The listed products belong to the category of ED (Erectile Dysfunction) medicines, which are primarily used to treat erectile dysfunction in men by improving blood flow to the penile region. Medicines such as Assurans, Pulmopres, and PAH tablets generally contain active ingredients like Sildenafil or similar phosphodiesterase type-5 (PDE-5) inhibitors that help relax blood vessels and enhance circulation, enabling a firm and sustained erection during sexual activity. Some of these medicines are also prescribed in certain cases of pulmonary arterial hypertension (PAH) due to their vasodilatory effects. The injectable form, such as Assurans injection, may be used in specific clinical conditions under medical supervision. These medications should always be taken as per a doctor’s prescription to ensure safe usage, proper dosage, and to avoid potential side effects or interactions with other treatments.
