Metformin has acid dissociation constant values (pK a) of 2.8 and 11.5, so it exists very largely as the hydrophilic cationic species at physiological pH values. The metformin pK a values make it a stronger base than most other basic medications with less than 0.01% nonionized in blood.
2. Alleviates Hunger. Metformin improves how well your cells respond to insulin. This helps regulate your blood sugar levels and manage spikes in insulin that can trigger hunger and food cravings.
Consistency and viscosity affect the adhesion and retention property of the gel, and are important in ensuring the gel is retained at the site of application and effective delivery of the drug. [3] The ingredients in topical gel formulation can be broadly categorized into four types: gelator, solvent, drug, and excipients.
The immobilized pH gradient is obtained by the continuous change in the ratio of Immobilines. An Immobiline is a weak acid or base defined by its pK value. [ 2 ] Immobilized pH gradients (IPG) are made by mixing two kinds of acrylamide mixture, one with Immobiline having acidic buffering property and other with basic buffering property. [ 3 ]
A container with cream. Topical cream formulation is an emulsion semisolid dosage form that is used for skin external application. Most of the topical cream formulations contain more than 20 per cent of water and volatiles and/or less than 50 per cent of hydrocarbons, waxes, or polyethylene glycols as the vehicle for external skin application.

PK/PD relationships can be described by simple equations such as linear model, Emax model or sigmoid Emax model. [5] However, if a delay is observed between the drug administration and the drug effect, a temporal dissociation needs to be taken into account and more complex models exist: [ 6 ] [ 7 ]
Depending on which type of metformin you take and your dose, however, you may take metformin more than once a day. Further, metformin comes in the form of immediate-release tablets, extended ...
Pioglitazone/metformin is indicated as an adjunct to diet and exercise: [medical citation needed] To improve glycemic control in patients with type 2 diabetes, or; For patients who are already treated with a separate combination of pioglitazone and metformin, For patients whose diabetes is not adequately controlled with metformin alone, or
