Slide 1: Title Slide

Title: Metformin: A Comprehensive Overview

Presenter: [Your Name]

Course: Pharmacology

Date: November 30, 2023

Slide 2: Introduction

• Metformin is an oral biguanide medication used to treat type 2 diabetes.
• It is the first-line medication for type 2 diabetes in most guidelines.
• Metformin works by lowering blood glucose levels by reducing glucose production in the liver and increasing insulin sensitivity in the muscles and liver.

Slide 3: Pharmacodynamics

• Metformin’s primary mechanism of action is to decrease hepatic glucose production.
• It also increases insulin sensitivity in the muscles and liver, enhancing glucose uptake and utilization.
• Metformin does not stimulate insulin secretion from the pancreas.

Slide 4: Pharmacokinetics

• Metformin is rapidly absorbed from the gastrointestinal tract.
• Peak plasma concentrations are reached within 2-3 hours.
• Metformin is not extensively metabolized and is primarily excreted unchanged in the urine.
• The half-life of metformin is approximately 6 hours.

Slide 5: Drug Information

• Generic name: Metformin hydrochloride
• Brand names: Glucophage, Glumetza, Fortamet, Riomet
• Dosage forms: Tablets, capsules, extended-release tablets
• Pregnancy category: B

Slide 6: Administration

• Metformin is typically taken twice or three times a day with meals.
• Extended-release tablets can be taken once a day.
• Metformin should be taken with food to reduce gastrointestinal side effects.

Slide 7: Dosage

• The usual starting dose of metformin is 500 mg twice a day.
• The dose can be gradually increased to a maximum of 2,000 mg twice a day.
• Dosage adjustments may be necessary based on individual factors, such as renal function and glucose control.

Slide 8: Contraindications

• Metformin is contraindicated in patients with hypersensitivity to metformin or lactic acidosis.
• It is also contraindicated in patients with severe renal impairment (creatinine clearance < 30 mL/min).

Slide 9: Side Effects

• The most common side effects of metformin are gastrointestinal, such as diarrhea, nausea, and vomiting.
• These side effects are usually mild and transient.
• Metformin can also cause a rare but serious condition called lactic acidosis.

Slide 10: Adverse Reactions and Warnings

• Metformin can cause lactic acidosis, a serious but rare condition characterized by a buildup of lactic acid in the blood.
• Lactic acidosis is more likely to occur in patients with impaired renal function, dehydration, or liver disease.
• Symptoms of lactic acidosis include fatigue, muscle aches, shortness of breath, and abdominal pain.

Nursing Considerations

• Assess renal function before initiating metformin therapy and periodically thereafter.
• Encourage patients to drink plenty of fluids, especially during exercise or illness.
• Monitor patients for signs and symptoms of lactic acidosis.
• Educate patients about the potential for lactic acidosis and the importance of seeking medical attention if they experience any of the associated symptoms.
