3 of 5 · Why the oral dose is larger

Listening

A tablet has to go through the gut wall and then straight through the liver before any of it reaches the rest of you. The liver takes a cut on the way past, and what is left is the bioavailable fraction.

YouSo an injection skips all of that?

It does. Straight into the blood, nothing taken off, which is why the oral dose of the same drug is the larger of the two.

How it works

  1. 1

    Pick a concept

    Open a concept in your module and start a 15-minute Lesson.

  2. 2

    Talk it through

    The tutor explains the concept from your study material. Answer, ask questions or interrupt, out loud.

  3. 3

    See what you covered

    When the Lesson ends, you get a written record of what you covered and what you struggled with.

Features

  • Taught from your pages

    The tutor teaches from your own study material and shows the passage it's explaining.

  • Diagrams when you ask

    Ask the tutor to draw a curve or a diagram, and it appears beside the conversation.

  • Interrupt any time

    Stop the tutor to ask a question or to hear something explained a different way.

  • Your audio isn't kept

    Lessons are saved as a written transcript. SymbioLearn doesn't store the recording.

Frequently asked questions

How long is a Lesson?

About 15 minutes, on one concept.

How many minutes do I get?

30 minutes free, once. Pro includes 300 minutes a month, and you can buy more: 60 minutes for $5.

Is my voice used to train AI?

No. Google's paid Gemini API terms say what you send isn't used to train its models, and SymbioLearn keeps a written transcript, not the recording.
