be adequate to control milder cases. In more severe cases, and if dose adjustment of the diuretic is ineffective or unwarranted, supplementation with potassium salts may be indicated.

Clinical Trials Related to Slow-K (Potassium)

Pharmacodynamic Trial, of Slow Release ASA, in Platelet Functionalism, a Long Term Treatment Period [Completed]
Evaluation of the pharmacodynamic profile (antiaggregant profile, balance of prostanoids and nitric oxid) of a ASA-SR (slow-release)formulation in comparison with a ASA NR (normal release), 150 mg, during 12 months of treatment.

Short Term Hemodynamic Effects of Controlled Slow Breathing With Biofeedback in Patients With Heart Failure [Recruiting]
Heart failure is associated with faster breathing, which has a negative impact on the functioning of the heart. This leads to fatigue, shortness of breath, and exercise intolerance. It has been shown that when slow breathing technique was taught to patients with heart failure, they had a reduction in their sensation of shortness of breath and an improvement in their exercise performance.

The study will compare the short-term effects of controlled slow breathing with biofeedback in normal healthy subjects, acute heart failure, and chronic stable heart failure. The purpose is to see if there is any change in the objective measurements of heart function while breathing at normal rates compared to a controlled slower rate.

Randomized Controlled Trial Comparing Slow-Freezing to Vitrification of Oocytes [Recruiting]
Preservation of fertility is limited. Current methods include embryo cryopreservation and while still experimental, ovarian cryopreservation. In single women who are at risk for infertility secondary to cancer or couples who have ethical reasons to avoid embryo cryopreservation, oocyte cryopreservation is an alternative Purpose of study is to compare slow freeze to vitrification of human oocytes. Successful cryopreservation and subsequent thawing programs are characterized by avoiding ice crystal formation. Vitrification, newer alternative to slow freeze method, process by which water is prevented from forming ice.

Our hypothesis is that higher survival rate per oocyte is to be expected in the vitrification group.

Effects of Intra-Uterine Slow-Release Insemination on Pregnancy Rate in Women Designated for Artificial Insemination [Recruiting]
A couple that does not achieve pregnancy though regular attempts for a year are defined infertile couple. This condition is caused by faulty functioning of the reproduction system of the husband or wife or both. If there are no organic defects and there is no definite injury to the reproductive system (ova or spermatozoa), the specialist doctor generally decides to put the couple into a fertility treatment program. Artificial insemination is one of the important ways of achieving pregnancy.

Three common methods of artificial insemination:

1. Placement of a diaphragm that contains raw spermatozoa or isolated improved spermatozoa in an appropriate liquid solution (Cup insemination, CI) upon the cervix.

2. Spermatozoa injection (after improvement) through the vagina to the cervix (Intra-Cervical Insemination, ICI).

3. Spermatozoa injection (after improvement) directly into the uterus (IUI-Intra-Uterine Insemination).

The EVIE - Slow Release Insemination method:

The slow release insemination is utilizing a Grasby type MS16 pump for 3 hours. The release rate for motile spermatozoa is 50X103 per minute.

Advantages:

- Very close approximation of the natural procedure in which the spermatozoa arrive to

the fertilization site over a long period.

- An extended "window of opportunities" for meeting between the ovum and spermatozoa will

be longer.

- There is no loss of spermatozoa due to leaking as sometimes happens with single-time

injection practiced in the IUI method.

Primary Endpoint:

Accumulation of 50 cycles of SRI- slow release insemination (study group) in addition to 50 cycles of regular IUI (control group). Two weeks after insemination Beta hCG test

Secondary Endpoints:

Four weeks after insemination - US Viability scan

Procedure:

Subjects will be women with fertility difficulties who are designated for IUI treatment. 100 insemination cycles will be conducted. (50 regular IUI and 50 EVIE-SRI). Subjects that were treated with the IUI method and who does not become pregnant will then be treated with the EVIE-Slow Release method and vice versa.

Efficacy of Slow Release Clotrimazole Varnish Treating Denture Stomatitis Comparing to Traditional Treatment of Troches [Not yet recruiting]
Background: Oral candidiasis is most frequently found among the elderly .It is accompanied with oral pain, irritation, burning sensation. In addition, the altered taste sensation may cause nutrition compromise, which may affect ones diet. Management of superficial oral Candida is usually achieved by treatment with clotrimazole, a fungi static drug which is given five times per day with instruction to slowly suck on it with out the dentures.

Working hypothesis and aims: Management of oral candidiasis is feasible. The major disadvantage of the mode of action now days is the substantively of the drug in the oral cavity and patient compliance. A sustained release varnish which is easily applied on the dentures, which also release the anti fungal drug for at least a day, may overcome some of the pit falls of the treatment applied today.

Based on our past experience, in developing local sustained release varnishes for dental use, we anticipate that we can also formulate a special anti fungal sustained release varnish which will fit the special and unique needs of the elderly population.

Methods: Sustained release varnish will be developed in our laboratory. The kinetics of release (using HPLC) and antifungal activity (Bioassays) will be examined in vitro. The formulation showing the optimal results will be tested on human subjects with oral candidiasis. The efficacy of the varnish will be examined clinically (reduction in symptoms), microbiology (reduction of oral fungal), pharmaceutically (release kinetics in vivo).

Expected results: The clinical out come of one time varnish application will be improved compared to the five times application of lozenges (used today). The severity of the disease should decrease and the healing period should be shorten drastically.

Importance: This is a novel pharmaceutical development of a local application of a dental varnish designed specially to the elderly population
