Study Notes
Composition
- Intimate™ 5 mg tablets contain 5 mg tadalafil.
- Intimate™ 10 mg tablets contain 10 mg tadalafil.
- Intimate™ 20 mg tablets contain 20 mg tadalafil.
Pharmacology
- Tadalafil inhibits PDE5, increasing cGMP levels in the corpus cavernosum.
- This relaxation of smooth muscle allows blood flow into the penis for an erection.
- Tadalafil has no effect on blood flow without sexual stimulation.
Indication
- Tadalafil is used to treat erectile dysfunction (ED).
- It's also used to treat symptoms of benign prostatic hyperplasia (BPH).
- Combined treatment for both ED and BPH is available.
Dosage and Administration
For Use as Needed
- Starting dose is typically 10mg, taken before sexual activity.
- Dose may be adjusted to 20mg or 5mg based on individual response.
- Maximum frequency is once per day.
For Once Daily Use
- Starting dose is 2.5 mg taken daily, regardless of sexual activity schedule.
- Dose may be increased to 5mg based on individual response.
Renal Insufficiency
For Use as Needed
- Mild: No dose adjustment is needed.
- Moderate: Initial dose of 5 mg per day, maximum 10 mg every 48 hours.
- Severe: Maximum dose 5 mg every 72 hours.
For Once Daily Use
- Mild and Moderate: No adjustment required.
- Severe: Not recommended.
Hepatic Impairment
For Use as Needed
- Mild or Moderate: Maximum daily dose is 10 mg.
- Severe: Not recommended.
For Once Daily Use
- Mild to Moderate: Use with caution.
- Severe: Not recommended.
Geriatrics
- No dose adjustment is needed for patients over 65 years old.
Use with Food
- Tadalafil can be taken with or without food.
Contraindications
- Do not take tadalafil if you are using nitrates (e.g., nitroglycerin) as it can lower blood pressure dangerously.
Hypersensitivity Reactions
- Tadalafil can cause serious allergic reactions (Stevens-Johnson syndrome, exfoliative dermatitis).
- It is contraindicated for patients with known serious hypersensitivity to tadalafil.
Side Effects
- Possible side effects include: cardiovascular events, hypotension, hypertension, syncope, rash, urticaria, facial edema, Stevens-Johnson syndrome, exfoliative dermatitis, hyperhidrosis, abdominal pain, gastroesophageal reflux, migraine, transient global amnesia, epistaxis, blurred vision, nonarteritic anterior ischemic optic neuropathy, retinal vein occlusion, visual field defects, sudden decrease or loss of hearing.
Pregnancy and Lactation
- Tadalafil is not indicated for use in newborns, children, or women who are pregnant or breastfeeding.
Warnings and Precautions
- Monitor cardiovascular status of patients, especially those with pre-existing conditions.
- Be aware of potential drug interactions with nitrates, alpha-blockers, and antihypertensives, particularly for once-daily use.
- Be cautious in renal or hepatic impairment.
- Monitor for prolonged erections (priapism).
Overdosage
- Adverse events may resemble those observed at lower doses, and standard supportive measures should be taken.
Storage
- Store below 30°C, protected from light and moisture.
How Supplied
- Different strengths of tablets are available in various packaging sizes.
