Description
Overview of the medicine
Durevolis 10 mg Tablet contains Tadalafil, a phosphodiesterase-5 (PDE5) inhibitor, primarily used to treat erectile dysfunction (ED) and symptoms of benign prostatic hyperplasia (BPH). It helps increase blood flow to the penis to achieve and maintain an erection during sexual stimulation, and relaxes smooth muscle in the prostate and bladder to improve urinary flow in BPH.
Uses & Indications
Dosage
Adults
For ED: The recommended starting dose is 10 mg taken as needed, approximately 30 minutes prior to sexual activity. The dose may be increased to 20 mg or decreased to 5 mg based on individual efficacy and tolerability. Maximum dosing frequency is once per day. For BPH: 5 mg once daily at approximately the same time each day.
Elderly
No dosage adjustment is required for elderly patients.
Renal_impairment
Mild to moderate renal impairment: No dosage adjustment. Severe renal impairment: A maximum dose of 10 mg every 48 hours for ED, and not recommended for BPH.
How to Take
Take Durevolis 10 mg Tablet orally, with or without food. It can be taken at any time of day.
Mechanism of Action
Tadalafil selectively inhibits cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). When sexual stimulation causes local release of nitric oxide, PDE5 inhibition by tadalafil increases cGMP levels in the corpus cavernosum, leading to smooth muscle relaxation and inflow of blood into the penis, resulting in an erection. For BPH, it relaxes smooth muscle cells in the prostate and bladder, improving urinary flow.
Pharmacokinetics
Onset
Erectile effects typically observed within 30-60 minutes.
Excretion
Excreted predominantly as metabolites in the feces (approximately 61% of the dose) and, to a lesser extent, in the urine (approximately 36% of the dose).
Half life
Approximately 17.5 hours.
Absorption
Rapidly absorbed after oral administration. Mean maximum observed plasma concentration (Cmax) is achieved between 0.5 and 6 hours.
Metabolism
Primarily metabolized by cytochrome P450 (CYP) 3A4 to a catechol metabolite, which is glucuronidated. The major circulating metabolite is methylcatechol glucuronide.
Side Effects
Contraindications
- •Co-administration with any form of organic nitrates or nitric oxide donors (due to risk of severe hypotension).
- •Co-administration with guanylate cyclase stimulators (e.g., Riociguat).
- •Hypersensitivity to tadalafil or any components of the tablet.
- •Patients with severe cardiovascular disease for whom sexual activity is inadvisable.
- •Recent myocardial infarction (within 90 days) or stroke (within 6 months).
- •Uncontrolled hypertension or hypotension.
Drug Interactions
Nitrates
Potentiation of hypotensive effects; concomitant use is contraindicated.
Riociguat
Concomitant use is contraindicated due to severe hypotensive effects.
Alpha-Blockers
Risk of symptomatic hypotension; cautious use with dose adjustment of tadalafil or alpha-blocker.
Antihypertensives
Additive blood pressure lowering effects.
CYP3A4 Inducers (e.g., Rifampin)
Decreased plasma concentrations of tadalafil; reduced efficacy.
CYP3A4 Inhibitors (e.g., Ketoconazole, Ritonavir)
Increased exposure to tadalafil; lower tadalafil doses may be necessary.
Storage
Store in a cool, dry place, below 30°C. Protect from light and moisture. Keep out of reach of children.
Overdose
In studies of healthy subjects, single doses up to 500 mg of tadalafil were administered, and multiple daily doses up to 100 mg were given. Adverse events were similar to those seen at lower doses but generally more severe. In cases of overdose, standard supportive measures should be adopted as required. Hemodialysis contributes negligibly to tadalafil elimination.
Pregnancy & Lactation
Durevolis is not indicated for use in women. There are no adequate and well-controlled studies of tadalafil in pregnant or lactating women. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/fetal development, parturition, or postnatal development.
