Click in the Monte Carlo processing box to enable Monte Carlo simulation. Using the Program 43 Following the first line of each set which defines the set format the calcuyn data is entered. The first line of each set of drug data must contain, separated by tabspaces: The method has been applied to various scientific disciplines.

However, if drug 1 and drug 2 do not yield parallel lines in the median-effect plot, it is difficult to determine exclusivity. For two drug combinations, we may define from Eq. Oct 17th, Demo.

You can import a minimum of 1 and a maximum of 20 sets of data from a single text file. It is determined by the slope of the medianeffect plot. Computerized simulation of dose reduction index DRI in synergistic drug combinations.

## Computer Software

Three data files are installed with CalcuSyn in its Samples folder. Using the Program 19 CalcuSyn: Re-arranging equation 2 we get: As long as the m and Dm manuak for each single drug are available, the CI values for each data point of the nonconstant ratio design can still be calculated.

The data can be either tab-separated text. For mutually exclusive drugs, the combination index equation for the combination of n inhibitors 6, 8, 14 can be described by: The mass-action law is the basic law in Nature that forms the basis for the chemical equilibrium dynamics, physical absorption isotherm of Langmuir, biological receptor theory and enzyme kinetics.

Ara-C Fraction affected uM 0. Nonetheless, it goes without saying that you still require some specialized knowledge in order to get around CalcuSyn.

This appears to be a fairly valid assumption in most cases as although the distribution is truly log-normal the standard deviation is small and the distribution is similar to the normal distribution. Combination of more than Two Drugs For three drug combinations e.

### Biosoft: Software for Science

You will then be required to enter the dose data for all drugs in your combination. Using the Program 25 Step 4 – Enter the remaining points by pressing Enter or clicking on New to bring up the new points dialog. Highlighted paper with an editorial.

CalcuSyn 58 r value: The algebraic estimation algorithm makes the assumption that the uncertainty in the dose measurement is normally distributed.

In Synergism and antagonism in chemotherapy Chou, T. The median-effect dose or concentration. Text can be copied from the window and pasted into a spreadsheet or word processor for further formatting or processing. Graphs Graphs will show the certainty limits on the CI calcuayn.

Another term for potentiation.

### Analysis of drug interactions.

When the grid is used, data can be processed through wizards which make the software easily accessible to new users. Furthermore, the classic isobologram or the conservative isobologam cannot be constructed for calvusyn non-constant ratio design. Therefore, constant-ratio drug combination experiment design is much more efficient for data analysis than the nonconstant ratio drug combination experimental design.

The drug summary and data points are displayed for each component drug and for the combination drug. This is the first drug Data points entered: In this case, the component combinations can also be determined for their synergism or antagonism e.
