Katora (Sildenafil Citrate)

Sildenafil citrate selectively blocks the phosphodiesterase type 5 enzyme, which results in higher levels of cyclic GMP. This chemical relaxes smooth muscle in the penis and pulmonary vessels, improving blood flow and facilitating erection or reducing pulmonary pressure.

The dose of Katora is determined by the prescribing clinician based on the individual’s medical condition, response to therapy, and any concomitant medications. Patients should follow the prescriber’s instructions and not alter the dose on their own.

Sildenafil citrate is not recommended for use during pregnancy or while breastfeeding because safety data are limited. Women who are pregnant, planning to become pregnant, or nursing should discuss alternative treatments with their healthcare provider.

To order Katora, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any required import documentation.

Katora (sildenafil) belongs to the PDE5 inhibitor class, similar to tadalafil and vardenafil. While all share the same mechanism, differences exist in duration of action, dosing frequency and specific side‑effect profiles, allowing clinicians to tailor therapy to individual patient needs.

Store Katora at temperatures below 25 °C, in its original packaging, and protect it from moisture and direct sunlight. Keep the product out of reach of children and do not use it after the expiration date printed on the label.

Katora is taken orally, usually with a glass of water. It may be taken with or without food, but a high‑fat meal can delay its onset of action. Patients should follow the timing instructions provided by their prescriber.

Serious risks include priapism (an erection lasting longer than four hours), sudden loss of vision or hearing, and cardiovascular events such as heart attack or stroke, especially in patients with pre‑existing heart disease. Immediate medical attention is required if any of these occur.

Katora should not be used by individuals taking nitrates, those with severe uncontrolled hypertension or hypotension, patients with known hypersensitivity to sildenafil, or men with certain retinal disorders such as retinitis pigmentosa. Contraindications should be confirmed by a qualified healthcare professional.
